Mechanical gear selection (option)
The gear selection / rotation stop switch III can be
used to select three settings.
GB
1 Low speed range: Hammer drilling,
drilling with normal twist drills in
wood/metal over 8 mm, and stirring
tasks
2 High speed range: Drilling with nor-
mal twist drills up to 8 mm
No rotational motion: Light chisel
work
The switchover can best be performed at stand-
still. Please note that the gear selection / rotation
stop switch III can only be turned 1 level at a time.
After the On/Off switch V has been actuated and
the machine has started, the gearbox switches to
the preselected setting. Only then can the gear se-
lection / rotation stop switch III be turned to the
next setting.
Selecting the direction of rotation
Operate the rotational direction switch VII only
when the machine is at a standstill!
Grip the rotation direction changeover switch VII
on both sides and set the required direction of ro-
tation.
Clockwise rotation:
For drilling and fixing screws.
Anticlockwise rotation:
For loosening and removing screws
and nuts.
Important: Press the rotational direction switch
VII up to the stop on the housing, i. e. until it snaps
in audibly.
If the rotational direction switch VII is set between
the positions "R" and "L", the machine cannot be
switched on.
Selecting the modes of operation
The operational mode switch II can be used to se-
lect the required settings.
The switchover can be performed best at stand-
still.
After the On/Off switch V has been actuated and
the machine has started, the gearbox switches to
the preselected setting.

Impact drilling

Impact drilling
-NOTE-
Left rotation when impact drilling damages the
drill. Switch off the impact mechanism for diamond
crown drilling or for mixing work.
When hammer drilling, only use drills with tung-
sten carbide inserts and SDS-Plus shafts.
The use of commercially available rock drills with
cylindrical shafts by means of the adapter 6 and a
normal drill chuck in conjunction with the pneu-
matic impact mechanism is not possible.

Adjusting the chisel
Positioning the chisel
The chisel can now be turned by hand to the re-
quired working position.
The chisel latches automatically as soon as it is
radially loaded by the working or chiselling proc-
ess.
-NOTE-
In devices where the selection of the above sym-
bol is not available, put the operational mode
switch in an intermediate position.
Chiselling

-NOTE-
In some devices, the gear selector/rotation stop
