6.2 Switch the tool on and off
(Figure 3)
앬
First fit a suitable drill bit into the tool (see pre-
vious section).
앬
Connect the mains plug to a suitable socket.
앬
Position the drill in the position you wish to drill.
앬
Only then should you switch on the machine:
Press and hold the ON/OFF switch (5)
-> the drill will start.
Release the ON/OFF switch (5)
-> the drill will stop.
앬
Continuous operation:
If you wish to use the
hammer drill permanently, press the locking but-
ton (4) after pressing and holding the ON/OFF
switch (5).
Deactivate continuous operation:
Press the
ON/OFF switch (5) in fully; this will release the
locking button (4).
6.3 Set the speed
(Figure 3)
앬
You can infinitely vary the speed whilst using the
tool.
앬
Select the correct speed:
The most suitable
speed depends on the workpiece, the type of use
and the drill bit used.
Low pressure on the ON/OFF switch (5): Low
speed (suitable for small screws and soft materi-
als)
Greater pressure on the ON/OFF switch (5):
Higher speed (suitable for large/long screws and
hard materials)
앬
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.
- You avoid drilling messy holes (for example in
tiles).
6.4 Preselecting the speed
(Figure 3)
앬
The speed setting ring (6) enables you to define
the maximum speed. The ON/OFF switch (5) can
only be pressed to the defined maximum speed
setting.
앬
Set the speed using the setting ring (6) and the
arrow on the ON/OFF switch (5).
앬
Do not attempt to make this setting whilst the drill
is in use.
6.5 Selecting the direction: Clockwise/Counter-
clockwise

6.7 Tips for working with your hammer drill
1. Drilling concrete and masonry
앬
Switch the Drill/Hammer drill selector switch (2)
to the hammer symbol position.
앬
Always use carbide drill bits and a high speed
setting for drilling into masonry and concrete.
2. Drilling steel
앬
Switch the Drill/Hammer drill selector switch (2)
to the drill symbol position.
앬
Always use HSS drill bits for drilling into steel
(HSS: high speed steel) together with a low tor-
que setting.
3. Inserting/Removing screws
앬
Switch the Drill/Hammer drill selector switch (2)
to the drill symbol position.
앬
Use a low speed setting
4. Start drilling holes
앬
If you wish to drill a deep hole in a hard material
(such as steel), we recommend that you start the
hole with a smaller drill bit.
5. Drilling into tiles
