Connecting washer parts

The washer has a side-mounted holster that holds the gun/lance neatly in place for storage. This is assembled by sliding the top clasp (fig. 2) onto the mounting point (fig. 1)
A lower retainer holds the end of the gun/lance securely. This is attached by sliding the lower cup (fig. 4) onto the mounting point at the base of the washer (fig. 3)

The front lower handle provides a convenient point to grip when transporting your washer and also serves as additional stability when upright. To attach, insert the handle ‘A’ into the sockets ‘B’ at the lower front of the machine. Fix in place on the under-side with the two screws provided.

Hints for getting started

Automatic On / Off:
The motor on this pressure washer does not run continuously. It only runs when the trigger of the spray gun is squeezed.

Bleeding the gun:
It is very important to bleed the gun before and after using the pressure washer.
Squeeze the trigger to allow any air that is trapped inside of the unit and hose to escape. Continue to squeeze the trigger until a steady stream of water comes from the nozzle. (This process may take up to 2 minutes).
This will prevent freezing in cold temperatures and damage to the machine and the gun.

Accessory connections

The RX525i has a variety of cleaning attachments designed for specific uses. The following describes the connection and intended use of the supplied accessories.

The Patio Cleaner attaches with the extension to the gun. The patio cleaner is used to clean flat surfaces specifically, but not limited to, patios. The design ensures a contained area of cleaning with very little over-spray. The rotating jet nozzles inside should not be touched whilst connected under any circumstances.

The Rotary Brush screws directly into the gun. The brush will rotate using the flow of water to allow for a more thorough clean.

The Straight Brush screws directly into the gun. It operates similar to the rotary brush but with no moving parts. This gives a more delicate clean.

The Turbo Wand screws directly into the gun. It creates a powerful cone of water that has tremendous cleaning power. The combination of high pressure, spun by the
the ceramic bearing will produce a very high pressure/cleaning area combination.

The Curved Gutter Lance screws directly into the gun.
It provides a convenient curve to the jet spray using the supplied nozzles to clean those hard-to-reach places.

The supplied nozzles attach to the lance that screws into the gun. These provide a variety of pressures and patterns designed for different cleaning applications.

Nozzles

The nozzles are stored in a panel mounted to the handle of the washer.

Red 0°Nozzle: This nozzle delivers a pinpoint stream of pressurized water and is extremely powerful. It should only be directed at surfaces that can withstand high pressure such as metal or concrete. (Fig. 14)

Yellow 15° Nozzle: This nozzle delivers a powerful 15-degree spray pattern for intense cleaning of small areas. This nozzle should only be used on areas and materials that can withstand very high pressure. (Fig. 15)

Green 25° Nozzle: 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 very high pressure. (Fig. 16)

White 40° Nozzle: This nozzle delivers a 40-degree spray pattern and a less powerful stream of water. This nozzle can cover a wide area and can be used for most general cleaning jobs. (Fig. 17)

Black / Blue Detergent Nozzle: This nozzle is used to apply detergent and cleaning solutions. This nozzle produces the weakest pressure of the three nozzles. Don’t forget that you can adjust the detergent flow using the dial on the front of the machine. (Fig. 18)

To avoid damaging your cleaning surface, always start with the lowest pressure nozzle and work up through to the higher pressure nozzles.

Nozzle Maintenance

A clogged or partially clogged nozzle can significantly reduce water flow and cause the unit to pulsate while spraying. To clean the nozzle:

1. Turn off and unplug the unit from the electric mains.
2. Turn off the water supply and relieve any pressure trapped in the hose by squeezing the gun trigger 2-3 times.
3. Separate lance from the gun.
4. Rotate the nozzle to the narrow high-impact stream setting. This opens up the fan blades.
5. Using the included tip cleaner, or an unfolded paper clip, insert the wire into the nozzle hole and move back and forth until any debris is dislodged.
6. Remove additional debris by back-flushing water through the nozzle. To do this, place the end of a garden hose (with water running) to the end of the nozzle for 30-60 seconds.

WARNING: Do not use the machine if the supply cord or any important parts of the machine are damaged (e.g. safety devices, high-pressure hoses, etc).

Using your Washer

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 embed in the surface, thereby preventing the desired cleaning action.

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

Optimum cleaning angle of 45°

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.

Avoid Damaging Surfaces

Damage to 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.

The surest way to avoid damaging surfaces:

1. Adjust the nozzle to a wide spray pattern.
2. Place the nozzle approximately 4-5 feet from and 45 degrees to the cleaning surface.
3. Vary the spray pattern, spray angle, and distance to the cleaning surface until optimum cleaning efficiency is achieved without damaging the surface.

Turbo Nozzle
A turbo nozzle sometimes referred to as a rotary 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 spray pattern. This swirls the narrow high-impact stream into a cone shape that cleans a larger area.

A turbo nozzle uses a narrow high impact stream so only use it in applications where the cleaning surface cannot be damaged by a narrow high impact spray. The turbo nozzle is not adjustable and cannot be used to apply detergent.

Detergent

The use of detergents can dramatically reduce cleaning time and assist in the removal of difficult stains. Some detergents have been customized for pressure washer use. The use of thick detergents such as dish soap, will clog the chemical injection system and prevent the application of the detergent. Furthermore, the salt/acid content can cause
irreparable corrosion to the internal components of the washer and pump.

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 particularly tough stains, it may be necessary to use a brush in combination with detergents and high-pressure rinsing.

Operation
The following cleaning procedure will ensure that you achieve the most beneficial results in the shortest amount of time.

1. Surface preparation
   Clear the working area and make sure that all windows and doors are closed tightly. Make sure that all plants and trees adjacent to the cleaning area are protected by a drop cloth.

2. Initial high-pressure rinse
   The next step is to 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 dirt that has worked its way into the cleaning surface. Before triggering the gun, adjust the nozzle to a wide spray pattern and slowly adjust to the desired spray pattern. This will help you avoid applying too much pressure to the surface that could cause damage.

3. Detergent application
   Only use detergents formulated for pressure washers. Test the detergent in an inconspicuous area before use.

Follow the manufacturer’s label directions for mixing the correct concentrations of detergent to the water.

1. Apply the detergent so it thoroughly covers the cleaning surface. Apply from bottom to top to prevent the detergent from sliding down and streaking.
2. Allow the 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.
3.  Remove the detergent applicator from the gun and replace it with the lance.
4. Rinse detergent from the surface.
5. Rinse the detergent applicator with clean water following each use.

5. Final rinse
Make sure you thoroughly rinse the surface and that all detergent has been removed.

6. Shut down

1. Make sure all detergent is flushed from the system.
2. Turn off the motor.
3.  Turn off the water supply.
4. Trigger the gun to de-pressurize the system.
5. After each use, wipe all surfaces of the pressure washer with a clean, damp cloth.

Looking After your Product

1. This pressure washer is not meant to pump hot water. Never connect to a hot water supply.
2. Never operate the unit for more than one minute without spraying water. This will cause a heat build-up that can damage the pump.
3. Only use the nozzles supplied with the machine.
4. Never store the pressure washer outdoors or where it could freeze. The pump will be seriously damaged. Any components with water left inside will also be damaged, e.g. the pressure gun.
5. Release the trigger when changing the spray pattern. Failure to do so could result in damage.
6. Do not operate the pressure washer with the inlet water screen removed. Be sure to keep the screen clear of debris and sediment.
7. Make sure you clean the machine every three months and inspect the filter and the nozzle prior to every use, ensuring there is no debris that may impair use.
