PRESSURE WASHER
TERMINOLOGY
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.
CU: Cleaning Units. GPM multiplied by PSI.
Bypass Mode: In Bypass Mode, the pump is recirculating water because the trigger of the spray gun is not pulled. If unit is left in bypass mode for more than two (2) minutes, the water temperature will rise to a dangerous level and could damage internal components of the pump. Any damage to pump due to these causes will not be covered under warranty.
DO NOT allow your unit to operate in
bypass mode for more than two minutes at any time. Overheating of pump can cause damage to pump.
Thermal Relief Valve: In an effort to prevent extreme damage, pumps are equipped with a thermal relief valve. This valve will open when the temperature inside the pump rises too high. This valve will then release a gush of water in an effort to lower the temperature inside the pump. Immediately after this occurs, the valve will close. The thermal relief valve is part of the pump and is not visible to the user.
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.
HOW TO USE
IMPORTANT: Read and understand how to use the pressure washer before operating.
TO ADJUST PRESSURE
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.Rotate the nozzle at the end of the
DO NOT attempt to increase pump
pressure. A higher pressure setting than the factory set pressure may damage pump.
HOW TO USE SPRAY WAND:
Your pressure washer is equipped with a
When using the high pressure setting, DO NOT allow the
in contact with unprotected skin, eyes, or with any pets or animals. Serious injury can occur.
Risk of injection or injury to person. DO
NOT direct discharge stream toward persons.
For high pressure operation, pull back the nozzle of the
