o) Do not operate the power tool near
flammable materials. Sparks could ignite these
materials.
p) Do not use accessories that require liquid
coolants. Using water or other liquid coolants may
result in electrocution or shock.
3.2 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 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.
3.3 Safety Warnings Specific for Polishing:
Do not allow any loose portion of the polishing
bonnet or its attachment strings to spin freely.
Tuck away or trim any loose attachment
strings. Loose and spinning attachment strings
can entangle your fingers or snag on the workpiece.
3.4 Additional Safety Instructions
WARNING – Always wear protective
goggles.

Use elastic cushioning layers if they have been
supplied with the abrasive and if required.
Observe the specifications of the tool or accessory
manufacturer! Protect the discs from grease or
impacts!
Accessories must be stored and handled with care
in accordance with the manufacturer's instructions.
The workpiece must lay flat and be secured against
slipping, e.g. using clamps. Large workpieces must
be sufficiently supported.
During machining, of metals in
particular, conductive dust can form
deposits inside the machine. 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.
We recommend using a stationary extractor system
and connecting a residual current circuit-breaker
(FI) upstream. When the polisher is shut down via
the FI circuit-breaker, it must be checked and
cleaned. See chapter 8. Cleaning for more
information on cleaning the motor.
Dust from materials such as lead-containing paint
and metal may be harmful to health. Contact with or
inhalation of the dust may cause allergic reactions
and/or respiratory diseases to the operator or
bystanders.
Certain kinds of dust are classified as carcinogenic.
Material containing asbestos must only be treated
by specialists.
- Where the use of a dust extraction device is
possible it shall be used.
- The work place must be well ventilated.
- The use of a dust mask of filter class P2 is
recommended.
Follow national requirements for the materials you
want to work with.
Materials that generate dusts or vapours that may
be harmful to health (e.g. asbestos) must not be
processed.
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.
Connect a FI circuit-breaker with max.
release current (30 mA) upstream when using the
machine outdoors!
Pull the plug out of the socket before making any
adjustments, converting or servicing the machine.
A damaged or cracked additional handle must be
replaced. Never operate a machine with a defective
additional handle.
A damaged or cracked hand guard must be
replaced. Never operate a machine with a defective
hand guard.
