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
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
-9-
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.
TIPS FOR EXTENDING THE LIFE OF
YOUR PRESSURE WASHER
1. Never operate the unit without water.
2. This pressure washer is not
designed to pump hot water. Never
connect it to the hot water supply –
this will significantly reduce the life of
the pump.
3. Only use detergents specifically
designed for pressure washers.
Other types of detergent may cause
internal damage to the unit, as might
chemicals such as bleach,
washing-up liquid, etc.
4. Never operate the unit for more than
one (1) minute without spraying
water. Otherwise, the resulting heat
buildup will damage the pump.
5. Winter Storage:
For storage during the winter months
we recommend the use of a solution
of 50/50 mix of antifreeze and water.
This will keep the pump from
freezing and getting damaged and
will protect the internal components.
Method: You will need a length of
garden hose and a funnel. Attach the
garden hose to the inlet and pour the
antifreeze into the unit via the funnel.
Switch the unit on for a few seconds
to allow the solution to flow through
the system. Disconnect your
pressure washer from the mains
power, then pack away in your
storage area.
WARNING: Before reusing completely
flush the unit out with plain water.
Anti-freeze can damage paintwork so
you must ensure there is no anti-freeze
left in the system before using it again.
