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.
( See Figure2)
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.
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.
NOZZLE CLEANING INSTRUCTI-ONS
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.)
• 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.
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.

ADJUSTABLE SPRAY NOZZLE
Turn off the spray lance first, hold the rear part of spray nozzle, then turn the front part of spray nozzle
clockwise, Water may be sprayed out from the spray nozzle in fan shapes (fig 1); Turn the front part of spray
nozzle withershins, Water may be sprayed out from the spray nozzle linearly (fig 2).
Low/High Pressure Adjustable Lance
Using High Pressure:
Please make sure the trigger released and there is not any water spraying. then turn the rear part of spray
nozzle withershins ( fig 4). Squeeze the trigger, the gun will spray water with high pressure.
Using low pressure:
Please make sure the trigger released and there is not any water spraying. then turn the rear part of spray
nozzle clockwise ( fig 3). Squeeze the trigger, the gun will spray water with low pressure.
CAUTION: Selection of high or low pressure by turning action. The selection of the pressure must be carried
out with the gun in closed position.
WATER INLET SCREEN
The water inlet filter must be inspected regularly, so as to avoid blockage and restriction in the water supply
to the pump (fig 5).
USING DETERGENT
Add detergent to the container. Set the Adjustable Spray Wand at low pressure position.
Trigger gun to spray 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. Final Rinse
start final rinse at bottom an work upward. Make sure you thoroughly rinse the surface and that all
detergent has been removed.
4. 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.
