Safety precautions for chain saw
(ANSI B 175.1-2000 Annex C)
Kickback safety precautions
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.
Other safety precautions
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
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
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
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.

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
the guide bar up and back towards the
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.
WARNING! Do not operate a chain saw
with one hand! Serious injury to the
operator, helpers, bystanders or any
combination of these persons may result
from one-handed operation. A chain saw
is intended for two-handed use.
