Installation guidelines:
Lubricate with ISO VG32 turbine oil before operation.
For vertical mounting, use rod-down orientation to prevent seal wear.
Adjust stroke under depressurized condition using 6mm hex key.
Avoid side load exceeding 30N. When used in tandem applications,
synchronize cylinders using flow control valves to prevent drift.
