Priming The Pump - Husqvarna W 100D Operator's Manual

OPERATION
PRIMING THE PUMP
Before starting the engine, remove the filler cap from the pump
chamber. Fill the pump chamber to the undersurface of the discharge
port with water. Reinstall the filler cap and tighten it securely.
NOTICE
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.
PRIMING WATER FILLER CAP DISCHARGE PORT
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.
BOARDS
DISCHARGE HOSE
Driving over a discharge hose while the pump is running, or even
possibly when the pump is stopped, may cause pump case failure.
