2.Water
1)Radiator should be filled with clean soft water so as to eliminate scale in the engine
cooling
system which will reduce cooling efficiency. Only after being softened can hard water such as
well water, spring water, etc. be used. Method for softening hard water is as the follows:
A. Boil hard water, then deposit for some time and filter.
B. Put 1.5g of caustic soda into one lit of hard water. When operating the tractor in cold
weather, add cooling water with freeze-proof liquid.
3. Running-in of unused tractor
The unused or overhauled tractor can not be put into operation unless it has undergone
running-in. Otherwise its performance will be affected and service life will be shortened.
1)Preparations before running-in
A.Clean the outside of the engine.
B.Inspect outside bolts and nuts, and tighten them if necessary.
C.Check the lubricating oil level, and refill to stipulated level if insufficient.
D.Inject grease into lubricating points.
E.Fill with fuel and cooling water
F.Check toe-in (4-10mm) and tire inflation pressure, readjust or reinflate if necessary.
G.Inspect the connections of battery and wires of electrical system.
2)Idle running-in of the engine
After the engine is started in accordance with specified steps, listen carefully and make
sure whether there is abnormal sound, check for leakage of water, air, oil and the readings of
the gauges. When it is made sure that the engine is in normal working condition, the next step
of running-in can be proceeded.
The unloaded running-in lasts 15 minutes, the first 7 minutes with minimum throttle, then
medium throttle for other 5 minutes and then lasts 3 minutes with full throttle.
3)Unloaded and loaded running-in of the tractor
The running-in of the tractor should be done at rated engine speed. The order and time of
running-in should be done according to the standard in Table 2-2.
