While helping a pharmaceutical manufacturer address deficiencies in its lubrication program, I realized one area that needed attention was the variety of grease guns in the hands of the lubrication technicians. Various styles were in use, and there was a wide range of delivery volumes. The first step was to gather this motley collection of tools and choose a new standard grease gun for the company. We settled on a quality gun with a clear tube to allow users to view the type of grease that had been loaded into the gun. We calibrated the gun by measuring the delivery rate per pump.
