detector.
5.1 Additional handle (Fig. 2 – Item 6)
For safety reasons you must only use the
hammer drill with the additional handle.
The additional handle (6) enables you to achieve

turn to the desired position.
Retighten the clamping screw (10) in order to lock
the additional handle (6) into this position.

The depth stop (7) is held in place with the locking
screw (10) on the additional handle (6) by means of
a clamp.
Undo the locking screw (10) and fit the depth
stop (7).
Set the depth stop (7) to the same level as the
drill bit.
Pull the depth stop (7) back by the required
drilling depth.
Retighten the locking screw (10).
Now drill the hole until the depth stop (7) touches
the workpiece.

speed depends on the workpiece, the type of use
and the drill bit used.
Low pressure on the ON/OFF switch (4): Lower
speed
Greater pressure on the ON/OFF switch (4):
Higher speed
Tip: Start drilling holes at low speed. Then increase
the speed in stages.
Benefits:
The drill bit is easier to control when starting the
hole and will not slide away.
