The planning process and the implementation of preventive maintenance work does not represent only a brief way to reduce maintenance costs, but also represents an investment of capital and partial profit in the long term. But it found that the implementation of an effective preventive maintenance program we will get from the reality of the data and practical experience on the following features: Low maintenance cost / unit of production rate. Low-stop hours of productive machinery. Lower the cost of repair rate for capital investment. Consequently, we find that the timing of the implementation of preventive maintenance compared to maintenance treatment has shifted from when maintenance must be done to when you want to do maintenance work.
