Connect Arm To Door And Trolley; Check Emergency Release - Genie M-4500 Owner's Manual

8-8. CONNECT ARM TO DOOR AND TROLLEY

I Make sure door is fully closed.
I Remove tape from rail holding straight door arm
(sectional door only) and allow door arm to hang freely.
I Pull the manual release cord on the trolley to disconnect
trolley from chain or belt connector. Slide trolley to posi-
tion it about 4" away from the door.
A. SECTIONAL DOORS:
I Position curved door arm into door bracket channel so
that short end of arm will be attached to door bracket.
See Fig. 25. Curved door arm should be attached roughly
at the same height as the top rollers of the door.
I Align curved door arm and bracket holes, then insert clevis
pin through holes. Attach cotter ring to hold pin in place.
I Align straight arm and curved arm. Position arms so that
at least two sets of holes line up. Select two overlapping
holes as far apart as possible and secure arms together
with hex bolts (5/16-18) and lock nuts.
B. ALL ONE-PIECE DOORS:
I Curved door arm should already be attached to trolley in
place of straight door arm. See Fig. 18, p. 10.
I Position free end of curved arm into door bracket slot.
Align curved door arm and bracket holes, then insert clevis
pin (5/16" dia.) through holes. Attach cotter ring to pin to
hold in place. See Fig. 26.
C. SECTIONAL AND ONE-PIECE DOORS:
I After connecting appropriate door arm, ensure trolley is
disengaged. Check for proper door operation by manually
lifting then lowering to fully opened and closed positions.
I Readjust door arm if needed.
PULL DOWN ON RELEASE KNOB TO LOCK TROLLEY,
THEN MOVE DOOR MANUALLY UNTIL TROLLEY LOCKS
WITH CONNECTOR INSIDE RAIL.

8-9. CHECK EMERGENCY RELEASE

Use extreme care when pulling release knob.
DO NOT use knob to pull door open or closed.
Except for emergency situations,
use knob only when door is closed.
The emergency release cord with red knob, which are
already attached to the trolley, are extremely important parts
of the opener system Fig. 27. Pulling the release cord disen-
gages the door from the opener. This allows the door to be
moved manually up and down independent of the opener
motor.
If the door is in the open position, use extreme care
when using the release.
Use emergency release to disconnect the door if the power
is out. It should also be used if for some unforeseen reason
the door strikes a person or object during its travel and does
not automatically reverse off the obstruction.
To release door—pull firmly down on red knob. (Fig. 27)
Prior to re-engaging door, ensure that all obstructions are
removed and door is operating properly manually. Before re-
engaging trolley with a chain or belt connector, pull down
knob again, then release. The red catch will stop in the
"lock" position (see Fig. 27A). Now the door can be recon-
nected by moving it manually and bringing it into position
when the connector is inside of the trolley.
