Decide which end will work best for your problem
Place the end between the two pieces that you want to separate
Put weight on the opposite end of the crow bar (careful not to put your hand on the sharp edge)
You may have to readjust the crowbar several times to fully separate objects
Use the proper size and kind of crowbar for the job.
Always keep the blades away from you so you don’t accidentally hurt yourself.
Never use a makeshift bar such as a piece of pipe or an iron bar as it may slip and cause injury.
The crowbar should have a point or toe of such shape that it will grip the object to be moved, and a heel to act as a pivot or fulcrum. In some cases, a block of wood under the heel will prevent the crowbar from slipping and injuring the hand.
