 Installation guidance: 
            Use M12×1.75 mounting bolts (grade 8.8 minimum). Align cylinder axis within 0.2mm 
            perpendicular tolerance. For adjustable stroke models, perform 10-15 test cycles 
            after initial adjustment to stabilize cushioning performance. Lubricate through 
            air supply (ISO VG32 turbine oil recommended).
