4. Removal of internal deposits<br />
If there are internal deposits in the pipe lines, the flow resistance increases with the result that the<br />
overflow protection can switch over.<br />
According to legal regulations, only boiler cleansing compounds which have certification marks can be<br />
used to remove the deposits:<br />
RM 100 6.287-008 dissolves limestone and simple compounds consisting of limestone<br />
and detergent residues.<br />
RM 101 6.287-013 dissolves deposits which cannot be dissolved with RM 100.<br />
Procedure<br />
Caution! The gases that are given off are combustible.<br />
Do not smoke and provide good ventilation.<br />
– Fill a 20-litre container 3/4 full of water.<br />
– Add one litre of boiler-cleansing compound to the 15 litres of water.<br />
– Connect water hose direct to the pump head and hang the free end in the container.<br />
– Connect the spray lance without nozzle and insert in the container.<br />
– Switch unit switch to “Burner on”, until approx. 40 °C has been reached.<br />
– Turn off unit and let it stand for 20 minutes.<br />
– Then pump the unit until empty.<br />
Caution: When the descaling process is in action, the handgun must always remain pressed.<br />
– To conclude, we recommend the use of an alkaline solution (e.g. RM 81) to be pumped through the<br />
unit via the detergent tank to provide protection against corrosion and to neutralise the acid residue.<br />
5. Repairs<br />
The safety valve is adjusted and sealed in the factory; it may not be changed. Checking of the overflow<br />
valve and safety valve should be carried out only by a specialist technician.<br />
6. High-pressure hoses<br />
Devote special attention to the hoses. Every high-pressure hose must accord with the safety<br />
regulations and must be marked with the maximum permitted operating pressure, the manufacturer’s<br />
set date for usage and the manufacturer.<br />
High-pressure hoses may not be kinked, stretched, crushed or damaged in any other way. Damaged<br />
high-pressure hoses are in danger of bursting and must be replaced without delay.<br />
High-pressure hoses of short service life and those which are not repaired properly are extraordinarily<br />
dangerous. Therefore use only certificated and marked high-pressure hoses.<br />
Kärcher original high-pressure hoses meet the safety requirements.<br />
7. Notes on the fuel pump for the burner<br />
Even when the unit is running in cold-water mode, it must not be allowed to operated without fuel oil or<br />
diesel in the fuel tank, otherwise there is a danger that the fuel pump will dry-run and in consequence<br />
the drive clutch and fuel pump will be destroyed.<br />
