6.1 Additional handle
WARNING
Operate the machine only with the
additional handle. Loss of control can
cause personal injury.
Place the additional handle [1-8] in the
working position to provide a safe and fa-
tigue-free working situation.
Tighten the lower hand grip of the additional
handle [1-8] by turning in a clockwise direc-
tion. Turn the hand grip in an anticlockwise
direction to release it.
6.2 Depth stop
The required drilling depth can be set using
the depth stop [1-9].
Release the additional handle [1-8] and in-
sert the depth stop [1-9] into the additional
handle.
Extend the depth stop [1-9] until the dis-
tance between the tip of the drill and the
tip of the depth stop [1-9] corresponds to
the required drilling depth.
6.3 Switching on/off
Press or release the on/off switch [1-5].
The on/off switch can be locked on with
the locking button [1-6]. To release, briefl y
press and release the on/off switch [1-5].
6.4 Speed control
With the on/off switch [1-5], the speed can
be continuously varied. With light pressure
on the on/off switch [1-5], the machine be-
gins to rotate slowly; with increased pres-
sure, the speed increases.
Always match the speed setting to the ma-
terial concerned and the diameter of the
drill bit.
6.5 Rotational direction
switching
Operate the rotational direction switch [1-7]
only when the machine is at a standstill!
Take hold of the rotational direction switch
[1-7] on both sides.
Clockwise rotation:
For drilling and fi xing screws.
Anticlockwise rotation:
For loosening and removing screws
and nuts.
Important: Press the rotational direction
switch [1-7] up to the stop on the housing,
i. e. until it snaps in audibly. If the rotational
direction switch [1-7] is set between the
positions “R” and “L”, the machine cannot
be switched on.
6.6 Selecting the modes
of operation
The operational mode switch [2-1] can be
used to select the required settings – fi gure
[2].
The switchover can be performed best at
standstill.
After the On/Off switch [1-5] has been actu-
ated and the machine has started, the gear-
box switches to the preselected setting.
a) Impact drilling
CAUTION
Wear protective glasses and hearing
protection.
► Left rotation when impact drilling damag-
es the drill. Switch off the impact mecha-
nism for diamond crown drilling or for
mixing work.
► When hammer drilling, only use drills with
tungsten carbide inserts and SDS-Plus
shafts.
WARNING
Do not use chucks for impact drilling
– you could damage them!
Drilling in tiles
Start drilling slowly on the tile. Only after the
tile is drilled through, switch to impact drill-
ing. This prevents the tile from cracking.
b) Drilling / Stirring / Screwing
Drilling with diamond drill bits
Switch the hammer action off when drilling
with a diamond drill bit.
Set the operation mode switch [2-1] to
drilling.
