Equipment Safety Guidelines

Safety of the operator and bystanders is one of the main concerns in designing and developing equipment. However, every year many accidents occur which could have been avoided by a few seconds of thought and a more careful approach to handling equipment. You, the operator, can avoid many accidents by observing the following precautions in this section. To avoid personal injury or death, study the following precautions and insist those working with you, or for you to follow them.

Safety Training

Safety is a primary concern in the design and manufacture of our products. Unfortunately, our efforts to provide safe equipment can be wiped out by a single careless act of an operator or bystander.

In addition to the design and configuration of equipment, hazard control and accident prevention are dependent upon the awareness, concern, prudence, and proper training of personnel involved in the operation, transport, maintenance, and storage of this equipment.

It has been said, "The best safety feature is an informed, careful operator." We ask you to be that kind of an operator. It is the operator's responsibility to read and understand ALL Safety and Using instructions in the manual and to follow these. Accidents can be avoided.

If this machine is used by any person other than yourself, or is loaned or rented, it is the machine owner's responsibility to make certain that the operator, prior to using:

• Reads and understands the operator's manuals.
• Is instructed in safe and proper use.

Know your controls and how to stop the skid steer tractor and machine quickly in an emergency. Read this manual and the one provided with skid steer tractor.

Train all new personnel and review instructions frequently with existing workers. Be certain only properly trained and physically able person will use the machinery. A person who has not read and understood all using and safety instructions is not qualified to use the machine. An untrained operator exposes himself and bystanders to possible serious injury or death. If the elderly are assisting with the work, their physical limitations need to be recognized and accommodated.

Safety Signs

Always keep safety signs clean and legible.

Replace safety signs that are missing or have become illegible.

Replaced parts that displayed a safety sign should also display the current sign.

Safety signs are available from your authorized Distributor or Dealer Parts Department or the factory.

Operation

Initial Checks

Although there are no operational restrictions on the Wood Chipper when used for the first time, it is recommended that the following mechanical items be checked:

• After operating for 1 hour:
  1. Torque all fasteners and hardware.
  2. Check condition of rotor bearings.
  3. Check the condition and clearance of the twig-breaker, rotor and stationary blades. Adjust or replace as required.
  4. Check for entangled material. Remove all entangled material before resuming work.
  5. Lubricate all grease fittings.
• After operating for 10 hours:
  1. Repeat steps 1 through 5 listed above.
  2. Go to the normal servicing and maintenance schedule as defined in the Maintenance Section.

Pre-Operational Checklist

Efficient and safe operation of the MechMaxx 3 Point Wood Chipper requires that each operator reads and understands the using procedures and all related safety precautions outlined in this section. A pre-operation checklist is provided for the operator. It is important for both the personal safety and maintaining good mechanical condition that this checklist is followed.

Before operating the Wood Chipper and each time thereafter, the following areas should be checked off:

1. Lubricate the machine per the schedule outline in the Maintenance Section.
2. Check the rotor, blades, and twig-breaker. Remove any twine, wire or other material that has become entangled.
3. Check the condition and clearance of the twig-breaker, rotor, and stationary blades. Adjust or replace as required.
4. Check that all bearings turn freely. Replace any that are rough or seized.
5. Make sure that all guards and shields are in place, secured and functioning as designed. Check the condition of the curtain in the feed hopper. It must be in good condition to prevent chips.

Machine Set-Up

Follow this procedure to prepare and setup the machine at the work site:

1. Use the skid steer to position the Wood Chipper at the work site.

IMPORTANT

Position the machine so the prevailing wind/breeze blows the exhaust gases/fumes away from the operator's station.

2. Lower the feed hopper down into its working configuration:

• Remove the nuts on the hopper anchor bolts.
• Unpin the feeder hopper latch.
• Carefully lower the hopper and secure it with the nuts on the anchor bolts.
• Secure the feed hopper latch to the discharge chute with the latch pin.

Trimming the PTO Shaft

A PTO drive line is supplied with the machine. To accompany the variety of 3 point hitch geometry available today, the drive line can be too long for most machines or too short for others. It is very important that the drive line be free to telescope but not to bottom out when going through its working range. If the drive line bottoms out, the bearings on both the machine and tractor PTO shaft will be overloaded and fail in a short time.

Diagram Description: Shows dimensions A (machine dimension) and B (uncut driveline dimension) for calculating the required drive line length. The calculation (B-A) + 1 INCH = C (CUT OFF DIMENSION) is provided.

SHORTENED DRIVELINE

Mounting and Unhooking Tractor

When attaching chipper to a tractor, follow this procedure.

1. Clear the area of bystanders, especially small children.
2. Make sure there is enough room and clearance to safely back up to the chipper.
3. Place the tractor arms in their full sway position.
4. Back up slowly and align the lower link arms to the pins on the machine.
5. Mounting without a Quick Hitch:
1. Align the left lower link with the left chipper pin.
2. Insert the left pin through the ball and install the retainer.
3. Align the right arm to the pin by turning the jack screw on the arm.
4. Insert the right pin through the ball and install the retainer. Return the jack-screw to its starting position.
5. Remove the top pin and install the top link. Use the turnbuckle to align the top link. Insert the pins and install the retainers. Return the turnbuckle to its original length and lock.

Chipping Operation

The Wood Chipper is a strong, rugged machine that is built to a straightforward design which provides consistent chipping of logs up to 4" (102mm).

Always wear personal protective equipment (PPE) whenever operating the machine. This includes but is not limited to protective shoes with slip resistant soles, protective goggles or face shield, heavy gloves, hearing protection and protective clothing.

Do not place metal, bottles, cans, rocks, glass or other solid material into the wood chipper. If something like this gets into the machine, stop the machine immediately for a detailed inspection. Stop engine, remove ignition key and place in your pocket and wait for all moving parts to stop before inspecting or unplugging. Inspect machine for damaged or loosened parts before resuming work.

