OPERATING INSTRUCTIONS

BASIC ELEMENTS OF A PRESSURE WASHER

High Pressure Pump: Increases the pressure of the water supply. Engine: Drives the high pressure pump. High Pressure Hose: Carries the pressurized water from the pump to the gun

and spray wand. Spray Gun: Connects with spray wand to control water flow rate, direction, and

pressure. Quick Connect Spray Wand: Spray wand is equipped with a female quick

connect coupler on the end. This allows the user to quickly change out high-pressure nozzles for different spray patterns and change to the soap nozzle for low pressure and chemical/soap applications. See How To Use Spray wand paragraph in this section.

Chemical Hose (not shown): Feeds cleaning agents into the pump to mix with the pressurized water. See How To Apply Chemicals/Cleaning Solvents in Operation section of this manual.

BASIC ELEMENTS OF ENGINE

Refer to the engine manual for location and operation of engine controls.

Choke Control: Opens and closes carburetor choke valve Throttle Control Lever: Controls engine speed. Starter Grip: Pulling starter grip operates recoil starter to crank engine. Fuel Valve Lever: Opens/closes connection between fuel tank and carburetor. Engine Switch: Enables and disables ignition system.

READ THIS OPERATION MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with the location of various controls and adjustments. Save this manual for future reference.

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.

Chemical Injection System: Mixes cleaners or cleaning solvents with the pressurized 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.

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 - white, 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.

3. Adjust the pressure regulator on the pump. Tur n

the pressure regulator knob counterclockwise to lower pressure. Refer to the illustrations to identify your pressure regulator. Once you have finished using your pressure washer, return the pressure regulator to its original position by turning it clockwise.

DO NOT try to turn pressure regulator knob past the built-in stop or damage to pump will result.

TO USE SPRAY WAND

Your pressure washer is equipped with five spray nozzles. Each nozzle is color coded and delivers a specific spray pattern for a particular cleaning purpose. The size of the nozzle determines the size of the fan spray and the pressure out of the nozzle. The 0º, 15º, 25º, and 40º nozzles are high pressure nozzles. The chemical nozzle is a low pressure nozzle.

The nozzles are housed in receptacles on the panel of the pressure washer handle. Colors on the panel identify nozzle location and spray pattern.

Risk of injection or injury to person. Do not direct discharge stream toward persons, unprotected skin, eyes, or any pets

or animals. Serious injury can occur. Changing Nozzles

DO NOT attempt to change nozzles while pressure washer is running.

Turn engine off before changing nozzles.

1. Pull quick connect coupler back and insert nozzle.

2. Release quick connect coupler and twist nozzle to make sure it is secure in coupler.

Risk Of Injury. Ensure nozzle is

completely inserted in QC socket, and QC snap ring is fully engaged (forward) before squeezing gun trigger.

0º nozzle - Red. This nozzle delivers a pinpoint

stream and is extremely powerful. It covers a very small area of cleaning. This nozzle should only be used on surfaces that can withstand this high pressure such as metal or concrete. Do not use on wood.

15º nozzle - Yellow. This nozzle delivers a powerful 15 degree spray pattern for intense cleaning of small areas. This nozzle should only be used on areas that can withstand the high pressure from this nozzle.

25º nozzle - Green. This nozzle delivers a 25 degree spray pattern for intense cleaning of larger areas. This nozzle should only be used on areas that can withstand the pressure from this nozzle.

40º nozzle - White. This nozzle delivers a 40 degree spray pattern and a less powerful stream of water. It covers a wide area of cleaning. This nozzle should be used for most general cleaning jobs.

Chemical nozzle - Black. This nozzle is used to apply chemicals or cleaning solutions. It has the least powerful stream.
