inspection, the skill in machine operation, the working conditions, the quality of used
lubricating oil, the frequency of oil replacement, the quality of land to be dug, the digging
rate, the schedule for maintenance and repairs should be decided considering the state
of engine, the indication of the hour meter, the degree of wear in each part, the state of
hydraulic system, your experience and data.
