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.
