Frequently Asked Questions About Micro-cultivators

1. The air cooler cools with water. Some operators see that the temperature of the air cooler is high, and they are worried about damaging the machine, so they use watering to help cool down. In fact, it is a very wrong practice, the water is suddenly cooled down, the cylinder liner suddenly shrinks, it is easy to pull the cylinder, break the ring, and even the cylinder liner is broken.

2, do not pay attention to class maintenance. Some machine operators think that a few days to engage in maintenance on the line, in fact, wear and tear is a cumulative process, shift maintenance is the same main.

3, do not pay attention to the quality of fuel and lubricating oil. The poor fuel quality not only makes the machine less powerful, but also accelerates the wear of the oil pump and the core sleeve; The quality of lubricating oil directly affects the starting performance and service life of the machine, and it must not be sloppy. Lu Qibing of Shahe Village, Yaowan Township, Yichang City, reported that his machine has been used very well, just because there was a lack of lubricating oil during an operation, and a recycled oil was added, resulting in a comprehensive decline in the performance of the machine, and finally the problem was solved after overhaul.

4. Improper use of sealant on engine cover pads. After the use of sealant in the partial cover pad, the excess glue is easy to enter the gearbox, due to the long working and suction of the oil pump, the sealant is easy to block the oil inlet hole, so that the crankshaft and connecting rod can not be effectively lubricated.

5. The oil leakage of the fuel tank cover is sealed with film paper. After sealing the fuel tank, a long time of work produces negative pressure in the fuel tank, resulting in insufficient oil intake, so that the machine emits black smoke and insufficient power when working.

6, diesel atomization is not good, only change the nozzle. In addition to the problem of oil nozzle, diesel atomization is mostly caused by the wear of high-pressure oil pumps, small pressure and low oil volume.

7. Tighten the screws on the body. The micro cultivator is mostly equipped with an aluminum alloy box engine, and the hardness of the aluminum alloy is obviously not as good as ductile iron, so all the screws on the fuselage must be in accordance with the prescribed torque force, especially the cylinder head screws, and a little attention will be "drawn". And try not to tighten the screws when the heat is applied.

8. Dismantle the air shield and wind shield of the air cooler. Some operators do not know the role of the wind shield and the wind shield, thinking that it is something that blocks the soil, but it can be dismantled arbitrarily, resulting in the wind of the fan can not be concentrated, losing the cooling effect.
