When jacking up vehicles, make certain no one is
under the vehicle to be raised. Set the hand brake
firmly and block the front wheels if a rear wheel is
being changed. Block the rear wheels if a front
wheel is being changed. Place blocking or other
supports under the vehicle when it is raised to the
desired height to prevent it from dropping if the jack
fails.
Make certain that hydraulic jacks are filled with oil
and that there are no visible oil leaks before using.
Any new or repaired jack should be carefully
inspected by the operator prior to use.
Overloading can be hazardous to the jack, the
operating personnel, and the load in event of jack
failure.
Be aware of the capabilities of the jack, especially
its load capacity.
