Safety warnings that are common for
grinding, sanding with sanding discs, wire
brushing and cut-off grinding
This power tool is intended to function as a grinder,
sander, wire brush and cut-off tool. Observe all
safety warnings, instructions, illustrations and data
provided with this power tool. Failure to follow all
instructions listed below may result in electric shock,
fire and/or serious injury.
This power tool is not suitable for polishing. Appli-
cations, for which the power tool is not intended for,
can lead to hazardous situations and injury.
Do not use accessories which are not specifically
designed and recommended by the tool manufac-
turer. 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 fly apart.
The outside diameter and the thickness of your
accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories can-
not be adequately guarded or controlled.
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.
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 acces-
sory. 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 dur-
ing this test time.
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 frag-
ments. The eye protection must be capable of stop-
ping flying debris generated by various operations.
The dust mask or respirator must be capable of fil-
12
For Your Safety
trating particles generated by your operation. Pro-
longed 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 the
workpiece or of a broken accessory may fly away
and cause injury beyond the immediate area of
operation.
Hold the power tool only by the insulated grip-
ping surfaces when performing an operation
where the cutting tool may contact hidden wir-
ing 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.
Never lay the power tool down until the accessory
has come to a complete stop. The spinning acces-
sory 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 flammable
materials. Sparks could ignite these materials.
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 direc-
tion 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 sur-
face 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 the 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 firm grip on the power tool and position
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 reac-
tions or kickback forces, if proper precautions are taken.
