Annex C_
Kickback
safety precautions
,_
WARNING!
Kickback
may occur when the
nose or tip of the guide
bar touches
an
object, or when the wood closes
in and
pinches
the saw chain
in the cut,
Tip contact in some cases
may cause a
lightning fast reverse reaction, kicking
_he guide
bar up and back towards the
operator.
Pinching
the saw chain along the top of
the guide
bar may push the guide
bar
rapidly
back towards the operator.
Either
of these reactions
may cause you
to lose control of the saw which could
result
in serious
personal
injury,
Do not rely exclusively
upon the safety
devices built into your saw. As a chain
saw user, you should
take several
steps
to keep your cutting
jobs free from
accident
or injury.
With a basic understanding
of kickback, you can reduce
or eliminate the element of surprise. Sudden surprise
contributes
to accidents.
Keep a good firm grip on the saw with both hands, the
right hand on the rear handle, and the left hand on the
front handle, when the engine is running. Use a firm grip
with thumbs and fingers encircling the chain saw handles.
A firm grip will help you reduce kickback and maintain
control of the saw. Don't let go.
Make sure that the area in which you are cutting is free
from obstacles. Do not let the nose of the guide bar
contact a log, branch, or any other obstacle which could
be hit while you are operating the saw.
Cut at high engine speeds.
Do not overreach
or cut above shoulder height.
Follow manufacturer's
sharpening
and maintenance
instructions
for the saw chain.
Only use replacement
bars and chains specified
by the
manufacturer
or the equivalent.

Do not operate a chain saw when you are fatigued.
Use safety footwear;
snug-fitting
clothing, protective
gloves, and eye, hearing and head protection
devices.
Use caution when handling fuel. Move the chain saw at
least 10 feet (3 m) from the fueling point before starting
the engine.
Do not allow other persons to be near the chain saw when
starting or cutting with the chain saw. Keep bystanders
and animals out of the work area.
Do not start cutting until you have a clear work area,
secure footing and a planned retreat path from the falling
tree.
Keep all parts of your body away from the saw chain when
the engine is running.
Before you start the engine, make sure that the saw chain
is not contacting
anything.
Carry the chain saw with the engine stopped, the guide
bar and saw chain to the rear, and the muffler away from
your body.
Do not operate a chain saw that is damaged,
improperly
adjusted, or not completely
and securely assembled.
Be
sure that the saw chain stops moving when the throttle
control trigger is released.
Shut off the engine before setting the chain saw down.
Use extreme caution when cutting small size brush and
saplings because
slender material may catch the saw
chain and be whipped toward you or pull you off balance.
When cutting a limb that is under tension be alert for
springback so that you will not be struck when the tension
in the wood fibers is released.
Keep handles dry, clean and free of oil or fuel mixture.
Operate the chain saw only in well-ventilated
areas.
Do not operate a chain saw in a tree unless you have
been specifically
trained to do so.
Do not operate a chain saw above shoulder height.
All chain saw service,
other than the items listed in the
operator's/owner's
safety and maintenance
instructions,
should be performed
by competent
chain saw service
personnel. (For example,
if improper tools are used to
remove the flywheel or if an improper tool is used to hold
the flywheel
in order to remove the clutch, structural
damage to the flywheel
could occur and subsequently
cause the flywheel to burst.)
When transporting
your chain saw, use the appropriate
guide bar guard.

Annex is intended primarily for the consumer or
occasional
