Operation Tip:
For optimal performance, maintain air quality at ISO 8573-1:2010 Class 3-4-3 standards.
Lubricate with ISO VG32 turbine oil if used without built-in lubricator. Avoid lateral
loads exceeding 15N to prevent rod bending.
- Loosen the lock nut with 8mm wrench
- Rotate stopper screw (2.5mm hex key required)
- Verify stroke with calibration gauge
- Re-tighten nut to 0.7–1.0Nm torque
