If the softening equipment (optional) does 
not operate for a longer period of time, then 
there will be lime scale in the equipment. 
The following interruptions can occure by 
lime scales:

–

larger pipe line resistance,

–

lesser heat transvertion at the heat ex-
changer,

–

Interruption by lime scaled parts.

In oder to decalcify, and to protect the envi-
ronment, only approved agents are to be 
used (agents with mark of conformity). High 
pressure equipment shall be decalified with 
the agent provided by Kärcher.



Danger!

Only individuals , who were instructed by 
Kärcher, are allowed to decalcify the equip-
ment. Danger of explosion because of 
flamable gases! Do not smoke during the 
decalcifation, make sure there is enough 
fresh air. Danger of chemical burn because 
of acid. Wear secutity glasses and gloves.



Disconnect the hand blowing gun and 
place the hose at the used water shaft, 
so that the water can flow freely.



Put the hot water temperature at 40 °C .



Close the water input.



Start the washing program with hot wa-
ter, until the floating container of the 
fresh water is almost empty.



Put 0,5 liter of decalcifying agent into 
the floating container of the fresh water. 



Open the water input until the floating 
container of the fresh water is filled.



Start up the equipment and let the 
agent take effevt. Repeat this proce-
dure every 4...5 minutes, until the float-
ing container of the fresh water is 
almost empty.



Open the water input, and to rise, let the 
washing program run for 5 minutes us-
ing hot water.



Connect the blowing gun to the high 
pressure hose.

Caution

Danger of damage to the fuel pump. Do not 
interchange the forward and backward flow 
pipes for fuel.  This can cause the fuel 
pump to dry run and get damaged. 



Pull out the fuel hoses on the fuel pump. 



Remove the fuel tank from the plant. 



Rinse the fuel tank thoroughly (allow 
the fuel tank rinsed with water to dry 
properly). 



emergency off main switch is put to „0“) the 
clock in the control head of the base ex-
changer will stop and must be readjusted.



Danger!

danger of injury because of possible dam-
aged parts of the high pressure jet, danger 
of burns because of hot equipment parts.. 
When working, while the equipment is open 
take special care, and obey all safty notic-
es!.

The following parts are possible to be hot-
ter than 50 °C:

–

exhaust pipe and exhaust opening
