ON/OFF switch
A start-up protection is linked with the ON/OFF switch. This start-up protection
has the effect that the percussion rate or speed of the rotary hammer rises slowly
after pressing the ON/OFF switch. The start-up protection prevents or reduces
the chisel from slipping or the drill from jamming.
Thumbwheel for pre-selecting speed
Use the thumbwheel to pre-select the speed.
Reducing the speed while in percussion operating mode diminishes the percus-
sion forces as required for removing tiles, for example.
Adjusting lever for chiseling/hammer drilling
The adjusting lever for chiseling/hammer drilling has three positions as listed be-
low. The arrow on the housing and the opposite symbol on the adjusting lever
indicate the selected operating mode.
While in operating mode "Positioning," it is possible to turn a flat chisel by hand
to achieve the correct working position.
