Thermal Relief Valve

Bypass Mode: Allows water to re-circulate within pump when the gun trigger is not pulled.

Allowing the unit to run for more than

two minutes without the gun trigger pulled could cause overheating and damage to the pump.

Chemical Injection System: Mixes cleaners or cleaning solvents with the water to improve cleaning effectiveness.

Water Supply: All pressure washers must have a source of water. The minimum requirements for a water supply are 20 PSI and 5 gallons per minute.

Thermal Relief Valve: When the temperature inside the pump rises too high the valve will open and release a gush of water in an effort to lower the temperature inside

the pump. The valve will then close.

PRESSURE WASHER OPERATING FEATURES

PRESSURE ADJUSTMENTS

The pressure setting is preset at the factory to achieve optimum pressure and cleaning. If you need to lower the pressure, it can be accomplished by these methods.

1.Back away from the surface to be cleaned. The further away you are, the less the pressure will be on the surface to be cleaned.

2.Change to the 40º nozzle - this nozzle delivers a less powerful stream of water and a wider spray pattern.

DO NOT attempt to increase pump pressure. A higher pressure setting

than the factory set pressure may damage pump.

The nozzles for the spray wand are stored in the gatling spray wand. See chart to choose the correct nozzle for the job to be performed.
