An apparatus for lifting a pneumatic hammer from the hammer's work surface. A pneumatic lift attachment is provided having a support housing. Attached to the support housing is a lift plate, containing a guide hole and an adjustable chain, for securing a pneumatic hammer to the lift plate. Defined within the housing is an air cylinder containing a piston having a piston rod. The piston is responsive to air supplied to the air cylinder, which drives the piston and piston rod downward. Attached to the bottom of the piston rod is a foot. As the foot meets the ground's surface, the support housing is lifted, freeing the attached hammer from the work surface.
