TURBO NOZZLE (NOT INCLUDED WITH
ALL MODELS)

A turbo nozzle, sometimes referred to as
a rotary nozzle, can significantly reduce
cleaning time. The turbo nozzle combines
the power of a narrow high impact
stream with the efficiency of a 25 degree
fan pattern. The turbo nozzle swirls a nar-
row high impact stream into a cone
shape to clean a larger area. 

Since a turbo nozzle
uses a narrow high

impact stream, only use a turbo lance in
applications where the cleaning surface
cannot be damaged by narrow high
impact spray. The turbo nozzle is NOT
adjustable and cannot be used to apply
detergent.

USE THE INSTRUCTIONS APPROPRIATE
FOR MODEL PURCHASED

NOTE

: Use only detergents formulated

for pressure washers.

NOTE

: Test detergent in an inconspicuous

area before use.

Never slide the

nozzle from low to

high pressure or from high to low pres-
sure when the gun is triggered.

Never replace quick 
connect tip when gun

is triggered.

DETERGENTS

The use of detergents can dramatically
reduce cleaning time and assist in the
removal of difficult stains. Many deter-
gents are customized for pressure washer
use on specific cleaning tasks. Pressure
washer detergents are as thick as water.
Using thicker detergents – like dish soap –
will clog the chemical injection system
and prevent the application of the deter-
gent.  
Once applied to a cleaning surface, deter-
gents take time to break down dirt and
grime. Detergents work best when
applied at low pressure. 

You can effectively clean surfaces by com-
bining the chemical action of detergents
with high pressure rinses. On vertical sur-
faces, apply the detergent starting at the
bottom and work your way upward. This
method prevents the detergent from slid-
ing down and causing streaks. Begin high
pressure rinsing at the bottom and work
your way upward. On particularly tough

stains, use a brush in combination with
detergents and high pressure rinsing. 

A. MODELS WITH DETERGENT TANKS

Some gasoline powered units are
equipped with detergent tanks.

If your unit has a detergent tank:

1. Follow manufacturer’s label direc-

tions for mixing correct concentra-
tions of soap/detergents. The soap
detergent to water ratio through
the pump is approximately 10% (1
to 10).

2. Pour detergent into the detergent

tank. The tank capacity is 1.5 gal-
lons.

3a. Place hand around the 3.5” spraying

end section of the lance (the section
that turns from left to right). Pull
firmly and quickly away from you.
(

NOTE: 

Do not adjust lance while

spraying.) The lance will extend 1/2”
and be in low pressure (see Figure
20). Soap can only be drawn in low
pressure.

3b. For units with quick connect tips:

use the black 65

quick connect

spray tip (See Figure 19).

B. MODELS WITHOUT DETERGENT
TANKS

Some gasoline powered units are not
equipped with detergent tanks.

If your unit does not have a detergent
tank:

1. Follow manufacturer’s label direc-

tions for mixing correct concentra-
tions of soap/detergents. The soap
detergent to water ratio through
the pump is approximately 10% (1
to 10).

2. Insert the filter end of the clear

plastic detergent tube into the
detergent container.

3a. Place hand around the 3.5” spray-

ing end section of the lance (the
section that turns from left to
right). Pull firmly and quickly away
from you. (

NOTE: 

Do not adjust

lance while spraying.) The lance will
extend 1/2” and be in low pressure
(See Figure 20). Soap can only be
drawn in low pressure.

3b. For units with quick connect tips:

use the black 65

o  

quick connect

spray tip (see Figure 19).

GENERAL CLEANING TIPS

1. Apply the detergent so that it thor-

oughly covers the cleaning surface.
Apply the detergent from bottom to
top to prevent the detergent from
sliding down and streaking. Wait a
couple of minutes for the detergent
to break down the dirt and grime.
Use a brush to lightly scrub heavily
