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 ef

fi

 ciency 

is achieved without damaging the surface.

TURBO NOZZLE
(NOT INCLUDED WITH ALL MODELS)
A turbo nozzle, sometimes referred to as a rotary noz-
zle, is a very effective tool that can signi

fi

 cantly reduce 

cleaning time. The turbo nozzle combines the power of 
a narrow high impact stream and the ef

fi

 ciency 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 ad-
justable and cannot be used to apply detergent.

DETERGENTS
The use of detergents can dramatically reduce clean-
ing time and assist in the removal of dif

fi

 cult  stains. 

Some detergents have been customized for pressure 
washer use on speci

fi

 c cleaning tasks. These deter-

gents 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 apply-
ing 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 up-
ward. 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 combina-
tion with detergents and high pressure rinsing.

OPERATION

The following cleaning procedure will help you to or-
ganize your cleaning task, and ensure that you achieve 
the most bene

fi

 cial 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 im-
portant to prepare the surface that is to be cleaned. 
This is done by cleaning the area of furniture, and mak-
ing 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 wa-

• 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-

fl

 ushing  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 im-
pact 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 prevent-
ing the desired cleaning action.
The optimum angle for spraying water against a clean-
ing surface if 45 degrees.

Figure 6 - Optimum angle to cleaning surface

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

fi

 cial impact force combined with ef-

fi

 cient 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 in-
creased as the nozzle is moved closer to the surface.

HOW TO AVOID DAMAGING SURFACES
Damage to cleaning surfaces occurs because the im-
pact force of the water exceeds the durability of the sur-
face. 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.
