Safety Warnings

          

CAUTION

Never set up the tower within 120 feet of a power line.

Never erect the tower during an electrical storm, rainstorm, or when lightning is a possibility.

Never climb the tower for any reason. Always lower the tower completely and access it with a 
suitable ladder or platform.

Never overextend the tower height. When at maximum height, the orange rung on the second 
tower section (from the bottom) rests on the orange safety stop (at the top of the base tower 
section).

Always tow the trailer in a level position to meet height restrictions. Adjust coupler height as 
needed.
