9. 

Always wear protective goggles to protect 
your eyes from injury when using power tools. 
The goggles must comply with ANSI Z87.1 in 
the USA, EN 166 in Europe, or AS/NZS 1336 
in Australia/New Zealand. In Australia/New 
Zealand, it is legally required to wear a face 
shield to protect your face, too.

It is an employer's responsibility to enforce 
the use of appropriate safety protective equip-
ments by the tool operators and by other per-
sons in the immediate working area.

Power tool use and care

1. 

Do not force the power tool. Use the correct 
power tool for your application.

 The correct 

power tool will do the job better and safer at the 

rate for which it was designed.

2. 

Do not use the power tool if the switch does 

not turn it on and off.

 Any power tool that cannot 

be controlled with the switch is dangerous and 
must be repaired.

3. 

Disconnect the plug from the power source 
and/or remove the battery pack, if detachable, 
from the power tool before making any adjust-
ments, changing accessories, or storing power 
tools.

 Such preventive safety measures reduce 

the risk of starting the power tool accidentally.

4. 

Store idle power tools out of the reach of chil-
dren and do not allow persons unfamiliar with 
the power tool or these instructions to operate 
the power tool.

 Power tools are dangerous in the 

hands of untrained users.

5. 

Maintain power tools and accessories. Check for 
misalignment or binding of moving parts, breakage 

of parts and any other condition that may affect the 

power tool’s operation. If damaged, have the power 
tool repaired before use.

 Many accidents are caused 

by poorly maintained power tools.

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 drill safety warnings

Safety instructions for all operations

1. 

Use the auxiliary handle(s).

 Loss of control can 

cause personal injury.

2. 

Hold the 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.

3. 

Always be sure you have a firm footing. Be 

sure no one is below when using the tool in 
high locations.

4. 

Hold the tool firmly.

5. 

Keep hands away from rotating parts.
