Safety warnings common for grinding,
sanding, wire brushing, polishing, carving
or abrasive cutting-off operations:
This power tool is intended to function as a grinder,
sander, wire brush, polisher, carving 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.
Do not use accessories which are not specifically
designed and recommended by the tool manufactur-
er. 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 operating speed setting marked on the
power tool. Accessories running faster than their
RATED SPEED can break and fly apart.
The outside diameter and the thickness of your acces-
sory must be within the capacity rating of your power
tool. Incorrectly sized accessories cannot be adequately
guarded or controlled.
The arbor size of wheels, sanding drums or any other
accessory must properly fit the spindle or collet of the
power tool. Accessories that do not match the mount-
ing 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
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
inspect 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 dam-
age or install an undamaged accessory. After inspect-
ing and installing an accessory, position yourself and
bystanders away
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.
Safety Rules for Cordless Rotary Tools
from the plane of
Wear personal protective equipment. Depending on
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
generated by various operations. The dust mask or res-
pirator 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.
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,
when performing an operation where the cutting
accessory may contact hidden wiring. Cutting accesso-
ry contacting a "live" wire may make exposed 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
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.
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
you lose control, the cord may be cut or snagged and
your hand or arm may be pulled into the spinning acces-
sory.
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 con-
trol.

After changing the bits or making any adjustments,
make sure the collet nut, chuck or any other adjust-
ment devices are securely tightened. Loose adjust-
