10.4 Maintenance
▶
Perform maintenance at the intervals specified in the maintenance schedule of
the machine/system manufacturer.
Seals of attached and installed hydraulic components are subject to a natural
process of wear and aging. Bosch Rexroth recommends replacement at
appropriate time intervals. The intervals are mainly determined by the operating
conditions and the cleanliness of the hydraulic fluid.
▶
As a precaution, exchange seals at reasonable time intervals.
Preventive maintenance (e.g. hydraulic fluid care) as well as compliance with the
pressure and temperature specifications extend the life cycle of the system
and/or the accumulator shut-off block.
