Disassembly/Assembly Procedures
Disassembly:
Turn the lights off, turn the unit off, and lower the mast assembly into
the cradle before performing this 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 lower 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.
When replacing the upper mast cross member (j) only, disconnect the
wiring cable clamps (m) and the junction box (l), then simply replace
the cross member. When replacing cables or portions of the mast, the
junction box may remain mounted to the cross member. Disconnect
the wiring cable clamp (n) from the mid mast, then disconnect the
cross member with the box attached and place it near the trailer.
