6. Operation
6.1 ON/OFF switch (Fig. 6/Item 5)
First fit a suitable drill bit into the tool (see 5.3).
Connect the mains plug to a suitable socket.
Position the drill in the position you wish to drill.
To switch on:
Press the ON/OFF switch (5)
Continuous operation:
Secure the ON/OFF switch (5) with the locking
button (4).
To switch off:
Press the ON/OFF switch (5) briefly.
6.2 Adjusting the speed (Fig. 6/Item 5)
You can infinitely vary the speed whilst using the
tool.
Select the speed by applying a greater or lesser
pressure to the ON/OFF switch (5).
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): Lower
speed (suitable for: small screws and soft
materials)
Greater pressure on the ON/OFF switch (5):
Higher speed (suitable for large/long screws and
hard materials)
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).
6.3 Preselecting the speed (Fig. 6/Item 6)
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.
Set the speed using the setting ring (6) on the
ON/OFF switch (5).
Do not attempt to make this setting whilst the drill
is in use.

6.6 Tips for working with your hammer drill
6.6.1 Drilling concrete and masonry
Switch the Drill/Hammer drill selector switch (3)
to position B (Hammer drill).
Always use carbide drill bits and a high speed
setting for drilling into masonry and concrete.
6.6.2 Drilling steel
Switch the drill / hammer drill selector switch (3)
to position A (drill).
Always use HSS drill bits (HSS = high speed
steel) and a low speed setting for drilling steel.
We recommend that you lubricate the hole with a
suitable cutting fluid to prevent unnecessary drill
bit wear.
6.6.3 Inserting/Removing screws
Switch the Drill/Hammer drill selector switch (3)
to position A (drill).
Use a low speed setting
6.6.4 Starting holes
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.
