Operation
Starting Operation
Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V
can also be operated with 220 V.
When operating the machine with power from
mobile generators that do not have sufficient re-
serve capacity or are not equipped with suitable
voltage control with starting current amplifica-
tion, loss of performance or untypical behavior
can occur upon switching on.
Please observe the suitability of the power gen-
erator being used, particularly with regard to
the mains voltage and frequency.
Switching On and Off
To start the power tool, press the On/Off switch
2 forward and then down.
To lock-on the pressed On/Off switch 2, push
the On/Off switch 2 further forward.
To switch off the power tool, release the On/Off
switch 2, or when it is locked, briefly press the
On/Off switch 2 and then release it.
Switch Version without Lock-on
(country-specific):
To start the power tool, press the On/Off switch
2 forward and then down.
To switch off the machine, release the On/Off
switch 2.
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.

Restarting Protection
(GWS 22-180 JH/GWS 22-230 JH/
GWS 24-180 JH/GWS 24-230 JH/
GWS 26-180 JH/GWS 26-230 JH)
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 2 to the Off position and start the ma-
chine again.
Reduced starting current
(GWS 22-180 JH/GWS 22-230 JH/
GWS 24-180 JH/GWS 24-230 JH/
GWS 26-180 JH/GWS 26-230 JH)
The electronic reduced starting current limits
the power consumption when switching the tool
on and enables operation from a 13 ampere
fuse.
Note: When the machine runs at full speed im-
mediately after switching on, the reduced start-
ing current and the restarting protection have
failed. The power tool should be sent immedi-
ately to an after-sales service (for 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 accessory.
Grinding and cutting discs become very hot
while working; do not touch until they have
cooled.
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.
