Operation notes:
Requires filtered lubricated air (ISO 8573-1:2010 class 4.4.3).
For vertical mounting, use anti-vibration pads (AVP-40 accessory recommended).
Lubricate guide shafts every 500,000 cycles using ISO VG32 hydraulic oil.
Critical parameters:
Maximum permissible radial load - 250N at cylinder base.
Do not exceed 120% of rated torque during emergency stop conditions.
Allow 2-second dwell time between rotation and clamping actions.
