WARNING:
Always wear eye protection with side shields marked
to comply with ANSI Z87.1 when assembling and
performing maintenance on this product. Failure to do
so could result in objects being thrown into your eyes
resulting in possible serious injury.
NOTICE:
Many of the illustrations in this manual show only portions
of the garage door opener. This is intentional so that we
can clearly show points being made in the illustration.
Never operate the garage door opener without all parts
securely in place and in good operating condition.
WARNING:
Confirm that the inner trolley is in the orientation shown
in Figure 10. An incorrectly installed Inner Trolley could
result in the garage door opener operating in the opposite
direction from its intended movement and result in death
or serious personal injury from the moving garage door.

 Remove tie wrap from rail and pulley.
 Pull the front pulley and belt through the end rail and into
a sleeve.
 Slide the outer trolley into the end rail.
 Pull the release lever down and move outer trolley toward
the inner trolley until they are engaged.
NOTE: When lowered, the release lever should point
away from the front pulley and toward the inner trolley
as shown in figure 10. If the release lever points in the
opposite direction, remove and reinstall the outer trolley.
 Insert the edge of the end rail into the sleeve. Slide
together until rail clicks in place. If you cannot get the rail
to fit by hand, try gently tapping it with a rubber mallet
until it is snug and clicks into place. Be careful not to
pinch or damage the belt.
