Service
▶ 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.
▶ Never service damaged battery packs. Service of battery packs should only be performed by the
manufacturer or authorized service providers.
2.2 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
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 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 accessory must be within the capacity rating of
your power tool. Incorrectly sized accessories cannot be adequately controlled.
▶ The arbour 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 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 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 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.
▶ Wear personal protective equipment. Depending on application, use face shield, safety goggles or
safety glasses. As appropriate, wear dust mask, hearing protectors, gloves and workshop 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.
▶ 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 accessory 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
accelerates 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 workpiece 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.
▶ 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.
▶ After changing the bits or making any adjustments, make sure the collet nut, chuck or any other
adjustment 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 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.
