The machine typically comes with a powerful engine and a hydraulic system capable of handling a variety of attachments, such as buckets, hammers, and other tools, making it versatile for different tasks.
Common Issues with the Furukawa FL200i
While the Furukawa FL200i is generally considered reliable, operators may encounter a few common issues that could affect performance. Some of these issues, if left unaddressed, may lead to costly repairs or prolonged downtime. Here are some of the most frequently reported problems:

1. Hydraulic System Problems
   The hydraulic system is the heart of the FL200i’s operations, responsible for providing the necessary force for movements such as lifting, digging, and swinging. A common issue that operators face is a malfunction or drop in hydraulic power. This can occur due to low hydraulic fluid, leaks, or damaged components.
   Symptoms:
   • Sluggish or unresponsive movements of the arm, boom, or bucket.
     
   • Sudden loss of hydraulic pressure.
     
   • Fluid leaks around hydraulic hoses or pumps.
     
   Troubleshooting:
   • Inspect hydraulic fluid levels and top them up if low.
     
   • Check for visible leaks in hoses, valves, and connections.
     
   • Replace or repair damaged seals and hoses.
     
   • If the issue persists, have the hydraulic pumps and valves inspected by a professional technician.
     
2. Engine Performance Issues
   The FL200i is powered by a diesel engine that must perform efficiently to power the hydraulic system and move the machine. Common engine issues include poor fuel efficiency, starting difficulties, or irregular engine speed.
   Symptoms:
   • Engine misfiring or stalling during operation.
     
   • Difficulty starting the machine, especially in cold weather.
     
   • Reduced power output during demanding tasks.
     
   Troubleshooting:
   • Inspect the fuel system, including filters and injectors, for blockages or damage.
     
   • Check the air intake and exhaust systems for clogging.
     
   • Replace or clean the fuel filters if necessary.
     
   • Ensure the battery is fully charged and in good condition, especially for starting difficulties.
     
3. Electrical System Failures
   Electrical malfunctions can affect various aspects of the Furukawa FL200i, including lights, sensors, and operational functions. Common electrical issues can stem from wiring failures, sensor malfunctions, or issues with the alternator.
   Symptoms:
   • Malfunctioning lights, indicators, or warning systems.
     
   • Failure of certain operational controls, such as the joystick or cabin air conditioning.
     
   • Unresponsive sensors or error codes displayed on the monitor.
     
   Troubleshooting:
   • Inspect all wiring and connections for visible wear, corrosion, or loose connections.
     
   • Test sensors and switches to ensure they are functioning correctly.
     
   • Check the alternator and battery for proper charging and power output.
     
4. Track and Undercarriage Wear
   The undercarriage and tracks of the FL200i are subjected to significant wear due to the constant stress of moving over rough terrain. Track issues are common, including track misalignment, wear, and even track breaks.
   Symptoms:
   • Uneven track wear or visible damage to the track links.
     
   • Noise or vibration during movement.
     
   • Difficulty in maintaining track tension.
     
   Troubleshooting:
   • Inspect the tracks for signs of wear, cracks, or missing bolts.
     
   • Check the track tension and adjust as necessary.
     
   • Replace worn-out or damaged track components.
     
   • Regularly clean the undercarriage to remove debris that can cause excess wear.
     

Regular Maintenance for Optimal Performance
Maintaining the Furukawa FL200i is essential for prolonging its lifespan and avoiding unnecessary downtime. Here are some essential maintenance tips to keep the excavator in peak condition:

1. Regular Hydraulic System Maintenance
   The hydraulic system requires regular attention to ensure smooth performance. Always check fluid levels, clean or replace filters, and inspect hoses for wear. Changing the hydraulic fluid according to the manufacturer’s recommendations is critical for maintaining pressure and avoiding contaminants in the system.
   
2. Engine Oil and Filter Changes
   Just like any heavy machinery, the engine oil needs to be changed regularly to ensure the engine runs smoothly. Following the manufacturer’s guidelines for oil type and change intervals will prevent engine wear and improve fuel efficiency.
   
3. Track and Undercarriage Care
   The tracks and undercarriage should be cleaned regularly to remove debris and dirt. This helps prevent unnecessary strain on the components and extends the life of the tracks. Track tension should be checked, and adjustments made based on manufacturer recommendations.
   
4. Regular Electrical Checks
   Inspect the electrical components, such as sensors, batteries, and wiring, on a regular basis to prevent failure. Clean connections and replace any faulty parts promptly to avoid electrical issues during operation.
   
5. Monitor Fluid Leaks and Address Them Quickly
   Fluid leaks can cause major issues if not addressed in time, especially within the hydraulic system. Regularly inspect for any visible leaks and have them repaired promptly to avoid low fluid levels and loss of pressure.
