In case of short energy-containing pulses in the supply sys-
tem, which typically develop when lightning strikes, the pow-
er tool's kickback stop may actuate. If so, the machine will
switch off, yet can be restarted again thereafter immediately.
Restarting Protection (GWS 24-230 LVJ/
GWS 24-180 LVI/GWS 24-230 LVI/GWS 26-230 LVI)
The restarting protection feature prevents uncontrolled re-
starting of the machine after an interruption in the power sup-
ply.
To restart the operation, switch the On/Off switch 3 to the
Off position and start the machine again.
Reduced starting current (GWS 24-230 LVJ/
GWS 24-180 LVI/GWS 24-230 LVI/GWS 26-230 LVI)
The electronic reduced starting current limits the power con-
sumption when switching the tool on and enables operation
from a 13 ampere fuse.
Note: When the machine runs with full speed after switching
on, the reduced starting current, the restarting protection
and the kickback stop features have failed. The power tool
must promptly be sent to an after-sales service agent for
maintenance; addresses, see Section „After-sales Service
and Application Service".
Working Advice
Exercise caution when cutting slots in structural walls;
see Section "Information on Structures".
Clamp the workpiece if it does not remain stationary
due to its own weight.
Do not strain the machine so heavily that it comes to a
standstill.
After heavily straining the power tool, continue to run
it at no-load for several minutes to cool down the acces-
sory.
Do not touch grinding and cutting discs before they
have cooled down. The discs can become very hot while
working.
Do not use the power tool with a cut-off stand.
Note: When not using for extended periods, pull the mains
plug out of the socket outlet. When the mains plug is inserted
and mains voltage is given, the power tool, even when
switched off, still consumes a low amount of current.
Rough Grinding
Never use a cutting disc for roughing.
The best roughing results are achieved when setting the ma-
chine at an angle of 30° to 40°. Move the machine back and
forth with moderate pressure. In this manner, the workpiece
will not become too hot, does not discolour and no grooves
are formed.
Flap Disc
With the flap disc (accessory), curved surfaces and profiles
can be worked.
Flap discs have a considerably higher service life, lower noise
levels and lower sanding temperatures than conventional
sanding sheets.
Bosch Power Tools
Cutting Metal
For cutting with bonded abrasives, always use the pro-
tection guard for cutting 14.
When cutting, work with moderate feed, adapted to the mate-
rial being cut. Do not exert pressure onto the cutting disc, tilt
or oscillate the machine.
Do not reduce the speed of running down cutting discs by ap-
plying sideward pressure.
Cutting Stone
Provide for sufficient dust extraction when cutting
stone.
Wear a dust respirator.
The machine may be used only for dry cutting/grinding.
For cutting stone, it is best to use a diamond cutting disc.
When using the cutting guide with dust extraction protection
guard 25, the vacuum cleaner must be approved for vacuum-
ing masonry dust. Suitable vacuum cleaners are available
from Bosch.
clearly indicated by circular sparking, rotating with the dia-
mond cutting disc.
In this case, interrupt the cutting process and allow the dia-
mond cutting disc to cool by running the machine for a short
time at maximum speed with no load.
Noticeable decreasing work progress and circular sparking
are indications of a diamond cutting disc that has become
dull. Briefly cutting into abrasive material (e. g. lime-sand
brick) can resharpen the disc again.

The machine must al-
ways work in an up-
grinding motion. Other-
wise, the danger exists
of it being pushed un-
controlled out of the
cut.
When cutting profiles
and square bar, it is best
to start at the smallest
cross section.
Switch on the machine
and place the front part
of the cutting guide on
the workpiece. Slide the
machine with moderate
feed, adapted to the ma-
terial to be worked.
For cutting expecially
hard material, e. g., con-
crete with high pebble
content, the diamond
cutting disc can over-
heat and become dam-
aged as a result. This is
