Maintenance note:
Lubricate piston rod weekly with ISO VG32 hydraulic oil. Avoid side loads exceeding 50N.
For vertical mounting, install speed controller on lower port to prevent piston slam.
Critical parameters:
Max piston speed 0.5 m/s (cushioned) / 1.0 m/s (uncushioned).
Minimum operating pressure 0.15 MPa for stable magnetic sensor operation.
