1.Compressor maintenance and maintenance
（1） Check refrigerant level regularly
A low refrigerant level may cause the compressor to overheat and damage. You are advised to check the refrigerant level every six months or every time you replace the air conditioner filter element.
Level check requires professional personnel, please contact the authorized maintenance station.
（2）Clean heat sink and condenser
Regularly clean the dust and debris on the heat sink and condenser to ensure good heat dissipation effect.
It can be cleaned using a soft brush or compressed air.
（3）Check belt tension
Regularly check the tension of the compressor belt, too loose or too tight belt will lead to abnormal operation of the compressor.
Belt tension should be kept within the manufacturer’s recommended range.
（4）Pay attention to abnormal noise and vibration
If abnormal noise or vibration occurs during operation, stop using the compressor immediately and contact professional personnel.
（5）Use genuine refrigerant and freezing oil
The use of non-genuine refrigerant and refrigerant oil can cause compressor damage and affect air conditioning system performance.
2.starter maintenance and maintenance
（1） Check the battery status regularly
Insufficient battery voltage will cause the starter to operate weak, it is recommended to check the battery voltage every six months or each maintenance.
The battery voltage should be above 12.4V.
（2）Check the terminal
Regularly check whether the starter terminal is loose or corroded, and tighten or replace it in time.
（3）Pay attention to the starting time
Each starting time should not exceed 10 seconds, and the continuous starting interval time should be greater than 15 seconds.
（4）Avoid frequent starts
Frequent starting may cause the starter to overheat. It is recommended that the interval between starting is greater than 15 seconds.
（5）Regular cleaning and lubrication
Clean the dust on the surface of the starter regularly and lubricate with lithium grease if necessary.
3.Generator maintenance and maintenance
（1）Check belt tension regularly
Regularly check the tension of the generator belt, too loose or too tight belt will affect the performance of the generator.
Belt tension should be kept within the manufacturer’s recommended range.
（2）Check the terminal
Periodically check whether the generator terminal is loose or corroded, and tighten or replace it in time.
（3）Pay attention to abnormal noise
If abnormal noise is found during the operation of the generator, stop using it immediately and contact a professional to check.
（4） Regular cleaning and lubrication
Clean the dust on the generator surface regularly, and use lithium grease to lubricate if necessary.
（5）Pay attention to battery voltage
Check the battery voltage regularly, too high or too low voltage can affect the generator performance.
It is recommended that the battery voltage be between 13.5 and 14.5V.
