Manual disengagement
The opener is equipped with a manual release cord to disengage shuttle and move door by
hand while holding the handle down (Figure 23). Pull on the handle to disengage the shuttle.
To re-engage the door 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 is not in state, it is recommended that an external
disengagement device should be fitted (Figure 24).

Maintenance
1) 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.)
2) Light bulb replacing:
Notice: Make sure the power supply has been cut off before replacing the light bulb. And
ensure the voltage of the new light bulb is in accordance with the local voltage and the power
is within 25 Watt.
Demount the screws on the lamp cover. Take the lamp cover away then twist off the old L.E.D
light anti-clockwise. Fix the new L.E.D light and lamp cover.
Notice: A rude operating door can affect the life of the automatic opener due to incorrect loads,
and will avoid the warranty
