Preventive Maintenance Air System Function Test Scheduled maintenance should be performed on the Medium Duty air system, as outlined in the Medium Duty Maintenance Manual and Table 5. In addition, perform an Air System Function Test at least every 3 months or if there is any indication of a potential problem. Air Tanks The front (secondary) service tank is underneath the cab, on the driver's side; the wet (supply) tank is underneath the front service tank, behind the battery box; and the rear (primary) service tank is attached to the left frame, just behind the cab. The supply tank (or “wet” tank), must be drained on a daily basis. Drain the supply tank by pulling the drain valve lanyard. Hold it open until the escaping air is free of water. The two service tanks (or “dry” tanks), must be drained on a weekly basis. Drain the two service tanks by opening the drain valves. Turn valve handles counter-clockwise, and leave open until the escaping air is free of water. Air System WARNING! If the supply and service tanks are not drained at the recommended frequency, water could enter the air lines and valves. This could cause corrosion or blockage, which could compromise the brake system safety and potentially cause an injury accident. FRONT SECONDARY (SERVICE) TANK Location of Air Tanks DRAIN VALVE REAR PRIMARY (SERVICE) TANK WET (SUPPLY) TANK UNDER FRONT SERVICE TANK 02602 Periodically: Clean filter screens ahead of the valves by removing the screens and soaking them in solvent. Blow them dry with pressurized air before reinstalling them. Medium Duty (R05/09) Y53-6008A – 193 –
