engine is running or when the engine is hot. Allow engine to cool before refueling.
• If fuel is spilled, do not attempt to start the engine but move the machine away from the area
of spillage and avoid creating any source of ignition until fuel vapors have disappeared.
• Replace all fuel tank and container caps securely.
• Never store the machine or fuel container inside where there is an open flame or spark, such
as a gas hot water heater, space heater, clothes dryer or furnace.
• To reduce fire hazard, keep engine and muer free of debris build-up. Clean up fuel and oil
spillage. Allow unit to cool at least five minutes before storing.
• Never attempt to make any adjustments while the engine is running.
OPERATION
• Never place your hands, feet, or any part of your body in the chipper chute, discharge
opening, or near or under any moving part while the engine is running. Keep clear of the
discharge opening at all times. If it becomes necessary to push material into the chipper
chute, use a small diameter stick, NOT YOUR HANDS.
• Keep your face and body back from chipper chute to avoid accidental bounce back of any
material.
• The machine should only be operated on a level surface. Never operate your unit on a
slippery, wet, muddy, or icy surface.
• Stay alert for hidden hazards or trac. Do not carry passengers.
• If the cutting mechanism strikes a foreign object or if your machine should start making an
unusual noise or vibration, immediately stop the engine, After the machine has come to a
complete stop proceed as follows:
• Remove the spark plug wire(s) and wait for all moving parts to come to a complete stop.
• Inspect for any damage
• Repair or replace any damaged parts before restarting and operating the machine.
• Exercise caution to avoid slipping or falling
• If the machine should start to vibrate abnormally, immediately stop the engine, and wait for
all moving parts to come to a complete stop and inspect for the cause. Vibration is generally
a warning sign of trouble.
• Stop the engine when leaving the operating position, and when making any repairs,
adjustments and inspections. STAY CLEAR OF THE CHIP CHUTE AT ALL TIMES.
• Take all possible precautions as recommended by the manufacturer when leaving the

obstruct clear discharge, cause injury or damage. Wind can also change discharge direction,
so be aware.
• Do not allow an accumulation of processed material to build up in the discharge area as this
will prevent proper discharge and can result in kick-back from the chipper chute.
• Do not allow any part of the engine, especially around the cooling fins and muer, to
become clogged with processed material, leaves, oil, grease or any other combustible
material.
• Do not operate engine if air cleaner or cover over carburetor air-intake is removed, except
