GENERAL SAFETY RULES

WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.

Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

SAVE THESE SAFETY INSTRUCTIONS.

WORK AREA SAFETY

Keep work area clean and well lit. Cluttered or dark areas invite accidents.
Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases or dust. Power tools create sparks which may ignite the dust or fumes.

Keep children and bystanders away while operating a power tool. Distractions can cause you to lose control.

ELECTRICAL SAFETY

Power tool plugs must match the outlet. Never modify the plug in any way. Do not use any adapter plugs with earthed (grounded) power tools. Unmodified plugs and matching outlets will reduce risk of electric shock.
Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.

Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.
Do not abuse the cord. Never use the cord for carrying, pulling or unplugging the power tool. Keep cord away from heat, oil, sharp edges or moving parts. Damaged or entangled cords increase the risk of electric shock.

When operating a power tool outdoors, use an extension cord suitable for outdoor use. Use of a cord suitable for outdoor use reduces the risk of electric shock.
If operating a power tool in a damp location is un-avoidable, use a ground fault circuit interrupter (GFCI) protected supply. Use of a GFCI reduces the risk of electric shock.

PERSONAL SAFETY

Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use a power tool while you are tired or under the influence of drugs, alcohol or medication. A moment of inattention while operating power tools may result in serious personal injury.
Use personal protective equipment. Always wear eye protection. Protective equipment such as a respiratory mask, non-skid safety shoes and hearing protection used for appropriate conditions will reduce the risk of personal injury.
Prevent unintentional starting. Ensure the switch is in the off-position before connecting to power source and/or battery pack, picking up or carrying the tool. Carrying power tools with your finger on the switch or energizing power tools that have the switch on invites accidents.
Remove any adjusting key or wrench before turning the power tool on. A wrench or a key left attached to a rotating part of the power tool may result in personal injury.
Do not overreach. Keep proper footing and balance at all times. This enables better control of the power tool in unexpected situations.
Dress properly. Do not wear loose clothing or jewelry. Keep your hair and clothing away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.
WARNING! Read all safety warnings and all instructions. Failure to follow the warnings and instructions may result in electric shock, fire and/or serious injury.
Safety is a combination of common sense, staying alert and knowing how your item works. The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.
SAVE THESE SAFETY INSTRUCTIONS.
If devices are provided for the connection of dust extraction and collection facilities, ensure these are connected and properly used. Use of dust collection can reduce dust-related hazards.

POWER TOOL USE AND CARE

Do not force the power tool. Use the correct power tool for your application. The correct power tool will do the job better and safer at the rate for which it was designed.
Do not use the power tool if the switch does not turn it on and off. Any power tool that cannot be controlled with the switch is dangerous and must be repaired.
Disconnect the plug from the power source and/or the battery pack from the power tool before making any adjustments, changing accessories, or storing power tools. Such preventive safety measures reduce the risk of starting the power tool accidentally.
Store idle power tools out of the reach of children and do not allow persons unfamiliar with the power tool or these instructions to operate the power tool. Power tools are dangerous in the hands of untrained users.
Maintain power tools. Check for misalignment or binding of moving parts, breakage of parts and any other condition that may affect the power tool’s operation. If damaged, have the power tool repaired before use. Many accidents are caused by poorly maintained power tools.
Keep cutting tools sharp and clean. Properly maintained cutting tools with sharp cutting edges are less likely to bind and are easier to control.

Use the power tool, accessories and tool bits, etc. in accordance with these instructions, taking into account the working conditions and the work to be performed. Use of the power tool for operations different from those intended could result in a hazardous situation.
Use clamps to secure your workpiece to a stable surface. Holding a workpiece by hand or using your body to support it may lead to loss of control.
KEEP GUARDS IN PLACE and in working order.

SERVICE
Have your power tool serviced by a qualified repair person using only identical replacement parts. This will ensure that the safety of the power tool is maintained.

CALIFORNIA PROPOSITION 65 WARNING

Lead from lead-based paints.

Crystalline silica from bricks, cement, and other masonry products.
Arsenic and chromium from chemically treated lumber.

