least 10 metres to absorb pos-
sible pressure peaks (min diam-
eter ½ inch).
Operation by suction (for ex-
ample from a rainwater vessel)
is carried out without backflow
preventer. Recommended suc-
tion set: 126411387.
As soon as water has flown
through the BA valve, this water
is not considered to be drinking
water any more.
IMPORTANT! Only use wa-
ter without any impurities. If
there is a risk of running sands
in the inlet water (i.e. from your
own well), an additional filter
should be mounted.

5 Fields of application and working
methods
5.1 General Efficient high pressure cleaning is achieved by following a few
guidelines, combined with your own personal experience of specific
cleaning tasks. Accessories and detergents, when correctly cho-
sen, 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 be-
ing cleaned. Note: It is important that the detergents do not dry up.
Otherwise the surface 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 supplemen-
tary effect that cuts through dirt (especially by car washing).

10
5.2 Typical fields of application
Below you will find a description of a lot of cleaning tasks which can be solved by a pressure washer
from Nilfisk in association with accessories and detergents.
Task Accessories ‘Click
& Clean’
Cleaning method
Car Car nozzle,
auto brush,
undercarriage
nozzle,
Foam sprayer,
Car Combi Cleaner
1. Apply Car Combi Cleaner with the foam sprayer. Always start
from the bottom and work upwards. Let Car Combi Cleaner act
for at least 5 min.
2. Wash the car with the car nozzle, which has been optimized for
quick and gentle cleaning of enamelled surfaces (the jet is wider
and not so sharp). Start at the front of the car and work back-
wards to avoid water from penetrating by the door mouldings.
3. U se the brush for removal of traffic film which is not removed by the
nozzle. If the car is very dirty, apply Car Combi Cleaner again.
4. Attach the undercarriage nozzle and clean undercarriage and
wheel arches.
5. Remove water from the surface of the car with the scraper
on the car brush. Make sure that all grains of sand etc. have
been removed before using the scraper. Wipe with a wash
leather where the scraper cannot reach.
Rims, alu-
minium
Rim brush,
auto nozzle,
atomizer,
Alu Cleaner
Apply Alu Cleaner with an automizer. Let it act for approx. 5 min.
and wash with the rim brush. For steel rims, use Car Combi
Cleaner. Use the foam sprayer and wash with rim brush.
Be careful! The high pressure jet may damage the tyres.
Flagstones,
concrete
floors and
other hard
surfaces
Powerspeed®
nozzle,
Stone & Wood
Cleaner,
Patio Cleaner
Wash towards outlets or the like. On surfaces with moss or algae
you may start by applying Stone & Wood Cleaner with the foam
sprayer. Wash before the soap dries. Another more effective and
quicker method is to use the Patio Cleaner. Thus you will also
avoid splashes.
Garden
furniture,
wood
Wood Cleaner
Garden brush
Apply Wood Cleaner and wash before the soap dries.
NOTE: Use the garden brush to clean off the dirt.
Brickwork,
Wood work
Powerspeed®
nozzle,
Stone & Wood
Cleaner,
Patio Cleaner
Same method as for flagstones, but be careful - bad joints and
wood may be damaged by high pressure. You may choose only
to use the Tornado®nozzle. Adjust the distance (pressure) to
the quality of the joints and the wood. Patio Cleaner can also be
used on vertical surfaces.
Gutter Undercarriage
nozzle
Wash the gutter with the nozzle. Always wash towards
downpipes. Beware not to spray under the roofing.
Cleaning
of drain
pipes, out-
lets, down
pipes etc.
Tube cleaner Push the tube cleaner approx. ½ m (to mark) into a tube or drain
and activate the trigger of the spray handle. The nozzle opening
turning backwards will pull the cleaner through the tube. The
nozzle will break down the „plug“ and flush the dirt backwards.
Rust, paint Water/sandblasting
equipment
Mount the water/sand blasting equipment and rust and paint
is efficiently and quickly removed. Beware not to damage the
surface to be sandblasted.
Green-
house
Tornado®PR nozzle
brush, Stone &
Wood Cleaner
Wash with high pressure and maybe a brush. You may use Stone
& Wood Cleaner to remove moss and algae.
Garden
tools, lawn
mover
Tornado®PR
nozzle, Power-
speed®nozzle,
multiangle adaptor,
Metal Cleaner
Rinse the worst dirt off with the nozzle. Apply Metal Cleaner with
the foam sprayer and let it act for approx. 5 min. Wash with the
nozzle.You may use the multiangle adaptor for hard to get at
areas to avoid splashing.
