Nozzle Selection

NOTE! Some portable pressure washers come with five nozzle attachments for different uses. Refer to

the diagram (below) and on the pressure washer itself to see which nozzle is applicable for your

purpose.

Turbo Nozzle (if equipped)

A turbo nozzle is a very effective tool that can significantly reduce cleaning time.

The turbo nozzle combines the power of a narrow high impact stream and the

efficiency of a 25-degree fan pattern. This swirls the narrow high impact stream

into a cone shape that cleans a larger area.

CAUTION! A turbo nozzle uses a narrow high impact stream; only use it in

applications where the cleaning surface cannot be damaged by narrow

high impact spray. The turbo nozzle is NOT adjustable and cannot be

used to apply detergent.

Twist-Adjustable Nozzle (if equipped)

The angle of spray coming out of the lance may be adjusted on some

lances by rotating the nozzle. This will vary the spray pattern from

approximately a 0° narrow high impact stream to a 60° wide fan spray

(Figure 2).

A narrow stream has high impact force on the cleaning surface and

results in maximum deep cleaning in a concentrated area. However, this

narrow high impact spray must be used cautiously, as it may damage

some surfaces (figure 3).

JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA JET USA

RX470 Electric Pressure Washer

A wide fan pattern will distribute the impact of the water over a larger

area, resulting in excellent cleaning action with a reduced risk of surface

damage, large surface areas can be cleaned more quickly using a wide

fan pattern (figure 4).

Angle to the Cleaning Surface

When spraying water against a surface, maximum impact is generated when the

water strikes the surface “head on.” However, this type of impact tends to cause

dirt particles to imbed in the surface, thereby preventing the desired cleaning

action.

The optimum angle for spraying water against a cleaning surface if 45 degrees.

Spraying water against a surface at this angle provides for the most beneficial

impact force combined with efficient removal of debris from the surface.

Distance from cleaning surface

Another factor that determines the impact force of the water is the distance from the spray nozzle to the cleaning

surface. The impact force of the water is increased as the nozzle is moved closer to the surface.

How to Avoid Damaging Surfaces

Damage to cleaning surfaces occurs because the impact force of the water exceeds the durability of the surface.

Never use a narrow high impact stream or a turbo/rotary nozzle on a surface that is susceptible to damage.

Avoid spraying windows with a narrow high impact stream or turbo nozzle as this may cause breakage.

The recommended way to avoid damaging surfaces is as follows:

•

Before triggering the gun, adjust the nozzle to a wide fan pattern.

•

Place the nozzle approximately 4-5 feet from and 45 degrees to the cleaning surface and trigger the gun.

•

Vary the fan pattern spray angle and the distance to the cleaning surface until optimum cleaning efficiency is

achieved without damaging the surface.

Detergents

The use of detergents can dramatically reduce cleaning time and assist in the removal of difficult stains. Some

detergents have been customised for pressure washer use on specific cleaning tasks. These detergents are

approximately as thick as water. The use of thicker detergents, such as dish soap, will clog the chemical

injection system and prevent the application of the detergent. The cleaning power of detergents comes from

applying them to a surface and giving the chemicals time to break down the dirt and grime. Detergents work best

when applied at low pressure. The combination of chemical action and high-pressure rinsing is very effective. On

vertical surfaces, apply the detergent starting at the bottom and work your way upward. This will prevent the

detergent from sliding down and causing streaks. High pressure rinsing should also progress from the bottom to

top. On particularly tough stains, it may be necessary to use a brush in combination with detergents and high

pressure rinsing.

The following cleaning procedure will help you to organize your cleaning task and ensure that you achieve the

most beneficial results in the shortest amount of time. Remember to use the spraying/cleaning techniques

previously listed.

Detergent Application

IMPORTANT! Only use the instructions appropriate for model purchased.

NOTE! Use only detergents formulated for pressure washes.

NOTE! Test detergent in an inconspicuous area before use.

For Units with Detergent Applicator Included: follow manufacturer’s label

directions for mixing correct concentrations of detergent to water ratio through

the pressure washer is approximately 5.4% (1 part detergent to 19 parts water).

