1. Check the metal track inside the four depots and check the mounting bracket that holds the track to the wall. If the bracket is loose, please tighten the bolts or screws. After closing the garage, check the interior of the garage to see if there is any depression in the track, and there is a bending place. If there are any damages, please hit them with a rubber hammer or a hammer padded with a piece of waste wood. If the track is seriously damaged, you will have to replace it.
2. Check the track
with a leveler to ensure that the track is on the same horizontal line and the horizontal track should tilt slightly toward the rear of the car. If the shutter door is rolled, the longitudinal part of the rail fatigue should be precisely perpendicular. On the wall of the garage, the two tracks must be at one height. If the tracks are not aligned properly, loosen the screws or bolts of the mounted brackets, but do not remove them, and then carefully tap the tracks to move them to the proper position. Check the tracks again with the level to make sure they are in the forward position and then tighten the screws or bolts on the mounted brackets.
3, use high concentration household cleaners to clean the track, remove dirt and hardened grease. Clean the torn bottom of the rotating shaft, then dry the track and the shaft.
4. Sprinkle the graphite powder on the track, spray the household lubricating oil or silicone resin on the shaft, or spray the special lubricating oil spray on the track and the shaft, to play a lubricating role. If there are pulleys, please lubricate it with the same lubricant on the shaft.
