Operating Instructions and Parts Manual

Glossary

Become familiar with these terms before operating the unit.

Cavitation - The shock of thousands of bubbles collapsing inside the pump quickly, pitting metal surfaces and seals. Cavitation is caused by lack of water at the inlet of the pump.

Detergent Injection System - Cleaning detergents are drawn into the water stream making cleaning more effective by allowing detergents to saturate the soiled surface. An injector allows the soap to be injected into the water stream, making cleaning faster and easier than water alone.

GPM (Gallons per Minute) - More water per minute can mean faster cleaning, especially when washing off materials like mud and road tar.

GFCI (Ground Fault Current Interrupter) - GFCI protects user from accidental electrocution (for electric powered pressure washers only).

High Pressure Outlet - A connection for high pressure hose.

HP (horsepower) - A unit of measure for work.

Nozzle (quick Connect Spray Tips) - The nozzle is the restriction at the end of the wand that creates the pressure. Nozzles have different spray patterns that can affect the width and strength of the spray. The 40-degree (white) nozzle delivers a flat spray of about 40-degrees. There’s also a 25-degree (green) and the most popular 15-degree (yellow) nozzles. The 0-degree (red) nozzle should be used with caution, it can cut into wood and cause damage.

PSI (Pounds per Square Inch) - A unit of measure for pressure. It determines how much pressure is directly applied on the surface being cleaned. The pressure that is delivered by the pressure washer is directly responsible for breaking the bond between the debris and the surface being cleaned.

Thermal Relief - A technique used to reduce the build-up of high temperature water within a pressure washer pump caused when the spray gun trigger is closed. This system prevents internal pump damage by cycling water through pump when water reaches maximum water temperature. Warm water will discharge from pump onto ground.

Unloader - A device used to relieve the water pressure within the pump whenever the spray flow is blocked. It allows the motor to continue running when the operator releases the trigger on the spray gun and stops washing. It diverts the pressure, that would build up without the unloader, by taking the water from the exit side of the pump and loops it back to the inlet side in a continuous “bypass” mode. The unloader will return the flow of water to the spray gun when the operator presses the trigger.
