Operating instructions
2. Manual controls
For your own safety and the safety of others, the high-
pressure module must be switched off before service and
maintenance works are carried out.
However, not all the parts of the system to be serviced
are easily accessible. This makes it necessary to move
certain parts during the service and maintenance works.
For this reason the operating mode „manual control" is
provided. The manual control is selected using the manu-
al unit in the central controls of the downstream high-
pressure cleaning equipment. Please refer to the „Mainte-
nance" section in the operating instruction for this high-
pressure cleaning equipment about selecting this type of
operation.
