TM 5-4310-386-14Prepare the blend in the tank itself: fill in the gasoline first, then add diesel fuel. The blend is as easily flammable aspure gasoline. A mixture of the latter, however, is permissible for a short period only, but never for permanent operation.CAUTIONA maximum mixture of regular-grade gasoline is 30 percent; when mixing more than 30 percent,use kerosene only. Never use premium fuel.Check hoses and ducts for cracks or other cold weather damage prior to starting compressor.Keep fuel tank full to minimize moisture condensation.a.Locate ignition switch.b.Pull the engine throttle OUT 1/4 to 1/2 (press button on top of throttle control to release from position).c.Disengage clutch.d.Turn safety bypass switch to ON.e.Press and hold relay latch button in.CAUTIONDo not actuate starter for more than 20 seconds at a time. Wait one minute between eachstarting attempt.f.While engine is cranking, pump ether injection pump (item 6, figure 2-4) very slowly. Stop pumping just asengine starts.g.Let the engine run about five minutes before engaging the clutch.NOTEEngage clutch before turning safety bypass switch to OFF.h.Once the clutch is engaged, the bypass switch must be placed in the OFF position, activating the lowpressure safety shutdown.i.The compressor will deliver air until the final pressure gauge reads 3200 psi. The unloader valve will openautomatically and dump air until the pressure drops down to 2800 psi if this amount is exceeded. This cyclewill repeat itself automatically.CAUTIONThe condensate heater should only be operated when the engine is running, since the heatingelement uses energy from the electrical system. In cold weather, 32°F (0°C), the condensateheater should be left on until the unit is shut down.2-16
