Operation guidance:
Adjust stroke while pressurized using 3mm hex key. Lubricate adjustment screw monthly with ISO VG32 hydraulic oil. Avoid side-load forces exceeding 15N during operation.
Critical note:
Always degrease stainless steel rod before installation. Maintain 0.3-0.8 MPa air pressure for optimal cushioning performance. Max lateral load capacity: 30N at full extension.
