When using an excavator in winter, you need to pay attention to the following things

1. Heating the engine: At low temperatures, the cold start of the engine may be affected. Before using the excavator, especially on cold mornings, the engine should be heated in advance. An electric heater or other heating device can be used to warm the engine in advance, which can improve the reliability and efficiency of starting.

2. Check the antifreeze: Make sure the antifreeze concentration in the engine cooling system is appropriate. The higher the concentration of antifreeze, the stronger the cold resistance. If the antifreeze concentration is insufficient, it may cause poor cooling of the engine in low temperature environments, or even freeze damage.

3. Check the battery status: Low temperature will affect the performance of the battery, so you should check the battery status and voltage before using the excavator in winter. Make sure the battery is properly and fully charged, and replace aging or damaged batteries in a timely manner.

Replace with suitable lubricating oil and fuel: In areas with cold weather, it is necessary to use lubricating oil and fuel that meet the requirements of low-temperature environments. These low-temperature lubricants and fuels have better fluidity and antifreeze properties, which can ensure the normal operation of the engine. As for engine maintenance, the following measures can be taken:

4. Replace the engine oil and filter regularly: Change the engine oil and filter regularly according to the time and mileage specified by the manufacturer. The quality and cleanliness of engine oil are crucial to the normal operation of the engine. Replacing new engine oil and engine filter can protect the engine and improve its life and performance.

5. Clean the engine compartment: Clean the engine compartment regularly to ensure that there is no accumulation of dust, mud and impurities around the engine. These impurities may clog the radiator, affect the engine's cooling effect, and lead to problems such as overheating.

6. Check and maintain the cooling system: Check the engine cooling system regularly to ensure that the coolant is at the appropriate level, and replace aging or damaged coolant in a timely manner. The pumps, radiators, and cooling ducts within the cooling system should also be cleaned to ensure they are functioning properly.

7. Regularly check the battery and wire connections: Check the battery's electrolyte level and wire connection status to ensure normal operation of the battery. Clean oxide from battery terminals and wire connections to maintain good electrical contact.

8. Regularly check and replace the air filter: During agricultural operations, excavators are prone to inhaling dust and impurities, so the air filter needs to be checked and replaced regularly to prevent the engine air intake system from being contaminated.

9. In short, when using an excavator in winter, you need to pay special attention to the heating and protection of the engine, regularly replace the oil and machine filter, clean the engine compartment and cooling system, and keep the battery and wires in good condition. This ensures smooth operation of the excavator in harsh winters and extends the service life of the engine.
