Speed preselection (GWX 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 (27) lights up white. When a speed value is programmed individually, the speed level/mode indicator
(27) 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min
-1
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.
