18 AL4000 Light Tower Part No. 833002 Rev A
5. Install the floodlights on the crossarm:
A. Remove the light fixtures from the tower by rotating the wingnuts to free the lights.
Install them on the cross arm studs with the lens facing the ground.
B. The cord on the fixture should be on the side closest to the trailer so the cord entry is
beneath the fixture when the tower is raised ( this reduces moisture problems and
insures the water weep hole in the fixture is down).
C. Set the vertical aim for each light fixture by adjusting the light fixtures and tightening the
T-handle located on the fixture.
D. Set the spread between the light fixtures horizontal aiming by adjusting the fixtures and
tightening the wing nut.
E. The unit may be transported with the light fixtures mounted on the crossarm if they
are pointed toward the ground.
6. Raising the tower (refer to drawing above):
A. Remove the tower travel-locking pin from the cradle at the rear of the cabinet.
B. Aim the fixtures, both horizontally and vertically, to the estimated angles that will light
the work area.
C. Using the winch, raise the tower to the vertical position. The tower-locking pin at the
base of the pivot post will lock automatically and you will hear it “snap” into place.
Insert manual pin into locking device.
D. Release the tension on the cable by backing the winch off slightly and pull the tele-
scoping locking pin on the galvanized tower section. Hold this out while turning the
winch to raise the tower. After the tower has telescoped slightly, the locking pin can be
released. Raise the tower to the desired height.
