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 wand.

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

Wand:

Multi-Reg wand: Has a spray nozzle which adjust from a pencil stream (0°) to a wide angle fan spray

(60°). The spray can be adjusted by twisting the nozzle clockwise and/or counterclockwise.

Also, the high and low pressure settings can be controlled by moving the nozzle in and out. See

Operation section.

Quick Connect: This type of lance is equipped with a female quick connect coupler on the end.

This allows the user to quickly change out highpressure nozzles for different spray patterns and change to the soap nozzle for low pressure and chemical/soap applications.

See Operation section.

Chemical Hose: Allows cleaners or cleaning solvents to be mixed with the pressurized water stream. See

How To Siphon Chemicals/Cleaning Solvents in

Operation section of this manual.

BASIC ELEMENTS OF ENGINE

Choke Control (if equipped): Opens and closes the choke valve in carburetor.

Primer Button (if equipped): Primes carburetor with fuel.

Throttle Control Lever: Controls engine speed.

Starter Grip: Pulling starter grip operates recoil starter to crank engine.

Fuel Valve Lever (if equipped): Opens and closes connection between fuel tank and carburetor.

Engine Switch (if equipped): Enables and disables ignition system.

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 through the pressure washer.

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.

Chemical Injection: Feeds cleaning agents into the pump to mix with the pressurized water and help in cleaning.

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.

this will not allow the pressure washer to operate at its full potential and may cause damage to the pump.

Any supply pressure or delivery rate less than

PRESSURE WASHER OPERATING

FEATURES

Bypass

Mode

During normal operation the water supply is turned on, engine is running, spray gun trigger is depressed, and the cold water supply circulates inside the pressure washer pump allowing pump to maintain a safe operating temperature.

When you release spray gun trigger and engine is still running, you are in bypass mode.

When unit is in bypass mode, water circulating inside the pump begins to heat up. If unit is left in bypass mode for more than two (2) minutes, the water temperature will rise to a dangerous level and damage internal components of the pump.

If pressure washer is operated without an adequate water supply or operated for more than two (2) minutes without depressing the spray gun trigger, the pump will overheat and be seriously damaged. Any damage to pump due to these causes will not be covered under warranty.

Chemical Flow Adjustment

Some pumps are equipped with an adjustable chemical injector as shown here. Turn the chemical adjustment knob counterclockwise to increase the amount of chemical used and clockwise to decrease the amount of chemical used. If the knob is turned clockwise until it stops, the chemical injector will close and will not draw any chemicals/soaps.

9 -- ENG

Thermal

Relief

VaJve

In an effort to prevent 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.

DO

NOT allow your unit to operate

in bypass mode for more than two minutes at any time.

Overheating of pump will cause damage to pump.

Pressure Adjustment

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 sudace to be cleaned.

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

2.

Reduce the speed of the gasoline engine (RPM).

Slow the engine down and the water pressure will go down with it.

Step 3 is only for models without an automatic pressure regulator.

3.

Adjust the pressure regulator on the pump.

Turn 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.

HOW TO USE WAND

See the Box Contents to determine if your unit is equipped with a multi-reg or quick connect wand.

For Multi=Reg Wands:

Your pressure washer is equipped with a multi-reg wand with both high and low pressure settings.

The high pressure setting is for cleaning and rinsing, the low pressure setting is for applying chemicals or cleaning solutions to surfaces.

It is recommended that you follow these steps to protect the internal seals of the pressure washer when

storing the unit for an extended period and WHEN

FREEZING TEMPERATURES ARE EXPECTED.

ENGINE

1.

Consult the Engine Owners Manual for the manufacturer's recommendations for storage.

PUMP

NOTE: If storing the unit for more than 30 days RV antifreeze needs to be run through the pump. This

helps prevent damage within the pump head. RV antifreeze is not only added for winterizing, but for

proper lubrication regardless of temperature or en-

vironment. Storing the pump less than 30 days does not require the RV antifreeze.

1.

Obtain a funnel, six ounces of RV antifreeze, and approximately 12 inches of garden hose with a male hose connector attached to one end.

Use only RV antifreeze.

Any other antifreeze

is

corrosive and can damage

pump.

2.

Disconnect spark plug wire.

3.

Disconnect high pressure hose from pump and from spray gun.

4.

Connect 12 inch length of hose to water inlet of pump.

5.

Add RV antifreeze to hose as shown.

6.

Pull engine starter rope slowly several times until antifreeze comes out of high pressure hose connection of pump.

7.

Remove short hose from water inlet of pump.

8.

Install spark plug into spark plug hole and tighten securely, then reconnect spark plug wire.

9.

Drain all water from high pressure hose, coil it, and store it in cradle of the pressure washer handle.

10. Drain all water from spray gun and wand by hold-

ing spray gun in a vertical position with nozzle end pointing down and squeezing trigger. Store in gun/hose holder.

11. Store chemical hose, high pressure hose, spray gun, and wand so they are protected from damage, such as being run over.
