Priming The Pump - Honda WH20 Owner's Manual

PRIMING THE PUMP

Before starting the engine, remove the filler cap from the pump chamber, and
fill the pump chamber with water up to its priming water filling level. Reinstall
the filler cap, and tighten it securely.
Operating the pump dry will destroy the pump seal. If the pump has been operated
dry, stop the engine immediately, and allow the pump to cool before priming.
If the discharge hose must run across a roadway, the hose should cross the
roadway perpendicular to traffic flow. Also, heavy boards should be placed next
to the hose so the motor vehicle weight does not shut off the discharge as
vehicles cross over the hose.
Driving over a discharge hose while the pump is running, or even possibly when
the pump is stopped, may cause pump case failure.
