SAFETY PRECAUTIONS FOR CHAIN SAW USERS
(ANSI B175.1-2012 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 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.

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

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.

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.
