7 Operation

CAUTION
The tool may get hot during use. Wear protective gloves.
CAUTION
When drilling and screwdriving, the grip of the tool may be deflected
laterally (the tool tends to pivot about its own axis).
CAUTION
To avoid injuries caused by the insert tool, wear protective gloves when
changing insert tools.
7.1 Setting forward or reverse rotation
NOTE
The forward / reverse switch is used to select the direction of rotation of the
drive spindle. An interlock prevents switching while the motor is running.
The control switch is locked when the forward / reverse switch is in the
middle position. Push the forward / reverse switch to the left (when the
power tool is held in the working direction) to select forward rotation. Push
the forward / reverse switch to the right (when the power tool is held in the
working direction) to select reverse rotation.
7.2 Selecting the speed range
WARNING
Large and heavy insert tools must only be operated in first gear. There
is otherwise a risk that the tool will be damaged when it is switched off or,
under unfavorable conditions, the chuck might be detached.
NOTE
The gear selector switch can be used to select the speed range. Speed range
for the SF 2-A/SFD 2-A with a fully charged battery: 1st gear: 0­400/min,
2nd gear: 0­1500/min.
NOTE
The gear selector switch can be operated only when the motor is at a
standstill.
