9. 

When using the tool, do not wear cloth work 

gloves which may be entangled.

 The entangle-

ment of cloth work gloves in the moving parts may 

result in personal injury.

Battery tool use and care

1. 

Recharge only with the charger specified by 

the manufacturer.

 A charger that is suitable for 

one type of battery pack may create a risk of fire 

when used with another battery pack.

2. 

Use power tools only with specifically desig

-

nated battery packs.

 Use of any other battery 

packs may create a risk of injury and fire.

3. 

When battery pack is not in use, keep it away 

from other metal objects, like paper clips, 

coins, keys, nails, screws or other small metal 

objects, that can make a connection from one 

terminal to another.

 Shorting the battery termi-

nals together may cause burns or a fire.

4. 

Under abusive conditions, liquid may be ejected 

from the battery; avoid contact. If contact acci-

dentally occurs, flush with water. If liquid con

-

tacts eyes, additionally seek medical help.

 Liquid 

ejected from the battery may cause irritation or burns.

5. 

Do not use a battery pack or tool that is dam-

aged or modified.

 Damaged or modified batteries 

may exhibit unpredictable behaviour resulting in 

fire, explosion or risk of injury.

6. 

Do not expose a battery pack or tool to fire or 

excessive temperature.

 Exposure to fire or tem

-

perature above 130 °C may cause explosion.

7. 

Follow all charging instructions and do not 

charge the battery pack or tool outside the 

temperature range specified in the instruc

-

tions.

 Charging improperly or at temperatures 

outside the specified range may damage the 

battery and increase the risk of fire.

Service

1. 

Have your power tool serviced by a qualified repair 

person using only identical replacement parts.

 This 

will ensure that the safety of the power tool is maintained.

2. 

Never service damaged battery packs.

 Service 

of battery packs should only be performed by the 

manufacturer or authorized service providers.

3. 

Follow instruction for lubricating and chang-

ing accessories.

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 

reversed hand configuration increases the risk of 

personal injury and should never be done.

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 

will reduce personal injury from flying debris or 

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 

result in serious personal injury.

6. 

Always keep proper footing and operate the 

chain saw only when standing on fixed, secure 

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 

wood fibres is released, the spring loaded limb 

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 

chain and be whipped toward you or pull you off 

balance.

9. 

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.

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 

chain saw for operations different than intended 

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.

 Serious injury could occur to the operator or 

bystanders while felling a tree.

13. 

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 

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.

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:
