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.
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 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 organize 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 previously
listed.
1. Surface preparation
Before starting a pressure wash cleaning job, it is important 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 detergents.
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 cleaning 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.
