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

full speed
