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.

safety warnings
Safety Warnings Common for Grinding:
a) This power tool is intended to function as a
grinder. 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) This power tool is not recommended for sand-
ing, wire brushing, polishing or cutting-off.
Operations for which the power tool was not de-
signed may create a hazard and cause personal
injury.
c) 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.
d) 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 fly apart
.
e) 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.
f) Threaded mounting of accessories must
match the grinder spindle thread. For acces-
sories mounted by flanges, the arbour hole of
the accessory must fit the locating diameter
of the flange.
Accessories that do not match the
mounting hardware of the power tool will run out of
balance, vibrate excessively and may cause loss of
control.
g) 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.
Dam-
aged accessories will normally break apart during
this test time.
h) Wear personal protective equipment. Depend-
ing on application, use face shield, safety gog-
gles or safety glasses. As appropriate, wear
dust mask, hearing protectors, gloves and
workshop apron capable of stopping small
abrasive or workpiece fragments.
The eye pro-
tection 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.
i) 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 fly away and cause injury beyond immediate
area of operation.
j) Hold the power tool by insulated gripping
surfaces only, when performing an operation
where the cutting accessory may contact hid-
den wiring.
Cutting accessory contacting a “live”
wire may make exposed metal parts of the power
tool “live” and could give the operator an electric
shock.
k) 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.
l) 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.
m) Do not run the power tool while carrying it at
your side.
Accidental contact with the spinning
accessory could snag your clothing, pulling the ac-
cessory into your body.
n) 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.
o) Do not operate the power tool near flammable
materials. S
parks could ignite these materials.
p) Do not use accessories that require liquid
coolants.
Using water or other liquid coolants may
result in electrocution or shock.
Further safety instructions for all operations
Kickback and Related Warnings
Kickback is a sudden reaction to a pinched or snagged
rotating wheel, backing pad, brush or any other acces-
sory. 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 enter-
ing 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 in
-
correct operating procedures or conditions and can be
avoided by taking proper precautions as given below.
a) Maintain a firm 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 kick-
back or torque reaction during start-up.
The
operator can control torque reactions or kickback
