- Inspect and replace fuel filters as necessary.
- Bleed the hydraulic system to remove any trapped air.
- Test and clean or replace fuel injectors if needed.
- Clogged fuel filters or fuel lines restricting fuel flow.
- Hydraulic System Failures
Issues with the hydraulic system can lead to a loss of power or functionality in the boom, arm, or bucket.
Possible Causes:- Low hydraulic fluid levels or contaminated fluid.
- Worn or damaged hydraulic pumps or valves.
- Leaks in hydraulic hoses or fittings.
- Regularly check and maintain hydraulic fluid levels and quality.
- Inspect hydraulic components for wear and replace as necessary.
- Address any leaks promptly to prevent further damage.
- Low hydraulic fluid levels or contaminated fluid.
- Engine Overheating
Overheating can cause significant damage to the engine if not addressed promptly.
Possible Causes:- Clogged radiator or cooling fins restricting airflow.
- Low coolant levels or old coolant.
- Faulty thermostat or water pump.
- Regularly clean the radiator and cooling system components.
- Check and maintain proper coolant levels and replace as needed.
- Test and replace the thermostat or water pump if malfunctioning.
- Clogged radiator or cooling fins restricting airflow.
