RAIL/CHAIN ASSEMBLY

Refer to Figure 1 parts illustrations. The part names and item numbers are
referenced identically to the part names and numbers in the assembly procedures
that follow. Before starting assembly of the operator track check for the
proper length. The tracks are supplied for 8 Foot, 10/12/14 Foot,
16/18 Foot and 20/22 Foot high doors. The tracks should be
three (3) feet longer than the door height. If the tracks		107068
supplied with the operator are longer than the door
height plus 3 feet, it will be necessary to cut off two
feet (or 4 feet for 10 Foot rail) from the power head
mounting end as shown in Figure 2.
CAUTION: WHEN NECESSARY TO
CUT THE TRACK ENSURE THE
ENDS ARE LINED UP AS IN
