WARNING
Towing Hazard
• Towing a trailer with damaged tires, rims or lug nuts
could result in death or serious injury. Never tow the
trailer with damaged tires, rims or lug nuts.
1. Check the tires for any cracks, cuts or damage. Repair or
replace the damaged tires before towing.
2. Check the air pressure of the trailer tires when cold.
See Specifications.
3. Check the wheel rims for any cracks or damage.
4. Check the brakes to make sure that they work properly.
5. Make sure all the lug nuts are in place. Never tow the
trailer with missing or improperly tightened lug nuts.
6. Check that the lug nuts are tightened properly. The
correct torque for the lug nuts is 90 lb-ft (122 Nm).
7. When torquing lug nuts, always use a criss-cross pattern
(Figure 32).

Wheel Bearings
Refer to the axle manual for information regarding
maintenance of wheel bearings and other axle components.
Trailer Lighting
WARNING
Towing Hazard
• Never tow the trailer with inoperable trailer lights. Lights
are a vital safety feature of your trailer and are also
required by state law. Keep the lights in proper working
order.
1. Check the trailer lights and harness for damage or wear.
Repair or replace as needed.
2. Make sure the harness is secured to the trailer and does
not hang down onto the ground.
3. Check the taillight housing assemblies for damage or
leaks. Use silicone or rubber sealant to seal the lens or
harness, as required, or replace the housing assembly.
Electrical grease will help protect the sockets and prevent
corrosion.
4. When replacing bulbs, make sure the proper bulb is
used and use a small amount of electrical grease in the
sockets to prevent corrosion.
5. For trailer wiring schematic information, refer to the
separate Wire Schematic Manual.
Cleaning
WARNING
Entanglement Hazard
Failure to shut down the engine before cleaning the unit
could result in death or serious injury. Always shut down the
engine before cleaning the unit.
WARNING
Burn Hazard
Shut down the engine and lights and allow ample time for
components to cool before cleaning the unit. Failure to do
so could result in serious burns.
NOTICE
Use caution when using compressed air or water / steam
pressure washers. Do not pressure–clean electrical
components, as this may cause damage.
Keeping the light tower clean is important to ensure proper
operation. Dirt and dust buildup acts as an insulator and may
cause the engine, generator and light assemblies to operate
at excessively high temperatures.
Use the following as cleaning guidelines:
1. Clean the light tower trailer to remove all dust, dirt or
other foreign material.
2. Clean the light tower and light fixture assemblies with a
damp cloth or sponge.
3. Clean all electrical wiring and components by hand using
non-corrosive cleaner.
4. Clean the inside of the engine compartment.
5. Clean any oil or liquid spills inside the engine
compartment.
6. Empty the fluid containment tray. See Draining the Fluid
Containment Tray.
Draining the Fluid Containment Tray
The unit contains a fluid containment tray designed to catch
fuel, oil or coolant spills. To drain:
1. Position a suitable container beneath the fluid
containment drain, located beneath the unit.
2. Remove the drain plug.
3. Allow the fluid to drain completely into the container.
4. Reinstall the drain plug.
