2.8.4
Carefully move the device upward until the three
markers are just touching the latch barrels. At this
point, move the ring upward another foot. This causes
the markers to slide down towards the latch pins and to
become positioned relative to the latch barrels.

2.8.7
Remove the cable markers from the hoisting
cables and store with portable drive motor.
2.8.8
Rotate each latch and flag to be certain that they
rotate freely. Return them to the unlatched position,
tangent to the ring.
2.8.9
Raise the mounting ring to the top of the pole and
latch it to the headframe as instructed in Section III,
"Operating Instructions."
WARNING
Be certain the swage fitting on the end of the winch
cable does not wrap onto the winch drum before the
torque limiter disengages the drive. If the swage fitting
begins to wrap onto the drum, stop the motor and lower
the ring. Mark the three hoisting cables an appropriate
and equal amount above the latch pins to insure the
swage fitting will not wrap onto the drum. Slide the
terminal fittings up until all three latch pins meet the
new marks. It may be necessary to tap on the bottom
of the terminal fittings to free them. Use the adjustment
nuts as necessary. Failure to do this can cause
damage to the swage fitting, potentially resulting in
property damage, injury or death.
CAUTION
Carry out the following step to remove any excessive
twist that may have been introduced into the cables
during installation.
2.8.10
When the ring is initially raised and latched with
the full weight of luminaires, the clevis with hoisting
cables and power cord may rotate and twist a few turns
due to the “constructional stretch” inherent in new
cables. With the device latched and the load off the
cables, remove the twist by rotating the clevis until the
hoisting cables and the power cord appear to be
hanging straight. Use a good flashlight or other hi-
power light source to visually check as you remove the
twist.
2.8.11
Turn off the circuit breaker. Disconnect the
circuit breaker cord from the portable drive motor or
transformer and connect it to the pole power cord and
turn on the circuit breaker.
2.8.12
Remove the portable drive motor, place the
manual in the plastic pouch provided and secure it inside
the pole. Install the handhole cover.
2.8.5
Lower the ring to no less than four feet above pole
base. Make sure the ring is hanging free on the hoisting
cables. Accurately measure the distance from top of
each wooden cable marker to the top of the latch pin.
(See Figure 24)
2.8.6
Rotate the adjustment tubes until the distances
from the top of the markers to the latch pins are the
same for all three hoisting cables within +/- 1/16”. Then
tighten the locking nut to secure adjusting tube in
position. Note that there is a small (1/4") flat on the
threaded end, DO NOT unthread down past this when
doing adjustments. (See Figure 25)
