POTENTIAL DANGERS

25

Burns, Fire

    WARNING!

Gasoline is extremely
flammable. Use caution
when handling gasoline or
fuel.

Taking the following precautions will lessen the chance
of fire:

•

Check your saw for fuel leakage periodically: fuel
tank, cap, hose, etc. Repair as soon as any parts
seem to be in poor condition or as soon as a leakage
is noticed.

•

Fill the chain saw fuel tank in well-ventilated areas on
a bare surface at least 10 feet (3 m) away from the
cutting area.

•

Be sure the muffler is undamaged and securely
fastened.

•

Keep the spark plug cover and ignition wire in good
condition. Replace if worn or damaged.

•

Do not smoke or allow any source of heat near
gasoline or fuel.

•

Allow a hot saw to cool before refueling.

•

When refueling, open fuel cap slowly to release any
pressure.

•

If fuel is spilled on the engine, wipe it off or let it
evaporate before starting the saw.

•

Clear flammable material away before cutting and do
not leave a hot saw on dry litter or combustible
material.

•

Do not use a saw that is backfiring or otherwise not
running properly. Have it repaired.

•

Keep a fire extinguisher and shovel handy.

•

Do not use a damaged muffler or a muffler without a
spark arrestor screen if required in your area.

Touching a hot muffler causes burns. A hot muffler or
hot exhaust gases can start a fire in combustible
material. Spills or improper handling of fuel or gasoline
can cause fire or explosion.

Some states in the USA require testing and approval of
muffler design and exhaust gas temperatures. Do not
modify your muffler, as it may be unlawful to operate a
modified saw and you might start a forest fire. Help
prevent wildfires.

Fuel Spillage

# 

WARNING!

If fuel spillage has occurred, the saw may catch fire if
you attempt to start it. This may cause serious burn
injuries.

Fuel spillage may occur because of fuel tank over-filling.
If fuel spillage has occurred, do not attempt to start your
chain saw. The excessive fuel may catch fire. The fuel
may be ignited by sparks from many sources such as the
muffler, defective wiring, the bar and chain etc.
Tilt the saw over in both directions to allow spilled fuel to
run off. Remove the cylinder cover. Remove any build-up
of saw dust. If such build-up has been soaked in fuel, it
will take much longer for the fuel to evaporate. Let saw
sit for at least 15 minutes to allow the fuel to evaporate;
longer if the temperature is below 50°F (10°C). Move the
saw at least 10 feet (3 m) away from the spot where you
refueled the saw to avoid that any remaining fuel on the
ground catches fire.
