Incorrectly seated pin.

NOTE: Rail comes fully preassembled with straight door

arm already attached.

■ Unpack one-piece preassembled rail.

■ Leave straight door arm taped inside rail for safe and

convenient installation—it will be untaped and used later.

■ Position door opener head with control panel facing front

of garage. Rest opener head on cardboard or protective

surface on floor so opener does not get scratched. Chassis

■ Position rail onto opener chassis by lining up rail sprocket

opening with motor head shaft (Fig. 17A). Make sure shaft

engages teeth inside rail sprocket. Press rail down firmly

onto shaft and opener chassis. DO NOT HAMMER.

■ Position 2 "C" brackets over rail and onto chassis. Flanges

on "C" brackets must fit into cutout area on chassis (Fig.

17B).

■ Insert screws 6 x 14 through bracket holes and into chassis

holes, and tighten screws firmly to hold rail to head (Fig.

17C).

■ For sectional doors, proceed to step 8-5.

ADDITIONAL STEP FOR ONE-PIECE

DOORS ONLY:

IMPORTANT NOTE: For installation on One-Piece Doors

only, the straight door arm that is factory installed

onto the rail must be replaced by the curved door

arm supplied as part of hardware in powerhead box.

This must be done after attaching rail to powerhead,

before moving to step 8-5.

■ Turn rail and opener head over so that open channel in

rail faces up.

■ Untape straight door arm that is secured inside rail.

■ Remove and save the two phillips head screws that are

securing the door arm pin and straight door arm (Fig. 18).

■ Lift arm and pin straight out of slot in trolley, and remove

pin from straight door arm.

■ Insert pin into short side of curved door arm as shown.

■ Orient arm so that long side extends away from trolley.

■ Carefully insert pin and door arm into slot in trolley.

Push pin into slot with door arm so pin is fully seated into

trolley slot. IMPORTANT: Pin must be straight and seated

properly into recessed area in trolley. See Fig. 18A.

■ Secure pin and curved arm with the two phillips screws

which were removed from trolley—DO NOT use any

other screws. Tighten screws firmly.

■ Turn rail and powerhead over so that open channel

in rail faces down. Now proceed to Step 8-5.
