4.5 Working methods
Your high pressure washer has been developed for cleaning according to the so-called „2-step method“.
STEP 1 Application of detergent
STEP 2 High pressure cleaning
In practice the working process is dictated by the actual job, but as a starting point, the following working
method can be described:
1. Apply detergent under low pressure and to a dry surface. The dilution is chosen according to the job,
and the adjustment is made on the metering unit.
2. Allow some time for the detergent to work. Let the detergent act on the dirt/surface for a short time
(but don’t let it dry) prior to pressure cleaning - usually a few minutes.
3. High pressure agitation. Clean all surfaces under high pressure.
4. Rinse with fresh water afterwards, if necessary. To make sure that soil and detergents are removed
from the surface.
Optimum cleaning results will be achieved by following these 3 simple Tips:
Tip no. 1
When using a detergent, 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.
Tip no. 2
When applying a detergent on large vertical surfaces (i.e. the sides of a truck) work from the bottom - up.
You will avoid detergent running down the surface and forming dark streaks on the surface
Tip no. 3
During the high pressure cleaning activities, work so that the high pressure water does not run over the
surface which has not been cleaned yet (Once again, from the bottom - up). This is to ensure that there is
detergent on the surface being cleaned when the high pressure water is applied.
5.0 Disposable waste
This high pressure washer consists of parts which can damage the environment if they are not properly
disposed of. They include the following:
Oil, painted/zinc-coated parts, plastics/plastic-coated parts.
Therefore, it is important to follow the laws concerning disposal of polluting and/or environmentally danger-
ous materials when replacing spare parts or disposing of high pressure washer. It is recommended that
you take these parts to waste disposal areas or recycling plants that are approved by the state for the
disposal of these types of materials.
