1.
Disconnect the screwdriver from the air supply.

pull off the reduction gear carefully, until one slot on its housing and one
slot on the motor housing of the screwdriver becomes visible.

Push the supplied hand screwdriver 326240 through the slot on the mo-
tor housing into the half-round bore of the lock ring (if necessary, turn bit
by hand).

By turning the hand screwdriver clockwise (-), the torque is reduced and
by turning it counter-clockwise (+), the torque is increased.
