CAUTION
Operating the PRIMING PUMP when either ambient temperature is 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.
(f)
Pull PRIMING PUMP plunger (10) completely out until it stops; then, push in slowly, spraying atomized fuel
into engine air intake.
(g)
Lock PRIMING PUMP plunger (10) in rest position by rotating knob 90 degrees after detent pin engages.
WARNING
Operating the unit in a building or any enclosed area without the exhaust gases piped outside
can result in serious illness or death.
CAUTION
Operating the engine with low or no oil pressure can cause serious equipment damage.
(h)
Depress SAFETY BYPASS switch (7) and hold. Pull IGNITION-START switch (4) and release when
engine starts. When pressure is indicated on ENGINE OIL PRESSURE gauge (8) release SAFETY
BYPASS switch (7).
(i)
If engine oil pressure does not register within three seconds after engine starts, release SAFETY BYPASS
switch (7), push IGNITION-START switch (4) in and notify supervisor.
(j)
In hot weather it may be necessary to repeat the starting procedures. If engine does not start after four
attempts, push IGNITION-START switch (4) in and notify supervisor.
(k)
When engine water temperature reaches 140° F (60° C), as indicated on ENGINE WATER TEMPerature
gauge (9), close the hose reel valve (1) and appropriate double discharge valve (2) and turn COMPRessor
UNLOADER AND IDLE CONTROL knob (3) counterclockwise until it stops. This action increases engine
speed and opens compressor intake valve to start compression.
CAUTION
Operating the equipment unattended for prolonged periods of time can result in serious
damage to the unit.
(l)
Unit is now ready for use and will cycle through load and unload automatically in relation to air demand.
As demand increases, the engine will accelerate and the compressor will replenish compressed air supply
in the separator tank. As demand decreases, or stops, engine will return to idle and compressor will run in
an unloaded condition until demand for air again causes unit to load.
(m)
Perform all the DURING PMCS as outlined in Table 2-1.
(2) Shutdown Procedure. (See Figure 2-5.)
(a) Turn COMPR UNLOADER AND IDLE CONTROL knob (3)
clockwise until it stops.
(b)