Your risk from these exposures varies depending on how often you do this type of work. To reduce your exposure to these chemicals, work in a well-ventilated area with approved safety equipment such as dust masks specially designed to filter out microscopic particles.

METAL LATHE SAFETY WARNINGS
WARNING! Do not let comfort or familiarity with the product replace strict adherence to product safety rules. Failure to follow the safety instructions may result in serious personal injury.

METAL LATHE SAFETY

This lathe is designed and intended for use by properly trained and experienced personnel only. If you are not familiar with the proper and safe operation of a lathe, do not use it until proper training and knowledge have been acquired.

Always wear eye protection and a face shield / dust mask when using the lathe.
Make sure all tools, chisels, and accessories are sharp enough for the task at hand before using them. Always use the right tool at the correct speed and feed rate.
Turn off and unplug the machine before doing any cleaning or maintenance. Use a brush to remove chips or debris. Never use your hands to remove excess material and debris.

Check the workpiece carefully for inconsistencies or obstructions. These types of blemishes may cause a safety risk during turning.
Rotate the workpiece by hand to check clearance before turning the machine on.
Select the appropriate speed for the task at hand. Start at a low speed and allow the lathe to ramp up to the operating speed before engaging any chisels, tools, or other carving accessories.

Never stop a rotating workpiece with your hand.
When turning between centers, make sure the head-stock and tailstock are tight and snug against the work-piece.
Always use a brush or rag to clear away chips from the workpiece. Using your hand can cause serious injury.

Always remove the key from the chuck jaws before operation.
Always wear a full face mask. If a tool or workpiece breaks off, it can create a hazard to users and onlookers.
Always use the right cutting tool. An improper tool could break or cause unwanted strain on the machine.

Never attempt to stop the lathe with your hand. You will lose your hand.
Always use the proper feed rate for your workpiece. An overly fast feed rate can damage the lathe or the workpiece.
Secure the workpiece properly, make sure the chuck is tight and secure on the workpiece before beginning to turn. A loose workpiece can shoot out and severely injure you or anyone around.

Use a tailstock to support long work stock. Anything more than 2.5 times as long as it is thick needs the tail-stock to support it.
Never operate the lathe with damaged parts.
Never turn a workpiece at RPMs that are too high for the work material. This can cause the cutting tool to break and launch off, injuring you or a bystander.

Never reverse motor direction while the machine is running.
Never change the lead screw feed direction while the machine is running.
Always ensure proper clearance between the work-piece and the cross slide, compound slide, and tool post.

Always disengage automatic feed after a cutting pass, even if it is the final cut. You can forget and hurt yourself upon next use.
Always tie up long hair. Do not wear any loose /hanging clothing. Even aprons can be hazards when improperly secured.
Remove any and all jewelry, rings, watches, etc. to avoid getting them caught in the lathe.

ELECTRICAL INFORMATION

GROUNDING INSTRUCTIONS
In the event of a malfunction or breakdown, grounding provides the path of least resistance for an electric current and reduces the risk of electric shock. This tool is equipped with an electric cord that has an equipment grounding conductor and a grounding plug. The plug MUST be plugged into a matching outlet that is properly installed and grounded in accordance with ALL local codes and ordinances.

Do not modify the plug provided. If it will not fit the outlet, have the proper outlet installed by a licensed electrician.
Improper connection of the equipment grounding conductor can result in electric shock. The conductor with the green insulation (with or without yellow stripes) is the equipment grounding conductor. If repair or replacement of the electric cord or plug is necessary, DO NOT connect the equipment grounding conductor to a live terminal.

Check with a licensed electrician or service personnel if you do not completely understand the grounding instructions or whether the tool is properly grounded.
Use only three-wire extension cords that have three-pronged plugs and outlets that accept the tool’s plug. Repair or replace a damaged or worn cord immediately.

CAUTION! In all cases, make certain the outlet in question is properly grounded. If you
are not sure, have a licensed electrician check the outlet.

GUIDELINES AND RECOMMENDATIONS FOR EXTENSION CORDS
When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. The table below shows the correct size to be used according to cord length and ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.

