Manual disengagement
The opener is equipped with a manual release cord to disengage shuttle and move door by hand while holding
the handle down (Fig. 11). Pull on the handle to disengage the shuttle.
To re-engage the door set the shuttle catch into the original position and simply run opener in automatic mode or
move door by hand until the trolley engages in the chain shuttle.
In some situations that a pedestrian door or other entry to the garage is not in state, it is recommended that an
external disengagement device should be fitted (Fig. 12).

Maintenance
No particular maintenance is required for the logic circuit board. Check the door at least twice a year if it is properly
balanced, and all working parts are in good working condition or not. Check the reversing sensitivity at least twice
a year, and adjust if it is necessary. Make sure that the safety devices are working effectively (photo beams, etc.)
Notice: A rude operating door can affect the life of the automatic opener due to incorrect loads, and will
void the warranty.
