Detailed Safety Instructions

Warning

1.Be sure to use our Vacuum Pad Bellows Type as the pad rubber to attach the Mark-free Resin Attachment. If the shape of the Resin Attachment and pad rubber is not appropriate, Resin Attachment may come loose or leak a large amount.

Caution

1.For the bellows type pads, use the allowable pressing stroke in the dimension table as a guide, do not crush the bellows too much. Excessive crushing may cause premature wear of the bellows, cracking of the lip, and deformation due to strain, which may result in suction failure.

2.When selecting a product, pay attention to the following points and perform the suction test on the actual application. (1) Due to the characteristics of the material, the bellows may stick to each other and deform depending on the usage conditions. (2) Since the lip of the Mark-free Resin Attachment is made of hard resin, it reduces suction marks compared to rubber vacuum pads, but it does not completely prevent suction marks. The degree of reduction of suction marks varies depending on the environment and the workpiece. (3) Compared to rubber vacuum pads, the Mark-free Resin Attachment has a significant effect on suction performance due to leakage from the suction surface. Ensure that the flow rate of the vacuum source is as large as possible. Also, it cannot be used to hold a vacuum.

3.Be sure to clean the suction surface of the vacuum pad before use. Deposits may remain as suction marks. When cleaning, be careful not to scratch the suction surface, and do not use organic solvents.

4.Select a pad rubber material suitable for the operating conditions to install the Mark-free Resin Attachment.
