Jacks

When setting up a jack, make certain that the:
  • Base rests on a firm level surface
  • Jack is correctly centered
  • Jack head bears against a level surface
  • Lift force is applied evenly.

Proper maintenance of jacks is essential for safety. All jacks must be inspected before each use and lubricated regularly. If a jack is subjected to an abnormal load or shock, it should be thoroughly examined to make sure it has not been damaged.

Hydraulic jacks exposed to freezing temperatures must be filled with an adequate antifreeze liquid.
