5.6 Working methods
Original Instructions
Your high pressure hot water
washer has been developed for
cleaning according to the so-
called »2-step method«.
However, your high pressure
hot water washer must be
equipped with an external
detergent injector.
STEP 1
Application of detergent -soaking.
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 me-
thod 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/sur-
face for a short time prior to
pressure cleaning - usually a
few minutes.
3. High pressure cleaning. Cle-
an all surfaces under high
pressure.
4. Rinse afterwards, if neces-
sary. To make sure that resi-
dual 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, usual-
ly always apply it on a dry sur-
face. If the surface is rinsed with
water at fi rst, it may be diffi cult
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 clea-
ning 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 suffi -
cient detergent on the surface
when the high pressure water
hits the surface.
