handle. Contact with the mains lead may cause voltage to be
transmitted to the metal parts of the tool, which could result in
electric shock.
• Never put the appliance down before the working tool has come to
a complete stop. A rotating tool may come into contact with the
surface on which it is put down, so you could lose control of the unit.
• Do not carry the machine while it is in motion. Accidental contact of
clothing with a rotating work tool may cause it to be pulled in and the
work tool to drill into the operator's body.
• Clean the ventilation slots of the unit regularly. The motor blower
draws dust into the housing and a large accumulation of metal dust
can cause an electrical hazard.
• Do not use the unit near flammable materials. Sparks may ignite
them.
• Do not use tools that require liquid coolants. The use of water or
other liquid coolants can lead to electric shock.
DISCARD AND SAFETY NOTES
• Kickback is the sudden reaction of the machine to the blockage or
obstruction of a rotating tool such as a grinding wheel, sanding pad,
wire brush, etc. The snagging or blocking leads to a sudden stop of
the rotating work tool. An uncontrolled device will thus be jerked in
the direction opposite to the direction of rotation of the work tool.
When, for example, the grinding wheel jams or becomes jammed in
the workpiece, the immersed edge of the grinding wheel can
become blocked and cause it to fall out or eject. The movement of
the grinding wheel (towards or away from the operator) is then
dependent on the direction of movement of the wheel at the point of
blockage. In addition, grinding wheels can also break.
• Recoil is a consequence of improper or incorrect use of the device.
It can be avoided by taking the appropriate precautions described
below.
• The device should be held firmly, with the body and hands
in a position to soften the recoil. If an auxiliary handle is
included as part of the standard equipment, it should always
be used in order to have the greatest possible control over
the recoil forces or the recoil moment during start-up. The
operator can control the jerk and recoil phenomena by taking
appropriate precautions.
• Never hold hands near rotating work tools. The working tool
may injure your hand due to recoil.
• Keep away from the range zone where the device will move
during recoil. As a result of recoil, the device moves in the
opposite direction to the movement of the grinding wheel at the
point of blockage.
• Be particularly careful when machining corners, sharp
edges, etc. Prevent the working tools from being deflected
or becoming blocked.
• A rotating work tool is more susceptible to jamming when
machining angles, sharp edges or if it is kicked back. This can
become a cause of loss of control or kickback.
• Do not use wood or toothed discs.
• Work tools of this type often result in recoil or loss of control.
SPECIAL SAFETY INSTRUCTIONS FOR GRINDING AND CUTTING
WITH A GRINDING WHEEL
• Only use a grinding wheel designed for the machine and a
guard designed for the wheel. Grinding wheels that are not
tooling for a particular machine cannot be sufficiently shielded and
are not sufficiently safe.
• Bent grinding discs must be mounted in such a way that their
grinding surface does not protrude beyond the edge of the
protective cover. An improperly fitted grinding disc that protrudes
beyond the edge of the protective cover cannot be sufficiently
protected.
• The guard must be firmly attached to the machine to guarantee
the greatest possible degree of safety - positioned so that the
part of the grinding wheel exposed and facing the operator is
as small as possible. The guard protects the operator from debris,
accidental contact with the grinding wheel, as well as sparks that
could ignite clothing.
• Grinding wheels may only be used for the work intended for
them.
• For example, never grind with the side surface of a cut-off
wheel. Cut-off wheels are designed to remove material with the
edge of the disc. The effect of lateral forces on these grinding wheels
can break them.
• Always use undamaged clamping flanges of the correct size
and shape for the selected grinding wheel. Proper flanges
support the grinding wheel and thus reduce the danger of the wheel
breaking. Flanges for cut-off wheels may differ from those for other
grinding wheels.
• Do not use worn grinding wheels from larger machines.
Grinding wheels for larger machines are not designed for the higher
RPM that is a characteristic of smaller machines and may therefore
break.
ADDITIONAL SPECIFIC SAFETY INSTRUCTIONS FOR GRINDING
WHEEL CUTTING
• Avoid jamming of the cutting disc or too much pressure. Do not
make excessively deep cuts. Overloading the cutting disc
increases the load on the blade and its tendency to jam or block and
thus the possibility of discarding or breaking.
• Avoid the area in front of and behind the rotating cutting disc.
Moving the cutting disc in the workpiece away from you may cause
the machine to recoil with the rotating disc directly towards you in
the event of a kickback.
• In the event of a jammed cutting disc or a stoppage, switch off
the machine and wait until the disc has come to a complete
stop. Never attempt to pull the still-moving disc out of the
cutting area, as this may cause recoil. The cause of the jam must
be detected and removed.
• Do not restart the machine while it is in the material. The cutting
wheel should reach its full speed before continuing to cut.
Otherwise, the grinding wheel may catch, jump off the workpiece or
cause recoil.
• Plates or large objects should be supported before machining
to reduce the risk of kickback caused by a jammed disc. Large
workpieces may bend under their own weight. The workpiece should
be supported on both sides, both near the cutting line and at the
edge.
• Take special care when cutting holes in walls or operating in
other invisible areas. The cutting disc plunging into the material
may cause the tool to recoil if it encounters gas pipes, water pipes,
electrical cables or other objects.
SPECIAL SAFETY
SANDPAPER
• Do not use oversized sheets of sandpaper. When selecting the
sanding paper size, follow the manufacturer's recommendations.
Sanding paper protruding beyond the sanding plate can cause injury
and can lead to the paper becoming blocked or torn, or to recoil.
SPECIAL SAFETY INSTRUCTIONS FOR WORKING WITH WIRE
BRUSHES
• It should be taken into account that even with normal use, there is a
loss of pieces of wire through the brush. Do not overload the wires
by applying
Airborne pieces of wire can easily pierce through thin clothing
and/or skin.
• If a guard is recommended, prevent the brush from coming into
contact with the guard. The diameter of plate and pot brushes can
increase through pressure and centrifugal forces.
• Always wear safety goggles when working with wire brushes.
ADDITIONAL SAFETY INFORMATION
• Remove the battery from the unit before all installation work.
• Grinding tools must be checked before use. The sanding tool must
be fitted correctly and must rotate freely. As part of the test, run the
machine without load for at least one minute in a safe position. Do
not use damaged or vibrating grinding tools. Grinding tools must be
round in shape. Damaged sanding tools may break and cause
injury.
• After fitting the sanding tool and before starting the sander, check
that the sanding tool is properly fitted, that it rotates freely and that
it does not catch on the guard.
• The spindle lock button can only be operated when the grinding
spindle is stationary.
• On tools designed to accommodate tapped grinding wheels, check
that the length of the grinding wheel thread is appropriate to the
length of the spindle thread.
• The workpiece must be secured. Clamping the workpiece in a
clamping device or vise is safer than holding it in your hand.
• If the object's own weight does not guarantee a stable position, it
must be fixed.
• Do not touch the cutting and grinding discs before they have cooled
down.
• Do not exert lateral pressure on the grinding or cutting disc.
Do not cut workpieces thicker than the maximum cutting depth of
the cutting disc.
• When using a quick-action flange, ensure that the inner flange fitted
to the spindle is fitted with a rubber O-ring and that this ring is not