AMPERAGE	REQUIRED GAUGE FOR EXTENSION CODS
AMPERAGE	25 ft.	50 ft.	100 ft.	150 ft.
4A	18 Gauge	16 Gauge	16 Gauge	14 Gauge

Examine extension cord before use. Make sure your extension cord is properly wired and in good condition. Always replace a damaged extension cord or have it repaired by a qualified person before using it.
Do not abuse extension cord. Do not pull on cord to disconnect from receptacle; always disconnect by pulling on plug. Disconnect the extension cord from the receptacle before disconnecting the product from the extension cord. Protect your extension cords from sharp objects, excessive heat and damp/wet areas.

Use a separate electrical circuit for your tool. This circuit must not be less than a 12-gauge wire and should be protected with a 15A time-delayed fuse. Before connecting the motor to the power line, make sure the switch is in the OFF position and the electric current is rated the same as the current stamped on the motor nameplate. Running at a lower voltage will damage the motor.

NOTE: Before assembling, carefully wipe off all grease and rust-protectant coating with a soft cloth. Use kerosene or acetone to fully remove the grease and coating. Apply a light coat of good-quality paste wax to all machined surfaces to prevent rusting and ensure ease of movement between parts.

Use the four M6x16 pan-head screws to attach the chip tray and rubber feet to the tapped holes in the underside of the lathe body. Insert the screws through the feet, through the chip tray, and into the lathe. Tighten using Phillips-head screwdriver (not included). We strongly recommend that to provide maximum stability and safety, users should secure the lathe to a firm foundation as described under “Mounting the Lathe” below.

Attach the plastic handles to the rims of the manual feed and tailstock feed handwheels. Ensure the nuts are tight and the handles spin freely about the bolts without excessive end play.

The carriage, cross slide, and compound slide adjustments are all factory-set to ensure smooth movement in both directions. However the adjustments may have been misaligned during transportation. This will be indicated by stiff or erratic movement. Refer to “ADJUSTING THE GIBS” on page 20 for adjustment methods.

All hex keys and wrenches necessary to carry out various adjustments are supplied together with a chuck key for the 3-jaw chuck. The fuse socket (21) is located on the main control panel.

OPERATION

MOUNTING THE LATHE (FIG. 1)
The lathe should be mounted on a strong, heavy work-bench. Take the necessary precautions when moving the lathe. Assistance may be required. Bolt the machine firmly to the workbench using the tapped holes. To do this remove the 6mm screws securing the rubber feet in place. Drill four 6mm (0.25-inch) clearance holes in the worktop and find washers and 6mm screws long enough to securely hold the unit in place.

HEADSTOCK
The headstock (Fig. 2 – 1) contains the motor, pulleys and the drive belt that turn the spindle used to create your workpiece. The spindle (Fig. 2 – 2) has a MT3 taper for use in conjunction with a face plate or chuck. The spindle has a flange attached with 6 holes arranged to mount different fixtures, such as chuck jaws and face plates. The speed of the spindle is adjusted using the speed control knob (Fig. 2 – 3) on the control panel. The speed ranges can be swapped between two ranges with the lever (Fig. 2 – 4) on the back of the headstock.

WARNING! Do not change the speed range during operation.

CARRIAGE
The carriage (Fig. 3 – 1) is the portion of the lathe that moves the cross slide (Fig. 3 – 2) and compound slide (Fig. 3 – 3) across the bed. It can be manually fed with the handwheel (Fig. 3 – 5), or driven with the lead screw (Fig. 3 – 4) by engaging the half nuts with the automatic feed lever (Fig. 3 – 6).

CROSS SLIDE
The cross slide (Fig. 3 – 2) is used to move the tool post and cutting tool across the bed, perpendicular to the lead screw (Fig. 3 – 4) and the center axis of the spindle. The cross slide is adjusted via a handle (Fig. 3 – 7) with precision tick marks, each indicating 0.001”. This scale will rotate with the handle when it is turned to feed the cross slide back and forth. Before beginning turning, perform the following steps to adjust and zero your cross slide:

Turn the handle counterclockwise to back the cross slide about 0.015” away from your starting point, then slowly turn the handle clockwise until the cross slide returns to the starting position. This removes any play in the slide and helps make the scale more accurate.
Hold the handle steady. With your other hand, rotate the scale so the “0” lines up with the “0.000” mark on the cross slide. From this point, the slide will remain accurate as long as you only move it forward (toward the splash guard on the back of the lathe).
Any time you back the slide away from your work-piece, you will have to repeat steps 1 and 2 before moving the cross slide forward again for the next cut.

