Part No. 833002 Rev A AL4000 Light Tower 17
READ ALL DIRECTIONS IN MANUAL CAREFULLY
BEFORE OPERATING EQUIPMENT
DO NOT RAISE TOWER IN THE VICINITY OF
OVERHEAD POWER LINES!
1. Move Light Tower to desired location keeping the following in mind:
A. The light tower should not be placed where those working under the light are either:
1. Forced to look into the light regularly.
2. Forced to work with their backs to the light (shadows will block the light from the
work area).
B. The area where the tower is positioned should be relatively level.
C. The light tower should be located on the same level or on ground higher than the area
being lighted (higher light mounting heights reduce the shadow length).
D. Unit should be level to insure smooth trouble-free tower telescoping. Tower may not
telescope down properly when unit is not level.
2. Unhitch from the towing vehicle as follows:
A. Engage the trailer braking system, especially if trailer is not on level ground.
CAUTION: If electrical or manual braking system is not supplied, chock the wheels
instead.
B. Swing the tongue jack into position and raise the tongue off the towing vehicle.
3. Level the trailer, using the jacks as follows:
A. Extend the rear outriggers until the springs lock into place. Swing the jack on each
outrigger into vertical position.
B. Start at the highest jack position. Rotate the jack handle until the jack foot touches the
ground.
C. Raise the other jacks to level trailer
ensure that the rear jacks are
down to prevent the tower from tipping over backwards when raised.
4. Drive grounding rod into earth.
