Service
Have your power tool serviced by a qualified repair
u
person using only identical replacement parts. This
will ensure that the safety of the power tool is maintained.
Safety instructions for all applications
Safety warnings common for grinding or carving
This power tool is intended to function as a grinder or
u
carving tool. Read all safety warnings, instructions, il-
lustrations and specifications provided with this
power tool. Failure to follow all instructions listed below
may result in electric shock, fire and/or serious injury.
Operations such as sanding, wire brushing, polishing
u
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 per-
sonal injury.
Do not use accessories which are not specifically de-
u
signed 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 grinding accessories must be
u
at least equal to the maximum speed marked on the
power tool. Grinding accessories running faster than
their rated speed can break and fly apart.
The outside diameter and the thickness of your ac-
u
cessory must be within the capacity rating of your
power tool. Incorrectly sized accessories cannot be ad-
equately controlled.
The arbour size of wheels, sanding drums or any other
u
accessory must properly fit the spindle or collet of the
power tool. 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.
Mandrel mounted wheels, sanding drums, cutters or
u
other accessories must be fully inserted into the collet
or chuck. If the mandrel is insufficiently held and/or the
overhang of the wheel is too long, the mounted wheel
may become loose and be ejected at high velocity.
Do not use a damaged accessory. Before each use in-
u
spect the accessory such as abrasive wheels for chips
and cracks, sanding drum for cracks, tear or excess
wear, wire brush for loose or cracked wires. If power
tool or accessory is dropped, inspect for damage or in-
stall an undamaged accessory. After inspecting and
installing an accessory, position yourself and bystand-
ers 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.
Wear personal protective equipment. Depending on
u
application, use face shield, safety goggles or safety
glasses. As appropriate, wear dust mask, hearing pro-
tectors, gloves and workshop apron capable of stop-

ping small abrasive or workpiece fragments. The eye
protection must be capable of stopping flying debris gen-
erated 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.
Keep bystanders a safe distance away from work area.
u
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.
Hold power tool by insulated gripping surfaces only,
u
when performing an operation where the cutting ac-
cessory may contact hidden wiring or its own cord.
Cutting accessory contacting a "live" wire may make ex-
posed metal parts of the power tool "live" and could give
the operator an electric shock.
Always hold the tool firmly in your hand(s) during the
u
start-up. The reaction torque of the motor, as it acceler-
ates to full speed, can cause the tool to twist.
Use clamps to support workpiece whenever practical.
u
Never hold a small workpiece in one hand and the tool
in the other hand while in use. Clamping a small work-
piece allows you to use your hand(s) to control the tool.
Round material such as dowel rods, pipes or tubing have
a tendency to roll while being cut, and may cause the bit
to bind or jump toward you.
Position the cord clear of the spinning accessory. If
u
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 accessory has
u
come to a complete stop. The spinning accessory may
grab the surface and pull the power tool out of your con-
trol.
After changing the bits or making any adjustments,
u
make sure the collet nut, chuck or any other adjust-
ment devices are securely tightened. Loose adjustment
devices can unexpectedly shift, causing loss of control,
loose rotating components will be violently thrown.
Do not run the power tool while carrying it at your
u
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
u
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 flammable materi-
u
als. Sparks could ignite these materials.
Do not use accessories that require liquid coolants.
u
Using water or other liquid coolants may result in electro-
cution or shock.
Kickback and related warnings
Kickback is a sudden reaction to a pinched or snagged rotat-
ing wheel, sanding band, brush or any other accessory.
Pinching or snagging causes rapid stalling of the rotating ac-
