Disassembly:
Turn the lights off, turn the unit off, and lower the mast assembly into
the cradle before this performing procedure. Place the Light Tower in
a position with enough room so that the masts may be extended fully
while in the down position.
The mast cable system consists of two cables: one (c) connected to
the winch mounted on the main mast that raises the mid mast; and a
second (f) that is connected to both the upper mast and the main mast.
This second cable raises the upper mast as the mid mast is being
raised.
Disconnect the wiring at each light fixture's quick-disconnect or at the
junction box. Then, remove each light fixture. Store the light fixtures in
a safe place.
Using the tongue-mounted winch, raise the tower just so that the masts
are free from the cradle locking pin.
Remove the upper-mast cross member (j) with the junction box
attached.
Remove the upper-mast cable eyebolt (p).
Using the mast-mounted winch, back off the tension of the cable until
the cable may be unwound from the mast-mounted winch. Unwind and
remove the cable from the mast-mounted winch.

guides to the main mast. On machines using screws, remove the
screws to remove the five guides.
