Maintenance restoring crawler drilling rig performance and prolong the life of one of the most effective means. However, in actual operation, use and maintenance staff, there are many wrong practices, thus affecting the normal use of its, in particular that:

Oil in the diesel engine use is essential, mainly for lubrication, cooling, cleaning and so on. Therefore, many drivers pay attention to check the oil for fuel, and according to the standard add, but neglected the quality of lubricating oil check and to have deterioration of oil change, resulting in some of the moving parts of the engine is always running in the poor lubrication conditions, thus speeding up the mechanical wear. Oil loss under normal circumstances is not great, but it is easily contaminated, thus losing the protection of diesel engines. In the course of operation of the engine, lots of dirt (generated by the incomplete combustion of fuel such as soot and carbon deposition and fouling) are entered in the oil.

Through the above described, we can see that error the crawler drilling rig maintenance will only be counterproductive, so we must avoid in the Nissan.
