Reversing the Rotational Direction
Actuate the rotational direction switch 8
only when the machine is at a standstill.
The rotational direction switch 8 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 9 actuated.
Right Rotation: For drilling and driving in
screws, push the rotational direction switch 8
left to the stop.
Left Rotation: For loosening and unscrewing
screws and nuts, press the rotational direction
switch 8 through to the right stop.
Switching On and Off
To start the machine, press the On/Off switch 9
and keep it depressed.
To switch off the machine, release the On/Off
switch 9.
For low temperatures, the machine reaches the
full hammer/impact capacity only after a certain
time.
This start-up time can be shortened by striking
the inserted tool insert against the floor one
time.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on pow-
er tool can be variably adjusted, depending on
how far the On/Off switch 9 is pressed.
Light pressure on the On/Off switch 9 results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
