• 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 impact 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 preven-
ting the desired cleaning action.
The optimum angle for spraying water against a cleaning surface if 45 degrees.
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 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.
