Danger

Risk of burns due to hot oil or hot parts of 
the plant. Allow pump to cool down for 15 
minutes before oil change.

Note

Please dispose off used oil only in the col-
lection points provided for them. Please 
hand over old oil, if any, only at such plac-
es.  Polluting the environment with used oil 
is a punishable offence.

1 Oil container lid
2 Oil drain screw



Keep a collection basin for old oil ready.



Remove the lid of the oil container.



Unscrew the oil drain screw and collect 
used oil. 



HDS-C 7/11, HDS-C 9/15: Replace O 
Ring 11x2 (order no: 6.362-458.0) and 
turn in the oild drain screw.
HDS-C 8/15-E: Replace copper washer 
14x18 (order no. 7.362-005.0) and turn 
in the oil drain screw. 



Slowly fill in new oil until the "MAX" 
marking on the oil container. 



Close the oil container with the lid.



Deliver the old oil to the respective col-
lection centres.



Loosen covering nut and take off hose.



Take out sieve.

Note

If necessary turn in screw M8 appr. 5 mm 
inwards and therewith pull out sieve.



Clean sieve in water.



Push sieve inwards.



Put on hose.



Tighten covering nut firmly.

There will be calcium deposits in the plant if 
the softening plant (optional) is accidentally 
out of operation for a long time. Calcium de-
posits in the plant can lead to following dis-
ruptions:

–

higher pipe resistances, 

–

reduced heat transfer at the heat ex-
changers, 

–

failure of components spoilt on account 
of calcium deposits.

In the interest of environmental safety, use 
only tested and approved decalcifying 
agents (calcium dissolution acids with test 
marking) to decalcify. The high pressure 
unit should be decalcified using the Kärch-
er calcium solvent.



Danger

Only persons trained by Kärcher are au-
thorised to decalcify the plant. Risk of ex-
plosion due to combustible gases! Do not 
smoke during decalcification; ensure prop-
er ventilation. Risk of burns injury on ac-
count of acid. Wear protective glasses and 
protective gloves.



Unscrew the hand-spray gund and in-
sert the hose in the drainage duct so 
that the water can flow freely.



Set the hot water temperature to 40 °C.



Shut off water supply.



Start the washing programme with hot 
water until the swimmer container for 
fresh water is almost empty.



Add 0.5 litre calcium solvent to the 
swimmer tank for fresh water.



Leave the water inlet open until the 
swimmer tank for fresh water is full 
again.



Switch on the plant briefly and then let 
the calcium solvent react. Repeat this 
process every 4 to 5 minutes until the 
swimmer tank for fresh water is almost 
empty.



Open the water inlet and let the wash-
ing programme with hot water run for 5 
minutes until the tank is rinsed.



Connect the hand-spray 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). 



Dispose off fuel residues according to 
environment safety laws. 

The correct setting of the ignition elec-
trodes is very important for the burner to 
function properly. The settings have been 
indicated in the above drawing.
