Switching the gear setting
(figure 14).
With the gear switch, you can select the
speed and thus the torque.
Adjust the gear setting only when the
machine is at a complete stop or when the
motor is running down.
Set the switch to gear 1 to work at low
speed with high torque. This setting is suit-
able for drilling with large drill bit diameters
and for tapping.
Set the switch to gear 2 to work at high
speed with low torque. This setting is suit-
able for drilling with small drill bit diameters.
