2.2.7
Locate the free end of the second cable. Without
wrapping or crossing the cables, especially with the
cable already installed, thread this cable through its
respective opening in the cable divider plate, over the
pulleys and through the latch barrel. Continue to pull
the cable to remove the slack. String the last hoisting
cable in the same manner. Check to see that the
positions of the cable attachments to the clevis are
aligned with the openings in the cable divider plate.
CAUTION
Be sure the cables are not crossed or wrapped around
each other. Fouled cables may cause cable damage
and improper device operation.
2.2.8
Thread the power cord through the power cord
slot, near the outside edge of head frame plate, over
the power cord rollers and through the slot of the cable
divider plate adjacent to the cord roller. (See Figure 4)
2.2.9
Feed the power cord through the large center
hole in the clevis approximately 2 feet, making certain it
is centered in the three hoisting cables.
CAUTION
The power cord and cables must not be crossed or
wrapped around each other.
2.2.10
Securely fasten the compression clamp on the
power cord just under the clevis plate. The location of
the clamp is not critical at this time. The clamp will be
repositioned after the pole is erected.
NOTE
Double-check for crossed or wrapped cables and cord
at this time. With the clevis located near the slipfitter it
is very simple to check for proper assembly. After the
pole is erected, it will be nearly impossible.
2.2.11
Attach the light rope, wire or cable, which was
strung through the pole, to the U-shaped bail of the
clevis and pull the clevis into the top of the pole. (See
Figure 5)

SECTION II
2.2.12
Pick up the headframe assembly and slide the
slipfitter over the top of the pole while pulling the clevis
down the pole to take up slack in the cables. (See
Figure 6) After orienting the headframe with the power
cord on the top, aligned with the pole handhole tighten
the six set screws to 25 to 30 inch pounds .
2.2.13
Pull all cables down through the pole and stop
when the clevis is at the top of the handhole.
2.3 Installing the Winch

Unpack the winch assembly with the winch,
motor, circuit breaker and cover attached. (See Figure
