STARTING THE PUMP UNIT - Continued
g. Turn the IGNITION switch (5) to the START position. Release switch when the engine starts. Do not allow the
engine to crank for more than 10 seconds without letting the starter cool down. Check to see that the LOW OIL PRESSURE
LIGHT (6) goes out when the engine starts. If not, shut down immediately.
h. If the temperature is below 40F (4.44C), operate the ENGINE PRE-HEAT SWITCH (9) for an additional minute
or until the engine begins running smoothly.
i. At first, the water PRESSURE GAGE (10) may indicate zero and the VACUUM GAGE (11) may indicate from 0 to
15 inches of mercury depending on the height of the pump above the level of water. When the pump is fully primed, the
sound of the pump will change noticeably and the water PRESSURE GAGE should indicate between 60 and 120 psi.
(90 psi is a normal reading.) If pressure gage does not show pressure, stop engine and check hose connections and valve
settings.
CAUTION
Close VALVE NO. 4 PRIME before the prime-detergent tank is empty. If the valve is not closed, all
vacuum or pressure is lost due to air being drawn into the pump from the prime-detergent tank.
8. Close VALVE NO. 4 PRIME (2) immediately when the pump is fully primed.
