How To Avoid Damaging Surfaces - VITO PRO-POWER POWERWASH 150 HQ Manual De Instrucciones

Angle to the cleaning surfure:
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 preventing the
desired cleaning action.
The optimum angle for spraying
water against a cleaning surface is
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.

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.

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.
Avoid spraying windows with a
narrow high impact stream or turbo
22
nozzle as this may cause breakage
The surest way to avoid damaging
surfaces is to follow these steps:
Before triggering the gun, adjust the
nozzle to a wide fan pattern.
Place the nozzle approximately
4-5 feet from and 45 degrees
to the cleaning surface, and trigger
the gun.
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.

With detergents, this machine has a
detergent flow rate regulator.
Turn to the right for more detergent.
To have detergent along with the
water, the nozzle must be in the low
pressure position, so turn the nozzle
ring conterclockwise and the water.
Will flow almost without pressure
and with detergent.
Turn clockwise to revease the water
pressure.
noTE: Test detergent in an
inconspicuous area before use.
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
