Selecting the rotation direction
(figure 12).
To avoid accidental starting, e. g., during
transport, set the rotation selector switch to
the centre position.
Set the rotation selector switch to right or left
rotation as required.
Adjust the rotation selector switch only
when the machine is at a complete stop.
Adjusting the gear setting
(ASB18 Q (**), ABS 18Q (**))
(figure 13).
Adjust gear setting 1 to work with low speed
and high torque. This gear setting is suitable
for drilling with large drill bit diameters.
Adjust gear setting 2 to work with high speed
and a lower torque. This setting is suitable for
drilling with small drill bit diameters.
The material-dependent gear setting can be
determined by practical testing.
Always slide the gear selector to the stop.
Otherwise, the machine can become dam-
aged.
Adjust the rotation direction only when
the machine is at a complete stop.
