General safety rules

Warning! Read all instructions. Failure to follow all instructions
listed below may result in electric shock, fi re and/or serious injury.
The term "power tool" in all of the warnings listed below refers to
your mains operated (corded) power tool or battery operated
(cordless) power tool.
SAVE THESE INSTRUCTIONS.
1 Work area
a Keep work area clean and well lit.
Cluttered and dark areas invite accidents.
b Do not operate power tools in explosive atmospheres, such as
in the presence of fl 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.
Unmodifi 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.

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 infl uence of drugs, alcohol or medication.
A moment of inattention while operating power tools may result in
serious personal injury.
b Use safety equipment. Always wear eye protection.
Safety equipment such as dust mask, non-skid safety shoes, hard
hat, or hearing protection used for appropriate conditions will reduce
personal injuries.
c Avoid accidental starting. Ensure the switch is in the off
position before plugging in.
Carrying power tools with your fi nger on the switch or plugging in
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 these devices 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
off.
Any power tool that cannot be controlled with the switch is dangerous
and must be repaired.
c Disconnect the plug from the power source 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 tools 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 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.
5 Service
a Have your power tool serviced by a qualifi ed repair person
using only identical replacement parts.
This will ensure that the safety of the power tool is maintained.
