PRODUCT DESCRIPTION

Hein-Werner Air Actuated Hydraulic Truck Jacks are designed to lift, but not support, rated capacity loads. They are 

designed to be used vertically. Immediately after lifting, loads must be supported by appropriate mechanical means 

(as opposed to hydraulic means), such as a pair of appropriately rated jack stands.

           

NEVER

 use hydraulic jack as stand-alone device. After lifting, 

immediately

 support the lifted vehicle 

           with a pair of appropriately rated vehicle stands.
