all hose connections are complete.

7. Open the tank suction valve.
8. Check the master discharge gauge to see if priming is necessary. Start the prim-
ing pump - pull the control handle or press the prime push button.
CAUTION!
IF DISCHARGE GAUGE READING DOES NOT INCREASE, THE INTAKE GAUGE READ-
ING DOES NOT FALL BELOW ZERO, OR THE PRIMING PUMP DOES NOT DISCHARGE
WATER TO THE GROUND WITHIN 30 TO 45 SECONDS, DO NOT CONTINUE TO RUN
THE PRIMING PUMP.
STOP THE PUMP AND CHECK FOR AIR LEAKS OR POSSIBLE PROBLEMS. SEE SEC-
TION 6 “TROUBLESHOOTING,” ON PAGE 93.
9. Gradually open the engine throttle until the desired pressure or flow is achieved.
10. As the throttle is opened, the pressure gauge reading increases with the engine
speed. If the engine speed increases without an increase in pressure, the pump
may be cavitating. Also see Section Appendix G: “Cavitation” on page 193.
11. If the pump is cavitating, warn personnel.
WARNING!
DO NOT OPEN THROTTLE UNTIL ALL GREEN PUMP LIGHTS ARE ON. (SEE FIGURE 4-
