Original Instructions
General power tool safety
warnings
WARNING Read all safety
warnings and all
instructions. Failure to follow the
warnings and instructions may
result in electric shock, re and/or
serious injury.
Save all warnings and
instructions for future
reference.
The term "power tool" in the
warnings refers to your mains-
operated (corded) power tool or
battery-operated (cordless) power
tool.
1) Work area safety
a) Keep work area clean and
well lit. Cluttered or dark areas
invite accidents.
b) Do not operate power tools
in explosive atmospheres,
such as in the presence of
ammable liquids, gases or
dust. Power tools create sparks
which may ignite the dust or
fumes.
c) Keep children and
bystanders away while
operating a power tool.
Distractions can cause you to
lose control.
2) Electrical safety
a) 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. Unmodied plugs and
matching outlets will reduce risk
of electric shock.
b) 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.
c) Do not expose power tools
to rain or wet conditions.
Water entering a power tool
will increase the risk of electric
shock.
d) 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.
e) 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.
f) If operating a power tool in a
damp location is unavoidable,

4
EN
use a residual current device
(RCD) protected supply. Use
of an RCD reduces the risk of
electric shock.
3) Personal safety
a) 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 inuence of
drugs, alcohol or medication.
A moment of inattention while
operating power tools may result
in serious personal injury.
b) Use personal protective
equipment. Always wear eye
protection. Protective
equipment such as dust mask,
non-skid safety shoes, hard
hat, or hearing protection used
for appropriate conditions will
reduce personal injuries.
c) Prevent unintentional
starting. Ensure the switch is
in the o󰀨-position before
connecting to power source
and/or battery pack, picking
up or carrying the tool.
Carrying power tools with
your nger on the switch or
energising power tools that have
the switch on invites accidents.
d) 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.
e) Do not overreach. Keep
proper footing and balance at
all times. This enables better
control of the power tool in
unexpected situations.
f) Dress properly. Do not wear
loose clothing or jewellery.
Keep your hair, clothing
and gloves away from moving
parts. Loose clothes, jewellery
or long hair can be caught in
moving parts.
g) If devices are provided
for the connection of dust
extraction and collection
facilities, ensure these are
connected and properly used.
Use of dust collection can
reduce dust-related hazards.
4) Power tool use and care
a) 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.
b) Do not use the power tool
if the switch does not turn it
on and o󰀨. Any power tool that
cannot be controlled with the
switch is dangerous and must

5
EN
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 a󰀨ect 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 dierent from
those intended could result in a
hazardous situation.
5) Battery tool use and care
a) Recharge only with the
charger specied by the
manufacturer. A charger that is
suitable for one type of battery
pack may create a risk of re
when used with another battery
pack.
b) Use power tools only with
specically designated
battery packs. Use of any other
battery packs may create a risk
of injury and re.
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 re.
d) Under abusive conditions,
liquid may be ejected from

6
EN
the battery; avoid contact.If
contact accidentally occurs,
ush with water. If liquid
contacts eyes,additionally
seek medical help. Liquid
ejected from the battery may
cause irritation or burns.
6) Service
a) Have your power tool
serviced by a qualied repair
person using only identical
replacement parts. This will
ensure that the safety of the
power tool is maintained.
Hammer safety warnings
a)Wear ear protectors. Exposure
to noise can cause hearing loss.
b)Use auxiliary handle(s), if
supplied with the tool. Loss
of control can cause personal
injury.
c)Hold power tools by insulated
gripping surfaces, when
performing an operation
where the cutting tool may
contact hidden wiring. Cutting
accessory contacting a “live”
wire may make exposed metal
parts of the power tool “live”
and could give the operatoran
electric shock.
Battery safety warning
a) Do not dismantle, open or
shred secondary cells or
batteries.
b) Keep batteries out of the reach
of children
Battery usage by children
should be supervised. Especially
keep small batteries out of reach
of small children.
c) Do not expose cells or batteries
to heat or re. Avoid storage in
direct sunlight.
d) Do not short-circuit a cell or
a battery. Do not store cells or
batteries haphazardly in a box
or drawer where they may short-
circuit each other or be short-
circuited by other metal objects.
e) Do not subject cells or batteries
to mechanical shock.
f) In the event of a cell leaking, do
not allow the liquid to come in
contact with the skin or eyes. If
contact has been made, wash
the a󰀨ected area with copious
amounts of water and seek
medical advice.
g) Do not use any charger other
than that specically provided
for use with the equipment.
