Tractor before the input, in the provision of lubrication, speed, load conditions for a period of time, at the same time to carry out the necessary inspection, adjustment and maintenance, so that the normal state of technology, this series of work known as the run in. After the new purchase or overhaul of the tractor must be run in order to put into use, otherwise it will shorten the service life of the tractor.

A, the engine idle running

　　　According to the instructions of the order after the engine is started, engine by low-speed, medium speed, high speed, namely small throttle, oil and throttle the order, in order to run every 5 minutes.

　　　In the engine idle running in process, should carefully check the working condition of the engine, an air compressor, a hydraulic oil pump, to observe the abnormal phenomenon and sound, check whether there is water leakage, oil leakage and leakage phenomenon, the instrument is working properly. When found abnormal phenomenon, should immediately stop, after the failure to re run in.

Two, power output shaft no-load running

　　　The engine throttle control handle is arranged in the oil gate position, engine to despatch, respectively make the power output shaft with low speed and high speed each running 5 minutes, check whether the abnormal phenomenon. After running to the power output shaft in the neutral position.

Three, the hydraulic system running in

　　　Start the engine will throttle in the throttle position operation, control the distributor handle, lifting suspension mechanism several times, observe the abnormal phenomenon. Then in the suspension structure hanging quality about 500-800KG heavy or equivalent quality tools, so that the engine running at high throttle position, to operate the distributor handle, the suspension mechanism can travel all rise and fall, the number of not less than 20 times. Check the hydraulic suspension mechanism can be fixed at the highest position or the required position, lift time and there is no leakage phenomenon.

　　　In the tractor at rest, the engine with low, medium and high speed operation, and smoothly to the left and right steering wheel 10 times, observe the tractor before running around with the situation, the sound is normal, steering wheel is light, smooth. In the process of running in the process if the fault, should be timely analysis of the reasons and rule out.

Four, tractor air drive and load running

When the engine idle running, the power output shaft and the hydraulic system after running in to confirm the tractors' technical condition is completely normal, can carry on the machine running, running in order and time according to the provisions in the specification. Total running 60 hours. When running in the low speed, the turning operation and the appropriate use of a single side brake, and the test of emergency braking at high speed. Kongshi running. When the tractor technical state completely normal can to run a load and load when running a load must be must be steeled file bits from low to high by documents.
