An ordinary 1/2" garden 

hose of min. 10 m and 

max. 25 m will be suitable.

NOTE: Connection to the 

public mains  according to 


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 fi lter should be 


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 fi l-

ter is fi tted 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 


Make sure that the water 

tank is not placed on a low-

er level than the machine.

Use an external fi lter if the 

water contains impurities.

1. Make sure that the water 

hose is fi lled 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 

fi nally unbend the water 

inlet hose

2.  Turn the start/stop switch 

(1) to position"I".

the spray gun with lance 

and nozzle removed and 

let the water run, until 

the air has escaped from 

the water hose and the

5  Fields of application and 



5.1 General 

Effi cient high presure cleaning is achieved by following a 

few guidelines, combined with your own personal experi-

ence of specifi c cleaning tasks. Accessories and deter-

gents, when correctly chosen, can increase the effi ciency 

of your pressure washer. Here is some basic information 

about cleaning.

5.1.1  Detergent and  


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 da maged.

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).

5.2   Typical fi elds of application

Below you will fi nd a description of a lot of cleaning tasks which can be solved by a pres-

sure washer from Nilfi sk in association with accessories and detergents.



‘Click & Clean’

Cleaning method


Car nozzle, 

auto brush, 



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 traffi c fi lm 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 


Rims, alu-


Rim brush,

auto nozzle,


 alloy cleaning 


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. 



fl oors and 

other hard 






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.




Wood cleaner

Garden brush

Apply wood cleaner and wash before the soap dries. 

NOTE: Use the garden brush to clean off the dirt.









neutral deter-


 Patio Cleaner

Same method as for fl agstones, 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. 



 spray lance

Wash the gutter with the nozzle. Always wash towards     

downpipes. Beware not to spray under the roofi ng.


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 fl ush the dirt backwards.




sting equipment

Mount the water/sand blasting equipment and rust and 

paint is effi ciently and quickly removed. Beware not to 

damage the surface to be sandblasted.

Wash with high pressure and maybe a brush. You may 

use neutral detergent to remove moss and algae.

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.

6.2 Winding up of elec-

tric cable and high 

pressure hose 

To avoid accidents, the 

electric cable and the high 

pressure hose should al-

ways be winded carefully 


Wind up the electric cable 

and the high pressure hose 

on the appropriate hooks. 

6.1 Storing the washer

The machine should be 

stored in a frost-free

should always be emptied 

of water prior to storing as 


1. Stop the machine (turn 

the start/stop switch (1) 

to position"O") and de-

2. Restart the machine and 

activate the trigger. Let 

the machine run until no 

more water runs through 

the spray gun.

3. Stop the machine, unplug 

and wind up hose and 


4. Place spray handle, noz-

zles and other accesso-

WARNING! Always dis-

connect the electrical plug 

from the socket prior to 

maintenance or cleaning. 

To ensure a long and 

problem free working life, 

please take the following 


 Wash out water hose, 

high pressure hose, spray 

lance and accessories 

before mounting.

 Clean the connectors of 

dust and sand. 

 Make sure that no sand 

or dirt is blocking the 

movement of the pawl on 

the Click & Clean spray 

lance. Rinse according to 


 Rinse the detergent 

spraying attachment after 


 Clean the nozzles.

Any repair should always 

be made in an  authorized 

workshop with original 

spare parts.

7 Maintenance 

7.1 Cleaning of water 

inlet fi lter

Clean the water inlet fi lter 

regularly once a month or 

more frequently according 

to use. Carefully loosen the 

fi lter with a screwdriver and 

clean it. Check that it is in-

tact before re-mounting it. 

The inlet fi lter must always 

be fi tted inside the water 

inlet pipe to fi lter out sand, 

limestone and other impuri-

ties, as they will damage 

the pump valves.

CAUTION: Failure to fi t 

the fi lter will invalidate the

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 



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 


3. Flush the nozzle back-

wards with water.

7.3  Cleaning of machine  


The machine should be kept 

clean so as to let cooling air 

pass freely through the ma-

chine vents.
