Unit Setup
Figure 3-1. Setup Components
1. For maximum light coverage, position the unit at
ground level or in a spot higher than the area being
illuminated by the lamps.
NOTE: For mast height, see Unit Dimensions.
2. Place the unit on firm ground that is relatively flat
(less than 5° slope).
NOTE: Use the bubble levels (H) to level the unit.
3. Block the wheels to prohibit movement. This will
make it easier to level the unit.
4. See Figure 3-1. Pull the locking pin (A) on the
tongue jack (E) and rotate the jack 90°. Reinstall
the locking pin. Rotate the jack handle clockwise to
raise the trailer tongue off the towing vehicle.
5. A grounding stud (B) is located on the rear frame of
the trailer near the left side outrigger. For ground-
ing requirements, follow local, state, or National
Electrical Code (NEC) guidelines.
6. See Details C–D. Pull the locking pins (C) on the
outriggers (D) and pull each outrigger out until the
spring loaded locking pin snaps back into place.
Pull the locking pin on each outrigger jack (F) and
rotate each jack 180° so the jack pad is facing
down. Reinstall the locking pin.