COMPOUND SLIDE
The compound slide (Fig. 4 – 1) works similarly to the cross slide, with a small handle (Fig. 4 – 2) and a scale with tick marks every 0.001”. The compound slide can be fed back and forth with this handle, similar to the cross slide. It can also be rotated to an angle of your choice and fed back and forth along this angle.

ADJUSTING THE COMPOUND SLIDE

Rotate the handle to move the compound slide back and expose the two screws (Fig. 5 – 1). Loosen these two screws with one of the included hex wrenches.

Rotate the compound slide to the desired angle and retighten the bolts to lock it in place.
Turn the handle until your slide is at its starting point. Then back the slide 0.015” from the starting point.
Slowly turn the handle to feed the slide forward until it returns to the starting point.

Hold the handle in place and rotate the scale so the “0” and “0.000” lines match and the scale is properly zeroed.
Repeat steps 3-5 for each cut and each time you adjust the slide in order to get the most accurate cuts.

CARRIAGE FEED
The feed of the carriage along the axis of the spindle can be done manually, or automatically by the lead screw and gear train.

TO MANUALLY FEED THE CARRIAGE
Disengage the half nuts from the lead screw by pulling UP on the feed lever (Fig. 4 – 3). Use the handle wheel on the carriage (Fig. 4 – 4) to move it along the bed. Turning it clockwise will move it away from the spindle and turn-ing it counter-clockwise will move it towards the spindle.

TO AUTOMATICALLY FEED THE CARRIAGE

Set the carriage to your starting point.
While the unit is still turned off, set the lead screw direction lever (Fig. 6 – 1) to either left feed or right feed, using the label next to the lever. Choose your preferred direction based on the sticker next to the Lever.
Turn the lathe on and set it to the necessary RPM using the speed control knob.
Push the feed lever down to engage the lead screw and the automatic feed function.
Once the tool’s pass is finished, pull up on the lever to disengage the lead screw and the automatic feed. Move the carriage back to the desired starting point, then push the feed lever down again and repeat.

NOTE: Increasing the spindle speed using the speed control knob will also increase the lead screw feed rate proportionally.

TAILSTOCK
The tailstock (Fig. 7) is located on the bed opposite of the headstock. It can be moved along the bed by loosening the 17mm nut (Fig. 7 – 4) and pushing the tailstock to the desired position. When it is in the desired spot, tighten the 17mm nut to lock it in place. The tailstock is equipped with an MT2 taper to use with appropriate tools, like the included dead center, or an MT2 drill chuck. The tailstock arrives properly aligned to the headstock from the factory. This allows the use of dead or live centers for turning between centers, as well as on-center drilling if using a drill chuck. The tailstock quill is self-ejecting.

TAILSTOCK COMPONENTS

Tailstock Handwheel: Feeds the quill in and out of the tailstock into the workpiece. Use to push a center into the workpiece to hold it level horizontally, or to feed a drill into the workpiece to create a hole.
Offset Set Screw: Locks the tailstock position to allow for offset alignment (see next page).
Offset Cap Screw: Allows tailstock alignment to be adjusted to right or left of center (underside of tailstock).
Tailstock Lock Nut: Secures the tailstock in place on the bed.
Quill: Holds MT2 tapered tools in the tailstock.
Quill Lock: Secures the quill in place.

USING A CENTER WITH THE TAILSTOCK
If you are turning a workpiece with stock that hangs more than 2.5 times its diameter beyond the chuck jaws, it is necessary to support the other end with a center and the tailstock. For projects that allow low RPM turning, a dead center is okay. If higher RPMs are necessary, we recommend investing in a live center, which is equipped with a bearing. To install

Check the center and tailstock quill for any dirt, dust, debris or oil. Wipe both down, as excessive oil or dirt will not allow the tapers to interlock.
Turn the tailstock handwheel until the quill protrudes approximately 1/2” inch from the tailstock.
Slide the center into the quill until it is snug; the tapers will keep the center in place. Keep the quill extended between 0 and 1.5 on the quill scale to keep it secure.
To remove the center, use the tailstock handle to retract the quill into the tailstock completely. This forces the center out of the quill. Hold the head of the center with your hand to catch it as the center becomes loose.

