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, fire
and/or serious injury.
Save all warnings and instructions for
future reference. The term "power tool" in
the warnings refers to your electric (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
flammable 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 grounded power tools.
Unmodified plugs and matching outlets will
reduce risk of electric shock.
b) Avoid body contact with grounded surfaces,
such as pipes, radiators, ranges and
refrigerators.There is an increased risk of electric
shock if your body is 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 influence 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 off position before connecting to
power source and/or battery pack, picking up or
carrying the tool. Carrying power tools with your
finger 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.

AG820 02
GENERAL POWER TOOL SAFETY WARNINGS
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 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
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 affect 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 different from those intended could
result in a hazardous situation.
5. Service
a) Have your power tool serviced by a qualified
repair person using only identical replacement
parts. This will ensure that the safety of the power
tool is maintained.
b) If the replacement of the supply cord is
necessary, this has to be done by the
manufacturer or its agent in order to avoid a
safety hazard.

GENERAL POWER TOOL SAFETY WARNINGS
6. Additional Safety and working
Instructions
a) Dust from materials such as lead-containing
coatings, some wood types, minerals and
metals can be harmful to one’s health and
cause allergic reactions, leading to respiratory
infections and/or cancer. Materials containing
asbestos may only be worked by specialists.
Observe the relevant regulations in your country
for the materials to be worked.
b) Prevent dust accumulation at the workplace.
Dust can easily ignite.
7. SAFETY WARNINGS for Grinding
Operating
a) Use only wheel types that are recommended
for your power tooland the specific guard
designed for theselected wheel. Wheels for
which thepower tool was notdesigned cannot
be adequately guarded and are unsafe.
b) The grinding surface ofcentre depressed
wheels must be mounted below the plane of the
guard lip.An improperly mounted wheel that
projects through the plane of the guard lip
cannot beadequately protected.
c) The guard must be securely attached to the
power tool and positioned for maximum safety,
so theleast amount ofwheel isexposed
towards the operator. The guard helps to
protect the operator from broken wheel
fragments and accidental contact with the
wheel and sparks that could ignite clothing.
d) Wheels must be used only for recommended
applications. For example: donot grind with the
side of the wheel. Abrasive cut-off wheels are
intended for peripheral grinding, side forces
applied to these wheels may cause themto
shatter .
e) Always useundamaged wheel flanges that are of
correct size and shape for your selected wheel.
Proper wheel flanges support the wheel thus
reducing the possibility of wheel breakage. Flanges
for cut-off wheels may bedifferent from grinding
wheel flanges.
f) Do not use worn down wheels from larger power
tools. Wheelsintended for larger power toolsare
not suitable for the higher speed of a smaller tool
and may burst.

materials. Never use the device towork onany
materials containing asbestos!
d) Sparks generated during working orsplinters,
chips and dust emitted bythe device can cause
loss of sight.
e) This safety guard is designed for
sanding/grinding.

AG820 04
