5 Working 


5.1 General 

Effi cient high pressure cleaning is achieved by following a few 
guidelines, combined with your own personal experience of specifi c 
cleaning tasks. Accessories and detergents, when correctly cho-
sen, can increase the effi ciency of your pressure washer. Here is 
some basic information about cleaning.


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. 


It is important that the detergents do not dry up. 

Otherwise the surface that has to be cleaned can be da maged.


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).

High pressure

Low pressure

The machine can take in water 
from a rainwater tank or bucket 
as examples. 

In the suction 

mode, the inlet hose must be 
fi lled with water before start-
ing up the machine

. The water 

inlet hose must not be too long, 
approx. 5 m.

1. Make sure that the water 

source is not placed on a 
lower level than the ma chine.

2. Attach the water inlet hose 

to the ma chine and place the 
other end of it in the water 

3. Start the machine.
4. Detach the spray lance 

and activate the trigger of 

the spray lance. Keep the 
trig ger activated until water 
has come out for approx. 15 
 sec onds.

5. Remount the spray lance and 

the ma chine is ready for ope-


 The in-

ternal fi lter of 
the machine is 

not intended for the fi ltration of 
large quan ti ties of impurities. If 
the water contains leaves, sand 
or the like, an external suction 
fi lter should be mount ed. For 
further in for ma tion, please 
contact your near est Gerni 
 dis trib u tor.

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 pressure washer 
from Gerni in association with accessories and detergents.


Accessories ‘Click 

& Clean’ 

Cleaning method

Car Car 


auto brush, 


Foam sprayer, 

Car Combi Washer

1.  Apply Car Combi Washer with the foam sprayer. Always start 

from the bottom and work upwards. Let Car Combi  Washer 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 traffi c fi lm which is not removed by the 

nozzle. If the car is very dirty, apply Car Combi Washer 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-


Rim brush,
auto nozzle,
 Alu  Washer

Apply Alu Washer with an automizer. Let it act for approx. 5 min. 

and wash with the rim brush. For steel rims, use Car Combi Wa-
sher. Use the foam sprayer and wash with rim brush.


Be careful! 

 The high pressure jet may damage the tyres. 


fl oors and 
other hard 




Stone & Wood
 Patio  Washer

Wash towards outlets or the like. On surfaces with moss or algae 

you may start by applying Stone & Wood Washer with the foam 
sprayer. Wash before the soap dries. Another more effective and 
quicker method is to use the Patio Washer. Thus you will also 
avoid splashes.



Wood Washer
Garden brush

Apply Wood Washer and wash before the soap dries. 


Use the garden brush to clean off the dirt.

Wood work




Stone & Wood
 Patio  Washer

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 Washer can also be used 
on vertical surfaces. 





Wash the gutter with the nozzle. Always wash towards     



 not to spray under the roofi ng.


of drain 
pipes, out-
lets, down 
pipes etc.

Tube washer

Push the tube washer 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 washer through the tube. The 
 nozzle will break down the „plug“ and fl ush the dirt backwards.

Rust, paint



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.





 PR nozzle,

brush, Stone & 

Wood Washer

Wash with high pressure and maybe a brush. You may use Stone 

& Wood Washer to remove moss and algae.

 nozzle, Power-



multiangle adaptor, 
Metal Washer

Rinse the worst dirt off with the nozzle. Apply Metal Washer 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.

made in an  authorized work-
shop 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 intact before re-mount-
ing it. 

The inlet fi lter must always be 
fi tted inside the water inlet pipe 
to fi lter out sand, limestone and 
other impurities, as they will 
damage the pump valves.


Failure to fi t the fi lter 

will invalidate the guarantee.

7.2  Cleaning of nozzle 

A clogging up in the nozzle 
causes a pump pressure which 
is too high. This is why cleaning 
is required immediately.
1. Stop the machine and dis-

connect the  nozzle. 

2. Clean the nozzle.



The cleaning tool (11) 

should only be used when 
the nozzle is detached!

3. Flush the nozzle backwards 

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.

7.4 Greasing of couplings

To ensure an easy connec-
tion and that o-rings do not dry 
up, the couplings should be 
greased regularly.
