Maintenance tasks on equipment that has been connected up should only be carried out
by qualified personnel. When using hazardous substances the appropriate safety
instructions are to be observed. Operators must be equipped with their own personal
safety equipment (protective goggles, gloves, apron).

Functioning of solenoid valves
Check and, if necessary, clean nozzles and filters
Functionality check of suction circuit (mesh filter and valve at lower input port,
protective cover)
Suction and pressure valves on the pump
