damaged, run untrue or vibrate during use. Damaged
abrasive tools can burst apart and cause injuries.
Kickback stop
If there is a sudden kickback in the power tool,
e.g. jamming in a separating cut, the power
supply to the motor will be interrupted elec-
tronically. The kickback stop indicator(32)
then lights up. When kickback stop is activ-
ated, the status indicator (36) flashes red.
To restart the tool, set the on/off switch (5) to the off posi-
tion and then switch the power tool on again.
Restart protection
The restart protection feature prevents the power tool from
starting unintentionally after the power supply to it has been
interrupted.
Speed Preselection (GWS 18V-15 SC)
In the default setting, 3 speed levels are preset. A special application (Bosch Toolbox App) can be used to program up to 6
speed levels.
If the number of speed levels is changed, the values of the individual levels are adjusted by default. In this case, the speed
level/mode indicator (34) lights up white. When a speed value is programmed individually, the speed level/mode indicator
(34) lights up blue at this speed level (i.e. not according to a default setting). The individual adaptation of speed levels is pos-
sible in steps of 200 rpm each. Observe the ascending logic of the steps (2 ≥ 1 / 3 ≥ 2 etc).
The information in the tables below describes the preset speeds (default settings) for each programmed number of levels.

Bosch Power Tools
When restart protection is activated, the status indicator
(36) flashes red.
To restart the tool, set the on/off switch (5) to the off posi-
tion and then switch the power tool on again.
Impact shutdown
The integrated impact shutdown switches the power tool off
as soon as it hits the floor. The status indicator (36) then
flashes red.
To restart the tool, set the on/off switch (5) to the off posi-
tion and then switch the power tool on again.
User interface (see figure D)
The user interface (4) is used to preselect the speed and to
indicate the status of the power tool.
