threaded end, DO NOT unthread down past this when
doing adjustments. (See Figure 26)
2.8.7
Remove the cable markers from the hoisting
cables and store with the 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."
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 main power cord in the
pole.
2.8.12
Remove the portable drive motor, place the
manual in the plastic pouch provided and secure it inside
the pole. Hook the safety cable to the clevis, turn on the
circuit breaker and install the handhole cover.
is now ready to be raised to the top of the pole.
2.8.3
Following the operating instructions of Section III,
raise the ring and luminaires to the top of the pole,
stopping just before the wooden cable markers contact
the latch barrels.
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.
2.8.5
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.
(See Figure 25)
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 /- 1/16”. Then
tighten the locking nut to secure adjusting tube in
position. Note that there is a small (1/4") flat on the
