TRACK ASSEMBLY
1. Using the 3/8"-16 x 3/4" bolts and flange hex nuts provided,
assemble the operator track by installing and tightening the
track spacer brackets. Position the spacers evenly over the
length of the track.
NOTE:
The nylon pad on the spacer
bracket should face up.
2. Using (2) 3/8"-16 x 1" bolts and lock washers, install the front
idler assembly to the second set of holes of one end of the
track. Refer to the illustration below.
3. Slide the trolley carriage onto the track so that the hole of the
door arm faces the front (towards door).
POWERHEAD ATTACHMENT
1. Position the track assembly on the frame of the powerhead so
that the motor side of operator is in back (away from door ).
2. Using (2) 3/8"-16 x 3/4" bolts and flange hex nuts, install the
front idler assembly to the second set of holes of one end of
the track. Be sure the take-up bolt faces toward end of track.
Refer to the illustration below.
3. Connect the track to the operator by fastening (2)
3/8"-16 x 3/4" bolts and nuts through the frame and the end
holes in track. Tighten all four bolts to secure the track to the
powerhead.
TROLLEY CARRIAGE / CHAIN ATTACHMENT
1. Uncoil the chain and run it up through the idler on the chain
take-up assembly. Pull it towards the operator running it over
the nylon spacer brackets and over the top of the trolley
carriage. Pull the chain around the final drive sprocket on the
operator and back toward the trolley carriage. Pull the release
clip on the carriage and push one end of the chain through the
chain slot (see illustration). Using one of the masterlinks,
connect the drive link to one end of the chain. Pull the drive
link toward the free end of the chain and determine where to
cut chain for proper adjustment. Be sure the chain tensioning
bolt is loose before removing links. Using the other masterlink
fasten the adjusted chain to the free end of the drive link.
2. Slide the trolley carriage back and forth past the drive link to
assure that there will be no binding. Turn the chain tensioner
adjustment bolt to take out most of the chain lack.
• With trolley positioned at either end of the track, a properly
adjusted chain will sag about 3" (7.62 cm) at the midpoint. If
necessary, remove links from the chain to achieve proper
adjustment.
3. Tie the release cord to the trolley carriage.
