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 drawbar chain. The clutch
must be tested periodically and adjustments made if necessary
(see page 15). The brake (where applicable) is adjusted at the
factory and will need periodic adjustment for wear. When
adjustment becomes necessary see Figure 19 on page 16 for
the adjustment procedure.
Test the reversing edge circuit at least once a month by
permitting the door to contact an obstruction while closing. To
test a pneumatic or foam door edge for proper reversal, place an
object beneath the leading edge of the door. To test a
photoelectric device for proper reversal, start the door down
and obstruct the beam. The door should instantly reverse when
it comes into contact with the object provided the height of the
object exceeds the cut out point built into the close limit switch
(approx. four (4) inches).
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.
Warning: Repairs and adjustments to the door and operator
should be performed only by someone qualified to service
commercial overhead doors and operators.
