HOW TO AVOID DAMAGING SURFACES
Damage to cleaning surfaces occurs because the
impact force of the water exceeds the durability
of the surface. 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.
Follow these simple steps to avoid damaging your
surfaces:
Before triggering the gun, adjust the nozzle to a
1.
wide fan pattern.
Place the nozzle approximately 4-5 feet
2.
cleaning surface and begin spraying.
Vary the fan pattern spray angle and the
3.
distance to the cleaning surface until optimum
cleaning efficiency is achieved without
damaging the surface.
WATER INLET FILTER
The water inlet filter must be inspected regularly,
so as to avoid blockage and restriction in the water
supply to the pump (Fig 15).
USING DETERGENT
Add detergent to the container and replace the
cap. Do not overfill.
Set the adjustable lance at low pressure (Fig 10).
Depress the trigger to spray detergent.
Note; the detergent does not work on high
pressure.
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 for specific cleaning tasks. These
detergents are approximately as thick as water.
The use of thicker detergents, such as washing-up
liquid, 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. Follow this with a high pressure rinse for
best cleaning results. On vertical surfaces, apply
the detergent starting at the bottom and work your
way upward. This will prevent the detergent form
sliding down and causing streaks. High pressure
rinsing should also progress from the bottom
upwards. 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
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
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. 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.
