Using the Wylie Express Combo Trailer is easy. First, make sure it's properly connected and parked on a stable surface. For the water system, you can use the 5 - GPM, 45 - PSI water pump to draw water from the 500 - gallon tank as needed. The generator can be started following the standard procedure in the owner's manual. It can run for up to 300 hours with the 240 - gallon fuel tank. The light tower can be hydraulically raised to provide illumination. When it comes to maintenance, regularly check the water and fuel levels. Inspect the trailer's surge brakes and the 7' channel iron construction for any signs of wear. In cold weather, if you have the optional freeze - protection module, make sure it's working. If not, take steps to protect the water components from freezing. Always refer to the owner's manual for more specific maintenance instructions.
