Additional safety warnings for grinding and cut-
off grinding
Safety warnings specific for grinding and cut-off
grinding:
Use only grinding accessories that are approved for
your power tool and only for the recommended applica-
tions. Example: Never grind with the lateral surface of
a cutting disc. Cutting discs are intended for material
removal using the edge of the disc. Lateral force
exerted on these grinding accessories can cause them
to break.
For threaded conical and straight grinding
points/accessories, use only undamaged mandrels of
correct size and length with an unrelieved shoulder
flange. Suitable mandrels will reduce the possibility of
breakage.
Do not jam or seize the cutting disc or apply excessive
pressure. Do not make excessively deep cuts. Over-
stressing the cutting disc increases the loading and sus-
ceptibility to wedging or binding in the cut, and thus
increases the possibility of kickback or disc breakage.
Keep your hands clear of the area in front and behind
the rotating cutting disc. When moving the cutting disc
in the workpiece away from your hand, possible kick-
back may propel the power tool with the spinning disc
directly at you.
If the cutting disc should become jammed or when
interrupting work, switch the power tool off and hold it
motionless until the disc has come to a complete stop.
Never attempt to remove a still running cutting disc
from the cut, otherwise there is danger of kickback.
Determine and correct the cause for the jamming.
Do not switch the power tool on again as long as the
disc is still in the workpiece. Allow the cutting disc to
reach its full speed first before carefully continuing
with the cut. Otherwise the disc can bind, be forced out
of the workpiece or cause kickback.
Support panels or large workpieces to minimise the risk
of kickback from a jammed cutting disc. Large work-
pieces tend to sag under their own weight. The work-
piece must be supported on both sides of the cutting
disc, near the cut and also at the edges of the work-
piece.
Use extra caution when making "pocket cuts" into
existing walls or other blind areas. The protruding cut-
ting disc may cut gas or water pipes, electrical wiring or
other objects that can cause kickback.
Additional safety warnings for working with wire
brushes
Safety warnings specific for wire brushing oper-
ations (GSZ8-90PEL, GSZ11-90PERL, GSZ4-90EL):
Be aware that wire bristles are thrown by the brush
even during ordinary operation. Do not overstress the
wires by applying excessive load to the brush. The wire
bristles can easily penetrate light clothing and/or skin.
Allow brushes to run at operating speed for at least one
minute before using them. During this time, make sure
that no one is standing in front or in line with the brush.
Loose bristles or wires can be discharged or thrown off
during the run-in time.
Direct the rotating wire brush away from yourself. Small
particles and tiny wire fragments may be discharged at
high velocity during the use of these brushes, and may
penetrate through your skin.
Safety warnings specific for polishing operations
(GSZ8-90PEL, GSZ11-90PERL, GSZ4-90EL):
Do not allow for any loose parts of the polishing bon-
nets, especially fastening cords. Stow away or shorten
the fastening cords. Loose, rotating fastening cords can
take hold of your fingers or become caught or entan-
gled in the workpiece.
Further safety warnings
Make sure that the application tools are mounted in
accordance with the manufacturers instructions. The
mounted application tools must be able to rotate freely.
Incorrectly mounted application tools can become
loose during operation and be thrown from the
machine.
Handle grinding accessories carefully and store them
according to the manufacturer's instructions. Damaged
grinding accessories can develop cracks and burst dur-
ing operation.
When using application tools with a threaded insert,
take care that the thread in the application tool is long
enough to hold the spindle length of the power tool. The
thread in the application tool must match the thread on
the spindle. Incorrectly mounted application tools can
loosen during operation and cause injuries.
Do not direct the power tool against yourself, other per-
sons or animals. Danger of injury from sharp or hot
application tools.
Beware of any concealed electric cables, gas or water
conduits. Check the working area before commencing
work, e. g. with a metal detector.
Use a stationary extraction system, blow out ventilation
slots frequently and connect a residual current device
(RCD) on the line side. When working metal under
extreme operating conditions, it is possible for conduc-
tive dust to settle in the interior of the power tool. The
total insulation of the power tool can be impaired.
Do not rivet or screw any name-plates or signs onto the
power tool. If the insulation is damaged, protection
against an electric shock will be ineffective. Adhesive
labels are recommended.
Before putting into operation, check the mains connec-
tion and the mains plug for damage.
Recommendation: The tool should always be supplied
with power via a residual current device (RCD) with a
rated current of 30 mA or less.
