- Textile machinery with space constraints
Operation tip:
Always lubricate with ISO VG32 hydraulic oil before initial use.
For micro-adjustments, loosen lock nut and rotate stopper clockwise
(1 full rotation = 1.5mm stroke reduction). Maintain 0.3–0.5mm
clearance between stoppers at minimum stroke.
