control levers so that the arrows point DOWNWARD. Now with the jacking
lever, lower the mast until the slot in the last mast section engages the peg in
the azimuth plate.
STEP 4:
When the antenna height is 50 FEET use this step. Refer to Fold-Out 7 while
reading this step. Continue jacking, inserting, and locking mast sections until
the sixth mast section is locked in position. Jack the sixth mast section up
until the joint between the fifth and sixth mast section is just clear of the
launcher top plate. Climb the launcher steps and fit a guy attachment ring into
the gap in the joint between the fifth and sixth mast sections. Snap the white-
coded guy wires into the holes in the guy attachment ring. One of the guy
wire snaps holds the two sections of the guy attachment ring in place. Three
sets of guy wires are used to secure the 50-foot mast. Next connect the middle
cable grip of the 50-foot cable to a free hole in the guy attachment ring.
Resume jacking, inserting, and locking mast sections until the last mast
section is locked in position. DO NOT JACK UP THE LAST MAST
SECTION. Make sure that the yellow stripe at zero degrees on the azimuth
plate is in line with the yellow stripe on the last mast section. Then set the
two brake control levers so that the arrows point DOWNWARD. Now with
the jacking lever, lower the mast until the slot in the last mast section engages
the peg in the azimuth plate.
STEP 5:
Refer to Fold-Out 7.
Tension the guy wires by feeding the wires thru the snubbers so that the mast
is straight and vertical and the guy wires are just tight. Lock the snubbers.
Compare the mast with a known vertical object or with a plumb line from the
front and one side. Check for straightness by comparison of the guy wires.
Final adjustment to the guy wires will be made later.
STEP 6:
Remove the pin from the clevis on the operating rod of the
lower brake ring and move the jacking lever to its stored position.
