------ WARNING! ------

When you are using hydraulic cylinders and puller studs, always ensure that the rated capacity of the puller stud meets or exceeds the rated capacity of the hydraulic cylinder. If the puller stud does not meet or exceed the rated capacity of the hydraulic cylinder, a sudden failure of the puller stud could occur. The sudden failure of the puller stud could result in personal injury or death.

----------------------


NOTICE

Do not use threaded rods that have not been hardened as tooling with hydraulic cylinders. The maximum rated tonnage should be stamped on one end of the puller studs. Do not use threaded rods that have not been stamped with the rated tonnage.
