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 15–20 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, then open the pump carefully. Be
cautious of any built-up water pressure.
CAUTION
ALWAYS run the engine at full speed while pumping.
