Installation guidelines:
Align piston rod axis within 0.2mm perpendicularity tolerance.
Use flexible couplings for rod-end connections. Lubricate with ISO VG32 hydraulic oil
during initial setup. Avoid side loads exceeding 15N·m. For vertical mounting,
install exhaust mist lubricator (model AM400 recommended).
