To lock the On/Off switch 5, press the On/Off switch 5 down
at the front until it latches.
To switch off the power tool, release the On/Off switch 5 or,
if it is locked, briefly push down the back of the On/Off switch
5 and then release it.
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 electroni-
cally interrupted.
To restart the operation, switch the On/Off switch 5 to the
Off position and start the machine again.
Constant Electronic Control
Constant electronic control holds the speed constant at no-
load and under load, and ensures uniform working perform-
ance.
Speed preselection (GGS 8 CE/GGS 28 CE/GGS 28 LCE)
The required speed can be preselected with the thumbwheel
6 (also while running).
The required speed depends on the material being worked
and the diameter of the application tool. Observe the maximal
allowable speed of the application tool.
Working Advice
Optimum grinding results are achieved when the grinding tool
is moved uniformly back and forth with light pressure. Pres-
sure that is too strong reduces the performance capability of
the machine and causes the grinding tool to wear more quick-
ly.
Maintenance and Service
Maintenance and Cleaning
f Before any work on the machine itself, pull the mains
plug.
f For safe and proper working, always keep the machine
and ventilation slots clean.
f In extreme conditions, always use dust extraction as
far as possible. Blow out ventilation slots frequently
and install a residual current device (RCD). When work-
ing metals, conductive dust can settle in the interior of the
power tool. The total insulation of the power tool can be im-
paired.
If the machine should fail despite the care taken in manufac-
turing and testing procedures, repair should be carried out by
an after-sales service centre for Bosch power tools.
In all correspondence and spare parts order, please always in-
clude the 10-digit article number given on the type plate of
the machine.
