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 as shown in Fig. A. 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.

⚠️ WARNING: This tool is for indoor use only. Do not expose to rain or use in damp locations.

Make sure your extension cord is in good condition. 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 above shows the correct size to be used according to cord length and nameplate ampere rating. When in doubt, use a heavier cord. The smaller the gauge number, the heavier the cord.

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.

Protect your extension cords from sharp objects, excessive heat and damp/wet areas.

Use a separate electrical circuit for your tools. This circuit must not be less than a #12 wire and should be protected with a 15 A 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.

⚠️ WARNING: This tool must be grounded while in use to protect the operator from electric shock.

BENCH MOUNTING THE SAW (Fig. 7-8)

Before operating the saw, it must be firmly mounted to a workbench or another rigid frame. Use the base of the saw to mark and pre-drill the mounting holes. If the saw is to be used in one location, permanently secure it to the work surface using wood screws if mounting to wood. Use bolts, washers, and nuts if mounting into metal. To reduce noise and vibration, install a soft foam pad (not supplied) between the scroll saw and the workbench.

Note: Mounting hardware is not included.

⚠️ WARNING - to reduce the risk of injury:

• When carrying the saw, hold it close to your body to avoid injury to your back. Bend your knees when lifting the saw.
• Carry the saw by the base. Do not carry the saw by the power cord.
• Secure the saw in a position where people cannot stand, sit, or walk behind it. Debris thrown from the saw could injure people standing, sitting, or walking behind it.
• Secure the saw on a firm, level surface where the saw cannot rock. Make sure there is adequate room for handling and properly supporting the work piece.

BLADE GUARD FOOT ADJUSTMENT (Fig. 7 and 8)

When cutting at angles, the blade guard foot should be adjusted so it is parallel to the table and rests flat above the work piece.

• 1. To adjust, loosen the screw (2), tilt the foot (1) so it is parallel to the table, and tighten the screw.
• 2. Loosen the height adjustment knob (3) to raise or lower the foot until it just rests on top of the work piece. Tighten the knob.

(Diagram description: Figure 7 and 8 show close-ups of the blade guard foot adjustment. Figure 7 illustrates loosening screw (2) to tilt foot (1). Figure 8 shows adjusting height with knob (3).)

ALIGN THE BEVEL INDICATOR (Fig. 3-6)

The bevel indicator has been factory adjusted. It should be rechecked prior to use for best operation.

• 1. Remove the blade guard foot (1) using a Phillips head screwdriver (not included) to loosen the screw (2).
• 2. Loosen the table bevel lock knob (3) and move the table until it is approximately at a right angle to the blade.
• 3. Loosen the locking nut (5) on the table adjusting screw (6) under the table by turning it counter-clockwise. Lower the table adjusting screw by turning it clockwise.
• 4. Use a combination square (7) to set the table exactly 90° to the blade (8). If there is space between the square and blade, adjust the table angle until the space is closed.
• 5. Lock the table bevel lock knob under the table (3) to prevent movement.
• 6. Tighten the adjusting screw under the table until the tip of the screw touches the table. Tighten the lock nut.
• 7. Loosen the screw (4) holding the bevel scale pointer and position pointer to 0°. Tighten the screw.

(Diagram description: Figures 3-6 illustrate the process of aligning the bevel indicator. Figure 3 shows screw (2) and knob (3). Figure 4 shows table adjustment with square (7) and blade (8). Figure 5 shows locking nut (5) and adjusting screw (6). Figure 6 shows the final position of the blade guard foot (1) and screw (2).)

ADJUSTING THE DUST BLOWER (Fig. 9)

For best results, the dust blower tube (1) should be adjusted to direct air at both the blade and the work piece.

(Diagram description: Figure 9 shows the dust blower tube (1) positioned near the blade.)

