NOTE:
The Rail/
Chain Assembly is
packaged separately from
the
Power Head Unit. The trolley, front idler/tension
adjustment assembly, chain, drive gear and limit cams
are assembled to the Rail/Chain Assembly at the
factory. Follow the steps outlined below to complete
assembly prior to installation. Refer to the component
identification illustrations on the previous page.
STEP 1:
Prior to attaching the motor drive unit to the
rail assembly, the Open and Close adjustment bolts
must be installed. Place the threaded end of the
adjustment bolt through the hole in the rail and then
slip the head of the bolt through the center of the
double key hole. Slide the spring over the bolt and
attach load adjusting nut. Tighten until the tip of the
bolt extends 3/16” outside the nut. Repeat above for
the other side.

STEP 2:
Protect the Power Unit cover from
scratching during assembly by placing it on cardboard.
Loosen the two 5/16" lock washer nuts on top of the
power head drive unit.
STEP 3:
VERY IMPORTANT !
Position a paper
shim around the power head unit drive gear (standard
weight paper, see illustration). Shim must remain in
place while assembling the power head unit to the
Rail/Chain assembly to ensure a proper gear mesh and
avoid excessive long term wear.
STEP 4:
Align the four key holes in the Rail/Chain
assembly with the two front guide tabs and the two
rear bolt studs on the power head unit and place the
rail/chain assembly in place over the power head unit.
