Page 6 Caution 1. If pressure is applied to the external magnet gripper parts, there is a possibility that air will get inside the cylinder from the rod seal section. ( Example : inside a chamber, etc.) 2. Keep away from objects which are influenced by magnets. As the body magnets are built-in, do not allow close contact with magnetic disks, magnetic cards, or magnetic tapes.

Preparation before piping Before piping is connected, it should be thoroughly blown out with air (flushing) or washed to remove chips, cutting oil, and other debris from inside the pipe. 2. Winding of sealant tape When screwing piping or fittings into ports, ensure that chips from the pipe threads or sealing material do not enter the piping.

Page 15 When using solid state auto switches, ensure the application is set up so the signals for the first 50 ms are invalid. Depending on the operating environment, the product may not operate properly. 2-8.Other 1)Refer to the Fittings and Tubing Precautions (Web catalog) for handling One-touch fittings. 2) Ensure the mounting bracket or peripheral parts are not protruded from the magnetic attraction surface.
Page 16 Caution 3) When multiple magnet grippers are used side by side, mount them so that the attraction surfaces are not uneven. Otherwise, adequate holding force is not available, and the workpiece may slip or fall. 3.How to use 3-1.Holding force Adjustment ①Secure the stopper with a ➁With the workpiece ③Secure the stopper with a...
