After the excavator owner buys a new excavator, before the excavator works, he must carefully read the instruction manual of the excavator and use and operate the excavator in strict accordance with the requirements of the instruction manual. In particular, he needs to pay attention to the following points: 1 When choosing fuel for the excavator, you must choose the fuel that matches the excavator model (it is in the manual, and the owner can buy it directly). Before adding fuel to the excavator, it must be precipitated and filtered. Excavator oiler should be clean and free of impurities. 3. The lubricating oil should be kept clean, the quantity of lubricating oil should be sufficient, and it should be replaced regularly. 4. The air filter should be maintained regularly. 5. Pay attention to replenish cooling water, especially don't let the engine work in a state of water shortage. If engine cooling is found, it should be added in time. 6. Be sure to check and tighten the relevant bolts and nuts. Especially connecting rod bolts, bolts on transmission shafts, locking nuts on flywheels, fastening nuts on wheels, etc. 7 Check the water tank and oil tank of the excavator every day before the operation of the excavator, and check whether the excavator has simple maintenance tools. The new machine generally changes the oil and all filter elements every 50 hours, and the gear oil and hydraulic oil can be changed later. The air filter and mechanical filter of diesel filter should be maintained regularly and replaced regularly. The whole car should be buttered once a day. Chengdu Excavator Training School should replace the gear oil, engine oil, engine oil filter, diesel oil filter, oil-water separator and hydraulic oil inlet and outlet pilot filter of the main reducer every 9 10 2000 hours. Replace hydraulic oil, final drive, rotating gear oil, engine oil, hydraulic oil inlet and outlet filters, pilot filters, oil filters and diesel filters every 10 hour. But add butter (grease) every day to check the oil level, and sometimes check the cooling water level. 1 1 Maintenance is divided into five parts, and each part is in accordance with relevant instructions or specifications: engine+walking part+hydraulic part+frame action part+excavator bucket. The emphasis is on lubrication, cleaning and observation of all parts. Especially the oil and hydraulic oil are kept clean, and the rotating shaft is effectively lubricated.
