OPERATION AND ADJUSTMENT INSTRUCTIONS
23
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 chain.
The clutch must be checked periodically
and adjustments made if necessary. (See
page 16)
Test the reversing edge circuit or
components (where applicable) at least
once a month by permitting the door to
contact an obstruction while closing. (See
Testing Section. )
Door must be in good operating condition.
An electrical door operator cannot move a
garage door that is in poor condition.
It is important, for trouble free service from
the operator, that the door be properly
maintained, kept free from binding, and
periodically lubricated.
MAINTENANCE
An annual inspection of the door by a
qualified overhead door professional is
recommended.
W a r n i n g : R e p a i r s a n d
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 components shown in the
illustrations were accurate at time of
printing but are subject to change
without notice as quality improvements
are made.
