These details cannot be ignored when working with
a small excavator
1. Remove the soil on the surface of the excavator and check whether there are loose fasteners.
2, if the small excavator is not used in winter, it should be maintained and maintained, and it can only play a better role when it is used again;
3, run the air conditioning system once a month, first let the cab warm the machine, and then let the refrigerant circulate in the air conditioning system for a week, so that the air conditioning system sealing ring to maintain a certain thickness of the oil film to prevent the leakage of refrigerant. Check whether the excavator electric control switch is normal;
4, the air filter can not be removed, with cotton yarn dipped diesel ignited, put in the intake pipe to start the ignition, so that the start of the external dusty air without filtering directly into the cylinder, resulting in piston, cylinder and other parts of the abnormal wear, will also lead to the diesel engine running poorly, damage to the machine.
5, low temperature load operation consequences are serious: will cause serious wear of machinery. Therefore, after the diesel engine starts to ignite in winter, it should idle at a low speed for a few minutes, until the cooling water temperature reaches 63 ° C before it can be put into load operation.
