Save all warnings and instruc-

tions for future reference.

The term "power tool" in the warnings refers to your

mains-operated (corded) power tool or battery-operated

(cordless) power tool.

General chain saw safety warnings

1. Keep all parts of the body away from the saw

chain when the chain saw is operating. Before

you start the chain saw, make sure the saw

chain is not contacting anything. A moment of

inattention while operating chain saws may cause

entanglement of your clothing or body with the

saw chain.

2. Always hold the chain saw with your right

hand on the rear handle and your left hand on

the front handle. Holding the chain saw with a



3. Hold the chain saw by insulated gripping sur-

faces only, because the saw chain may contact

hidden wiring. Saw chains contacting a "live"

wire may make exposed metal parts of the chain

saw "live" and could give the operator an electric

shock.

4. Wear eye protection. Further protective equip-

ment for hearing, head, hands, legs and feet is

recommended. Adequate protective equipment



accidental contact with the saw chain.

5. Do not operate a chain saw in a tree, on a lad-

der, from a rooftop, or any unstable support.

Operation of a chain saw in this manner could



6. Always keep proper footing and operate the



and level surface. Slippery or unstable surfaces

may cause a loss of balance or control of the

chain saw.

7. When cutting a limb that is under tension, be

alert for spring back. When the tension in the



may strike the operator and/or throw the chain

saw out of control.

8. Use extreme caution when cutting brush and

saplings. The slender material may catch the saw



body. When transporting or storing the chain

 Proper

handling of the chain saw will reduce the likelihood

of accidental contact with the moving saw chain.

10. Follow instructions for lubricating, chain

tensioning and changing the bar and chain.

Improperly tensioned or lubricated chain may

either break or increase the chance for kickback.

11. Cut wood only. Do not use chain saw for pur-

poses not intended. For example: do not use

chain saw for cutting metal, plastic, masonry

or non-wood building materials. Use of the



could result in a hazardous situation.

12. Do not attempt to fell a tree until you have an

understanding of the risks and how to avoid

them.

bystanders while felling a tree.

13. Causes and operator prevention of kickback:

Kickback may occur when the nose or tip of the



closes in and pinches the saw chain in the cut.

Tip contact in some cases may cause a sudden

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

Kickback is the result of chain saw misuse and/or

incorrect operating procedures or conditions and

can be avoided by taking proper precautions as

given below:

with both hands on the saw and position

your body and arm to allow you to resist

kickback forces. Kickback forces can be con-

trolled by the operator, if proper precautions

are taken. Do not let go of the chain saw.

• Do not overreach and do not cut above

shoulder height. This helps prevent unin-

tended tip contact and enables better control

of the chain saw in unexpected situations.

• Only use replacement guide bars and saw



Incorrect replacement guide bars and saw

chains may cause chain breakage and/or

kickback.

• Follow the manufacturer’s sharpening

and maintenance instructions for the saw

chain. Decreasing the depth gauge height

can lead to increased kickback.

14. Follow all instructions when clearing jammed

material, storing or servicing the chain saw.

when heavy pressure is applied;

• The cutting edge is obviously damaged;

• The saw pulls to the left or right in the wood.

(caused by uneven sharpening of the saw chain or

damage to one side only)

Sharpen the saw chain frequently but a little each time.
