public mains according to
regulations.
IMPORTANT! Only use
water without any im-
purities. If there is a risk
of running
sands in the
inlet water (i.e.
from your own well), an
additional filter should be
mounted.
1.Let the water run through
the water hose before
connecting it to the ma-
chine to prevent sand
and dirt from penetrating
the machine.
Note: Check that the fil-
ter is fitted in the water
inlet pipe and that it is
not clogged up.
2.Connect the water hose
to the water supply by
means of the quick con-
nector (inlet water, max.
pressure: 10 bar, max.
temperature: 40°C).
3.Turn on the water.

4.5 Start the machine
(when connected
to open containers
(suction mode))
The washer can take in wa-
ter from a rain water tank
as an example. The hose
for the water supply must
not be too long, approx. 5
m.
Make sure that the water
tank is not placed on a low-
er level than the machine.
Use an external filter if the
water contains impurities.
1.Make sure that the water
hose is filled completely
with water before con-
necting to the machine.
Place the entire hose in a
tank or bucket. To avoid
water spillage, bend the
water inlet hose inside
the water and then con-
nect to the machine with
the quick coupling and
finally unbend the water
inlet hose
2.Turn the start/stop switch
(1) to position"I".
3.Activate the trigger of
the spray gun with lance
and nozzle removed and
let the water run, until
the air has escaped from
the water hose and the
pump.
4.Mount spray lance and
nozzle.

5 Fields of application and
working methods
5.1 General Efficient high presure cleaning is achieved by following a
few guidelines, combined with your own personal experi-
ence of specific cleaning tasks. Accessories and deter-
gents, when correctly chosen, can increase the efficiency
of your pressure washer. Here is some basic information
about cleaning.
5.1.1 Detergent and
foam Foam or detergent should be applied onto dry surfaces so that the chemical product is in direct contact with the dirt.
Detergents are applied from bottom to top, for example
on a car bodywork, in order to avoid "super clean" areas,
where the detergent collects in higher concentration and
streams downwards. Let the detergent work for several
minutes before rinsing but never let it dry on the surface
being cleaned. Note: It is important that the detergents
do not dry up. Otherwise the surfac that has to be cleaned
can be damaged.
5.1.2 Mechanical effect In order to break down tough layers of dirt, additional
mechanical effect may be required. Special wash brushes
offer this supplementary effect that cuts through dirt (es-
pecially by car washing).
