Installation tip:
For optimal performance, maintain 0.5-1mm alignment tolerance during mounting.
Lubricate with ISO VG32 hydraulic oil before initial use. Adjust cushion screws
clockwise to increase damping force (max 1.5 turns from fully closed position).
Note:
Requires filtered air (5-40μm) with lubrication. Avoid side load exceeding 30N.
For vertical mounting, use rod-down orientation to prevent seal wear.
