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 injuries.
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) The substitution of the brushes of the power tool
should be accomplished by an authorized and
qualified technical service. Brushes out of
specification can cause damages to the motor of the
power tool.
Safety warnings that are common for
grinding, sanding, wire brushing, polishing
and abrasive cutting off operations:
a) This power tool is intended to function as a
grinder, sander, wire brush, polisher or cut-off
tool. Read all safety warnings, instructions,
illustrations and specifications provided with this
power tool. Failure to follow all instructions listed
below may result in electric shock, fire and/or
serious injury.
b) Do not use accessories which are not specifically
designed and recommended by the tool
manufacturer. Just because the accessory can be
attached to your power tool, it does not assure
safe operation.
c) 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 fly apart.
d) 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.
e) The arbour size of wheels, flanges, backing pads
or any other accessory must properly fit the
spindle of the power tool. Accessories with arbour
holes that do not match the mounting hardware of
the power tool will run out of balance, vibrate
excessively and may cause loss of control.
f) Do not use a damaged accessory. Before each
use inspect the accessory such as abrasive
wheels for chips and cracks, backing pads for
cracks, tear or excess wear, wire brushes for
loose or cracked wires. If the power tool or
accessory 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 accessories
will normally break apart during this test time.
g) Wear personal protective equipment. Depending
on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask,
hearing protectors, gloves and shop apron
capable of stopping small abrasive or workpiece
fragments. The eye protection must be capable of
stopping flying debris generated by various
operations. The dust mask or respirator must be
capable of filtrating particles generated by your
operation. Prolonged exposure to high intensity
noise may cause hearing loss.
h) Keep bystanders a safe distance away from work
area. Anyone entering the work area must wear
personal protective equipment. Fragments of the
workpiece or of a broken accessory may fly away
and cause injury beyond the immediate area of
operation.
i) Hold the power tool only by the insulated
gripping surfaces when performing an operation
where the cutting tool may contact hidden wiring
or its own power cord. Contact with a "live" wire
will also make exposed metal parts of the power
tool "live" and shock the operator.
j) Position the cord clear of the spinning accessory.
If you lose control, the cord may be cut or snagged
and your hand or arm may be pulled into the
spinning accessory.
k) Never lay the power tool down until the
accessory has come to a complete stop. The
spinning accessory may grab the surface and pull
the power tool out of your control.
l) 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.
m)
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.
n) Do not operate the power tool near flammable
materials. Sparks could ignite these materials.
o) Do not use accessories that require liquid
coolants. 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
