TM 9-4310-397-14 SECTION I DESCRIPTION AND USE OF OPERATOR'S CONTROLS AND INDICATORS 2-1. CONTROLS. This section describes and illustrates the controls and indicators to ensure proper operation of the compressor. The information that follows references the control components found in Figure 2-1. a. Diesel Aid Starting. The DIESEL AID STARTING Switch (1) is used in cool weather below 40° F (5°C). Ethyl ether will be injected into the engine and aids in the startup procedure. b. Relay Reset Switch. Manual reset switch (2) that opens and shuts off fuel from the engine when either of the switches (compressor oil temperature, engine water temperature or tachometer) are tripped. Must be reset by pushing after conditions have dropped below trip point. CAUTION Operating the PRIMING PUMP when either ambient temperatures are below 100°F (38°C) or more than one time during a starting cycle will inject excessive fuel into the engine and can cause equipment damage. c. Priming Pump. The PRIMING PUMP (3) is for hot starting whether it is from repeated engine starting or hot weather (100°F or above) (38°C). The hot day starting aid requires only one pumping stroke. Additional pumping strokes could cause engine damage. d. Ignition Switch. The IGNITION SWITCH (4) uses three positions to make or break the electrical circuit. The switch is pulled outward through the run position for starting and when engine starts the spring loaded switch is released to return to the run position. Pushing the switch inward from the run position opens the circuit stopping the unit. The safety override switch must be pressed simultaneously with this switch in the start position. CAUTION Operating the engine with low or no oil pressure can cause serious equipment damage. e. Safety Override Switch. The SAFETY OVERRIDE SWITCH (5) is pressed simultaneously with the start switch during starting only. It is used to override the engine low oil pressure safety switch. The switch must be held until oil pressure is greater than 10 psi (0.7 kg/cm²); and then released. f. Lamp Switch And Lamps. The LAMPs (6) illuminate the panel and are turned on or off using the toggle LAMP SWITCH (7) marked ON and OFF. g. Compressor Unloader And Idle Control. The COMPRESSOR UNLOADER AND IDLE CONTROL (8) is used to manually close the compressor air intake by turning the knob fully clockwise. When the knob is turned fully counterclockwise the compressor intake is automatically controlled by system pressure. h. Hose Reel Valve. The hose reel valve (9) is opened or closed to control air flow through the hose. i. Double Discharge Valve. The double discharge valve (10) is used to control air flow through any additional equipment connected to the unit. 2-2
