PRESSURE WASHER TERMINOLOGY

PSI: Pounds per Square Inch. The unit of measure for water pressure. Also used for air pressure, hydraulic pressure, etc. PSI*: Pounds per Square Inch. The unit of measure for water pressure. Also used for air pressure, hydraulic pressure, etc. GPM*: Gallons per Minute. The unit of measure for the flow rate of water.

• Rated Pressure and Rated Water Flow is within manufacturing tolerance of (+/- 10%). Bypass Mode: Allows water to re-circulate within the pump when the gun trigger is not pulled. This feature allows the operator to release the trigger gun and reposition themselves without having to turn the engine off in between cleaningactions.

WARNING: Do not allow the unit to run for more than two minutes without

the gun trigger being pulled. This could cause overheating and damage to the pump. When the temperature inside the pump rises too high, the thermal relief valve will open and release a spray of water from the pump to lower the internal temperature. The valve will thenclose. Thermal Relief Valve (P, Fig. 5): When the temperature inside the

pump rises too high, this valve will open and release a gush of water in an effort to lower the temperature inside the pump. The valve will thenclose. NOTE: Thermal relief valve location will vary depending on the pump type. Detergent 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. If your water source is a well, the garden hose length can only be 30ft. (9m) max.

WARNING: To reduce the possibility of contamination always protect

against backflow when connected to a potable watersystem.

PRESSURE WASHER OPERATING FEATURES

PRESSURE ADJUSTMENTS The pressure setting is preset at the factory to achieve op ti mum pres sure and cleaning. If you need to lower the pres sure, it can be accomplished by these meth- ods.

1. Back away from the sur face to be cleaned. The further away you are, the

less the pressure will be on the surface to becleaned.

2. Change to the 40˚ nozzle (white). This nozzle delivers a less powerful stream

of water and a wider spray pattern. Refer to How To Use SprayWand. NOTICE: DO NOT attempt to increase pump pressure. A higher pressure setting than the factory set pressure may damagepump. HOW TO USE SPRAY WAND (IF EQUIPPED WITH QC NOZZLES) The nozzles for the spray wand are stored in the nozzle holder on the panel assembly.
