6.2 Adjusting the speed (Fig. 11/Item 5)
You can infi nitely vary the speed whilst using the
tool.
•
Select the speed by applying a greater or les-
ser 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): Lo-
wer 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 increa-
se the speed in stages.
Benefi ts:
•
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. 12/Item 6)
The speed controller (6) enables you to defi ne the
maximum speed.
•
Set the speed controller (6) to the required
position.
•
With the On/Off switch (5) pressed right in,
the motor will now run as quickly as was set
at the speed controller (6).
•
The setting can also be made during opera-
tion.
Constant electronics

With constant electronics, the set speed is kept
constant even when the tool is working under
load.
