Installation guidelines:
Lubricate with ISO VG32 hydraulic oil before initial use.
For adjustable stopper setting: Loosen lock nut, position stopper, then torque to 3.5N·m.
Avoid side load exceeding 30N. Recommended re-lubrication interval: 3 months under normal operation.
Critical notice:
Do not exceed 150% of rated pressure during adjustment.
Use clean dry air with 5-40μm filtration.
Buffer adjustment requires depressurization - follow LOTO safety procedures.
