Operation
Work Site Safety Considerations
It is the operator's responsibility to make sure that the
light tower trailer is properly and safely positioned at the
work site. Follow state, province and federal rules, as well
as rules or instructions for the work site.
Overhead Clearance
DANGER
Electrocution Hazard
•
Raising the light tower in the presence of electrical
power lines will result in death or serious injury.
Always check overhead wires and obstructions before
raising or lowering the light tower.
•
Always follow the rules or regulations for your
worksite, and state, province and national electric
code for maintaining a safe distance from overhead
wires.
The work site must be clear of overhead obstructions
such as power lines, trees, etc. Keep in mind the
maximum height of the light tower when fully raised. See
Specifications.
Ground Surface
WARNING
Rollover Hazard
Positioning the light tower trailer on soft, unstable or
unlevel ground could cause trailer rollover, resulting in
death or serious injury. Always position the trailer on a
firm, level and stable surface and deploy the outriggers
before raising the light tower.
A
•
Do not set up the light tower trailer on an incline of
more than 2.8° (5% grade) front-to-back and side-to-
side.
•
Do not set up the light tower trailer on unlevel or
unstable ground. Set up on smooth, flat and solid
ground surfaces only.
Wind
WARNING
Rollover Hazard
Operating with the light tower raised in winds exceeding
55 mph (88 km/h) could cause trailer tip-over resulting in
death or serious injury. Do not operate with the light tower
raised in winds exceeding 55 mph (88 km/h).
When the light tower is in the operating position it is
located in the middle of a three-point outrigger system
for optimum balance and stability. This system was
engineered to allow the light tower to remain operational
in sustained winds of 55 mph (88 km/h) with the light
tower extended to full height and the outriggers in position
on a firm, level surface.
Leveling and Stabilizing the Light
Tower Trailer
WARNING
Rollover Hazard
Setting up the light tower trailer on soft, unstable or
unlevel ground could cause trailer rollover, resulting in
death or serious injury. Always set the trailer on a firm,
level and stable surface and deploy the outriggers before
raising the light tower.
1. Set the light tower trailer on a solid, level work site.
See Work Site Safety Considerations.
2. Put wheels chocks against the front and rear of each
wheel (A, Figure 11).
