Tires, Wheels and Loading The compressor is controlled by an instrument panel mounted switch below the radio. The compressor cannot be turned on unless the vehicle ignition is in the ON position Note: The air compressor uses significant electrical current when operating. It is recommended that the engine be running when the compressor is in use to avoid discharging the battery. When the compressor is switched to the on position, a light in the switch will be illuminated and the reservoir pressure will increase until it reaches the pre-set limit. The light will remain on even when the pre-set pressure limit is reached and the compressor turns off. With the switch turned on, the compressor may start at any time the ignition switch is in the ON position. You should turn the compressor switch off until you plan on using compressed air to avoid possible injuries and minimize wear on the compressor and system. Note: When the system is pressurized, all air lines from the compressor to the outlet chuck are pressurized as well. Do not attempt to work on the system or loosen any fittings unless you have drained all pressure from the system by opening the drain on the air reservoir. Whenever the air compressor has been used, be sure to drain the air system of all pressure by opening the drain valve at the front of the reservoir until air no longer escapes. Do not leave the system pressurized when the vehicle is not in use. This will help to assure the safety of those who may need to work on the truck and prevent the condensation of water in the reservoir, extending the life of air system components. The air compressor inlet is equipped with a filter to prevent the ingestion of contamination into the compressor and air system. This filter is located underneath the truck, by the forward stake pocket on the left side of the bed. If operating the air system in dusty areas, periodically inspect this filter and replace it if found to be clogged or damaged, or if the time needed to pressurize the system starts to become extended. 9
