The SH200-6 is no exception, featuring a robust undercarriage and reinforced structure to handle the wear and tear of demanding tasks. Its longevity and reliability make it a popular choice for contractors who need equipment that can handle tough environments.
Routine Maintenance for the Sumitomo Legest SH200-6
Proper maintenance is essential to ensure the longevity and performance of the SH200-6 excavator. Here are some of the key maintenance tasks operators should perform regularly:
1. Engine Oil and Filter Change
Changing the engine oil and filter is critical to maintaining the engine’s performance and preventing wear. It's recommended to change the oil every 250-500 hours of operation, depending on the manufacturer’s guidelines and the conditions in which the machine is used.
2. Hydraulic System Maintenance
The hydraulic system is the heart of any excavator, and regular maintenance is crucial to keeping the SH200-6 running efficiently. Check the hydraulic fluid levels and inspect for leaks. It's essential to replace the hydraulic fluid and filters as recommended to avoid system failures.
3. Air Filter Replacement
The air filter prevents dirt and debris from entering the engine and causing damage. Over time, air filters can become clogged, reducing engine efficiency and performance. Check and replace the air filter regularly, especially in dusty conditions.
4. Undercarriage Inspection
The undercarriage is subjected to significant stress, especially in rough terrain. Inspect the tracks, sprockets, and rollers regularly for wear and damage. Proper maintenance of the undercarriage ensures better stability and longer life of the excavator.
5. Cooling System Maintenance
The SH200-6 is equipped with a robust cooling system to prevent overheating. Regularly check the coolant levels, hoses, and radiator to ensure proper function. Overheating can lead to engine damage, so maintaining the cooling system is essential.
6. Battery Check
Ensure the battery is clean and fully charged. If the excavator is frequently used in cold environments, consider using a battery warmer to prevent starting issues.
Common Issues with the Sumitomo Legest SH200-6
While the SH200-6 is a durable and reliable machine, like any piece of heavy equipment, it is not immune to issues. Below are some common problems that operators may encounter:
1. Hydraulic System Leaks
Hydraulic leaks can occur due to damaged hoses, seals, or fittings. A hydraulic leak can result in loss of power and performance, making it essential to address leaks promptly. Operators should routinely check the hydraulic system for leaks, particularly in high-stress areas.
Solution: Inspect hoses and seals for wear and tear. If any parts are damaged, replace them immediately to prevent further issues.
2. Engine Overheating
Overheating can be a problem in any machine, and the SH200-6 is no exception. Factors such as low coolant levels, a malfunctioning radiator, or a dirty air filter can lead to engine overheating.
Solution: Regularly check the coolant levels and ensure the radiator is clean and functioning properly. If the problem persists, inspect the thermostat or cooling fan.
3. Track and Undercarriage Issues
The undercarriage of the SH200-6 is subject to extreme wear, especially in rocky or uneven terrain. Worn tracks, rollers, or sprockets can compromise the stability and movement of the excavator.
Solution: Regularly inspect the undercarriage for signs of wear or damage. Replace worn parts and adjust the track tension to maintain proper movement.
4. Fuel System Problems
Fuel system issues, such as clogged fuel filters or faulty injectors, can lead to poor engine performance. If the engine struggles to start or runs unevenly, the fuel system might be the culprit.
Solution: Replace the fuel filters as recommended by the manufacturer. If the issue persists, inspect the fuel injectors and fuel lines for blockages or damage.
5. Electrical System Failures
Electrical issues, such as a dead battery or faulty wiring, can cause starting problems and erratic machine behavior. These issues are typically related to poor maintenance or external damage.
Solution: Check the battery for corrosion and ensure that the wiring is intact. Replace any damaged components to prevent further electrical issues.
Conclusion
The Sumitomo Legest SH200-6 is a reliable and powerful excavator known for its efficiency, comfort, and durability.