SAWDUST COLLECTION PORT (Fig. 10 and 11)

This scroll saw allows a hose or vacuum accessory (not provided) to be connected to the dust chute (2). If excessive sawdust buildup occurs inside the base, use a wet/dry vacuum cleaner or manually remove sawdust by removing the screws (3) and metal plate on the left side of the saw. Reattach the metal plate and screws before starting the saw. This will keep your saw cutting efficiently.

(Diagram description: Figure 10 shows the dust chute (2) for connecting a vacuum hose. Figure 11 shows the access panel (3) on the left side of the base for manual sawdust removal.)

BLADE SELECTION (Fig. 12)

This scroll saw accepts 5" length pin end and pinless blades, with a wide variety of blade thicknesses and widths. The type of material and intricacies of cutting operations will determine the number of teeth per inch. Always select the narrowest blades for intricate curve cutting and the widest blades for straight and large curve cutting operations. The following table represents suggestions for various materials. Use this table as an example, but with practice, personal preference will be the best selection method.

When choosing a blade, use very fine, narrow blades to scroll cut in thin wood 1/4" thick or less. Use wider blades for thicker materials but this will reduce the ability to cut tight curves. A smaller blade width can cut circles with smaller diameters.

Note: Thinner blades will have more possibilities for blade deflection when cutting angles are not perpendicular to the table.

(Diagram description: Figure 12 shows two examples of scroll saw blades, one with pins and one without, illustrating different tooth configurations and lengths.)

BLADE CARE

To maximize the life of your scroll saw blades:

• 1. Do not bend blades when installing.
• 2. Always set proper blade tension.
• 3. Use the right blade (see instruction on replacement blade packaging for proper use).
• 4. Feed the work correctly into the blade.
• 5. Use thin blades for intricate cutting.

? CAUTION: Any and all servicing should be performed by a qualified service center.

BLADE REMOVAL AND INSTALLATION (Fig. 13 to 15)

⚠️ WARNING: To prevent personal injury, always turn saw OFF and disconnect the plug from the power source before changing blades or making adjustments.

This saw uses pinned and pinless blades. Pinned blades are thicker for stability and for faster assembly. They provide faster cutting on a variety of materials.

Note: When installing pinned blades, the slot on the blade holder must be slightly wider than the thickness of the blade. After the blade is installed, the blade tension mechanism will keep it in place.

• 1. To remove the blade, loosen the tension on it by lifting up the blade tension lever. Turn the lever counterclockwise to loosen the blade holder if necessary.
• 2. Remove the table insert. Carefully pry up on the table insert to remove.
• 3. Push down on the upper blade holder to remove the blade from the holder (2). Remove the blade from the lower blade holder (3).

? CAUTION: Install the blade with the teeth pointing downward.

• 4. To install the blade, hook the blade in the recess of the lower blade holder (3).
• 5. While pushing down on the upper blade holder, insert the blade into the slot of the holder.
• 7. Move the blade tension lever down and make sure the blade pin is properly positioned in the blade holders.
• 8. Adjust the blade to the desired tension. Turning the blade tension knob clockwise tightens the blade and turning the knob counterclockwise loosens the blade.
• 8. Place the table insert back into place.

(Diagram description: Figures 13-15 illustrate blade removal and installation. Figure 13 shows lifting the blade tension lever (1). Figure 14 shows the upper blade holder (2) and lower blade holder (3). Figure 15 shows the blade being hooked into the lower holder (3) and inserted into the upper holder.)

ADJUSTING THE BLADE DIRECTION (Fig. 16 & 17)

The WEN Scroll Saw accepts pinned blades in two different positions to accommodate a wider variety of workpieces. Notice the two various slots for pinned blades that appear on the head of the saw (Fig. 16). Pinned blades can be placed in either of the two slots, changing the direction of the blade by 90 degrees. A coinciding slot exists for each holder underneath the plate.

(Diagram description: Figure 16 shows the head of the saw with two slots for pinned blades. Figure 17 shows the upper and lower blade attachments.)