OFFSETTING YOUR TAILSTOCK
WARNING! The tailstock comes from the factory properly aligned with the headstock.

The tailstock can also be used in an offset position to help turn tapers on a work piece. Adjusting the tailstock into an offset position requires removing the tailstock from the bed and adjusting the offset screw on the bottom of the tailstock. To properly offset the tailstock follow these steps (Fig. 8):

Use a 17mm wrench or socket to loosen the lock nut that holds the tailstock in place. Remove the stop screw on the rear of the end of the bed (p. 8, item 18) using a 4mm hex wrench. Then slide the tailstock off the bed.
Loosen the offset set screw (Fig. 7 – 2) on the back of the tailstock, below the handle.
Loosen the offset cap screw (Fig. 7 – 3) on the bottom of the tailstock. Only loosen it enough so the tailstock can slide.
Slide the tailstock back onto the bed and adjust it to the desired offset.
Tighten the offset setscrew to hold the tailstock at the proper offset position.
Slowly and carefully slide the tailstock off the bed and tighten the offset cap screw on the bottom.
Slide the tailstock back onto the bed, lock it in to the desired position and check your tolerances to makes sure it is in the desired offset.
Repeat the previous steps in order to adjust the offset to the exact position necessary for your workpiece. Rein-stall the stop screw on the end of the bed when finished.

TOOL POST
The tool post is used to hold your cutting tools and run the cutting edge along the workpiece you are turning. The tool post can hold four tools at a time and has 4 preset stops at 90 degree intervals. It can also be set at any angle in between these four presets. To install a cutting tool into the tool post follow these steps

Determine which cutting tool will create the desired cut profile.
Loosen the screws in the top of the tool post on the edge you will place the cutting tool. Make sure the tool will be secured by a minimum of two of these screws.
Place the tool under the screws and loosely tighten them, making sure it is perpendicular (or at the proper angle) to the axis of the workpiece.
Align the tip of the tool with the centerline of the workpiece. If the workpiece centerline is higher, place shims under the tool to raise its height. This machine uses 5/16” (8mm) tools. To determine if the tool tip is even with the centerline, check the tool tip against the tip of the center in the tailstock. If the two tips are even or the tool tip is below the center tip, the tool is the proper height. If the two tips are even or the tool tip is below the center team, the tool is the proper size for the lathe. If the tool tip is below the center tip, it will need to be shimmed up to the height of the center tip, otherwise you will see a small “button” on the workpiece when parting off. If the tool tip is higher than the center tip, the tool is the wrong size for this lathe.

NOTE: You may also install an aftermarket quick-change tool post, size 0XA, if desired. The mounting bolt size is M10x65mm.

GEAR TRAIN
WARNING! Before making any of these adjustments, turn off and unplug the lathe from its power source.

NOTE: This lathe is designed for use with plastic gears. This is intentional, so that if you make a mistake and a gear or the lead screw binds up, a gear will break, rather than the mo-tor. The gears are much easier and less expensive to replace.

The gear train is located on the headstock opposite the spin- BBB dle. The drive gears are located Cinder a cover secured by two DDD socket head cap screws. The gear train is used to drive the lead screw’s speed, allowing Adjuster the auto-feed function to operate. As the gear train turns, it turns the lead screw which moves the carriage across the bed of the lathe. The direction is set using the lead screw direction lever. Adjusting it to forward will send the carriage towards the headstock. Reverse sends it away, and neutral disengages the lead screw so the carriage can be manually fed.

The feed rate of the lead screw can be set by changing the gears in the gear train (Fig. 8). Switching the diameter of the gears and the order of the gears will change the lead screw’s speed, allowing for different threads to be turned with the lathe. The Threading Chart to the right shows the gear arrangements to use to achieve different threads per inch (TPI) or metric pitches when using the lead screw.

