Kobelco has designed the SK035-2 with easy maintenance in mind. Accessible service points allow for quick checks of oil levels, air filters, and other essential components, reducing downtime for maintenance and repairs.
While the Kobelco SK035-2 is generally a reliable machine, it can encounter certain issues that need attention. Here are some common problems that operators may face, along with solutions to resolve them.
- Hydraulic System Leaks
Hydraulic leaks are a common issue in many mini-excavators, including the SK035-2. Leaks can occur due to wear on hoses, seals, or fittings. A hydraulic leak can lead to reduced performance, lower fluid levels, and potential damage to the system.
How to Fix:- Inspect all hydraulic lines, fittings, and hoses for signs of wear or cracks.
- Replace any damaged or leaking hoses and fittings promptly.
- Check the hydraulic fluid regularly and top it off as needed.
- Ensure that the pressure relief valve is functioning correctly.
- Inspect all hydraulic lines, fittings, and hoses for signs of wear or cracks.
- Engine Overheating
Engine overheating can cause significant problems and, if left unchecked, may lead to permanent engine damage. This issue is typically caused by low coolant levels, a clogged radiator, or a malfunctioning cooling fan.
How to Fix:- Check the coolant level regularly and refill if necessary.
- Inspect the radiator for any blockages or debris that may be obstructing airflow.
- Ensure that the cooling fan is functioning properly, and clean it if necessary.
- Check the coolant level regularly and refill if necessary.
- Electrical Issues
Electrical problems, such as a dead battery or faulty wiring, can prevent the excavator from starting or cause intermittent electrical failures. Electrical issues are often caused by loose connections, corrosion, or damage to wiring.
How to Fix:- Inspect all electrical connections, ensuring that they are tight and free from corrosion.
- Check the battery charge and condition. Replace the battery if it is not holding a charge.
- Inspect the alternator and wiring for any signs of damage or wear.
- Inspect all electrical connections, ensuring that they are tight and free from corrosion.
- Track Wear and Tear
The tracks on the SK035-2 are subject to wear, especially if the excavator is frequently used in rocky or abrasive conditions. Worn-out tracks can cause the machine to lose traction and reduce its ability to maneuver effectively.
How to Fix:- Regularly inspect the tracks for signs of wear, cracks, or damage.
- Adjust the track tension to ensure it is neither too loose nor too tight.
- If the tracks are excessively worn, consider replacing them with new ones.
- Regularly inspect the tracks for signs of wear, cracks, or damage.
- Control Valve Malfunctions
A malfunctioning control valve can cause a variety of issues, from erratic movements to complete loss of functionality in certain parts of the machine. This can be caused by worn seals or contaminants in the hydraulic system.
How to Fix:- Inspect the control valve for signs of leaks or damage.
- Flush the hydraulic system to remove any contaminants.
- Replace any damaged seals or components within the valve.
- Inspect the control valve for signs of leaks or damage.
Proper maintenance is essential to ensure the longevity and performance of your Kobelco SK035-2. Regular upkeep can help prevent many of the issues mentioned above. Here are a few maintenance tips to keep your mini-excavator in top condition:
- Routine Fluid Checks
Regularly check the hydraulic fluid, engine oil, and coolant levels. Low or contaminated fluids can lead to inefficient performance and damage to components.
- Track Tension and Alignment
Keeping the track tension properly adjusted will prevent unnecessary wear and extend the life of the undercarriage. Regularly inspect the track rollers, sprockets, and idlers for any signs of wear.
- Clean the Air Filter
A clogged air filter can reduce engine efficiency and increase fuel consumption. Clean or replace the air filter as needed to ensure optimal engine performance.
- Lubricate the Pins and Bushings
Regularly lubricate the moving parts of the excavator, including the pins and bushings, to reduce friction and prevent premature wear.
- Scheduled Service Intervals
Follow the manufacturer’s recommended service intervals for oil changes, hydraulic filter replacements, and other essential maintenance tasks.
