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

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

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.
Screwing
The screw adapter [3-2] (accessory) can
hold screw bits.
Commercially available bits with a hexago-
nal dimension of 6.3 mm or 1/4" (DIN 3126,
Form C) can be used. The screw-bits are
held in the adapter with a spring ring.
Therefore, use only bits with a notch.
Set the operation mode switch [2-1] to
drilling.