To change the gears

Using the 4mm hex wrench, remove the 2 mounting screws on the gear cover. Then remove the gear cover.
Loosen the adjustment nut at the bottom of the gear train to disengage the gears from one another. Loosen the socket head cap screws that hold each gear (or gear pair) on its shaft. Remove the necessary gears and replace them with the appropriate gears. That is, the gears that have the proper number of teeth in the positions called for (30, 40, 60, and 65 teeth). Note that some configurations do not require gears in every position, and some require you to move the bushings from one shaft to another for gears to properly fit in place.
Position the gears so their teeth will mesh together properly once the adjuster is tightened.

NORMAL OPERATION
Before starting a turning, always plan your work ahead of time. Create a drawing or plan with all of the dimensions you desire for the workpiece. Make sure to have all the measuring tools you will need to double and triple check your cuts. Ensure that the feed rate, depth of cut (DOC), and spindle speed (RPM; depends on material, cutting tool material and profile, DOC, desired surface finish, workpiece geometry, etc.) are all proper for your operation. To avoid stalling the motor, we recommend that the DOC never exceed 0.5mm (0.0196 in), and should be kept below 0.25mm (about 0.01 in) whenever possible. Reduce spindle speed when taking a deeper cut.

Place the work into the chuck or attach to the faceplate. If necessary, use the tailstock center to support the opposite end. If the tailstock is not needed, it can be removed completely by removing the stop screw and sliding the tailstock off the bed.
After you have the work planned out, select the necessary cutting tools for the feature you wish to create and mount them to the tool post. Make sure the tool tips are aligned with the center line of the workpiece, or slightly below them.

Mark the end point for the cut on the work piece using a scriber. Line up the cutting tool with the end point and feed in the cross slide until it just touches the surface of the workpiece. Then turn the spindle by hand to make sure there is no interference between the carriage, cross slide, tool post, cutting tool, or chuck. It may be necessary to adjust the compound slide or the workpiece in the chuck to get the proper amount of clearance.

When you have assured there is adequate clearance, back the cross slide away from the work piece and move the carriage away from the head stock. Next zero out the cross-slide

Feed the cross slide and the cutting tool to the starting position of the cut.
Back the cross slide 0.015” away from the work piece.
Slowly feed the cross slide back to the starting point.
Hold the handle to move the cross slide in place with one hand, and turn the dial of the gauge to make the 0 and the 0.000 marks line up. The cross slide and cutting tool are now zeroed out.
If you have to back feed the cross slide at all, repeat steps 1 through 4.

NOTE: Before each pass of the cutting tool, it is recommended to add cutting oil to the work piece to reduce heat and friction. Make sure to periodically add oil to the work piece as needed while turning.

MANUAL FEED
Double check the following before you begin turning

The auto-feed lever is in the UP position, so the carriage half nuts are disengaged from the lead screw.
The Auto Feed Direction Lever is in NEUTRAL.
You are in the appropriate speed selection of HIGH/LOW for the material you are turning.

To know the proper RPM will take some experience. Harder metals should use a slower RPM while softer can use a little faster RPM. If you are unsure, it is better to go slower than risk damage to the work, the cutting tool or the lathe by using too high of an RPM. Feed rate and DOC are also very important. A deeper DOC needs a slower feed rate and slower RPM, and vice versa.

Once you are ready to begin, switch the machine ON and set the RPM to your desired level. Slowly feed the cutting tool into the work piece using the carriage handle. Slowly feed the cutting tool across the work piece until you reach the marked end point. Retract the cross slide and cutting tool at this point one or two full revolutions. Return the carriage to the starting point, and then feed the tool back in the same number of revolutions plus a small additional feed rate in. Repeat this process until you have the desired amount of material cut away.

AUTOMATIC FEED
Once you have the cross slide set in position double check the following

The auto feed direction lever is set to FORWARD.
The auto feed lever is disengaged from the lead screw.
You are in the appropriate speed selection range of HIGH/LOW.
The gear train is in the proper configuration, as this determines the feed rate of the lead screw. The factory setting is okay for normal turning, but if you have been cutting screw threads you will need to reset the gear train to the proper configuration.

