Residual risks
Even if you use this electric power tool in
accordance with instructions, certain residual
risks cannot be rules out. The following hazards
may arise in connection with the equipment's
construction and layout:
1. Lung damage if no suitable protective dust mask
is used.
2. Damage to hearing if no suitable ear protection is
used.
3. Health damage caused by hand-arm vibrations if
the equipment is used over a prolonged period or
is not properly guided and maintained.

6. Before starting the equipment

Before you connect the equipment to the mains
supply make sure that the data on the rating plate
are identical to the mains data.
Always pull the power plug before making
adjustments to the equipment.
Check the drilling point for concealed electrical
cables, gas and water pipes using a cable/pipe
detector.
6.1 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
better stability whilst using the hammer drill. The
machine must not be used without the additional
handle (6) for safety reasons.
The additional handle (6) is secured to the hammer
drill by a clamp.
Slacken the clamping screw (10).
n
Slide the additional handle (6) over the chuck and
n
turn to the desired position.
Retighten the clamping screw (10) in order to lock
n
the additional handle (6) into this position.
6.2 Depth stop (Fig. 3 – Item 7)
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
n
stop (7).
Set the depth stop (7) to the same level as the
n
drill bit.
Pull the depth stop (7) back by the required
n
drilling depth.
Retighten the locking screw (10).
n
Now drill the hole until the depth stop (7) touches
n
the workpiece.

6.3. Tool insertion (Fig. 4)
Clean the tool before insertion and apply a thin
n
coating of drill bit grease to the shaft of the tool.
Pull back and hold the locking sleeve (2).
n
Insert the dust-free tool into the tool mounting as
n
far as it will go whilst turning it. The tool will lock
itself.
Check that it is properly secure by pulling the
n
tool.
6.4. Tool removal (Fig. 5)
Pull back and hold the locking sleeve (2) and remove
the tool.
7. Starting up
Important.
To prevent all danger, the machine must only be
held using the two handles (5 / 6). Otherwise there
may be a risk of suffering an electric shock if you drill
into cables.
7.1 ON/OFF switch (Fig. 6/Item 4)
To switch on:
Press the ON/OFF switch (4)
Continuous operation:
Secure the ON/OFF switch (4) with the locking
button (8).
Important. It may only be locked if the drill is set to
rotate clockwise.
To switch off:
Press the ON/OFF switch (4) briefly.
7.2 Adjusting the speed (Fig. 6/Item 4)
You can infinitely vary the speed whilst using the
n
tool.
Select the speed by applying a greater or lesser
n
pressure to the ON/OFF switch (4).
Select the correct speed: The most suitable
n
speed depends on the workpiece, the type of use
and the drill bit used.
Low pressure on the ON/OFF switch (4): Lower
n
speed
Greater pressure on the ON/OFF switch (4):
n
Higher speed
Tip: Start drilling holes at low speed. Then increase
the speed in stages.
