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 instructions.

 Charging improp-

erly 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.

Cordless 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 inatten-

tion while operating chain saws may cause entan-

glement of your clothing or body with the saw chain.

2. 

Always hold the chain saw with your right 

hand on the top 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 power tool 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 power tool 

"live" and could give the operator an electric shock.

4. 

Wear safety glasses and hearing protection.

 

Further protective equipment for head, hands, 

legs and feet is recommended. Adequate protec-

tive clothing will reduce personal injury by flying 

debris or accidental contact with the saw chain.

5. 

Always keep proper footing.

6. 

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.

7. 

Use extreme caution when cutting brush and sap-

lings.

 The slender material may catch the saw chain 

and be whipped toward you or pull you off balance.

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 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 tool misuse and/or incor-

rect 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.