CUTTING WITH THE AUTOMATIC FEED
NOTE: Ensure the DOC is appropriate for the cutting tool material, workpiece material, etc.

Position the cutting tool past the end of the workpiece, away from the tailstock. Make sure the tool is set to the proper cutting depth. Always do shallow cuts, as cutting too deep too fast will damage the work piece, your cutting tool, and your lathe. It is recommended to keep the cuts to 0.010” (0.25mm) or less at a time.
Double check that all the feed levers are set properly.
Turn the unit ON and set the spindle speed to the desired rate. Push the autofeed lever down to engage the half nut with the lead screw.
Watch your cutting tool. When it reaches the end, quickly press UP on the auto feed lever and make sure it stays disengaged from the lead screw.
Retract the cutting tool one or two turns using the cross slide handle. Feed the carriage back to the starting point, and feed the tool back in one or two turns plus the additional cutting depth.
When ready for the next pass, engage the auto feed lever and repeat the previous steps until you have removed the desired amount of material.

BEVEL CUTTING
In order to perform a bevel cut, it is necessary to use the compound slide as well as the cross slide. To align the compound slide for a bevel cut, align it to the proper angle following the procedure in the “Compound Slide” section on page 12.
Once the compound slide is aligned to the proper angle, follow these steps to create the bevel

Mark your end point of the bevel if necessary, using the methods for a normal turning.
Set and zero out the cross slide to the proper starting point.
Turn the lathe on and set the spindle to the appropriate RPM.
Use the handle on the compound slide to feed the cutting tool along the end of the workpiece. This will create the bevel cut at the angle you set it to.
Back off the cutting tool 2 turns and reset the compound slide to the starting point. Feed the cutting tool back in to the cutting depth.
Repeat until your bevel is the desired length and position.

TO CUT THREADS

Adjust the compound slide so the tool is at the appropriate angle for the desired thread.
Place the tool tip so that it is vertically centered and perpendicular to the work-piece.
Engage the thread dial with the lead screw. The thread dial is located next to the auto-feed lever on the carriage. There is a socket-head cap screw on the side; loosen the screw using one of the included hex wrenches and adjust the body of the thread dial so that its gear meshes with the threads on the lead screw. Tighten the socket head cap screw, ensuring that the gear stays engaged with the lead screw threads.
Use the gear ratio charts to determine the proper gear ratio and install the proper gears (See “Gear Train” on page 15).
Turn the lathe on and set the RPM using the speed control knob. Make sure the lead screw is feeding in the proper direction by engaging the feed lever. When you are sure it is going in the right direction disengage the feed lever and turn off the lathe. Ensure that the carriage is beyond the end of the workpiece.
Read the settings off the thread dial chart (left) to get the proper setting for the thread dial. Make sure the thread dial always engages the half nut on the same mark for every pass of the cutting tool. If you don’t do this, you may cut off threads created in your previous cut. That is, the lever needs to be pushed down at the same point in order to cut threads correctly. If you engage the lever when the dial is not pointing to an indicator mark, you may stall the lead screw, which will cause it to drop into Neutral and stop.

CHANGING THE JAWS IN YOUR CHUCK (FIG. 9)

Make sure your lathe is turned off and unplugged.
Insert the chuck key into the square hole of the chuck. Turn the chuck key counterclockwise until all of the jaws come out of the chuck.
Clean out each slot in the chuck making sure all dirt and debris are removed.
Each jaw has a number or letter (1, 2, 3 or A, B, C) that corresponds to a number in the slot.
Take Jaw #1 and insert the chuck key into the chuck. Turn the key clockwise while looking directly at the chuck so you can see inside the slot. You will see the beginning of a lead thread on the scroll of the chuck pass the opening, heading counter-clockwise.
Insert Jaw #1 into this slot and turn the chuck key until the thread engages the jaw.
Repeat these steps for jaws 2 and 3. Make sure to always insert the jaws in order.

