8.Before the pump is placed in to operation, run the engine for several minutes. Check for fuel leaks, and noises that would associate with a lose component.

9.To begin pumping, place the throttle lever (See Figure 13) in the RUN position. If water is not flowing out of the discharge port, turn off the engine and check for and clear any obstructions within the suction hose.

WARNING

Water must always be flowing through the pump casing while the engine is running. Loss of flow may be the result of a loss of prime, restricted water flow or a dead- head situation. Please note that in such a condition, water in the pump can reach temperatures of 150-200°F in 15 to 20 minutes. This can cause serious burns if this hot water comes into contact with unprotected skin.

Before touching or opening the fill plug or drain plug, first turn off the engine and allow the pump casing to cool to the touch, and then open the pump carefully. Be cautious of any built up water pressure.

CAUTION

ALWAYS run engine at full speed while pumping.

STOPPING THE ENGINE

Normal Shutdown

1.Move the throttle lever to the IDLE position (See Figure 14) and run the engine for three minutes at low speed.
