that cannot be controlled with the switch is 
dangerous and must be repaired.

c)  Disconnect the plug from the power source 

and/or the battery pack from the power tool 
before making any adjustments, changing 
accessories, or storing power tools. 

Such 

preventive safety measures reduce the risk of 
starting the power tool accidentally. 

d)  Store idle power tools out of the reach of 

children 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.

 

e)  Maintain power tools. 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. 

f)  Keep cutting tools sharp and clean. 

Properly 

maintained cutting tools with sharp cutting 
edges are less likely to bind and are easier to 
control. 

g)  Use the power tool, accessories and tool bits 

etc. in accordance with these instructions, 
taking 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.

 

h)  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.

5)  Battery tool use and care
a)  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.

b)  Use power tools only with specifically 

designated battery packs. 

Use of any other 

battery packs may create a risk of injury and fire.

c) 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 terminals together may cause burns or 
a fire.

d)  Under abusive conditions, liquid may be 

ejected from the battery; avoid contact. If 
contact accidentally occurs, flush with water. 

If liquid contacts eyes, additionally seek 
medical help. 

Liquid ejected from the battery 

may cause irritation or burns.

e)  Do not use a battery pack or tool that is 

damaged or modified.

 

Damaged or modified 

batteries may exhibit unpredictable behaviour 
resulting in fire, explosion or risk of injury.

 

f)  Do not expose a battery pack or tool to fire 

or excessive temperature.

 

Exposure to fire or 

temperature above 130 °C may cause explosion

g)  Follow all charging instructions and do 

not charge the battery pack or tool outside 
the temperature range specified in the 
instructions. 

Charging improperly or at 

temperatures outside the specified range may 
damage the battery and increase the risk of fire.

6) Service
a)  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.

b)  Never service damaged battery packs.

 

Service of battery packs should only be 
performed by the manufacturer or authorized 
service providers.

SAFETY WARNING

1.  Hold power tool by insulated gripping 

surfaces, when performing an operation 
where the fastener may contact hidden 
wiring. Fasteners contacting a “live” wire 
may make exposed metal parts of the power 
tool “live” and could give the operator an 
electric shock.

SAFETY WARNINGS FOR 

BATTERY PACK

a)  Do not dismantle, open or shred cells or 

battery pack. 

b)  Do not short-circuit a battery pack. Do not 

store battery packs haphazardly in a box or 
drawer where they may short-circuit each 
other or be short-circuited by conductive 
materials. 

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
