* Ensure that sufficient mounting strength is secured for this product. (As a
guideline, it should be 2 to 3 times the maximum drag listed in the catalogue.)
* Do not use this product in a vacuum or a location where it may come in contact with oil.
* Ensure that an eccentric load is not applied to the soft absorber
