Precautions for maintenance After buying a new machine, before using the engine, it is necessary to carefully read the instruction manual of the machine. Users should pay special attention to the basic requirements of the book: (1) Use the specified grade of fuel, use Before it is fully settled and filtered, the oiler must be kept clean. (2) The lubricating oil should be kept clean, and the quantity to be added must be sufficient, and it should be changed regularly. The use of the brand should be consistent with the regulations. (3) The air cleaner should always pay attention to maintenance. (4) Care should be taken to add cooling water, especially if the engine is not to be operated in a water shortage. (5) Always pay attention to check and tighten the relevant bolts and nuts, especially the connecting rod bolts, the bolts on the drive shaft and the lock nuts on the flywheel, and the fastening nuts on the wheels. If the user buys a new camera and really does it in accordance with the above basic requirements, then the life of the camera can be greatly extended. After buying a new machine, do not carry the load operation immediately. Follow the instructions in the manual to run it. After the running-in is completed, the machine oil filter is cleaned and residual impurities in the engine oil are removed. If necessary, the engine oil must be replaced and the oil pan cleaned. When the new machine operates, it must strictly follow the requirements of the manufacturer's instructions, do not overload, do not overspeed, do not overfeed, and do not work long-term overload. Can not be arbitrarily modified on the new machine and arbitrarily increase the speed of the engine. In order to make the machine run faster, some users may arbitrarily adjust the fuel supply and pressure of the high-pressure oil pump, and some of them tie the governor spring wire. This is even more wrong. 2. Notes on the failure of the new machine: (1) When the new machine fails within the validity period of the "Three Guarantees" and needs to be repaired by the manufacturer, it must be repaired by the purchase invoice and the "three guarantees" voucher to the designated maintenance point (generally Where to buy, go there to repair), after the repair is completed on the "three bags" voucher well maintained records. (2) In the new machine "Three Guarantees" period, the foreign operation (such as running and transportation) fails. The operator should not immediately disassemble the machine. He shall contact the seller in time to negotiate maintenance matters. After obtaining the consent of the seller, the machine can be disassembled on the spot. repair. (3) If the new machine has an accident due to quality problems during the validity period of the “Three Guaranteesâ€: 1. Properly protect the site and contact the seller in a timely manner. 2. Ask the local quality and technical supervision department to go to the scene to inspect, if necessary, to issue a written certificate and keep the damaged spare parts. 3. If the casualties are caused, the public security organs and the traffic police department shall also conduct on-site investigation and evidence collection and issue written certification materials to prepare them for use in the future. 3. After the new machine is used, some users only use it seasonally after purchasing the new machine. After using it, they will be allowed to use it for water and sun, until the season comes. At this point, the machine can not rotate, such as the engine cylinder, piston rings, valves, seats, pipes, etc. are all rusted, the loss is very large. In order to avoid this from happening, the following special maintenance must be performed on the machine that is used for a long time and then reused: (1) Clean the machine's appearance, including farm implements. (2) Put the machine in a ventilated and dry place. (3) Discharge all the cooling water from the water pipes and tanks. (4) Start the machine for about 20 seconds to volatilize the residual moisture in the body. (5) Shake the crankshaft, set the loom at the beginning of the compression stroke (at this time, the intake and exhaust valves are closed, the high-pressure pump wheel is not pressed by the camshaft of the camshaft), keep this position and move The trachea is bandaged (the purpose is to prevent insects, dust, and impurities from getting inside). (6) Apply a layer of fresh engine oil to the parts of the agricultural machinery and the machine that are liable to rust. (7) After every two months of parking, untie the packing of the inlet and exhaust nozzles, start the machine for more than ten seconds (without cooling water), place the machine in the original parking position, and re-wrap the inlet and exhaust. Nozzle. Like this kind of maintenance, the machine can work when it is needed, and the phenomenon of rusting will not happen.
