Operation tip:
Always loosen both adjustment nuts before changing stroke length.
Apply silicone-free lubricant (ISO VG32) monthly in high-cycle applications.
Maximum side load: 35N at full extension.
Avoid overtightening adjustment nuts beyond 2.5Nm torque.
Use alignment jigs when installing in multi-cylinder setups to prevent binding.
