limits. The need for occasional adjustment for the force
and limit settings is normal. Weather conditions in
particular can affect door travel.

• Manually check door for balance or any binding

problems.

6. My motor unit hums briefly:

• First verify that the trolley is against the stop bolt.

• Release the door from the opener by pulling the

Emergency Release Rope.

• Manually bring the door to a closed position.

• Loosen the chain by adjusting the 

outer nut

4 to 5

turns. This relieves the tension.

• Run the motor unit from the remote control or door

control. The trolley should travel towards the door and
stop. If the trolley re-engages with the door, pull the
Emergency Release Rope to disengage.

• Decrease the UP travel by turning the UP Travel

adjustment screw 2 full turns

away 

from the arrow.

• Re-tighten the outer nut so the chain is a 1/2" (13 mm)

above the base of the rail. (When the door is
reconnected and closed, the chain will sag. This is
normal.)

• If the trolley does not move away from the bolt, repeat

the steps above.
