1. After the heater has been running for a period of time (depending on user usage), unscrew the glow plug to clean carbon deposits. If the glow plug wire is burned out, remove and replace it with a new one.
2. If carbon deposits are excessive, causing reduced thermal efficiency, clean the heat sink on the inner wall of the water jacket and the carbon deposits in the combustion chamber.
3. If the air intake pipe, exhaust pipe, and oil drip pipe of the heater main unit are found to be clogged with mud, clean and unblock them promptly. Keep the heater compartment clean, and strictly prohibit placing flammable debris around it.
4. Ensure the fuel tank, fuel lines, and fuel filter solenoid valve are clean to prevent dirt from clogging the fuel circuit.
5. Use antifreeze suitable for the ambient temperature as the circulating heating medium in the heater's circulation system.
6. Inspect the heater water pump regularly according to user usage. If the mechanical seal component leaks or the pump is difficult to start and operate, repair it promptly.
7. The automatic control box, fuel filter solenoid valve, and other electrical components on the heater main unit should be maintained according to general low-voltage electrical maintenance methods. All performance parameters of the automatic control box are carefully debugged by the manufacturer before shipment; users should not modify them without authorization.
8. Ensure the thermal control component is in good condition and inspect it regularly. If the micro switch malfunctions or is damaged, replace it promptly.
9. The main motor used in the heater normally requires no maintenance for 5000 hours of operation. If it malfunctions due to prolonged use or other reasons, inspect it, check carbon brush wear or bearing lubrication, and add grease or replace carbon brushes if necessary.
10. During warm seasons when the heater is not in use, start it 4 to 5 times periodically, each time running for about 5 minutes, to ensure normal operation when used next time.
