position.
Hammer drilling
•
For hammer drilling in masonry and
concrete, set the operating mode selector (4)
to the position
•
When hammering, the tool should not
bounce and run smoothly. If necessary,
increase the speed.
Hammering
•
For hammering with spindle lock, and for
light chiselling and chipping, set the
operating mode selector (4) to the position.
•
Make sure the forward/reverse switch is in
the forward position.

chiselling, turn the chisel to the desired
position. If resistance is felt during mode
change, slightly turn the chisel to engage the
spindle lock.
•
When hammering with spindle lock, the
angle of the bit may be changed. Set the
operating mode selector (4) to the
position, the angle of the bit may now be
changed by rotating the tool holder (6). Set
the operating mode selector (4) to the

Selecting the direction of
rotation
For drilling, for tightening screws and for
chiselling, use forward (clockwise) rotation. For
loosening screws or removing a jammed drill bit,
use reverse (counterclockwise) rotation.

Switching on and off
•
To switch the tool on, press the variable
speed switch (1). The tool speed depends on

For continuous operation, press the lock-on
button (2) and release the variable speed
switch. This option is available only in forward
(clockwise) rotation.

To switch the tool off, release the variable
speed switch. To switch the tool off when in
continuous operation, press the variable
speed switch once more and release it.
