- Page 5 Operator ♦This operation manual is intended for those who have knowledge of machinery using pneumatic equipment, and have sufficient knowledge of assembly, operation and maintenance of such equipment. Only those persons are allowed to perform assembly, operation and maintenance. ♦Read and understand this operation manual carefully before assembling, operating or providing maintenance to the product.
- Page 6 Caution ■Do not touch terminals and printed circuit board inside the product. Otherwise it can cause electric shock, malfunction or damage to the product can result. After maintenance is complete, perform appropriate functional inspections. ■ Stop operation if the equipment does not function properly. Safety cannot be assured in the case of unexpected malfunction.
- Page 7 ∗Wiring •Do not pull the lead wires. Especially never lift actuator equipped with Auto switch by holding the lead wires. It can result in damage to inside of Auto switch causing malfunction. •Do not bend or apply tensile stress to lead wires repeatedly. Wiring with repetitive bending stress or tensile stress can cause peel of a sheath.
- Page 8 ∗Adjustment and Operation •Adjust an Auto switch in the middle of operating area and then fix it. Adjust the position of Auto switch in a way that a piston stops at about the middle of operating area (where switch is in ON status).
