Pressure Washers
Pre-Operation (Continued)
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 CLEANING SURFACE
Another factor that determines the impact force
of the water is the distance from the spray noz-
zle 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 suscepti-
ble 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 dis-
tance to the cleaning surface until optimum
cleaning efficiency is achieved without damag-
ing 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 signifi-
cantly reduce cleaning time. The turbo nozzle

combines the power of a narrow high impact
stream and the efficiency of a 25 degree fan pat-
tern. 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 diffi-
cult stains. Some detergents have been cus-
tomized for pressure washer use on specific
cleaning tasks. These detergents are approxi-
mately as thick as water. The use of thicker
detergents, such as dish soap, will clog the chem-
ical injection system and prevent the application
of the detergent.
The cleaning power of detergents comes from
applying them to a surface and giving the chemi-
cals time to break down the dirt and grime.
Detergents work best when applied at low pres-
sure.
The combination of chemical action and high
pressure rinsing is very effective. On vertical sur-
faces, 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 pres-
sure rinsing.
1. Surface Preparation
Before starting a pressure washer cleaning job, it
is important to prepare the surface that is to be
cleaned. This is done by clearing the area of fur-
niture, and making sure that all windows and
