adjustment and repacking will be required to maintain the
C

vicing the axle, see the AL-KO axle owner's manual.
Trailer Lighting
Towing Hazard
• Towing the light tower trailer with inoperable trailer
Trailer lights are a safety feature, and are required by law.
Keep the trailer lights in proper working order.
• Check the trailer lights and wiring for damage or wear.
Repair or replace as needed.
• Check to be sure the wiring harness is secured to the
trailer and does not hang down to the ground.
• Check the trailer light housing assemblies for damage or
leaks. Use silicone or rubber sealant to seal the lens or
harness, as needed, or replace the housing assembly.
Electrical grease will help protect the sockets and pre-
vent corrosion.
• When replacing bulbs, be sure to use the correct
replacement bulb. A small amount of electrical grease in
the sockets will prevent corrosion.
For trailer wiring schematic information, refer to the separate
Wire Schematic Manual.
