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.
• 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 50
mph (80 km/h) could cause trailer tip-over resulting in death
or serious injury. Do not operate with the light tower raised
in winds exceeding 50 mph (80 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 50
mph (80 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).
