Common Issues with the Daewoo Solar 55
While the Daewoo Solar 55 is a highly reliable machine, it is not immune to common mechanical problems that can arise due to wear and tear or improper maintenance. Below are some of the most frequently reported issues, along with troubleshooting tips.
1. Hydraulic System Failures
One of the most common complaints from operators of the Solar 55 is hydraulic system failure. Symptoms often include weak or unresponsive movement of the arm, boom, or bucket. This issue can be caused by low hydraulic fluid levels, dirty filters, or leaks in the hydraulic lines.
Troubleshooting:
Electrical problems, such as faulty sensors or a malfunctioning battery, are also prevalent with the Solar 55. Operators may notice warning lights illuminating on the dashboard or the machine failing to start.
Troubleshooting:
As with many tracked machines, the undercarriage of the Daewoo Solar 55 experiences significant wear over time, especially in rugged terrains. This can result in reduced mobility and increased fuel consumption.
Troubleshooting:
Overheating is another issue often reported by users of the Daewoo Solar 55, especially in hot environments. This problem can lead to engine damage if not addressed promptly.
Troubleshooting:
Operators in different industries have shared their experiences with the Daewoo Solar 55, highlighting both its strengths and weaknesses.
1. Construction Sites in Challenging Terrain
In one case, a construction company working on a steep, rocky hillside found the Daewoo Solar 55 to be an invaluable asset due to its compact size and agility. The excavator’s ability to maneuver in tight spaces allowed them to complete trenching work in areas that would have been challenging for larger machines. However, they reported issues with undercarriage wear after prolonged use in such harsh conditions, leading them to invest in more frequent undercarriage maintenance.
2. Agricultural Applications
Farmers in rural areas have also found the Solar 55 useful for tasks like digging irrigation ditches and moving soil. One farmer noted that the hydraulic system worked exceptionally well for lifting heavy loads but experienced occasional delays when the hydraulic fluid became contaminated with dirt after working in particularly muddy fields. Regular maintenance and timely fluid changes helped mitigate this issue.
3. Mining Operations
In mining operations, where heavy lifting and digging are required, the Daewoo Solar 55 has proven to be a durable and reliable choice. However, some users have reported electrical issues, particularly with the battery and alternator, which would cause the machine to fail intermittently. After replacing faulty components and improving maintenance schedules, the issues were resolved.
Conclusion
The Daewoo Solar 55 excavator is a well-regarded piece of machinery in the construction and excavation sectors. Its compact size, fuel efficiency, and performance make it a valuable asset for a wide range of projects. However, like any machine, it is not without its challenges. Regular maintenance, attention to hydraulic systems, and vigilant monitoring of the undercarriage and cooling system are essential for keeping the Solar 55 in top condition.
By addressing common issues such as hydraulic failure, electrical problems, and undercarriage wear early, operators can prolong the life of their Daewoo Solar 55 and avoid costly repairs. Proper maintenance and troubleshooting can significantly enhance the machine's reliability and ensure that it continues to perform optimally in demanding environments.

One of the most common complaints from operators of the Solar 55 is hydraulic system failure. Symptoms often include weak or unresponsive movement of the arm, boom, or bucket. This issue can be caused by low hydraulic fluid levels, dirty filters, or leaks in the hydraulic lines.
Troubleshooting:
- Check Fluid Levels: Low hydraulic fluid is a common cause of poor hydraulic performance. Ensure that the fluid is topped up to the correct level as specified in the user manual.
- Inspect for Leaks: Check all hydraulic hoses, valves, and connections for signs of leakage. Even small leaks can severely affect the efficiency of the hydraulic system.
- Replace Filters: Clogged filters can cause poor hydraulic flow. Regularly replacing hydraulic filters is essential for maintaining the system's performance.
Electrical problems, such as faulty sensors or a malfunctioning battery, are also prevalent with the Solar 55. Operators may notice warning lights illuminating on the dashboard or the machine failing to start.
Troubleshooting:
- Battery Inspection: A weak or dead battery can cause starting issues. Test the battery’s voltage and replace it if necessary.
- Check Fuses and Wiring: Inspect the fuse panel and wiring for any visible signs of damage or corrosion, especially if the machine is experiencing electrical issues like inconsistent power or malfunctioning controls.
- Sensor Calibration: If the problem is related to sensors, consider recalibrating or replacing them.
As with many tracked machines, the undercarriage of the Daewoo Solar 55 experiences significant wear over time, especially in rugged terrains. This can result in reduced mobility and increased fuel consumption.
Troubleshooting:
- Track Tension: If the tracks are too loose or too tight, it can lead to uneven wear. Ensure that the track tension is correctly adjusted according to the manufacturer’s guidelines.
- Inspect Rollers and Idlers: The rollers and idlers support the tracks and need to be regularly inspected for wear and damage. Replace any parts that are excessively worn to prevent further damage.
- Lubrication: Regularly lubricate the undercarriage components to reduce friction and wear.
Overheating is another issue often reported by users of the Daewoo Solar 55, especially in hot environments. This problem can lead to engine damage if not addressed promptly.
Troubleshooting:
- Radiator Cleaning: Dust and debris can clog the radiator and reduce its cooling efficiency. Ensure that the radiator is cleaned regularly, especially when working in dusty or dirty environments.
- Coolant Levels: Low coolant levels can also contribute to overheating. Regularly check the coolant and top it up as necessary.
- Thermostat Functionality: A faulty thermostat can prevent the engine from reaching optimal operating temperatures. If overheating persists, the thermostat should be checked or replaced.
