PURGING AIR FROM THE PUMP

Running a pressure washer pump without water will severely damage the pump seals
and other internal components. To avoid this hazard, make sure your water supply is
uninterrupted and at least 5 GPM at 20 PSI, and always purge the air your pressure
washer pump before starting the engine.
The high pressures created by a pressure washer can cause fluid injection injuries,
severe lacerations, amputations, and / or death. To avoid these hazards, always aim
the spray gun and lance in a safe direction when using the pressure washer and never
attempt to touch a leak in a high-pressure hose or fitting.
A pressure washer pump is designed to operate with water flowing through it. Water
