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:
f Before triggering the gun, adjust the nozzle to a wide
fan pattern.
f Place the nozzle approximately 4-5 (13-16 cm) feet
from and 45 degrees to the cleaning surface, and
trigger the gun.
f 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.
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
suface. This will allow your detegent 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
