16. Adjust the chain tension by turning the motor bumper
screw with a blade screw driver. Adjust the motor
mount bumper screw until 1/4” deflection exists when
exerting pressure on the chain. Secure the motor
mount bumper screw in place with the jam nut using a
7/16" wrench. Refer to Figure 122.
17. The motor wire connection points are as follows: the
white wire connects to terminal “G”, the red wire
connects to terminal #5 and the blue wire connects
to terminal #2. Trim the motor wires with a diagonal
cutter allowing an extra two inches of wire between
the motor and the connection points. Strip 1/4" of
wire insulation from the end of each wire. Crimp a
supplied ring tongue connector to the end of each
wire, making sure the wire is fully inserted into the
ring tongue connector. The wire should not stick out of
the connector by more than 1/16 (1.5 mm) of an inch.
Attach the ring tongues to the motor connection points
on the terminal board as described above. Refer to
Figure 123.
