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.

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.

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).

11
5.2 Typical fields of application
Below you will find a description of a lot of cleaning tasks which can be solved by a pres-
sure washer from Nilfisk in association with accessories and detergents.
Task Accessories
‘Click & Clean’ Cleaning method
Car Car nozzle,
auto brush,
underchassis
nozzle,
Foam sprayer,
neutral car wash
1.Apply neutral car wash with the foam sprayer. Always
start from the bottom and work upwards. Let neutral
car wash act for at least 5 min.
2. Wash the car with the car nozzle, which has been opti-
mized for quick and gentle cleaning of enamelled sur-
faces (the jet is wider and not so sharp). Start at the
front of the car and work backwards to avoid water from
penetrating by the door mouldings.
3. Use the brush for removal of traffic film which is not remo-
ved by the nozzle. If the car is very dirty, apply neutral
car wash again.
4.Attach the undercarriage nozzle and clean undercar-
riage 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 scra-
per. Wipe with a wash leather where the scraper cannot
reach.
Rims, alu-
minium Rim brush, auto nozzle,
atomizer,
alloy cleaning
agent
Apply alloy cleaning agent with an automizer. Let it act
for approx. 5 min. and wash with the rim brush. For
steel rims, use neutral car wash. Use the foam sprayer
and wash with rim brush. Be careful! The high pres-
sure jet may damage the tyres.
Flagstones,
concrete
floors and
other hard
surfaces
Powerspeed®
nozzle,
neutral detergent
Patio Cleaner
Wash towards outlets or the like. On surfaces with moss
or algae you may start by applying neutral detergent
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.
Brick-
work,
Wood
work
Powerspeed®
nozzle,
neutral deter-
gent,
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 Underchassis
spray lance 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/sandbla- sting 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,
neutral detergent
Wash with high pressure and maybe a brush. You may
use neutral detergent to remove moss and algae.
Garden
tools,
lawn
mover
Tornado®PR noz-
zle, Powerspeed®
nozzle, multian-
gle adaptor, de-
greaser
Rinse the worst dirt off with the nozzle. Apply degreaser
with the foam sprayer and let it act for approx. 5 min.
Wash with the nozzle. You may use the multiangle adap-
tor for hard to get at areas to avoid splashing.

limestone and other impuri-
ties, as they will damage
the pump valves.
CAUTION: Failure to fit
the filter will invalidate the
guarantee.

15
7.2 Cleaning of nozzle A clogging up in the noz-
zle causes a pump pressure
which is too high. This is
why cleaning is required
immediately.
1.Stop the machine and
disconnect the nozzle.
2.Clean the nozzle. IM-
PORTANT: The cleaning
tool (11) should only be
used when the nozzle is
detached!
3.Flush the nozzle back-
wards with water.
7.3 Cleaning of machine
vents The machine should be kept clean so as to let cooling air
pass freely through the ma-
chine vents.
7.4 Greasing of coup-
lings
