WARNING: The limit microswitches must be switched when the window is closed. To be sure of that, carry out the
adjustment on the tie-rod (7) only after feeding the operator in order to pull the chains completely back.
The actuator is electronically protected against immediate overload. To guarantee a good lasting performance of the actuator,
do not use this protection as an alternative to the limit microswitches.
