To check spring tension: Open the door halfway. The springs should hold the door in this position. Should the door slide down or raise on its own,
contact a authorized, qualified door system service representative to adjust the spring tension.
Fixing points:
Check all fixing points, ensuring that they are firmly secured. Tighten any loose screws and/or bolts.
Track rollers and door track:
The door should open and close smoothly. Ensure the door rollers are rotating freely when opening and closing the door. Should the rollers not turn
easily or not turn at all: Clean the door track, removing dirt and any foreign substances. Clean and lubricate rollers inside of roller guides. Do not
lubricate the door track.
To dismantle the installed garage door system, remove the garage door system in the reverse order in which it was installed in the installation section of
this manual. Check local codes for proper discardment.
