Installation notes:
Use locknuts (not included) on adjustment screws after positioning.
Lubricate with ISO VG32 hydraulic oil before initial operation.
Avoid side load exceeding 15% of maximum thrust capacity.
- Loosen both locking nuts on the stroke adjustment screws
- Rotate screw clockwise to decrease stroke (max 3 full turns)
- Set desired position using scale markings (0.5mm increments)
- Securely tighten locking nuts (25-30N·m torque)
- Perform test cycle at reduced pressure before full operation
