DIM123EN - 26.04.2022
Carrying out the maintenance activities described below requires
special knowledge. For this reason, these maintenance activities
must be carried out only by authorized personnel of the
manufacturer!
The activities described here are only permitted to be carried out
after training or instruction by the manufacturer of the pressure
accumulator.
According to the pressure equipment directive 2014/68/E4, the
pressure accumulators built into the machine are of category I/
module A. They are provided with a CE mark by the manufacturer,
and a declaration of conformity has been issued. Due to this
categorization, the pressure accumulators must be subjected to an
external and internal inspection and a strength test by a qualified
person after a period of time recommended by the pressure
accumulator's manufacturer. For pressure units with gas cushions, an
internal inspection is recommended after 10 years at the latest. We
recommend to replace the pressure accumulator after 5 years to
avoid an internal inspection that is laborious and expensive for this
size of pressure accumulator.
The machine operator is obliged to check the pressure accumulator
according to applicable rules and directives. Defective pressure
accumulators must be disposed of according to applicable rules after
they have been depressurized by a qualified technician. The
directives and regulations applicable in the country of use must be
followed.
The pressure accumulator must be replaced as specified in the user
manual of the manufacturer.
Screws on the hydraulic system, the connected components, and the
supply lines must be tightened to the manufacturer's specified
torques.
