Checking The Amount Of Force

Required To Lift The Garage Door

Check the balance of the door as shown below.

1) Place a bathroom scale under the door.

2) With the operator disconnected, note the

reading on the scale. A well balanced door

should show a reading of not more than 15kg.

If the door does not pass the inspection,

.......... call in the services of a professional

door mechanic to repair it for you.

When servicing a Tip-Up garage door, pay

carefull attention to the main Pivot Pin

Bearings. These parts are subjected to high

loads and must be lubricated regularly.

Damaged bearings and bushes must be

replaced immediately as these components

bear the full weight of the door and should they

fail they would pose a great danger to persons

and property.

12.5 ROLL-UP DOOR MAINTENANCE

Generally, Steel Roll-Up doors require very

little maintenance. Make sure that the guide

channels (tracks) are kept clean.

Do not put grease or silicon based

lubricants in the guide channels.

If lubrication is required, use a "Dry

Graphite Stick", "Graphite Powder"

or "Graphite Spray".

Alternatively, a very light, “silicon-

free” oil or “Teflon” lubricant.

A heavy grease tends to collect dirt and grit

which compounds the problem of excessive

friction between the door curtain and the guide

channels.

THE SPRINGS OF YOUR GARAGE DOOR

ARE UNDER A GREAT DEAL OF

TENSION.

DO NOT ATTEMPT TO MAKE ANY

ADJUSTMENTS TO THEM WITHOUT

HAVING THE PROPER TOOLS OR

KNOW-HOW.

SERIOUS OR EVEN FATAL INJURIES

MAY BE SUSTAINED IF THE REPAIRS

ARE NOT CARRIED OUT CORRECTLY!!!

CAUTION! CAUTION!
