Installation tip:
When using the adjustable stroke feature, always lock the position indicator plate with 4-5Nm torque
and verify stroke limits with limit switches. Maintain 0.5mm minimum parallel alignment tolerance between
cylinder axis and load movement direction.
Requires 40μm filtered air with ISO VG32 lubricator oil (drip feed at 1/3 drops per minute).
Do not exceed 0.5m/s piston speed in vertical downward installations.
