Manual operation
In case the energy supply fails, or when in-
stalling and adjusting the actuator, the actua-
tor stem can be "retracted or extended" ma-
nually
Use the disengaging stem to unlock the motor
and actuator stem and move the stem using
the side-mounted handwheel.
– If the actuator is installed vertically, push
down the disengaging stem in the direction
of the extending actuator stem.
– Turn the handwheel alternately counter-
clockwise/clockwise, until it engages no-
ticeably.
– If the direction of rotation is clockwise, the
actuator stem extends.
If the direction of rotation is counterclock-
wise, the actuator stem retracts.
The linear actuator then switches automat-
ically back to motor operation as soon as you
release the disengaging stem.

Manual operation
CAUTION!
Do not operate the handwheel when
the motor is in motion.
Do
not
override the adjusted travel
range with the handwheel. Observe
the rated travel, otherwise the actua-
tor could be damaged. This applies
especially to an uninstalled actuator
.
