GARAGE DOOR MAINTENANCE

SECTION 12

12.2 MONTHLY TESTS

12.1 MONTHLY INSPECTION

Every month, carry out the following inspection

and tests on your garage door.

1) Uncouple the "pro-alpha" door operator

from the garage door.

2) Make sure that the area around the door is

clear of persons and obstructions.

3) Lift the door by hand from the "fully

closed" position to the "full open"

position. Make sure that the door moves

freely throughout the cycle without

jamming or binding at any point along it's

path.

4) Raise the door to the "half open" position.

If the door is correctly balanced it should be

able to remain in that position without any

assistance.

5) If raised any higher, it should tend to rise

very slowly without assistance and remain

in the "full open" position.

6) Below the "half open" position, it should

tend to close slowly.

7) From the "fully closed" position, the door

should not require more than

approximately 10 kg of force to raise the

door to the "open" position, regardless of

the size of the door.

Open and close the door manually, making sure

that it functions normally. If the door jams up or is

difficult to open and close, then proceed follows:-

1) Inspect the door for signs of worn or

damaged parts. Look for loose or missing

fasteners. Make sure that all screws and

fasteners are secure.

2) Check for worn or damaged hinges,

rollers, pulley wheels, cables and springs

and repair / replace as necessary. The

failure of any one of these components can

cause the door to malfunction.

3) Apply a suitable lubricant to all the moving

parts of the door especially pivot-pins,

hinges, rollers and bearings.

INSPECT YOUR GARAGE DOOR.

To ensure that your "pro-alpha" door operator

functions properly, make sure that the garage

door itself is in good working order. This is the

secret to having a reliable automatic garage

door. The door operator is not designed to

overcome the problems of a door which is in a

state of disrepair.

Damaged or worn-out components and

doors must be serviced or replaced!!!

Consult your "pro-alpha" dealer for advice.
