ABSTRACT:
A jack is adapted for both lifting and pumping functions driven by a common drive motor. This jack has a detachable motor/air pump unit for use apart from the remainder of the jack. The motor/air pump unit is formed as a single unit which, if desired, is independently supported by a stand which is integral therewith. The unit is operatively, removably received in a saddle of the jack, where it is secured in place by a pivoted strap and buckle arrangement.
