10.3 Maintenance schedule
Valves require low maintenance if used as intended.
For a long and reliable operation of the valve, Bosch Rexroth recommends regularly
checking the hydraulic system and the valve.
10.3.1 Checking for leakage
Check the valve for leakage. An early detection of hydraulic fluid loss may help you to
identify and remedy errors. Bosch Rexroth therefore recommends that you keep the
valve and/or the system permanently clean.
10.3.2 Checking for noise development
Check the valve for noise development. Based on noise development or the increase
in noise development, a possible failure of one or several components can be
recognized in time and consequential damage can be avoided.
10.3.3 Checking the mounting elements
Check that the mounting elements are attached firmly. All mounting elements are to
be checked with the system being switched off, depressurized and cooled down.
10.4 Repair
WARNING
Explosion hazard due to improper repair!
Improper repair will void the explosion protection!
▶ For repair works, the valve may only be disassembled to the extent described in
these operating instructions.
▶ Defective parts may only be replaced by new, interchangeable components in
original equipment quality.
10.5 Rectifying external leakage
External leakage at the valve connection surface can be rectified on site.
Other leakages have to be rectified by specialists of the manufacturer.
