AMERICAN STANDARD SAFETY PRECAUTIONS

Safety precautions for chain saw 
users

(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 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.

Note: This Annex is intended primarily for the consumer or 
occasional user.

!

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 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.

!

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.
