Generated by mechanical equipment failure is inevitable, due to various unknown factors. Life is precious, we must have a variety of ways from the failures will be reduced to a minimum.
    Machinery and equipment during use, as parts wear and deformation may result in some sort of imbalance between; lubricant will gradually dirty, metamorphic; some bolts loose connection that may arise and so on. The emergence and development of these conditions, will speed up the machinery and equipment damage, resulting in the failure rate increase. Technical maintenance task is the prevention of these phenomena and the emergence of a later date and remove.
    In mechanical maintenance work, because they do not strictly abide by the operation of technical requirements, such as improper operation, adjust the work did not meet the technical requirements, the use of substandard lubricant and hydraulic oil, or mechanical dirty and so on, often leading to accelerated damage to mechanical reasons. In addition, the operation of technical level of workers has a direct impact on the life of machinery.
    Technical maintenance and use of operational factors are subjective factors. To establish a reasonable maintenance regime and strict implementation of technical maintenance and use of operating procedures is to ensure that machinery and equipment is reliable and an important way to improve their life.
    Machinery and equipment maintenance and use of operation is very important, and regular maintenance to operate properly in the use does not bark to the effect that the odds of failure are much smaller.
