Safe Handling of Gasoline:
4.
To avoid personal injury or property damage use extreme care
in handling gasoline. Gasoline is extremely flammable and the
vapors are explosive. Serious personal injury can occur when
gasoline is spilled on yourself or your clothes which can ignite.
Wash your skin and change clothes immediately.
1.
Use only an approved gasoline container.
2.
Never fill containers inside a vehicle or on a truck or trailer
bed with a plastic liner. Always place containers on the
ground away from your vehicle before filling.
3.
When practical, remove gas-powered equipment from
the truck or trailer and refuel it on the ground. If this is not
possible, then refuel such equipment on a trailer with a
portable container, rather than from a gasoline dispenser
nozzle.
4.
Keep the nozzle in contact with the rim of the fuel tank or
container opening at all times until fueling is complete. Do
not use a nozzle lock-open device.
5.
Extinguish all cigarettes, cigars, pipes and other sources of
ignition.
6.
Never fuel machine indoors.
7.
Never remove gas cap or add fuel while the engine is hot or
running. Allow engine to cool at least two minutes before
refueling.
8.
Never over fill fuel tank. Fill tank to no more than ½
inch below bottom of filler neck to allow space for fuel
expansion.
9.
Replace gasoline cap and tighten securely.
10.
If gasoline is spilled, wipe it off the engine and equipment.
Move unit to another area. Wait 5 minutes before starting
the engine.
11.
To reduce fire hazards, keep machine free of grass, leaves,
or other debris build-up. Clean up oil or fuel spillage and
remove any fuel soaked debris.
12. Never store the machine or fuel container inside where
there is an open flame, spark or pilot light as on a water
heater, space heater, furnace, clothes dryer or other gas
appliances.

a.
Inspect for damage.
b.
Repair or replace any damaged parts.
c.
Check for any loose parts and tighten to assure
continued safe operation.
5.
Do not allow an accumulation of processed material to
build up in the discharge area. This can prevent proper
discharge and result in kickback of material through the
feed opening.
6.
Do not attempt to shred or chip material larger than
specified on the machine or in this manual. Personal injury
or machine damage could result.
7.
Never attempt to unclog either the feed intake or discharge
opening while the engine is running. Shut the engine off,

alteration, vandalism, theft, fire, water, or damage because of other
peril or natural disaster. Damage resulting from the installation or use
of any part, accessory or attachment not approved by MTD for use
with the product(s) covered by this manual will void your warranty as
