The term "power tool" in the warnings refers to your mains-operated (corded) power tool or
battery-operated (cordless) power tool.
POWER TOOL USE AND CARE
SERVICE
• Keep work area clean and well lit. Cluttered or
dark areas invite accidents.
• Do not operate power tools in explosive atmo-
spheres, such as in the presence of fl ammable
liquids, gases or dust. Power tools create sparks
which may ignite the dust or fumes.
• Keep children and bystanders away while
operating a power tool. Distractions can cause
you to lose control.
• 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.
• Avoid body contact with earthed or grounded
surfaces such as pipes, radiators, ranges and
refrigerators. There is an increased risk of elec-
tric shock if your body is earthed or grounded.
• Do not expose power tools to rain or wet con-
ditions. Water entering a power tool will increase
the risk of electric shock.
• 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.
• 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.
• 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.
• 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.
• Do not overreach. Keep proper footing and
balance at all times. This enables better control
of the power tool in unexpected situations.
• Dress properly. Do not wear loose clothing or
jewellery. Keep your hair, clothing and gloves
away from moving parts. Loose clothes, jewel-
lery or long hair can be caught in moving parts.
• 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.
• 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.
• 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.
• 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.
• Store idle power tools out of the reach of chil-
dren 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.
• Maintain power tools. Check for misalignment
or binding of moving parts, breakage of parts
and any other condition that may affect the
power tool operation. If damaged, have the
power tool repaired before use. Many accidents
are caused by poorly maintained power tools.
• Keep cutting tools sharp and clean. Properly
maintained cutting tools with sharp cutting edges
are less likely to bind and are easier to control.
• 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.
• 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.
• 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 medi-
cation. A moment of inattention while operating
power tools may result in serious personal injury.
• 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.
• 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 fi nger on the switch or energising power
tools that have the switch on invites accidents.
SPECIFIC SAFETY RULES • Hold power tool by insulated gripping surfaces
only, 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 shock the operator.
• Position the cord clear of the spinning acces-
sory. If you lose control, the cord may be cut or
snagged and your hand or arm may be pulled into
the spinning accessory.
• Never lay the power tool down until the acces-
sory has come to a complete stop. The spinning
accessory may grab the surface and pull the power
tool out of your control.
• Do not run the power tool while carrying it at
your side. Accidental contact with the spinning
accessory could snag your clothing, pulling the
accessory into your body.
• Regularly clean the power tool’s air vents. The
motor’s fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
• Do not operate the power tool near fl ammable
materials. Sparks could ignite these materials.
• Do not use accessories that require liquid cool-
ants. Using water or other liquid coolants may result
in electrocution or shock.
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or
snagged rotating wheel, backing pad, brush or
any other accessory. Pinching or snagging causes
rapid stalling of the rotating accessory which in turn
causes the uncontrolled power tool to be forced in
the direction opposite of the accessory’s rotation at
the point of the binding.
For example, if an abrasive wheel is snagged or
pinched by the workpiece, the edge of the wheel
that is entering into the pinch point can dig into
the surface of the material causing the wheel to
climb out or kick out. The wheel may either jump
toward or away from the operator, depending on
direction of the wheel’s movement at the point of
pinching. Abrasive wheels may also break under
these conditions.
Kickback is the result of power tool misuse and/or
incorrect operating procedures or conditions and
can be avoided by taking proper precautions as
given below.
• Maintain a fi rm grip on the power tool and posi-
tion your body and arm to allow you to resist
kickback forces. Always use auxiliary handle,
if provided, for maximum control over kickback
or torque reaction during start-up. The operator
can control torque reactions or kickback forces, if
proper precautions are taken.
• Never place your hand near the rotating acces-
sory. Accessory may kick back over your hand.
• Do not position your body in the area where
power tool will move if kickback occurs. Kick-
back will propel the tool in direction opposite to the
wheel’s movement at the point of snagging.
• Use special care when working corners, sharp
edges etc. Avoid bouncing and snagging the
Safety Warnings Common for Grinding Opera-
tions:
• This power tool is intended to function as a
grinder. Read all safety warnings, instructions,
illustrations and specifi cations provided with
this power tool. Failure to follow all instructions
listed below may result in electric shock, fi re and/
or serious injury.
• Operations such as sanding, wire brushing,
polishing or cutting-off are not recommended to
be performed with this power tool. Operations for
which the power tool was not designed may create
a hazard and cause personal injury.
• Do not use accessories which are not specifi -
cally designed and recommended by the tool
manufacturer. Just because the accessory can be
attached to your power tool, it does not assure safe
operation.
• The rated speed of the accessory must be at
least equal to the maximum speed marked on
the power tool. Accessories running faster than
their rated speed can break and fl y apart.
• The outside diameter and the thickness of your
accessory must be within the capacity rating
of your power tool. Incorrectly sized accessories
cannot be adequately guarded or controlled.
• The arbour size of wheels, fl anges, backing
pads or any other accessory must properly fi t
the spindle of the power tool. Accessories with
arbour holes that do not match the mounting hard-
ware of the power tool will run out of balance, vibrate
excessively and may cause loss of control.
• Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pad for
cracks, tear or excess wear, wire brush for
loose or cracked wires. If power tool or acces-
sory is dropped, inspect for damage or install
an undamaged accessory. After inspecting and
installing an accessory, position yourself and
bystanders away from the plane of the rotating
accessory and run the power tool at maximum
no-load speed for one minute. Damaged accesso-
ries will normally break apart during this test time.
• Wear personal protective equipment. Depend-
ing on application, use face shield, safety
goggles or safety glasses. As appropriate, wear
dust mask, hearing protectors, gloves and work
shop apron capable of stopping small abrasive
or workpiece fragments. The eye protection
must be capable of stopping fl ying debris gen-
erated by various operations. The dust mask
or respirator must be capable of fi ltrating particles
generated by your operation. Prolonged exposure
to high intensity noise may cause hearing loss.
• Keep bystanders a safe distance away from
work area. Anyone entering the work area must
wear personal protective equipment. Fragments
of workpiece or of a broken accessory may fl y away
and cause injury beyond immediate area of opera-
tion.
