I.  GENERAL SAFETY 
RULES
 WARNING! Read all instructions
Failure to follow all instructions listed 
below may result in electric shock, fire 
and/or serious injury. The term “power 
tool” in all of the warnings listed below 
refers to your main operated (corded) 
power tool and battery operated (cord -
less) power tool.
SAVE THESE INSTRUCTIONS
Work Area Safety
1)  Keep work area clean and well lit.  
Cluttered or dark areas invite acci -
dents.
2)  Do not operate power tools in 
explosive atmospheres, such as in 
the presence of flammable liquids, 
gases or dust. 
Power tools create sparks which may 
ignite the dust or fumes. 3) 
Keep children and bystanders away 
while operating a power tool.  
Distractions can cause you to lose 
control.
Electrical Safety
1)  Power tool plugs must match the 
outlet. Never modify the plug in any 
way. Do not use any adapter plugs 
with earthed (grounded) power 
tools.  
Unmodified plugs and matching 
outlets will reduce risk of electric 
shock.
2)  Avoid body contact with earthed or 
grounded surfaces such as pipes, 
radiators, ranges and refrigerators. 
There is an increased risk of electric 
shock if your body is earthed or 
grounded.
3)  Do not expose power tools to rain 
or wet conditions.  
Water entering a power tool will 
increase the risk of electric shock.
4)  Do not abuse the cord. Never use 
the cord for carrying, pulling or 
unplugging the power tool. Keep 
cord away from heat, oil, sharp 
edges or moving parts.  
Damaged or entangled cords increase 
the risk of electric shock.
5)  When operating a power tool 
outdoors, use an extension cord 
suitable for outdoor use.  
Use of a cord suitable for outdoor use 
reduces the risk of electric shock.
6)  If operating a power tool in a damp 
location is unavoidable, use a 
residual current device (RCD) 
protected supply. 
Use of RCD reduces the risk of elec -
trical shock.
EN

Personal Safety
1) Stay alert, watch what you are 
doing and use common sense 
when operating a power tool. Do 
not use a power tool while you are 
tired or under the influence of 
drugs, alcohol or medication.  
A moment of inattention while operat -
ing power tools may result in personal 
injury.
2)  Use safety equipment. Always wear 
eye protection. 
Safety equipment such as dust mask, 
non-skid safety shoes, hard hat, or 
hearing protection used for appropri -
ate conditions will reduce personal 
injuries.
3)  Avoid accidental starting. Ensure 
the switch is in the off position 
before plugging in.  
Carrying power tools with your finger 
on the switch or plugging in the power 
tools that have the switch on invites 
accidents.
4)  Remove any adjusting key or 
wrench before turning the power 
tool on.  
A wrench or a key left attached to a 
rotating part of the power tool may 
result in personal injury.
5)  Do not overreach. Keep proper 
footing and balance at all times.  
This enables better control of the 
power tool in unexpected situations.
6)  Dress properly. Do not wear loose 
clothing or jewelry. Keep your hair, 
clothing and gloves away from 
moving parts. 
Loose clothes, jewelry or long hair can 
be caught in moving parts.
7)  If devices are provided for the 
connection of dust extraction and 
collection facilities, ensure these 
are connected and properly used.  
Use of these devices can reduce dust 
related hazards.
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 danger -
ous and must be repaired.
3)  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.
4)  Store idle power tools out of the 
reach of children and do not allow 
persons unfamiliar with the power 
tool or these instructions to oper -
ate the power tool.  
Power tools are dangerous in the 
hands of untrained users.
5)  Maintain power tools. Check for 
misalignment or binding of moving 
parts, breakage of parts and any 
other condition that may affect the 
power tools 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 and in the 
manner intended for the particular 
type of power tool, 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.
EN

Battery Tool Use and Care
1) Ensure the switch is in the off 
position before inserting battery 
pack. 
Inserting battery pack into power tools 
that have the switch on invites acci -
dents.
2)  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.
3)  Use power tools only with specifi -
cally designated battery packs. 
Use of any other battery packs may 
create a risk of injury and fire.
4)  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.
5)  Under abusive conditions, liquid 
may be ejected from 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.
Service
1)  Have your power tool serviced by a 
qualified repair person using only 
identical replacement parts. 
This will ensure that the safety of 
power tool is maintained.
II.  SPECIFIC  SAFETY 
RULES
1) Wear ear protection. Exposure to 
noise can cause hearing loss.
2)  Be aware that this tool is always in an 
operating condition, since it does not 
have to be plugged into an electrical 
outlet. 3) 
Hold power tools by insulated gripping 
surfaces when performing an opera -
tion where the cutting tool may 
contact hidden wiring.  
Contact with a “live” wire will make 
exposed metal parts of the tool “live” 
and shock the operator.
4)  If the bit becomes jammed, immedi -
ately turn the trigger switch off to 
prevent an overload which can 
damage the battery pack or motor. 
Use reverse motion to loosen jammed 
bits.
5)  Do NOT operate the Forward/Reverse 
lever when the trigger switch is on. 
The battery will discharge rapidly and 
damage to the unit may occur.
6)  When storing or carrying the tool, set 
the Forward/Reverse lever to the 
center position (switch lock).
7)  Do not strain the tool by holding the 
speed control trigger halfway (speed 
control mode) so that the motor stops. 
The protection circuit will activate and 
may prevent speed control operation. 
If this happens, release the speed 
control trigger and squeeze again for 
normal operation.
8)  Be careful not to get dust inside the 
chuck.
9)  Do not touch the rotating parts to 
avoid injury.
10)  Do not use the tool continuously for a 
long period of time. Stop using the 
tool from time to time to avoid 
temperature rise and heat overload of 
the motor.
11)  Do not drop the tool.