? DANGER ? Keep hands and feet out of the inlet and discharge openings while the machine is operating to avoid serious personal injury. Turn off the hydraulics, stop the engine, and allow the machine to come to a complete stop before clearing obstructions or making adjustments.

Caution and care should be exercised when feeding material into the feeder. Do not reach into the hopper past the curtain barrier.

• Before beginning to feed the rotor is up to speed.
• Slowly slide the wooden material into the feed hopper and move it into the rotor.
• Do not force the material into the rotor, as the material engages the rotor, the rotor will draw the material in. Use continuous lite pressure to guide in the material.
• Be aware of how much material you feed in, slow down or stop if the rotor begins to slow down.
• Do not reach into the feed hopper further than the curtain to be sure not to contact the blades on the rotor.
• Use a stick or branch to push any piece of material into the rotor that does not move on its own. If the jam persists then stop the engine and wait for the rotor to stop and then clear the jam. Do not take a chance with getting your hand caught in the rotor.
• Ensure your wood chip pile is contained and doesn't affect the immediate work area.

Unplugging

Although the machine is designed to handle a wide variety of material without any problem, occasionally it plugs. When the machine plugs, follow this procedure to unplug:

• Clear the area of bystanders, especially small children.
• Turn off the hydraulics, stop the engine, remove the ignition key and place it in your pocket and wait for all moving parts to stop before unplugging.
• Pull the material out of the feed hopper. Be sure all the material is out, and nothing is jammed or wedged between the input opening and the rotor.
• Pull the material out of the discharge hood. Use a stick to poke loose any material jammed into the discharge hood. Do not allow anything to remain in this area.
• Check that everyone is clear of machine before restarting engine.

Severe Plug

• Clear the area of bystanders, especially small children.
• Turn off the hydraulics, stop the engine, remove the ignition key and place it in your pocket or remove spark plug wire, and wait for all moving parts to stop before unplugging.
• Loosen the feed hopper anchor nuts and raise the feed hopper.
• Remove jammed material from inside the rotor compartment.
• Clean out the discharge area/rotor.
• Open the upper rotary housing and clean out the housing.
• Be sure to turn the rotor by hand to be sure there is nothing jammed between the rotor and stationary blades.
• Close, install and fold down all components opened to unplug. Tighten fasteners to their specified torque.
• Check that everyone is clear of machine before restarting engine.
• Start the engine turn on the hydraulics and resume working.

Maintenance

Blade and Breaker Maintenance

The rotor and ledger blades need to be sharp for the Chipper to perform as expected. Periodic inspection is recommended. Keep the blades sharp to reduce the amount of power required during operation. Watch the sharpness of the blades when processing material with a lot of sand, soil or dirt mixed with it. Reverse or sharpen the blades if the cutting edge becomes dull. Twig breaker should be inspected for gouges or bent.

Rotor Blades

The rotor is equipped with 4 blades spaced evenly to keep the rotor in balance. If one needs to be changed, the one opposite should also be changed. It is recommended that the rotor blades be removed from the rotor when sharpening. Always sharpen the blades at a 45° angle to provide the best cutting effect as it meets the stationary blade. Be sure to tighten the blade mounting bolts to their specified torque when reinstalling the blades to the rotor.

1. Stop the engine, remove the ignition key, and place it in your pocket and wait for all moving parts to stop.
2. Remove the bolt that secures the upper rotor housing, and carefully open the rotor housing.
3. Manually rotate chipper rotor plate so that the blade is fully exposed.
4. Remove the bolts that hold the rotor blade to the rotor, remove the blade.
5. Rotate the blade and reinstall or replace with new or resharpened blade.
6. Ensure the blade is properly oriented, with the leading edge out. The blade is designed to fit into the rotor one way only. See diagram for proper installation.
7. Tighten down bolts as specified in the torque chart.
8. Repeat steps for remaining blades.

Diagram Description: Illustrates rotor blade installation with loading edge and proper orientation. Shows rotor blade, rotor blade bolts, and loading edge.

Routine inspection of the knives for sharpness and wear plate for a sharp edge will ensure that your wood chipper is operating at full efficiency. Using dull knives or a rounded wear plate will decrease performance and cause excessive vibration that will damage the machine and make chipping difficult for the operator.

Ledger Blades

The MechMaxx-BX42S is equipped with a ledger (stationary) blade that acts as a shear for the moving rotor blades. The ledger blade is designed with 4 usable corners. When the corner facing the rotor blade rounds over, remove the blade and reinstall with a different corner facing the rotor blade. It is recommended that the clearance between the rotor and stationary blades be set and maintained at 1/32 to 1/16 " (.76 - 1.52 mm) to obtain the best performance.

1. Turn off the hydraulics, stop the engine, remove the ignition key and place it in your pocket and wait for all moving parts to stop.
2. Remove the 2 bolts that hold the ledger blade to the ledger mount, remove the blade.
3. Rotate the blade and replace or replace with new or re-sharpened blade.
4. Hand tighten the bolts and set the clearance between the ledger and rotor blades at 1/32 - 1/16".
5. Tighten down bolts as specified in the torque chart.

Checking Bolt Torque

The tables shown below give correct torque values for various bolts and cap screws. Tighten all bolts to the torques specified in chart unless otherwise noted. Check tightness of bolts periodically, using bolt torque chart as a guide. Replace hardware with the same strength bolt. Torque figures indicated above are valid for non-greased or non-oiled threads and heads unless otherwise specified. Therefore, do not grease or oil bolts or cap screws unless otherwise specified in this manual. When using locking elements, increase torque values by 5%. * Torque value for bolts and cap screws are identified by their head markings.
