6 Operation

CAUTION
The tool may get hot during use. Wear protective gloves.
CAUTION
The power tool may suddenly swing to the side (rotate about its own
en
axis) when drilling, hammer drilling or screwdriving. Always use the
power tool with the side handle fitted and hold it securely with both
hands.
CAUTION
To avoid injuries caused by the insert tool, wear protective gloves when
changing insert tools.
6.1 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.
6.2 Speed selection using the 2-speed gear switch
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 mechanical 2-speed gear switch can be used to select the speed range
required. Speed with a fully-charged battery: 1st gear: 0-370 /min or 2nd
gear: 0­2140 /min.
6.3 Switching on / off
Speed of rotation can be controlled smoothly up to maximum speed by
pressing the control switch slowly.
6.4 Fitting the drill bit
NOTE
The connection end of the insert tool must be clean and lightly greased. Use
Hilti grease as it is compatible with the tool's sealing system.
