The Kobelco SK200-8 is a powerful hydraulic excavator widely used in various civil engineering projects. However, some users may experience issues with low power on attachments and frequent appearance of the E013 error code, which can affect the machine's performance and reliability. This article summarizes the potential causes of these problems and provides solutions.
Problem Description
Users have reported that their Kobelco SK200-8 excavators experience low power when operating attachments, and the E013 error code appears frequently. The E013 error is typically associated with insufficient hydraulic pressure or a malfunctioning sensor. The low power issue is often manifested by the inability to properly operate attachments, resulting in reduced work efficiency.
Problem Analysis
The low power issue with attachments and the E013 error code on the Kobelco SK200-8 excavator are often caused by hydraulic system malfunctions, sensor issues, or electrical faults. By performing regular maintenance, inspecting sensors, and troubleshooting electrical systems, operators can resolve these problems and restore the machine’s full performance. Regular care and inspections are effective preventive measures. If the problem persists, it is advisable to seek help from a professional technician.

The low power issue is often manifested by the inability to properly operate attachments, resulting in reduced work efficiency.
Problem Analysis
- Hydraulic System Issues: Insufficient hydraulic pressure is a common cause of low attachment power. Issues such as malfunctioning hydraulic pumps, clogged filters, or damaged pipes can lead to inadequate power delivery to the attachments.
- Sensor Malfunction: The E013 error code is often related to a failure in the hydraulic pressure sensor. If the sensor fails to accurately read system pressure, it can trigger the error code and cause the attachment power issue.
- Electrical System Faults: Any faults in the electrical system, particularly those related to hydraulic control valves and sensors, can result in abnormal attachment operation and trigger error codes.
- Hydraulic Oil Quality or Level Issues: The quality and level of hydraulic oil are critical to the hydraulic system's performance. If the oil is dirty or the level is low, the hydraulic system may not function properly, leading to reduced attachment power.
- Check the Hydraulic System: Begin by inspecting the hydraulic oil’s quality and level. Ensure that the oil is clean and at the appropriate level. If the oil is contaminated or the level is low, replace or top off the hydraulic oil. Additionally, check the hydraulic pump, filter, and pipes for blockages or damage.
- Inspect the Sensors: The E013 error code indicates a possible sensor failure. Inspect the hydraulic pressure sensor and its electrical connections for any issues. If the sensor is faulty, consider replacing it.
- Check the Electrical System: Inspect the electrical control system, including the hydraulic valves and wiring, to ensure that there are no power interruptions or poor connections. If any electrical issues are found, repair or replace the affected components.
- Use Diagnostic Tools: Utilize professional diagnostic tools to run a full system check and identify any underlying issues. This can help pinpoint the root cause of the low power and error code more accurately.
- Regular Hydraulic System Maintenance: Periodically change the hydraulic oil and filters, and check the condition of the hydraulic components to prevent the buildup of dirt or excessive wear.
- Regular Sensor and Electrical System Inspections: Regularly inspect sensors and electrical connections to ensure proper operation and avoid power issues caused by electrical faults.
- Pre-Operation Checks: Before starting the machine, check the hydraulic oil level and quality, and ensure the hydraulic system is functioning within normal parameters.
