Saw Maintenance and Kickback Safety

Follow maintenance instructions in this manual. Proper cleaning of saw and chain and guide bar maintenance can reduce chances of kickback. Inspect and maintain saw after each use. This will increase the service life of your saw. Note: Even with proper sharpening, risk of kickback can increase with each sharpening.

PUSHBACK AND PULL-IN

PUSHBACK AND PULL-IN WARNING: Avoid pushback and pull-in. These hazards can cause you to lose control of chain saw. Pushback or pull-in can cause severe injury.

Cause Of Pushback and Pull-In

Pushback may occur while cutting with top of guide bar. Pushback will force saw back towards you. Pull-in may occur while cut- ting with bottom of guide bar. Pull-in will force saw in towards wood you are cutting. These hazards can occur if chain is pinched, caught, or contacts a non-wood object.

The following steps will reduce the risk of pushback or pull-in:

Use both hands to grip saw while saw is running. Use firm grip. Thumbs and fingers must wrap around saw handles.

Do not overreach or cut above shoulder height.

Keep solid footing and balance.

Stand slightly to left side of saw. This keeps your body from being in direct line with chain.

Have saw running at full speed before starting a cut.

When cutting, make sure spike of saw is against wood (pull-in only). See Prod- uct Identification, page 6, to locate spike.

Never try cutting through two logs at same time. Only cut one log at a time.

Watch for shifting of log or other forces that may pinch chain.

Use extreme caution when re-entering a previous cut.

Do not twist saw when removing guide bar from undercut.

Use wedges made of plastic, wood, or light alloy (never steel or iron) to hold cut open.

CHAIN SAW OPERATION

1.Stay alert. Use common sense while operating chain saw.

2.Keep work area clean. Cluttered areas invite injuries.

3.Be aware of extension cord while op- erating chain saw. Be careful not to trip over cord.

4.Keep children, animals, and bystand- ers away from chain saw and extension cord. Only chain saw user should be in work area.

5.Do not cut down a tree unless you are trained or have expert help.

6.If two or more persons perform buck- ing and felling operations at the same time, provide plenty of distance between operations. Provide distance of at least twice the height of tree being felled.

7.Secure wood you are cutting by using clamps or chocks.

8.Grip chain saw firmly with both hands. Never operate chain saw with one hand. Never use hand guard as handle.

9.Keep finger off trigger until ready to make cut.

10.Before starting chain saw, make sure chain is not touching anything.

11.Avoid body contact with grounded ob- jects such as pipes, wire fences, and metal posts.

12.Keep all parts of body away from chain when saw is running.

13.Do not force chain saw while cutting. Apply light pressure.

14.Cut small brush and saplings with ex- treme care. Slender material may catch in chain and be whipped toward you. This could also pull you off balance.

15.When cutting limb or tree trunk that is under tension, use extreme caution. Be alert for wood springing back. When wood tension is released, limb could spring back and strike operator caus- ing severe injury or death.

16.Do not activate the chain brake to stop saw. Always release trigger to stop saw.

17.Carry chain saw from one place to an- other

with chain saw unplugged

by holding front handle (never use front hand guard as handle)

with finger off trigger

with guide bar and chain to rear

with scabbard in place

Cause Of Pushback and Pull-In WARNING: Some dust cre- ated by power sanding, sawing, grinding, drilling, and other con- struction activities contains chemicals known (to the state of California) to cause cancer, birth defects, or other reproductive harm. Some examples of these chemicals are:

lead from lead-based paints

crystalline silica from bricks and cement and other masonry products
arsenic and chromium from chemically-treated lumber

Your risk from these exposures varies, depending on how often you do this type of work. To re- duce your exposure to these chemicals: work in a well venti- lated area, and work with ap- proved safety equipment, such as those dust masks that are spe- cially designed to filter out mi- croscopic particles.
