Working Advice - Bosch GWS Professional 22-180 LVI Originalbetriebsanleitung

To switch off the power tool, release the On/Off
switch 3, or when it is locked, briefly press the
On/Off switch 3 and then release it.
Switch Version without Lock-on
(country-specific):
To start the power tool, press the On/Off switch
3 forward and then down.
To switch off the machine, release the On/Off
switch 3.
Check grinding tools before using. The
grinding tool must be mounted properly
and be able to move freely. Carry out a test
run for at least one minute with no load. Do
not use damaged, out-of-centre or vibrating
grinding tools. Damaged grinding tools can
burst and cause injuries.
Kickback stop
In case of a sudden drop in speed,
e.g., caused by a jammed disc
while cutting, the power supply to
the motor is electronically inter-
rupted.
To restart the operation, switch the On/Off
switch 3 to the Off position and start the ma-
chine again.
Note: When the machine only runs with heavily
reduced speed, the kickback stop feature has
failed. The power tool must promptly be sent to
an after-sales service agent for maintenance; ad-
dresses, see Section „After-sales Service and
Customer Assistance".
Restarting Protection
The restarting protection feature prevents un-
controlled restarting of the machine after an in-
terruption in the power supply.
To restart the operation, switch the On/Off
switch 3 to the Off position and start the ma-
chine again.
Reduced starting current
The electronic reduced starting current limits
the power consumption when switching the tool
on and enables operation from a 13 ampere
fuse.
Bosch Power Tools
Note: When the machine runs with full speed af-
ter 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 Customer Assistance".

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, con-
tinue to run it at no-load for several minutes
to cool down the cutting/grinding tool.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
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 machine 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 tem-
peratures than conventional sanding sheets.
Cutting Metal
For cutting metal, always work with the pro-
tection guard for cutting 14.
