Surface Preparation; Initial High Pressure Rinse - Campbell Hausfeld PW1810 Instrucciones De Funcionamiento Y Manual De Piezas

To clean out the nozzle:
• Turn off unit.
• Turn off water supply. Relieve any
pressure trapped in the hose by
squeezing trigger 2-3 times.
• Separate quick connect nozzle
from lance.
• Rotate nozzle to the narrow
stream setting. This opens up the
fan blades.
• Using the included tip cleaner, or
an un-folded paper clip, insert
wire into the nozzle hole and
move back and forth until debris
is dislodged (refer to Figure 11).

• Remove additional debris by
back-flushing water through the
nozzle. To do this, remove nozzle
from lance, place end of a garden
hose (with water running) to tip
of nozzle pushing water and
debris out the back opening of
the nozzle.
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.
Tip Cleaner
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.

1. Surface Preparation

Before starting a pressure washer
cleaning job, it is important to prepare
the surface that is to be cleaned. This is
done by clearing 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.

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
