10.8 Setting the drilling speed (fig. 1)
The correct speed must be set to suit the workpiece to be drilled
and the tool diameter.
Mechanical gear selection:
Two different speed ranges can be selected with the gear selec-
tor switch (18).
Gear 1: Low speeds (170- 880 min
Gear 2: High speeds (490-2600 min
eters.
m Attention: Actuate the gear selector switch (18) only

latch into place turn the chuck (14) a little.
If the gear selector switch (18) cannot be turned as far as the
stop, turn the chuck a little with the drill.
Electronic speed control:
The speed of the individual gears can be seamlessly adjusted
with the electronic speed control:
Set the speed with the help of the speed control (12).
The current speed can be seen on the display (9).