INSTALLING PINLESS BLADE (Fig. 18 & 19)

• 1. Remove the existing blade and table insert (see Blade Removal and Installation).
• 2. To install the pinless blade, loosen the thumb screw on the lower blade attachment.
• 3. Install the blade into the lower blade attachment and tighten the thumb screw. Hook the lower blade attachment onto the curve of the bottom blade holder found underneath the table (1).
• 4. Place the insert back into the table after carefully inserting the blade through the table insert slot and the pilot hole of the workpiece.
• 4. Insert the blade into the upper blade attachment. Tighten the upper thumb screw to secure the blade.
• 5. Hook the upper blade attachment onto the top curve of the upper blade holder (2).
• 6. Move the blade tension lever down and make sure the blade attachments are properly secured and tensioned onto the machine.

(Diagram description: Figures 18 and 19 illustrate installing a pinless blade. Figure 18 shows the lower blade attachment (1) and upper blade attachment. Figure 19 shows the upper blade attachment being hooked onto the upper blade holder (2).)

Operation

RECOMMENDATIONS FOR CUTTING

A scroll saw is basically a curve-cutting machine. It can also be used for straight cutting and beveling or angle cutting operations. Please read and understand the following items before attempting to use the saw.

• 1. When feeding the work piece into the blade do not force it against the blade. This could cause blade deflection. Allow the saw to cut the material by guiding the work piece into the blade as it cuts.
• 2. The blade teeth cut material ONLY on the down stroke.
• 3. Guide the wood into the blade slowly because the teeth of the blade are very small and remove wood only on the down stroke.
• 4. There is a learning curve for each person using this saw. During that period of time it is expected that some blades will break until you learn how to use the saw.
• 5. Best results are achieved when cutting wood one inch thick or less.
• 6. When cutting wood thicker than one inch, guide the wood slowly into the blade and take extra care not to bend or twist the blade while cutting in order to maximize blade life.
• 7. Teeth on scroll saw blades wear out and the blades must be replaced frequently for best cutting results. Scroll saw blades generally stay sharp for 1/2 hour to 2 hours of cutting.
• 8. To get accurate cuts, be prepared to compensate for the blade's tendency to follow the wood grain.
• 9. This scroll saw is primarily designed to cut wood or wood products. For cutting precious and non-ferrous metals, the variable control switch must be set at very slow speeds.
• 10. When choosing a blade, use very fine, narrow blades to scroll cut in thin wood 1/4" thick or less. Use wider blades for thicker materials. This, however, will reduce the ability to cut tight curves.
• 11. Blades wear down faster when cutting plywood or very abrasive particle board. Angle cutting in hardwoods also wears blades down faster.

ON/OFF & SPEED CONTROL SWITCH (Fig. 20)

Always wait for the saw to come to a complete stop before restarting.

• 1. To turn the saw on, flip the ON/OFF switch to ON (2). When first starting the saw, it is best to move the speed control knob (1) to the middle speed position.
• 2. Adjust the blade speed to the desired setting between 400 to 1600 strokes per minute (SPM). Turning the control knob clockwise increases speed; turning it counterclockwise reduces speed.
• 3. To turn the saw off, flip the ON/OFF switch back to OFF (2). Note: You can lock the scroll saw by removing the tip of the switch. Just pry off the switch lock with your fingernails to prevent accidental operation.

⚠️ WARNING: To avoid injury from accidental start-ups, always turn the switch OFF and unplug the scroll saw before moving the tool, replacing the blade, or making adjustments.

(Diagram description: Figure 20 shows the ON/OFF switch (2) and speed control knob (1).)

FREEHAND CUTTING (Fig. 21)

• 1. Lay out desired design, or secure design to the work piece.
• 2. Raise the blade guard foot (1) by loosening the height adjustment knob (2).
• 3. Position the work piece against the blade and place the blade guard foot against the top surface of the work piece.
• 4. Secure the blade guard foot (1) by tightening the height adjustment knob (2).
• 5. Remove the work piece from the blade prior to turning the scroll saw ON.

