Normally, very little maintenance is required. A monthly visual inspection must be made for
loose or missing hardware and for excessive slack in the v-belt and jackshaft chain. The
clutch must be checked periodically and adjustments made if necessary. (See page 14)
Test the reversing edge circuit or components (where applicable) at least once a month by
permitting the door to contact an obstruction while closing.
Lubrication of the operator is not required. It is important, for trouble free service from the
operator, that the door be kept free from binding, properly counter balanced and periodically
lubricated. An annual inspection of the door by a qualified overhead door professional
is recommended.
* Door must be in good operating condition. An electrical door operator cannot move a garage
door that is in poor condition. The door must operate freely in the track, with no binding or
obstructions, and must be well balanced. Check the spring balance of your door by bringing
the door to a half-open position and leaving it there. If the door stays in that position, it is well
balanced. If it moves more than a few inches the springs possibly need adjustment. Call a
qualified door service company.
Warning: Repairs and adjustments to the door and operator should be
performed only by someone qualified to service commercial overhead
doors and operators.
We constantly strive to maintain and improve the quality of our products. Therefore, the
