6. Installation and Operation Notes
-
Maintain hydraulic oil cleanliness at NAS 7 level or higher, and install a high-precision filter (≥10 μm) in the suction line.
-
Ensure proper priming before initial operation to prevent dry running damage to the pump.
-
Start the pump under no-load condition for at least 10 minutes, then gradually increase pressure to rated value.
-
Maintain proper oil temperature between 20°C and 60°C for optimal performance and service life.
-
Regularly inspect and replace hydraulic oil according to the operating environment and frequency (recommended every 2000-3000 hours).
-
Follow the specified torque values when assembling and disassembling to avoid damage to components.
-
Use only genuine YUKEN replacement parts to ensure pump performance and reliability.
