OPERATION
PRIMING THE PUMP
Before starting the engine, remove the filler cap from the pump chamber, and
completely fill the pump chamber with water. Reinstall the filler cap and tighten
it securely.
Priming water capacity:
WT20X: 3.70 US gal (14.0 L)
WT30X, WT40X: 3.96 US gal (15.0 L)
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.
