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
3 forward and then down.
To lock-on the pressed On/Off switch 3, push
the On/Off switch 3 further forward.
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.
Bosch Power Tools
Run-on Brake (GWS 24-230 JBX)
The power tool is equipped with
the Bosch Brake System, a patent-
ed electromechanical run-on
brake.
When switching off or when the power supply is
interrupted, the machine comes to a complete
stop within a few seconds. This means a reduc-
tion of the run-on time of approx. 70 % when
compared with angle grinders without run-on
brake, which allows for the power tool to be
placed down sooner.
Note: When the braking effect decreases notice-
ably, the run-on brake has failed. The power tool
should be sent immediately to an after-sales
service (for addresses, see section "After-sales
Service and Customer Assistance".
Restarting Protection
(3 601 H64 T../3 601 H55 U../3 601 H56 U..)
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 (GWS 24-230 JBX/
GWS 26-180 JBV/GWS 26-230 JBV)
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".
