  • Page 83 Detailed description of the inspection and maintenance work Wipe off using a soft cloth (and some water with a normal household detergent). Leaking connections can be identified by moisture or crystals at the threaded connections of the hoses, at the sealing lips of the piston inside the dosing cylinder or at the valve. If any liquid becomes visible below the first sealing lip, it has to be checked at short timely intervals whether any liquid will build up under the second sealing lip, too.
