As a crucial piece of equipment in construction, mining, and other industries, excavators are often used heavily. For second-hand excavators, proper daily maintenance is especially important. Adequate care not only extends the service life of a second-hand excavator but also ensures optimal performance during operation, improving work efficiency. So, how can you maintain your second-hand excavator daily? Here are some tips to help you better maintain your excavator.
1. Regularly Check Hydraulic Oil
The hydraulic system is the "heart" of the excavator, and ensuring the hydraulic oil quality and level is key to maintaining a second-hand excavator machine. Before each use, check the hydraulic oil level and quality. If the oil level is low, refill it in time. If the oil looks murky or smells unusual, it’s best to change it to avoid affecting the excavator's performance.
2. Keep the Engine Clean
A clean engine is essential for the normal operation of a second-hand excavator. After each work session, use an air compressor or cleaner to remove dust, dirt, and debris from the engine surface and radiator to ensure proper engine cooling. Regularly check the air filter to make sure it is clean, preventing dirt from entering the engine and affecting its performance.
3. Check the Cooling System
Second-hand excavators tend to overheat under heavy load, so regular inspection of the cooling system is crucial. Check the coolant level and quality regularly to ensure the cooling system is working properly. If you notice coolant leakage or a significant decrease in level, promptly refill it and check the piping for issues.
4. Monitor Track and Tire Wear
The tracks or tires of a second-hand excavator is key components that make contact with the ground and affect the machine's stability and efficiency. Regularly check the track tension to ensure the tracks are properly tightened, preventing excessive wear due to looseness. For tire excavators, check the tire pressure and wear conditions, and replace or repair the tires if necessary.
5. Regularly Change Oil Filters and Air Filters
Changing engine oil, oil filters, and air filters regularly is an important part of second-hand excavator maintenance. Oil filters help remove impurities from the engine oil, extending the engine's lifespan. Air filters ensure that the air entering the engine is clean, preventing dust and debris from harming the engine. Depending on your working environment, it’s recommended to replace these every 200-300 hours.
6. Inspect the Electrical System
Regular checks of the electrical system are necessary for excavadoras de segunda mano. Inspect the battery level, clean the battery terminals, and avoid poor contact that could cause startup issues or power shortages. Also, regularly check for worn electrical cables to ensure the electrical system is functioning properly.
7. Maintain the Lubrication System
Regularly lubricating the bucket, joints, and swing parts of the excavator helps reduce friction and wear, extending the lifespan of these components. After each work session, lubricate the moving parts with oil to prevent any joint parts from seizing or wearing out prematurely.
8. Conduct Regular Full Vehicle Inspections
Periodically conduct a full inspection of the excavator, checking the tightness of all parts, the hydraulic system, engine, and steering system for any irregularities. This is especially important in harsh working environments, where regular checks can help prevent potential issues from causing unnecessary damage.
Daily maintenance of used digger equipment not only extends their lifespan but also boosts work efficiency and reduces the risk of breakdowns. Proper daily maintenance will ensure your second-hand excavator operates efficiently and serves you longer, offering a more reliable return on investment!
