ing time. The turbo nozzle combines the power of a nar-

row 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 im-

pact stream, only use it in applications where the clean-

ing 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 ap

-

proximately as thick as water. The use of thicker deter-

gents, 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 ap-

plied 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 combination 

with detergents and high pressure rinsing.

OPERATION

The following cleaning procedure will help you to organ-

ize 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 pre-

viously listed.

1. Surface preparation

Before starting a pressure wash cleaning job, it is impor-

tant 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 de-

tergents.

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 clean-

ing 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 

•  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 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 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  ef

-

ficient 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 clean-

ing 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 im-

pact 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 clean
