Some dust created by power
sanding, sawing, grinding, drilling,
and other construction activities
contains chemicals known to
cause cancer, birth defects or
other reproductive harm. Some
examples of these chemicals are:
• Lead from lead-based paints,
• Crystalline silica from bricks
and cement and other masonry
products, and
• Arsenic and chromium from
chemically treated lumber.
Your risk from these exposures
varies, depending on how
often you do this type of work.
To reduce your exposure to
these chemicals: work in a well
ventilated area, and work with
approved safety equipment, such
as those dust masks that are
specially designed to lter out
microscopic particles.

General power tool safety
warnings
WARNING Read all safety
warnings, instructions,
illustrations and specications
provided with this power tool.
Failure to follow all instructions
listed below 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. Unmodied plugs and
matching outlets will reduce risk
of electric shock.
b) Avoid body contact with
4
EN
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,
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 inuence 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 a 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.
5
EN
f) Dress properly. Do not wear
loose clothing or jewellery.
Keep your hair and clothing
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
be repaired.
c) Disconnect the plug from
the power source and/or
remove the battery pack, if
detachable, 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 and
accessories. Check for
misalignment or binding of
moving parts, breakage of
parts and any other condition
that may aect 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 dierent from
those intended could result in a

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.
