wherever possible.
6.2 Switching 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 Setting 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 materials)
Higher 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

6.6 Defining the speed range
(Figure 4)
앬
The speed selector switch (8) enables you to
work within a specific speed range.

6.7 Drill / Hammer drill selector switch
(Fig. 5)
앬
Use the Drill/Hammer drill selector switch (3) to
set whether you wish to drill or hammer drill.
6.8 Tips for working with your hammer drill
1. Drilling concrete and masonry
앬
Switch the Drill/Hammer drill selector switch (3)
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 (3)
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.
