SAFETY INFORMATIONSAFETY INFORMATION
• Watch out for wires, trees, etc., when raising and moving implement. Make sure all persons
are clear of working area.
• Turning tractor too tight may cause implement to ride up on wheels. This could result in injury
or equipment damage.
• Visually inspect the infeed bin and the ywheel before applying power to ensure that the
chipper head is clear, all the bolts are clear, and the ywheel knives clear the ywheel housing
and the bed knife.
• Bystanders must be at a safe distance from chipper during operation.
• Children should NEVER operate, or be near the chipper during operation.
• Make sure the PTO shaft does not come apart or bottom out during the normal lifting range.
Damage resulting from an improperly sized PTO shaft is not covered under warranty.
• Check the chip pile to see if the knives need to be serviced. Long slivers in the chip pile are
one of the best indicators of dull knives.
• It is NOT recommended to operate the chipper in temperatures below freezing. Hardened
steel (as used on knives) can become brittle in temperatures below freezing and may result in
breakage.
•
Always keep the guards and chip deector installed properly while operating the chipper.
• Never leave the chipper running unattended.
• Do not attempt alterations, repairs, or adjustments while the ywheel is turning. Always
disconnect the PTO, stop the tractor’s motor, and put the keys in your pocket prior to
attempting any alterations, repairs or adjustments.
• Keep hands, feet, clothing and other extremities out of and away from the hopper (infeed
bin) and any power driven parts. Wear snug tting clothing to avoid entanglement with
moving parts.
• No loose clothing should be worn around the chipper. Personal injury can occur if someone
or something turns the ywheel over when the knives are being checked or the cutter bar is
being adjusted. The ywheel has enough residual energy to easily remove ngers.
• Point the discharge chute away from doorways, sidewalks, or any other area where your view
is obstructed. The chute should be pointed downwind when possible. This will keep the chips
from blowing back in the operator’s direction.
A Note to All Users
List of warnings and cautions cannot be all-inclusive. If situations occur that are
not covered by this manual, the operator must apply common sense and operate
this Wood Chipper in a safe manner. If you have any questions, please contact

SAFETY INFORMATIONSAFETY INFORMATION
DANGER
This symbol indicates an imminently hazardous situation which, if not avoided,
will result in death or serious injury. This signal word is limited to the most
extreme situations, typically for machine components that, for functional
purpose, cannot be guarded.
WARNING
This symbol indicates a potentially hazardous situation which, if not avoided,
could result in death or serious injury, and includes hazards that are exposed
when guards are removed. It may also be used to alert against unsafe practices.
CAUTION
This symbol indicates a potentially hazardous situation which, if not avoided,
may result in minor or moderate injury. It may also be used to alert against
unsafe practices.
Safety Alert Symbols
The SAFETY ALERT SYMBOL indicates there is a potential hazard to personal safety
involved and extra safety precaution must be taken. When you see this symbol,
be alert and carefully read the message that follows it. In addition to design and
conguration of equipment, hazard control and accident prevention are dependent
upon the awareness, concern, prudence and proper training of personnel involved in

Use Safety Lights and Devices
• Slow moving tractors, self-propelled equipment, and towed implements can create a
hazard when driven on public roads. They are difcult to see, especially at night.
• Flashing warning lights and turn signals are recommended whenever driving
on public roads. Use lights and devices provided with implement.
Transport Machinery Safely
• Comply with state and local laws.
• Maximum transport speed for any WoodMaxx implement is 20 mph on paved
surface and 10 mph maximum on unpaved surface. Do not exceed. Never travel at
a speed which does not allow adequate control of steering and stopping. Rough
terrain requires a slower speed. Traveling at excessive speed on rough terrain that
causes violent shaking or bouncing of the implement will damage the attachment
point on the implement and/or the tractor. This type of damage is not covered
under warranty.
• Use the following maximum speed - for paved surfaces only:
• 20 mph when weight is less than or equal to the weight of tractor.
• 10 mph when weight is more than the weight of the tractor.
Keep Riders Off Machinery
• Riders obstruct the operator’s view, they could be struck by foreign objects or
thrown from the machine.
• Never allow children to operate equipment.
Practice Safe Maintenance
• Understand procedure before doing work. Use proper tools and equipment.
Refer to Operator’s Manual for additional information.
• Work in a clean dry area.
• Lower the implement to the ground, put tractor in park, turn off engine, and remove
key before performing maintenance.
• Allow implement to cool completely.
• Do not grease or oil implement while it is in operation.

