Cleaning and maintenance before storage
1. Clean the exterior - Wipe the body with a dry cloth to remove dust and oil.- Check the air inlet and outlet to ensure there is no obstruction (such as debris, snow, etc.).
2. Check the fuel system - Make sure there is no leakage in the fuel tank and the fuel line connections are secure.- Drain any water or impurities from the bottom of the tank
3. Check the ignition system - Check the ignition needle and combustion chamber for carbon deposits.- If ignition is difficult, it may be due to carbon deposits or gap problems on the electrodes, which need to be adjusted or replaced.
4. Run Test - Allow the equipment to idle for 90 seconds before shutting down to avoid carbon deposits caused by sudden shutdown.
Regular maintenance (monthly or every 50-100 hours of operation)
1. Replace the fuel filter - Replace the filter regularly according to the frequency of use (recommended every season or every 500 hours).
2. Cleaning the combustion chamber - Remove the burner and use a soft brush to remove carbon deposits to avoid affecting combustion efficiency.
3. Check the fan and motor - Clean the dust from the fan blades and check the lubrication of the bearings (add high-temperature lubricating oil if necessary).
4. Circuit inspection - Check whether the wires are aging and the connectors are loose to avoid the risk of short circuit.
Seasonal maintenance (long-term disuse or season change)
1. Fuel system treatment - Drain remaining fuel in the tank or add fuel stabilizer to prevent deterioration.- Clean the oil pump and nozzle to avoid colloid blockage.
2. Rust-proof treatment - Apply anti-rust oil to the rust-prone parts of the metal casing.- Store in a dry and ventilated place, avoid moisture.
Common troubleshooting
| Failure symptoms | Possible causes | Solutions
| Failure to ignite | Low fuel/faulty/blocked spark plug | Check fuel level, clean spark plug or replace |
| Black smoke | Incomplete combustion/insufficient air intake | Clean combustion chamber, check air filter |
| Excessive noise | Fan loose/bearing lacks oil | Tighten screws and lubricate bearings |
| Insufficient heat output | Filter clogged/poor fuel quality | Replace filter element, use graded diesel |
Safety precautions
1. Be sure to stop the machine and disconnect the power supply/oil circuit before maintenance.
2. Operation in confined spaces is prohibited.
3. Use original accessories and do not modify the fuel system.
4. Waste oil/filter element shall be handled in accordance with environmental protection requirements.
hint :
- It is recommended to have a comprehensive inspection by a professional technician every year.
- Record the date and content of each maintenance to facilitate tracking of equipment status.
