3. General safety 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 and 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

5
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 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 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

6
intended could result in a hazardous situation.
5) 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.
4. Special safety instructions
• Wear ear protectors when impact drilling.
Exposure to noise can cause hearing loss.
• Use auxiliary handle(s), if supplied with the
tool. Loss of control can cause personal injury.
• Hold power tool by insulated gripping
surfaces, when performing an operation where
the cutting accessory may contact hidden
wiring or its own cord. Cutting accessory
contacting a“live”wire may make exposed
metal parts of the power tool“live”and
could give the operator an electric shock.
• Use appropriate detectors to determine if
utility lines are hidden in the work area or
call the local utility company for assistance.
Contact with electric lines can lead to re
and electric shock. Damaging a gas line can
lead to explosion. Penetrating a water line
causes property damage or may cause an
electric shock.
• Switch o the power tool immediately
when the tool insert jams. Be prepared for
high reaction torque that can cause kickback.
The tool insert jams when:
— the power tool is subject to overload or
— it becomes wedged in the workpiece.
• When working with the machine, always
hold it rmly with both hands and provide
for a secure stance. The power tool is guided
more secure with both hands.
• Secure the workpiece. A workpiece clamped
with clamping devices or in a vice is held
more secure than by hand.
• Keep your workplace clean. Blends of materials
are particularly dangerous. Dust from light alloys
can burn or explode.
• Always wait until the machine has come to
a complete stop before placing it down. The
tool insert can jam and lead to loss of control
over the power tool.
• Never use the machine with a damaged cable.
Do not touch the damaged cable and
pull the mains plug when the cable is damaged
while working. Damaged cables increase
the risk of an electric shock.
Products sold in GB only: Your product is tted
with an BS 1363/A approved electric plug with
internal fuse (ASTA approved to BS 1362).
If the plug is not suitable for your socket outlets,
it should be cut o and an appropriate plug tted
in its place by an authorised customer service
agent. The replacement plug should have the
same fuse rating as the original plug.
The severed plug must be disposed of to avoid a
possible shock hazard and should never be
inserted into a mains socket elsewhere.
Products sold in AUS and NZ only: Use a residual
current device (RCD) with a rated residual
current of 30 mA or less.