DRIVELINE SAFETYDRIVELINE SAFETY
DRIVELINE SAFETY CHECKLISTDRIVELINE SAFETY CHECKLIST
Agriculture and forestry are recognized as one of the most hazardous of occupations.
Today’s farmer spends long hours in close proximity to increasingly complex and
powerful machinery.
To avoid accidents, everyone from the component supplier and the company who
manufacturers and assembles the machinery, to the dealers and ultimately the
actual user, must keep safety in mind. The checklist below relates to the drive line of
agricultural implements, general safety literature, and the standards published by the
American Society of Agricultural Engineers.
Driveline Specications – The rst step towards safe applications is to specify and
test the driveline so that it operates properly under expected eld conditions.
✔Specify and test the proper size joints and telescoping members based upon
the power required by the implement, speed of rotation, joints angles, shock
loads, and expected life.
✔Test the hitch geometry to prevent the drive line from:
• Extending beyond the recommended maximum length.
• Bottoming out.
• Reaching a position that allows universal joints to lock.
• Exceeding the maximum allowable angle for constant velocity of
the universal joints.
Information concerning these parameters may be found in all driveline
manufacturer’s catalogs.
✔Specify and test telescoping members to allow the lowest possible thrust loads,
considering the expected working conditions.
✔Specify and test torque limiters to control excessive shock loads.
✔Where necessary, specify and test overrunning clutches to prevent inertial loads
from overpowering the tractor.

www.WoodMaxx.com
8
Hazard Reduction – The second step in specifying a safe driveline application is to
strive to eliminate as many hazards as possible
✔On driveline with torque limiting or overrunning devices, specify that
the device be positioned to the end of the driveline by the implement.
✔For implement connections which require bolts or set screws, select
and/or supply hardware which minimizes protrusions. Information concerning
these parameters may be found in all driveline manufacturer’s catalogs.
✔For tractors PTO shaft connections, specify a safety type yoke (twist or
slide collar) to minimize protrusions.
✔Provide a proper clearance zone for the operation of the driveline, to
avoid damaging the shielding components.
Some common areas of interference are:
•
Three point linkage.
• Extended or eye loop hitch pins.
• Hydraulic hoses.
Guarding – For hazards which cannot be eliminated effectively, guarding must be
provided whenever feasible.
The PTO master shield, integral driveline shield, and implement input connection
shield should provide an interactive guarding system.
✔Provide instructions by labels or manuals. The implement should be used only
with the tractor’s PTO master shield in place.
✔Specify and test an integral driveline shield with end cones which overlap, but
not interfere with the PTO master shield or implement input connection shield.
✔Provide an implement input connection shield to interact with the integral
driveline shield to provide guarding of the shaft coupling and any torque
limiting devices installed on the driveline.
✔Check that all routine maintenance of the driveline can be done without
removal of the shields.

DRIVELINE SAFETY CHECKLISTDRIVELINE SAFETY CHECKLIST
Warnings and Instructions – Provide warnings and instructions for hazards associated
with the machine. Provide instructions for proper maintenance and repair.
✔Provide labels on the unit to advise the user of proper hitch dimensions and
maximum safe operating speed.
✔Check that proper danger labels are supplied with the driveline concerning
these parameters may be found in all driveline manufacturer’s catalogs.
✔Provide easy-to-understand instructions for proper driveline operation,
maintenance, and repair in the operator’s manual.
✔Advise against the use of PTO adapters which may defeat the purpose of the
tractor’s master shield and adversely affect the performance of the driveline.
✔Advise the user of locations of genuine original equipment spare parts.
Further information about driveline specications and safety may be obtained from
your driveline supplier and the following ASME standards and engineering practices:
S203 – Rear power take-off for agricultural tractors
S205 – Power take-off denitions and terminology for agricultural tractor
S207 – Operating requirements for tractors and power take-off driven
equipment implements
S318 – Safety for agricultural equipment
S331 – Implement power take-off driveline specications
S333 – Agricultural tractor auxiliary power take-off drives
S350 – Safety alert symbol for agricultural equipment
S441 – Safety signs
S493 – Guarding for agricultural equipment
EP363 – Technical publications for agricultural equipment
Other standards may apply for particular types of implements. All driveline
manufacturers strive to produce a safe product. Drivelines, like most other
components must be used properly, including the use of proper tractor master shields
and implement input connection shields. Please contact us if you have any questions
about your driveline applications.

• Your chipper will need to be set up prior to installation. It arrives in a steel crate that can
be dismantled in minutes.
• The infeed bin and discharge chute are shipped with the unit and are located in the
bottom of the steel crate.
• Visually inspect the infeed bin, and the y wheel before attaching to tractor, and applying
power to ensure that nothing is in the chipper head. If the chip deector or any of the
guards have been removed for shipping, be sure to replace them properly before use.
• The PTO (Driveline) is also shipped with the unit and is located in the bottom of the steel
crate.
• When mounting, keep the chipper as close to the tractor as possible.
• IMPORTANT - Make sure that the PTO shaft is sized properly. See PTO Shaft Sizing
Instructions on page 20 of this manual.

STEP 22 - See PTO Shaft Sizing Instructions on page 20 to size your
PTO shaft to t your tractor. Failure to properly size your PTO shaft
will result in damage to your chipper or tractor.
Damage resulting from improperly sized PTO shaft is not covered under warranty.
• By extending the lower hitch brackets,
you increase the distance between the
tractor and the chipper, which lessens
how much shaft you're required to cut.
• Now the shaft must be sized according
to this measurement. Refer to the “PTO
shaft cutting instructions” starting on
page 20 of this manual to determine if
you must size the shaft .
To adjust the MSED: Remove pin and
move draw arm in or out.
