PRE-OPERATION

ADJUSTING FAN PATTERN
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 – Adjusting nozzle for fan pattern (not applicable on some nozzle)

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 – Narrow high impact stream

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 – Wide fan pattern

NOZZLE CLEANING INSTRUCTIONS
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:

• Turn off and unplug unit.
• Turn off water supply. Relieve any pressure trapped in the hose by squeezing trigger 2-3 times.
• Separate lance from gun.
• Rotate nozzle to the narrow stream setting. This opens up the fan blades.
• 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 Figure 5.)

Figure 5 – Insert tip cleaner in nozzle hole and move back and forth until debris is dislodged

• 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.

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.

Figure 6 – Optimum angle to cleaning surface

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 CLEANLING 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.
The impact force can be varied by controlling the three
previously noted items. 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 surest way to avoid damaging surfaces is to follow
these steps:

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

TURBO NOZZLE
(NOT INCLUDED WITH ALL MODELS)
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 fan pattern. This swirls the narrow high impact stream into a cone shape that cleans a larger area.

CAUTION: Since 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. Additionally, the turbo nozzle is NOT adjustable and cannot be used to apply detergent.

DETERGENTS
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 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.

OPERATION

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.

1. Surface preparation
Before starting a pressure wash cleaning job, it is important to prepare the surface that is to be cleaned. This is done by cleaning the area of furniture, and making sure that all windows and doors are closed tight. In addition, you should make sure that all plants and trees adjacent to the cleaning area are protected by a drop cloth. This will ensure that your plants won’t be sprayed by the detergents.

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 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.

3. Detergent Application
USE THE INSTRUCTIONS APPROPRIATE FOR MODEL PURCHASED

NOTE: Use only detergents formulated for pressure washes.

NOTE: Test detergent in an inconspicuous area before use.

Figure 7 – Detergend application

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 to 19).

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. ( See Figure 8)

Figure 8 – Attach applicator to gun
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.

4. Final Rinse
Start final rinse at bottom an work upward. Make sure you thoroughly rinse the surface and that all detergent has been removed.

5. Shut down

1. Be sure all detergent is flushed from system.

2. Turn off motor.

3. Turn off water supply.

4. After motor and water supply are turned off, trigger gun to depressurize system.
   CAUTION: NEVER turn water supply off before turning motor off. Serious damage could occur to the pump and or motor.
   WARNING! NEVER disconnect high pressure discharge hose from machine while system is pressurized. To depressurize, turn motor off, turn water supply off and squeeze gun trigger 2-3 times.

5. After each use, wipe all surfaces of the pressure washer with a clean, damp cloth.

6. Storage
Do not store pressure washer outdoors.
Do not store pressure washer where it might freeze.

TIPS FOR EXTENDING THE LIFE OF YOUR PRESSURE WASHER

1. Never operate unit without water.
2. Pressure washer is not meant to pump hot water. Never connect to hot water supply – this will significantly reduce life of the pump.
3. Using detergent other than others brand may cause damage to pump components (o-rings, etc.).This also applies to chemicals such as bleach, dish soap, etc.
4. Never operate unit for more than one (1) minute without spraying water. Resulting heat buildup will damage pump.
5. Before adjusting nozzle’s pressure (high-to-low or lowto-high) release trigger. Failure to do so will reduce life of o-rings in lance.

THE SUCTION FUNCTION
You can connect the high pressure cleaner to the water sources such as taps or pump water from other sources without pressure.

To work with the water supply without pressure the suction hose should be removed from the supply and the gun nozzle should be moved to position “Low” (Figure 14). After that the high pressure cleaner should work idle for a few seconds to drain the excess water and release air. Put the suction hose into the water source. After draining some water the gun nozzle should be moved to position “High” (Figure 14). Now the high pressure cleaner is ready to work under high pressure.
