ABSTRACT:
A grease gun used to provide grease to a fitting. A first and second piston are reciprocated with respective passageways by an electric motor and act to press grease through the passageways into the fitting. The electric motor rotates a cam and the cam, in turn, moves a drive pin which is connected to the pistons through a piston block to provide the reciprocal motion. Single handed operation of the grease gun is possible after connecting it to the fitting.
