2. CHILDREN

Tragic accidents can occur if the operator is not alert to the
presence of small children. Children are often attracted to
the chipper-shredder and the chipping and shredding
activity. Never assume that children will remain where you

last saw them.

Keep children out of the work area and under the
watchful eye of a responsible adult other than the
operator.

Be alert and turn the unit off if a child enters the area.

• Never allow children under the age of 16 to operate
the chipper-shredder.

3. SERVICE

° Use extreme care in handling gasoline and other

fuels. They are extremely flammable and the vapors
are explosive.

Store fuel and oil in approved containers, away from
heat and open flame, and out of the reach of

children. Check and add fuel before starting the
engine. Never remove gas cap or add fuel while the
engine is running. Allow engine to cool at least two

minutes before refueling.

• Replace gasoline cap securely and wipe off any
spilled gasoline before starting the engine as it may

cause a fire or explosion.

• Extinguish all cigarettes, cigars, pipes and other
sources of ignition.

• Never refuel unit indoors because flammable vapors
will accumulate in the area.

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.

Never run your machine in an enclosed area as the
exhaust from the engine contains carbon monoxide,
which is an odorless, tasteless and deadly poisonous

gas.

To reduce fire hazard, keep engine and muffler free
of leaves, grass, and other debris build-up. Clean up
fuel and oil spillage. Allow unit to cool at least 5
minutes before storing.

Before cleaning, repairing, or inspecting, make
certain the impeller and all moving parts have
stopped. Disconnect the spark plug wire and keep
wire away from spark plug to prevent accidental
starting. Do not use flammable solutions to clean air

filter.

O

Check the blade and engine mounting screws at
frequent intervals for proper tightness. Also visually
inspect blades for wear and/or damage (e.g, bent,
cracked). Replace with blades which meet original
equipment specifications.

Keep all nuts, bolts, and screws tight to be sure the
equipment is in safe working condition.

Never tamper with safety devices. Check their proper
operation regularly.

After striking a foreign object, immediately stop the
engine, disconnect the spark plug wire from the
spark plug, and thoroughly inspect the unit for any
damage. Repair damage before starting and
operating unit.

Do not alter or tamper with the engine's governor

setting. The governor controls the maximum safe
operating speed of the engine. Over-speeding the
engine is dangerous and will cause damage to the
engine and to other moving parts of the machine.

WARNING - YOUR RESPONSIBILITY: Restrict the use of this power machine to persons who read,

understand and follow the wa.n_ngs and nstruct_ons n this manual and on the machine.
