9.3 Cleaning the lance

The lance, both brushes and the adapter of the quick coupling each have a
sealing ring (Fig. 55). If the sealing ring is obviously damaged, then it has
to be replaced.
Four sealing rings are delivered for this purpose.
Proceed as follows to replace the sealing rings:
1. If you have not done so already, release the attachment from the pistol
or the adapter from the high-pressure cleaner.
2. Split the worn sealing ring with a sharp knife being careful not to
damage the surrounding plastic.
3. Pull over the new sealing ring. It should slide into the groove completely.
Use the cleaning needle supplied to free the lance of deposits.
WARNING: Danger of injury! The cleaning needle is sharp! Work
carefully with it and make particularly sure that it does not fall into
the hands of children.
1. If you have not done so already, release the lance from the pistol.
2. Push the cleaning needle into the lance (Fig. 56) and unblock the
channel of calcium carbonate deposits and dirt.
NOTE: If you lose the cleaning needle, you can use a straightened paper
clip instead.