NOTE! Some pressure washers have a built-in detergent container, others

have a separate gun attachment for this purpose.

1. Unscrew to top of detergent applicator and fill applicator with detergent.

2. Replace top on applicator.

3. Remove lance from gun.

4. Attach detergent applicator to gun, if equipped (See below).

5. Apply detergent so it thoroughly covers cleaning surface. Apply from bottom to top to prevent detergent from

sliding down and streaking.

6. Allow detergent to remain on the surface for a few minutes. This is a good time to use a brush to lightly scrub

heavily soiled areas. Never allow detergent to dry on the cleaning surface.

7. Remove detergent applicator from gun and replace with the lance or remove applicator from end of lance.

8. Rinse detergent from surface.

NOTE! Flush detergent applicator with clear water following each use.

Initial High-Pressure Rinse

Spray the cleaning surface with water to clear off any dirt or grime that may have collected on the surface. This

will allow your detergent to attack the deep-down dirt that has worked its way into the cleaning surface. Before

triggering the gun, adjust the nozzle to a wide fan pattern and slowly adjust to the desired spray pattern. This will

help you avoid applying too much concentrated spray to the surface which could cause damage.

Final Rinse

Start final rinse from the bottom of your item and work your way upward. Make sure you thoroughly rinse the

surface, and that all detergent has been removed.

1. Shut down

2. Be sure all detergent is flushed from system.

3. Turn off motor.

Storage

Do not store pressure washer outdoors or where it might freeze.

Tips for extending the life of your pressure washer.

•

Never operate unit without water.

•

Pressure washer is not meant to pump hot water. Never connect to warm water supply – this will significantly

reduce life of the pump.

•

Using the wrong detergent other than recommended may cause damage to pump components (O-rings,

etc.). This also applies to chemicals such as bleach, dish soap, etc.

•

Before adjusting a nozzles pressure (high-to-low or low-to-high) release trigger. Failure to do so will reduce

life of O-rings in lance.

NOTE! When the pressure washer is not being operated or is being stored more than one month, it is

recommended that you turn off and disconnect the power.

Nozzle Cleaning Instructions

NOTE! A clogged or partially clogged nozzle can cause a significant reduction of water coming out of

the nozzle and cause the unit to pulsate while spraying.

To clean out the nozzle:

1. Turn off and unplug unit.

2. Turn off water supply. Relieve any pressure trapped in the hose by

squeezing trigger 2-3 times.

3. Separate lance from gun.

4. Rotate nozzle to the narrow stream setting. This opens up the fan

blades.

5. Using included tip cleaner, or an unfolded paper clip, insert wire into the nozzle hole and move back and

forth until debris is dislodged. (See image)

6. Remove additional debris by back-flushing water through the nozzle. To do this, place end of a garden hose

(with water running) to end of nozzle for 30-60 seconds.

Water Screen

Some pressure washers are equipped with a water inlet screen to protect the pump. If the screen is not kept

clean, it will restrict the flow of water to the pressure washer and may cause damage to the pump.

•

The screen is fragile so be careful when cleaning or removing it. Any foreign particles entering the pump

may damage it.

•

Do not operate the pressure washer without the screen in place (if originally equipped.)

•

Remove the screen and backflush to remove impurities from the screen.

•

Replace afterwards immediately.

Hose Care

To extend your hose life, you’ll want to drain the hose after use. Don’t rely on the nozzle to cut the water when

you are done. If you do, the water pressure builds up inside the hose and can burst it. The better procedure for

the hose upkeep is to turn off the water at the spigot and allow the hose to drain.

Another way to keep your hose in good shape for longer is to avoid dragging it by the spray trigger assembly.

This weakens the coupler connection and causes leaks.

Also, don’t just leave it in a pile when you are finished with it. Using the included hose reel prevents kinks that

create tears.

Finally, there is the issue of storing a hose over winter. If you live in a cold winter region, you’ll want to bring the

hose into the garage (or somewhere inside) to prevent freezing. Drain the entire hose first, then coil it on a hose

reel and carry it inside.