? CAUTION: In order to avoid uncontrollable lifting of the work piece and to reduce blade breakage, do not turn the switch on while the work piece is against the blade.

• 6. Slowly feed the work piece into the blade by guiding and pressing the work piece down against the table.

? CAUTION: Do not force the leading edge of the work piece into the blade. The blade will deflect, reducing accuracy of cut, and may break.

• 7. When the cut is complete, move the trailing edge of the work piece beyond the blade guard foot. Turn the switch OFF.

(Diagram description: Figure 21 illustrates freehand cutting. It shows the blade guard foot (1) positioned on the work piece and the height adjustment knob (2).)

ANGLE CUTTING (BEVELING) (Fig. 22)

• 1. Layout or secure design to work piece.
• 2. Move the blade guard foot to the highest position by loosening the height adjustment knob (1). Retighten.
• 3. Tilt the table to the desired angle by loosening the table bevel lock handle (2). Move the table to the proper angle using the degree scale and the pointer (3).
• 4. Tighten the table bevel lock handle (2).
• 5. Loosen the blade guard screw, and tilt the blade guard to the same angle as the table. Retighten the blade guard screw.
• 6. Position the work piece on the right side of the blade. Lower the blade guard foot against the surface by loosening the height adjustment knob. Retighten.
• 7. Follow steps 5 to 7 under Freehand cutting.

(Diagram description: Figure 22 shows angle cutting. It indicates the height adjustment knob (1), table bevel lock handle (2), and degree scale/pointer (3).)

INTERIOR CUTTING (Fig. 23)

• 1. Lay out the design on the work piece. Drill a 1/4" hole in the work piece.
• 2. Remove the blade. See Blade removal and installation.
• 3. Place the work piece on the saw table with the hole in the work piece over the access hole in the table.
• 4. Install a blade through the hole in the work piece.
• 5. Follow steps 3-7, under Freehand cutting.
• 6. When finished making the interior scroll cuts, simply turn the scroll saw OFF. Unplug the saw before removing the blade from the blade holder. Remove the work piece from the table.

(Diagram description: Figure 23 illustrates interior cutting, showing a work piece with a drilled hole placed on the saw table.)

RIP OR STRAIGHT LINE CUTTING (Fig. 24)

• 1. Raise the blade guard foot (1) by loosening the height adjustment knob (2).
• 2. Measure from the tip of the blade to the desired distance. Position the straight edge parallel to the blade at that distance.
• 3. Clamp the straight edge to the table.
• 4. Recheck your measurements using the work piece to be cut and make sure the straight edge is secure.
• 5. Position the work piece against the blade and place the blade guard foot against the top surface of the work piece.
• 6. Secure the blade guard foot in place by tightening the height adjustment knob.
• 7. Remove the work piece from the blade prior to turning the scroll saw ON.

? CAUTION: In order to avoid uncontrollable lifting of the work piece and reduce blade breakage, do not turn the switch on while the work piece is against the blade.

• 8. Position the work piece against the straight edge prior to touching the leading edge of the work piece against the blade.
• 9. Slowly feed the work piece into the blade, guiding the work piece against the straight edge and pressing the work piece down against the table.

? CAUTION: Do not force the leading edge of the work piece into the blade. The blade will deflect, reducing the accuracy of the cut, and may even break.

• 10. When the cut is complete, move the trailing edge of the work piece beyond the blade guard foot. Turn the switch OFF.

(Diagram description: Figure 24 shows rip or straight line cutting. It indicates the blade guard foot (1) and height adjustment knob (2), and a clamped straight edge.)

Maintenance

⚠️ WARNING: Always turn the switch OFF and unplug the power cord from the outlet before maintaining or lubricating the scroll saw.

To ensure that the wood glides smoothly across the work surface, periodically apply a coat of paste wax (sold separately) to the surface of the worktable. If the power cord is worn out or damaged in any way, replace it immediately. Do not attempt to oil the motor bearings or service the motor's internal parts.
