Spraying water against a surface at this angle provides for the most beneficial impact force combi-
ned 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.
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 deter-
gent from sliding down and causing streaks. High pressure rinsing should also progress from
the bottom to top. On particularly toughstains, it may be necessary to use a brushin combination
