Abstract
A grease gun comprising a body having first and second chambers, first and second pistons within those first and second chambers, primary and secondary grease channels, a grease outlet and an actuator, is provided. Actuation of the actuator by a user causes first and second pistons to move within first and second chambers. The body may further comprise a pressure sensitive spool which allows the grease gun to move from a high flow/low pressure operation to a high pressure/low flow operation when there is a grease blockage that causes an increase in the pressure in the body.
