INDEX
The J4C has 2 operang modes, automac and manual, the required mode is selected by using a
lever on the lower half of the actuator housing (Fig 7).
The 2 posions are marked:
AUTO = Automac operaon
MAN = Manual operaon
Warning: Do not remove the selector lever securing screw, as this will allow its internal mechanism
to become loose and will cause irreparable damage to the actuator’s gearbox.
Removing this screw will invalidate the warranty.
When “AUTO” posion is selected:
The hand wheel, of models 20,35,55, and 85 rotates automacally, it is very important not to block
it, otherwise the actuator could suffer unrepairable damages.