REMOVING A CHUCK OR FACEPLATE (FIG. 10)

Turn off and unplug your lathe! It is recommended to place a piece of plywood over the bed underneath the spindle in order to protect the bed if you drop the chuck/faceplate.
Hold the chuck or faceplate with your hand while using a 10mm wrench with your other hand to loosen and remove the three hex nuts on the back of the spindle plate.
Pull the chuck/faceplate slowly off the spindle. It may be necessary to tap the back surface of the faceplate/chuck with a rubber mallet to get it off the spindle.
Make sure to keep track of the studs used for positioning the chuck/faceplate, and set the piece aside.

INSTALLING THE CHUCK OR FACEPLATE

Insert the guide studs into the chuck/faceplate you wish to install. To do this, make sure the studs extend at least ½” from the surface of the chuck/faceplate.
Align the studs with the holes on the spindle and secure the chuck/faceplate in place with the nuts using a 10mm wrench.

ADJUSTING THE GIBS
Although the factory setting should be fine, if you are having trouble feeding the compound or cross slide, you may want to adjust the gib screws. To adjust the gib you will need a 2mm hex wrench and a 7mm combination wrench. Follow these steps to adjust the gibs

Turn off and unplug the lathe.
Loosen the three locknuts.
Test the sliding movement. Tighten and loosen the set screws as necessary. The slides should move smoothly without play. Readjust the set screws as needed.
Tighten the locknuts to keep the gibs set

CHECKING AND REPLACING MOTOR BRUSHES
The wear on the carbon brushes depends on how frequently and how heavily the tool is used. To maintain maximum motor efficiency, we recommend inspecting the two carbon brushes every 50 hours of operation.

NOTE: Replacement carbon brushes (part no. 3455-137.1) can be ordered at wenproducts.com . Only genuine WEN replacement brushes designed specifically for your tool should be used. Carbon brushes are not covered under the two-year warranty.

To replace the brushes for the lathe’s motor

Turn off and unplug the lathe.
Use a flat-head screwdriver to remove the front and rear brush caps from the motor. One can be accessed through the hole in the front of the bed. The other can be accessed from the back of the headstock, where the motor is exposed.
Remove the motor brushes and measure them. If they are worn down to 3/16” or less, replace them with new ones. If not, reinstall them in the motor.
Insert the new motor brushes. Ensure there is good contact between the new brushes and the motor commutator.
Reattach the brush caps.

NOTE: Both brushes should be replaced simultaneously.

MAINTENANCE

Before each use make sure to check all of the parts of the lathe for any loose bolts or connections. Leave the gear cover on to prevent chips from interfering with the geartrain. Make any adjustments to connections as necessary to ensure all the parts are connected and will stay together during operation. Check all of the cutting tools to make sure they are sharp. If the edge is dull, or has any nicks or cuts, either sharpen it or replace it. Dull or damaged cutting tools are a hazard and should never be used.
Every time you use your lathe, make sure to check that all work surfaces are clean and undamaged. If there are any chips or dents in the surface, work them out with an oil stone. Check that all of the moving parts pass over each smoothly and can be moved without any interference.
Use your oil can to squirt a few drops of oil into the oilways of both bearings on the ends of the leadscrew. Do the same for the oil way on the compound slide. The opening for this oilway is located between the two hex screws to adjust the slide.
After use, make sure to clean away all metal shavings. Use a rag or brush to wipe away. It is recommended to wear gloves while doing this to prevent getting any small metal shavings stuck in your hand. Make sure to wipe all of the debris and dirt off the machine. Do not use an air compressor, as this can force shavings into the moving parts of the lathe and cause damage. Make sure to remove all cutting tools and store in a safe place. Once the lathe is clean it is recommended to lightly oil all of the surfaces to prevent any corrosion and keep the parts moving smoothly.

AFTER EACH USE

Clean all machine surfaces, including the chuck, and apply a thin layer of oil.
Put oil in each bearing on the lead screw.
Clean and oil the sliding surfaces of the bed, cross slide and compound slide.

EVERY 4 TO 6 MONTHS

Apply white lithium grease to the cross slide and compound slide lead screws.
Apply white lithium grease to all the drive gears.
Apply white lithium grease to the tailstock quill and screw.
Grease all of the transmission gears with a spray on grease.
