Excavator if sit idle during the winter, should be properly kept and maintenance. When used again to play the best efficiency, maintenance measures are as follows:

1) to clean up the dirt on the surface of the excavator, check whether loose fasteners.

2) check antifreeze oil level and oil level is normal, check whether the oil oil is normal, check the fuel level of antifreeze.

3) if the weather is extremely cold, excavator down time is very long, the engine cooling fluid discharge clean, please. In order to prevent the battery feed at the same time, the battery must be open to a warm place for storage.

4) start the engine running once a month, if antifreeze oil level and oil level is lower than the normal oil level, please add to normal after the start. As the cold weather will key in the preheating to preheat the light after several repeated preheating (), then start the engine, idle running 5-10 minutes without load for each oil cylinder action 5-10 times, each time is smaller than range 5-10 mm. Finally make the engine revolutions highest fast operating cylinder movement 5-10 times each, at the same time operating turning around and walking before and after the three times. Until the system temperature can work up to 50-80 degrees, continue to make all the working device for 5-10 minutes to stop the engine.

5) run a monthly air conditioning system, first of all let the cab to heat up, and then let the refrigerant in the circulation of air conditioning system for a week, keep the air conditioning system of the sealing ring in a certain thickness of oil film, prevent refrigerant leakage. Check excavator electric control switch is normal.

6) concrete maintenance items refer to the various models of operation and maintenance manuals.

7) to replace for diesel - between 10-30 models, it depends on the area, will add to the north - number of diesel, in addition to replace diesel oil filter, oil to replace local applicable thickening mechanism for oil, oil filter is replaced, where oil leakage of the hydraulic system to timely replacement, conditional should be insulated tank.

8) cooling system to check whether the rubber hose is aging and fracture, if there are any questions you would like to change in time because these places in the winter are more likely to problems. If there are conditions to provide hot water, water tank best heating water that can better every day started the engine, but must pay attention to don't forget to water. Is not recommended with antifreeze is because in extremely cold areas with antifreeze are less likely to start the engine. If it is new and original with antifreeze don't replaced but should pay attention to the vehicle's heat preservation, can look for local excavator maintenance teacher consult more suited to local conditions, for reference only.
