Installation tips:
Lubricate with ISO VG32 hydraulic oil before initial use.
Avoid side load exceeding 15N·m. For vertical mounting,
use the anti-rotation key slot (3mm width) to prevent
unintended stroke adjustment.
- Loosen the lock nut (17mm wrench size)
- Rotate adjustment screw: CW to shorten stroke, CCW to extend
- Each full rotation ≈ 1.5mm stroke change
- Re-tighten nut to 5-7N·m torque
