Abstract
An initial weight of a grease storing cartridge attached to a pump is measured, and the measured value is compared with a reference weight and it is determined whether the initial weight of the cartridge is within an appropriate range or not. The weight of the cartridge is measured before and after execution of one operation cycle of the pump, and it is determined whether the difference therebetween (i.e., weight of grease which is actually supplied during one operation cycle) is within an appropriate range or not.
