Monthly maintenance

Manual release test
WARNING
An unbalanced door may fall down when re-
leased. Keep doorway free during test.
•
Close garage door, then pull down the red emergen-
cy release handle. The trolley will disconnect.
•
Test door for balance by releasing it at halfway. If
balanced, it should stay in place, supported entirely
by its springs. If the door falls down, seek profes-
sional garage door service.
Safety reversal test
•
With the door full open, place a board with a thick-
ness of 5 cm centered in the way of the door.
•
The closing door must reverse when it hits the
board. If door stops on the obstruction, seek profes-
sional garage door service.

Cleaning

•
If the garage door opener or the controls need
cleaning, wipe them with a brush or a soft damp
cloth. A mild detergent can be used but nothing like
alcohol, petrol or other cleaning agent.
•
Never use caustic agents to clean plastic parts.
