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
