accessory could snag your clothing, pulling the
accessory into your body.
m) 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.
n) Do not operate the power tool near
flammable materials. Sparks could ignite these
materials.
4.2 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.
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
surface 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 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.
a) Maintain a firm grip on the power tool and
position your body and arm to allow you to
resist kickback forces. Always use the auxiliary
handle, if provided, for maximum control over
kickback or torque reaction during start-up.
The operator can control torque reactions or
kickback forces, if proper precautions are taken.
b) Never place your hand near the rotating
accessory. Accessory may kickback over your
hand.
c) Do not position your body in the area
where power tool will move if kickback occurs.
Kickback will propel
the tool in direction opposite to the wheel's
movement at the point of snagging.
d) Use special care when working corners,
sharp edges etc. Avoid bouncing and snagging
the accessory. Corners, sharp edges or bouncing
have a tendency to snag the rotating accessory and
cause loss of control or kickback.
e) Do not attach a saw chain woodcarving
blade or toothed saw blade. Such blades create
frequent kickback and loss of control.
4.3 Safety Warnings Specific for Polishing:
Loose parts on the polishing guard, especially
the fastening cords, are not permitted. Tuck
away or shorten the fastening cords. Loose,
spinning fastening cords may make contact with
your fingers or become caught in the workpiece.

4.4 Additional Safety Instructions
Use elastic cushioning layers if they have been
supplied with the abrasive and if required.
Observe the specifications of the tool or accessory
manufacturer!
Accessories must be stored and handled with care
in accordance with the manufacturer's instructions.
Ensure that accessories are installed in accordance
with the manufacturer's instructions.
The tool continues running after the machine has
been switched off.
The workpiece must lay flat and be secured against
slipping, e.g. using clamps. Large workpieces must
be sufficiently supported.
If accessories with threaded inserts are used, the
end of the spindle may not touch the base of the
hole on the grinding tool. Make sure that the thread
in the accessory is long enough to accommodate
the full length of the spindle. The thread in the
accessory must match the thread on the spindle.
See page 2 and chapter 13. Technical
Specifications for more information on the spindle
length and thread.
Always wear protective goggles.
Conductive dust may collect inside
the machine during the process.
This can lead to the transfer of electrical energy
onto the machine housing. This can mean a
temporary danger of electric shocks. This is why it is
necessary when the machine is running to blow
compressed air through the rear ventilation slots of
the machine regularly, frequently and thoroughly.
Here, the machine must be held firmly.
When working in dusty conditions, ensure that
ventilation openings are not blocked. If it becomes
necessary to remove dust, first disconnect the
power tool from the mains supply (use non-metallic
objects) and avoid damaging internal components.
Damaged, eccentric or vibrating tools must not be
used.
Pull the plug out of the socket before making any
adjustments, converting or servicing the machine.
Avoid inadvertent starts by always unlocking the
switch when the plug is removed from the mains
socket or in case of a power cut.
Metabo S-automatic safety clutch. When the safety
clutch responds, switch off the machine
immediately!
A damaged or cracked additional handle must be
replaced. Never operate a machine with a defective
additional handle.
Reduce dust exposure:
Some dust created by using this power tool
may contain chemicals known to cause
cancer, allergic reaction, respiratory disease, birth
defects or other reproductive harm. Some
examples of these chemicals are: Lead from lead-
based paints, crystalline silica from bricks and
cement and other masonry products, Arsenic and
