OPERATION

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 recircu-

lating 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. NOTE: Any supply pressure or delivery rate less than this will not allow the pressure washer to operate at its full potential.

OPERATING FEATURES OF YOUR PRESSURE WASHER

BYPASS MODE

During normal operation 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.

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

DO NOT attempt to increase pump pressure. A higher pressure setting than the factory set pressure will damage pump.

The pressure output of the pump is preset at the factory to achieve optimum pressure and cleaning. If you need to lower the pressure, it can be accomplished by one of these three methods:

1. Back away from the surface being cleaned. The farther away you are, the less pressure is delivered to the surface being cleaned.

2. Adjust the pressure regulator knob on the pump.

a. Turn the pressure regulator knob counter-

clockwise.

b. Once you have finished using your pressure

washer, return the pressure regulator knob to its original position by turning it clockwise until it stops.

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

Pressure Regulator Knob

THERMAL RELIEF VALVE

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.

3. Reduce the speed of the gasoline engine (RPM). Slow engine down and water pressure will go down with it.

SPRAY NOZZLES

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.

9 — ENG

D20249

PRESSURE WASHER BASICS

OPERATION

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

NOTE

A nozzle is easier to remove from its receptacle if it is pushed from underneath while it is being pulled from above.

RISK OF INJECTION OR INJURY TO PERSON. DO NOT DIRECT DISCHARGE STREAM TOWARD PERSONS.

WHEN USING THE HIGH PRESSURE NOZZLES, DO NOT ALLOW THE JET-LIKE SPRAY TO COME IN CONTACT WITH UNPROTECTED SKIN, EYES, OR WITH ANY PETS OR ANIMALS. SERIOUS IN-

JURY CAN OCCUR.

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.

CHANGING NOZZLES

DO NOT attempt to change nozzles while pressure washer is running. Turn engine off before changing nozzles.

To ensure efficient operation and longer life of your pressure washer, a routine maintenance schedule should be prepared and followed. The following routine maintenance schedule is geared to an unit in a normal working environment. If necessary, the schedule should be modified to suit the conditions under which your pressure washer is used. The modifications will depend upon the hours of operation and the working environment. If the pressure washer is in an extremely dirty and/or hostile environment it will require a greater frequency of all maintenance checks.

ENGINE

1. Consult Engine Owner's Manual for manufacturer's recommendations for any and all engine maintenance.

PUMP

The Annovi Reverberi (AR) pump on your pressure washer was shipped from the factory with oil. The oil in your pump must be changed after the first 10 hours of use and every 50 hours thereafter.

To Check Oil:

Oil Fill Plug

Bottom Drain Plug (underneath pump)

1. For units with sight glass:

a. If oil level is low, add oil so oil level is midway

between high and low marks on sight glass.

b. If oil level is high, remove excess oil so oil level

is midway between high and low marks on sight glass.

2. For units with dipstick:

a. Remove dipstick from pump and wipe clean.

b. Insert dipstick fully into pump, then remove it.

c. Oil level is correct when oil covers the lower 1/2

inch of end of dipstick.

To Change Oil:

1. Remove drain plug using one of the methods

below:

a. If your AR pump has a side drain plug, use a

17 mm wrench to remove the plug and drain the pump.

Sight Glass

Side Drain Plug

b. If your AR pump does not have a side drain

plug, drain the pump by removing the bottom drain plug on the underside of the pump with an 8 mm Allen wrench.

2. Drain oil into a suitable container.

3. Replace oil drain plug and tighten securely.

4. Remove oil fill plug (or dipstick).

5. Add 18.5 oz of 30W non-detergent oil to pump.

6. Replace oil fill plug and tighten securely.

HOW TO CLEAN THE NOZZLES

If a spray nozzle becomes clogged with foreign material such as dirt, excessive pump pressure may develop and the spray pattern will change. If a nozzle becomes partially clogged or restricted, the pump pressure will pulsate. If this happens, clean the nozzle immediately using the nozzle cleaning kit supplied with your pressure washer. The procedure is as follows:

1. Shut off pressure washer and turn off water supply.

2. Pull trigger on spray gun to relieve any water pressure.

3. Disconnect quick connect wand from spray gun.

4. Remove nozzle from wand.

5. Inspect nozzle for obstructions, grime, or any foreign matter that could restrict flow of water.

6. Remove any obstructions with nozzle cleaning tools provided and back flush with clean water.

7. Direct water supply into nozzle end for 30 seconds to back flush loosened particles.

8. Take this opportunity to inspect wand for obstructions. Back flush wand if obstructions are seen.

9. Reassemble nozzle to wand.

10. Reconnect wand to spray gun and turn on water supply.

11. Start pressure washer and test spray pattern. See Nozzles in Operation section.

12. If spray pattern is still incorrect, replace nozzle.

MAINTENANCE

HOW TO CLEAN THE WATER INLET FILTER

This screen filter should be checked periodically and cleaned if necessary.

1. Remove filter by grasping end and removing it from water inlet of pump as shown.

2. Clean filter by flushing it with water on both sides.

3. Install filter into water inlet of pump.

STORAGE

PREPARATION FOR STORAGE

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. Remove gasoline from engine or add fuel stabilizer, such as "Sta-Bil" to gasoline to prevent gumming

2. If you are adding fuel stabilizer, connect water supply and high pressure hose to pump and spray gun.

3. Turn water supply on and start engine.

4. Squeeze spray gun trigger while engine is running to avoid operating pump in ""bypass mode"".

5. Run engine for five minutes, then shut engine off.

6. Disconnect water supply.

7. Disconnect spark plug wire and remove spark plug.

8. Pour one teaspoon of engine oil into spark plug hole.

9. Place a rag over the spark plug hole and pull starter rope slowly several times to lubricate internal cylinder wall.

PUMP

NOTE: If storing the unit for more than 30 days RV antifreeze needs to be ran 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 environment. 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 high pressure hose from pump and from spray gun.

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

4, Add RV antifreeze to hose as shown.

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

6. Remove short hose from water inlet of pump.

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

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

9. Drain all water from spray gun and wand by holding spray gun in a vertical position with nozzle end pointing down and squeezing trigger. Store in cradle on pressure washer handle.

10. Store nozzles in color matching receptacles on flat panel of pressure washer handle.

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