5. Always keep proper footing. Slippery or unstable

surfaces may cause a loss of balance or control of

the chain saw.

6. When cutting a limb that is under tension be

alert for spring back. When the tension in the wood

fibers is released the spring loaded limb may strike

the operator and/or throw the chain saw out of con-

trol.

7. Use extreme caution when cutting brush and

saplings. The slender material may catch the saw

chain and be whipped toward you or pull you off bal-

ance.

8. Carry the chain saw by the front handle with the

chain saw switched off and away from your body.

When transporting or storing the chain saw

always fit the guide bar cover. Proper handling of

the chain saw will reduce the likelihood of accidental

contact with the moving saw chain.

9. Follow instructions for lubricating, chain ten-

sioning and changing accessories. Improperly

tensioned or lubricated chain may either break or

increase the chance for kickback.

10. Keep handles dry, clean, and free from oil and

grease. Greasy, oily handles are slippery causing

loss of control.

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

poses not intended. For example: do not use

chain saw for cutting plastic, masonry or non-

wood building materials. Use of the chain saw for

operations different than intended could result in a

hazardous situation.

12. Causes and operator prevention of kickback:

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 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 con-

trol 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.

Kickback is the result of tool misuse and/or incorrect

operating procedures or conditions and can be

avoided by taking proper precautions as given

below:

– Maintain a firm grip, with thumbs and fingers

encircling the chain saw handles, with both

hands on the saw and position your body and

arm to allow you to resist kickback forces.

Kickback forces can be controlled by the operator,

if proper precautions are taken. Do not let go of

the chain saw.

– Do not overreach and do not cut above shoul-

der height. This helps prevent unintended tip

contact and enables better control of the chain

saw in unexpected situations.

– Only use replacement bars and chains speci-

fied by the manufacturer. Incorrect replacement

bars and 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.

13. Before starting work, check that the chain saw is in

proper working order and that its condition complies

with the safety regulations. Check in particular that:

• The run-down brake is working properly;

• The bar and the sprocket cover are fitted cor-

rectly;

• The chain has been sharpened and tensioned in

accordance with the regulations;

14. Do not start the chain saw with the chain cover

being installed on it. Starting the chain saw with

the chain cover being installed on it may cause the

chain cover to thrown out forward resulting in per-

sonal injury and damage to objects around the oper-

ator.

Top handle chainsaw specific safety warnings

1. This chain saw is designed especially for tree care

and surgery. The chain saw is intended to be used

by properly trained persons only. Observe all instruc-

tions, procedures and recommendations from the

relevant professional organization. Otherwise fatal

accidents may occur. It is recommend that always

using a rising platform (cherry picker, lift) for sawing

in trees. Rappelling techniques are extremely dan-

gerous and require special training. The operators

must be trained to become familiar with safety equip-

ment usage and climbing techniques. Always use

the appropriate belts, ropes and carabiners when

working in trees. Always use restraining equipment

for both the operator and the saw.

2. Perform cleaning and maintenance before storage in

accordance with the instruction manual.

3. Ensure safe positioning of the chain saw during car

transportation to avoid fuel or chain oil leakage,

damage to the tool and personal injury.

4. Do not fill the chain oil near fire. Never smoke when

you fill the chain oil.

5. National regulation may restrict the use of the chain

saw.
