LiftMaster DUALAUXTROLLEY41 Manual Del Usuario

APPLICATION
This modification is available for all JDC and JHDC operators.
FUNCTIONS
This modification provides trolley type operation on wide standard lift
doors where a side mount operator is preferred over a draw bar operator.
NOTE: Use owner's manual for trolley installation, where appropriate, with
the following exceptions:
TRACK ASSEMBLY
1. Assemble both tracks by installing the track spacers (Figure 2).
2. Install the idler assemblies onto the wall end of the tracks. One idler
assembly is set up with a coupling sprocket on each end, and the other
idler is set up with only one coupling sprocket.
3. Slide the slider assembly into both tracks from the open end. Be sure
that the take-up bolt is facing the open end of the track.
4. Install the idler roller assemblies onto the open end of the tracks.
5. Install the chain, use the take-up bolt to adjust the chain tension to
allow about 3" sag in the center (remove chain and needed).
6. Determine which side of the door the operator will be mounted on and
install the track with the double idler on that side at the center of the
opening.
7. Install the track assembly with the single idler on the other side of the
center of the opening. Brace the tracks appropriately.
CONNECT TRACKS
1. Determine the length of the shaft needed to couple the two tracks
together and cut the shaft provided to that length. Slide two bearing
assemblies on the end of the shaft.
2. Install a 48B14 sprocket on each end of the shaft using the (2) 1/4" x
1-3/4" roll pin provided (Figure 1).
3. Use a tape measure to set the slider assemblies the same distance
from the wall.
4. Couple the shaft between the two idler assemblies by butting the 14
tooth sprockets together and connect with a #40 chain and master link
(Figure 2).
