your vehicle to make turns. Make sure these chains attach securely to your vehicle and do not drag on
the roadway.

needs slack to allow your vehicle to make turns. Do NOT allow these wires to drag on the roadway.

TOWING
1. Do not exceed 55 mph on highways. Do not exceed any posted speed limits.
2. Slow Down for curves, adverse weather, hazardous road conditions, constructions zones, emergency
vehicles and expressway exits.
3. Larson Electronics doesnot recommend using cruise control or overdrive when towing.
4. Allow at least 4 seconds between you and the vehicle in front ofyou.
5. Persistent side to side motion is notnormal.If this occurs at a certain speed, itisa signal that whipping
will likely occur ifspeed isincreased. If you notice this behavior, immediately slow down and maintain
at least 10 mph below the speed when the sway was first noticed.
TRAILER PREPARATION
Prepare the trailer for mast deployment.
1. Position the trailer in a location as close to level as possible.
2. Extend all four (4) outriggers located at eachcorner ofthe
trailer. This isdone by loosening the “T” Handles (shown in picture)
on top of each outrigger and pulling them out. Rotate each jack
perpendicular with the ground and lock in place.
3. Using the jacks on the outriggers, level the trailer before using. Adjust each jack to achieve proper
leveling. Turning the handles clockwise raises the jacks and counterclockwise lowers the jacks.
4. Once trailer is leveled and stable, the mast may now be raised. Rotate the winch handle to raise
mast to desired height, and rotate in the opposite direction to lower it back down. NOTE: The T-
Head mast supports up to 120 lbs. DO NOT overload.
5. Before towing, be sure outriggers are retracted and jacks are turned horizontal for transportation.
Reconnect trailer light cable, and use tow chains.
