5.4 Working methods
Your high pressure washer has
been developed for cleaning
according to the so-called
»2-step method«.
However, your high pressure
washer must be equipped
with an external detergent
injector.
STEP 1
Application of detergent
STEP 2
High pressure cleaning
In practice the working process
is laid down in accordance with
the actual job, but as a starting
point the following working
method can be described for a
job:
1. Apply detergent under low
pressure. The dosage is
chosen according to the
job which is to be carried
through, and the adjustment
is made on the dosing unit.
2. Await acting time. Let the
detergent act on the dirt/
surface for a short time
prior to pressure cleaning -
usually a few minutes.
3. High pressure cleaning.
Clean all surfaces under
high pressure.
4. Rinse afterwards, if
necessary. To make sure
that residual impurities are
removed from the surface.
In connection with the working
process the optimum cleaning
will be reached by following
these 3 pieces of advice:
Advice no. 1
When using a detergent,
usually always apply it on a
dry surface. If the surface is
rinsed with water at first, it may
be difficult for it to absorb the
detergent, and the result is a
reduced effect of the detergent.
Advice no. 2
When applying a detergent
on large vertical surfaces (i.e.
the sides of a truck) work from
below and upwards. Thus you
will avoid the detergent running
off the surface through grooves
and dark streaks appearing on
the surface whilst cleaning.
Advice no. 3
During the high pressure
cleaning you should work so
that the high pressure water
does not run over the surface
which has not been cleaned
yet. This is to ensure that there
is sufficient detergent on the
surface when the high pressure
water hits the surface.
