IV. INSTALL THE FLOODLIGHTS ON THE CROSSBEAM
A. Remove the light fixtures from the tower by removing detent pin and rotating the clamp 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 ensures 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 lower bolt.
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 cross-arm if they are pointed toward
the ground.
V. 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 fixture, 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 telescoping 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.
CAUTION : DO NOT ATTEMPT TO LEAN THE TOWER DOWN BELOW 45° WHEN IT IS
EXTENDED-SERIOUS DAMAGE MAY OCCUR!
