For you safety
Read all instructions. Failure to follow all instructions listed
below may result in electric shock, fire and/or serious injury.
Additionally, the general safety instructions on page 14 must
be followed.
SAVE THESE INSTRUCTIONS.
! Wear safety goggles.
! Wear hearing protection.
! When working with the machine, always hold it firmly with both
hands and provide for a secure stance. The power tool is guided
more secure with both hands.
! Secure the workpiece. A workpiece clamped with clamping
devices or in a vice is held more securely than by hand.
! Take protective measures when dust can develop during
working that is harmful to one's health, combustible or
explosive. Example: Some dusts are regarded as carcinogenic.
Work with dust/chip extraction and wear a dust mask.
! Keep your workplace clean. Material mixtures are particularly

dangerous. Dust of light metal can be inflammable or explode.
! Do not work materials containing asbestos. Asbestos is
considered carcinogenic.
! Do not use a machine with a damaged mains cable. Do not
touch the damaged cable and pull the mains plug when the
cable is damaged while working. Damaged cables increase the
risk of an electric shock.
! Connect machines that are used in the open via a residual
current device (RCD).
Safety warnings that are common for grinding, sanding, wire
brushing, polishing and abrasive cutting off operations:
! This power tool is intended to function as a grinder, sander,
wire brush, polisher 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 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 cannot 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
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 shop 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 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 gripping surfaces
when performing an operation where the cutting tool may
contact hidden wiring 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.
! 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
