Operation tip:
For optimal cushioning performance, adjust the buffer screws in 1/4-turn increments during commissioning.
Lubricate through air port with ISO VG32 turbine oil every 500km of cumulative stroke.
Critical note:
Avoid side load exceeding 5N·m. When used in vertical orientation,
always install an air pressure holding valve for fail-safe operation.
