The SR38/68/75 are fitted with a 3-speed gear box. Besides the three gear speeds, the motor can
additionally be operated in different speeds. Thus the different speeds according to the table below can
be selected.
The speeds of the SR25/65 are only changed via the motor, thereby six motor speeds can be chosen,
which can also be changed while drilling.
