Prepare the blend in the tank itself: fill in the gasoline first, then add diesel fuel. The blend is as easily flammable as
pure gasoline. A mixture of the latter, however, is permissible for a short period only, but never for permanent operation.
CAUTION
A 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.
CAUTION
Do not actuate starter for more than 20 seconds at a time. Wait one minute between each
starting attempt.
f.
While engine is cranking, pump ether injection pump (item 6, figure 2-4) very slowly. Stop pumping just as
engine starts.
g.
Let the engine run about five minutes before engaging the clutch.
NOTE
Engage 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 low
pressure safety shutdown.
i.
The compressor will deliver air until the final pressure gauge reads 3200 psi. The unloader valve will open
automatically and dump air until the pressure drops down to 2800 psi if this amount is exceeded. This cycle
will repeat itself automatically.
CAUTION
The condensate heater should only be operated when the engine is running, since the heating
element uses energy from the electrical system. In cold weather, 32°F (0°C), the condensate
heater should be left on until the unit is shut down.
