6. 

Keep cutting tools sharp and clean.

 Properly 

maintained cutting tools with sharp cutting edges 

are less likely to bind and are easier to control.

7. 

Use the power tool, accessories and tool bits 

etc. in accordance with these instructions, tak

-

ing into account the working conditions and 

the work to be performed.

 Use of the power tool 

for operations different from those intended could 

result in a hazardous situation.

8. 

Keep handles and grasping surfaces dry, 

clean and free from oil and grease.

 Slippery 

handles and grasping surfaces do not allow for 

safe handling and control of the tool in unexpected 

situations.

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 con

-

tact accidentally occurs, flush with water. If 

liquid contacts 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.

CORDLESS ROTARY HAMMER 

SAFETY WARNINGS

1. 

Wear ear protectors.

 Exposure to noise can 

cause hearing loss.

2. 

Use auxiliary handle(s), if supplied with the 

tool.

 Loss of control can cause personal injury.

3. 

Hold power tool by insulated gripping sur-

faces, when performing an operation where the 

cutting accessory may contact hidden wiring.

 

Cutting accessory contacting a "live" wire may 

make exposed metal parts of the power tool "live" 

and could give the operator an electric shock.

4. 

Wear a hard hat (safety helmet), safety glasses and/

or face shield. Ordinary eye or sun glasses are NOT 

safety glasses. It is also highly recommended that 

you wear a dust mask and thickly padded gloves.

5. 

Be sure the bit is secured in place before operation.

6. 

Under normal operation, the tool is designed to 

produce vibration. The screws can come loose 

easily, causing a breakdown or accident. Check 

tightness of screws carefully before operation.

7. 

In cold weather or when the tool has not been 

used for a long time, let the tool warm up for 

a while by operating it under no load. This 

will loosen up the lubrication. Without proper 

warm-up, hammering operation is difficult.

8. 

Always be sure you have a firm footing. Be sure no 

one is below when using the tool in high locations.

9. 

Hold the tool firmly with both hands.

10. 

Keep hands away from moving parts.

11. 

Do not leave the tool running. Operate the tool 

only when hand-held.

12. 

Do not point the tool at any one in the area 

when operating. The bit could fly out and 

injure someone seriously.

13. 

Do not touch the bit, parts close to the bit, or 

workpiece immediately after operation; they 

may be extremely hot and could burn your skin.

14. 

Some material contains chemicals which may 

be toxic. Take caution to prevent dust inhala

-

tion and skin contact. Follow material supplier 

safety data.

SAVE THESE INSTRUCTIONS.

WARNING:

 

DO NOT let comfort or familiarity 

with product (gained from repeated use) replace 

strict adherence to safety rules for the subject 

product. MISUSE or failure to follow the safety 

rules stated in this instruction manual may cause 

serious personal injury.
