The operator must carry out regular visual
examination of the distribution valve
dependent on the operating conditions and
the potential danger in order to prevent
leakage and damage. The distribution
valve also has to be disassembled in
corresponding intervals and checked for wear
(see chapter 12 "Assembly / disassembly of
spare parts").
