damage. Replace or repair if necessary.
c Verify the rear and side levelling jacks are in the
up position, the outriggers are contracted, and all
are secured with their locking pins.

the trailer and set the tow hitch on the tow vehicle.
Ensure the tow hitch is properly engaged and
locked.

During towing
• Do not tow the trailer with any people, parts,
supplies, or additional equipment attached to it or
loaded onto it.
• Do not tow additional trailers or other equipment
in tandem with the light tower trailer.
• The recommended maximum speed for highway
towing is 45 MPH (72 km/h). For offroad towing,
the recommended maxiMum speed is 10 MPH (16
km/h) or less, depending on terrain.
• Adhere to all applicable DOT regulations when
towing the trailer.
After towing
Release the trailer tow hitch from the tow vehicle as
follows:
1. Locate the levelling jack on the trailer drawbar at
the front of the trailer.
2. Pull the locking pin and rotate the jack downward.
When the jack is properly set, the locking pin
snaps into position with an audible “click.”
3. Block or chock the trailer wheels.
4. Release the tow hitch from the ball coupler or
pintle on the tow vehicle.
5. Crank the jack handle until the jack foot touches
the ground and the tow hitch rises up off the tow
vehicle.
6. Move the tow vehicle away from the trailer.
Hoisting
The light tower may be hoisted by means of the hoist
ring mounted on the mast (see Figure 3.2).
Prior to hoisting:
• Ensure the mast is in the horizontal (travel)
position, fully nested in the transport cradle, and
secured in place with the horizontal-lock pin (see
Figure 3.2).
• Close and latch the side doors and maintenance
(top) panel.
• Return levelling jacks and outriggers to the travel
position, and ensure they are all secured in place
with their locking pins.
