Installation Instructions

Always DISCONNECT THE ELECTRICAL POWER before servicing equipment. This prevents electrical shock or accidental movement of the systems operated by the electrical power.

Always DISCONNECT AIR SUPPLY before servicing equipment. This prevents accidental movement of systems operated by compressed air which may result in personal injury. BLEED THE AIR SYSTEM by actuating all the valves.

Before beginning any work, clear the area and position machine for easy access. Disconnect all power sources, both air and electricity inputs. Allow any stored air in the reservoir to escape by depressing the inflate pedal.
