Work Site Considerations
Prior to setting up the Eclipse 2400 Series arrow board trailer,
the operator must determine where to place it on the work
site. Consideration must be given to ground conditions, over-
head clearance, wind, and sign board visibility.
It is the operator's responsibility to ensure that the arrow
board 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.

Ground Conditions

WARNING
Rollover Hazard
• Positioning the arrow board trailer on soft or unstable
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 sign board.
The arrow board trailer must be placed on a firm, stable
surface that will support the total weight of the trailer, and
support the force exerted on the ground by each of the four
outriggers as well as the tongue jack. Make sure the surface
has enough area to allow full extension of all outriggers and
the tongue jack. The surface should be level, and must not
exceed a grade of 5% (2.8° incline) in any direction. Grades
greater than 5% may exceed the extension limits of the out-
riggers and prevent the trailer from being properly leveled.
Overhead Clearance
DANGER
Electricution Hazard
• Contact with overhead electrical wires will result in
death or serious injury. Always follow the rules or
instructions for your work site, and the state, province
and federal rules for maintaining a safe distance from
overhead wires.
Make sure there are no overhead obstructions in the area
where the arrow board trailer is to be placed, keeping in mind
the total height of the arrow board trailer with the sign board
in the operating (vertical) position. See "Specifications".
Always keep well clear of overhead electrical wires. Also
keep clear of loose cables, ropes or obstructions that could
ensnare the sign board.
When in the operating position, the solar panel should be
exposed to sunlight for the majority of daylight hours. The
solar panel requires adequate sunlight to maintain battery
charge, and should not be in shady areas.
Wind
WARNING
Unsafe Operation Hazard
• Operating the arrow board trailer with the sign board
in the operating position in winds exceeding 50 mph
(80 km/h) can cause trailer tip over resulting in death
or serious injury. Always lower the sign board when
winds are expected to exceed 50 mph (80 km/h).
When positioned on level, stable ground with the outriggers
deployed and the sign board raised in the operating (verti-
cal) position, the arrow board trailer is designed to withstand
sustained winds of 50 MPH (80 km/h) without tip over. This
does not include the addition of wind generated by passing
vehicles.
When placing the trailer on the work site, be aware of ground
obstructions such as structures or trees that may direct wind
toward or cause buffeting around the arrow board trailer.
As noted, wind generated by passing vehicles will also affect
the arrow board trailer. Position the trailer with sufficient dis-
tance from traffic lanes to minimize the effect of wind gener-
ated by passing vehicles.
Visibility
The arrow board should be visible to oncoming traffic at
least 1 mile (1.6 km) away. Be aware of ground obstruc-
tions that may block visibility, such as structures or trees.
Consideration should also be given to intersections, on and
off ramps, and other diverting lanes or roadways. Also be
aware of the curvature of the roadway approaching the arrow
board.
Always confirm the visibility of the arrow board by observing it
from various vantage points on the roadway approaching the
arrow board.
Use the eyelets to assist in positioning the arrow board. See
"Using the Eyelets to Position the Trailer".
Using The Eyelets To Position The
Trailer
The eyelets located midway up the left side frame uprights
(as viewed from the rear of the arrow board) are used to sight
through to assist in positioning the arrow board at the work
site.
1. Position yourself at the front (tongue end) of the arrow
board trailer, facing oncoming traffic.
2. Locate a point on the roadway (A, Figure 8) approximate-
ly 1 mile (1.6 km) (B) from the arrow board in approach-
ing traffic.
3. Sight through both eyelets (C, Figure 8) and determine
where the point in approaching traffic is relative to the
eyelets.
