equipment. Local regulations may restrict the age of the
operator.
• All operators and mechanics should be trained. The owner is
responsible for training the users.
• Keep the operator zone and adjacent area clear for safe,
secure footing.
Towing
Check with your local county or state safety towing
regulations, in addition to meeting Department of
Transportation (DOT) Safety Towing Regulations, before
towing the machine.
• In order to reduce the possibility of an accident while
transporting the machine on public roads, ALWAYS make
sure the towing vehicle is mechanically sound and in good
operating condition.
• ALWAYS shutdown engine before transporting the
machine.
• ALWAYS inspect the hitch and coupling for wear. NEVER

vehicle that has a hitch designed for towing. Do not attach
towed equipment except at the hitch point.
Before towing check to make certain your machine is
correctly and securely attached to the towing vehicle.

drugs, or medication.
• Never allow anyone to operate this machine without proper
instruction.
• Always operate this machine with all safety equipment in
place and working.
• Do not change the engine governor setting or over speed the
engine.
• Never place your hands, feet, or any part of your body in the
hopper, discharge chute opening, or near or under any moving
part while the machine is running.
• Keep area of discharge clear of people, animals, buildings,
glass, or anything else that will obstruct clear discharge, cause
injury, or damage. Wind can also change discharge directi o n ,
so be aware. If it becomes necessary to push material into the
hopper, use a small diameter stick, not your hands.
• Never use the machine with the hopper or discharge chute
removed.
• Always operate the machine from along side the hopper.
Never pass or stand on the discharge side of the machine
when the engine is running or the flywheel is turning.
• Clear the area of objects such as wire, rope, etc. Inserting
these objects into the hopper could damage the flywheel
and/or cause injury.
• Keep your face and body back from the hopper to avoid
accidental bounce back of any material.
• If you hear or see material being kicked back against the
rubber flap shut the feeder chute door until the debris has
passed.
• When feeding material into the hopper, be extremely careful
that pieces of metal, rocks or other foreign objects are not
included. Personal injury or damage to the machine could
result.
• Whenever you leave the operating position or if you have to
remove processed material, leaves, or debris from the
machine, always shut off the engine and wait five minutes to
make certain the flywheel and all moving parts have come to
a complete stop and cool. Remove the key, disconnect the
spark plug wires and keep the wire away from the spark plug
to prevent accidental starting before adjusting the machine.
• If the cutting mechanism strikes a foreign object or if your
machine should start making an unusual noise or vibration,
stop the engine and wait five minutes for all moving parts to
come to a complete stop and cool. Vibration is generally a
warning of trouble. Disconnect the spark plug wires and
inspect for clogging or damage. Clean and repair and/or
replace damaged parts.
• Do not touch parts that may be hot from operation. Allow
them to cool before attempting to maintain, adjust, or service.
• Never run an engine in an enclosed area.
• Never move this machine while the engine is running.
• Lightning can cause severe injury or death. If lightning is
seen or thunder is heard in the area, do not operate the
machine; seek shelter.
• Do not touch the engine or muffler while the engine
is running or soon after it is stopped. These areas
could be hot enough to cause a burn.
Maintenance and Storage
• Stop the engine and remove the spark plug wires before
making any repairs. Wait for all movement to stop before
adjusting, cleaning, or repairing.
• Inspect the machine before each use. Make sure all nuts,
bolts, screws, hydraulic fittings, hose clamps, are securely
tightened.
• Clean debris from the muffler and engine to help prevent
fires. Clean up oil or fuel spillage.
• Let the engine cool before storing and do not store near
flame.
• Do not store fuel near flames or drain indoors.
• Park the machine on level ground. Never allow untrained
personnel to service the machine.
