Never run the engine without the air cleaner. Rapid engine wear will

CAUTION:
Never attempt to operate the pump without priming water, or the
pump will overheat. Extended dry operation will destroy the pump
seal. If the unit has been operated dry, stop the engine immediately
and allow the pump to cool before adding priming water.
