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 instructions for all operations
Safety warnings common for grinding or polishing operations:
▶ This power tool is intended to function as a grinder or polisher. 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.
▶ Operations such as sanding, wire brushing, hole cutting or cutting-off are not to be performed
with this power tool. Operations for which the power tool was not designed may create a hazard and
cause personal injury.
▶ Do not convert this power tool to operate in a way which is not specifically designed and specified
by the tool manufacturer. Such a conversion may result in a loss of control and cause serious personal
injury.
▶ Do not use accessories which are not specifically designed and specified 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 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.
▶ 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.
▶ The dimensions of the accessory mounting must fit the dimensions of the mounting hardware 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.
▶ 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 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 applications. The dust mask or respirator must be capable
of filtrating particles generated by the particular application. 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 the power tool by insulated gripping surfaces only, when performing an operation where the
cutting tool may contact hidden wiring. Contact with a "live" wire will also make exposed metal parts
of the power tool "live" and could give the operator an electric shock.
▶ 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.
▶ 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 direction opposite of the accessory's rotation at the point of the
binding.
