The Features of the IHI 35N Mini Excavator
The IHI 35N is designed to be a powerful, yet compact and easy-to-operate machine. It is equipped with a range of features that make it ideal for a variety of tasks:

1. Powerful Engine: The IHI 35N is equipped with a reliable engine that provides ample power for digging, lifting, and other heavy-duty tasks. The engine's output ensures that the machine can handle tough conditions while still maintaining fuel efficiency.
   
2. Hydraulic System: The excavator features a robust hydraulic system capable of powering attachments and operating the boom, arm, and bucket with precision. Its hydraulic performance ensures smooth operation during lifting, digging, and trenching tasks.
   
3. Compact Size: One of the standout features of the IHI 35N is its compact size, allowing it to work in spaces where larger machines cannot fit. Whether you're working in tight urban environments, alongside existing structures, or in smaller residential jobs, the 35N excels at providing the power of a larger excavator in a more nimble package.
   
4. Maneuverability: With its zero-tail-swing design, the IHI 35N can rotate within its own footprint, allowing for precise positioning and movement in confined spaces. This makes it perfect for jobs where access is limited or where large machinery simply won't fit.
   
5. Operator Comfort: IHI has designed the 35N with operator comfort in mind. The spacious cabin offers good visibility, ergonomic controls, and climate control to keep operators comfortable during long shifts. The layout of the controls is intuitive, which is especially beneficial for new operators.
   
6. Versatility: The 35N can handle a range of attachments, such as augers, breakers, and buckets, making it a versatile machine that can adapt to different job requirements. Its flexibility allows it to be used across multiple industries, from landscaping to light construction.
   

Performance and Capability
The IHI 35N is designed to balance power with efficiency. With its relatively small size, it still offers excellent lifting capacity and digging depth. Whether you're excavating soil for a new foundation, trenching for utilities, or demolishing a small structure, the 35N provides the power and precision required for the job.
The mini-excavator’s hydraulic system is one of its most praised features, offering smooth operation and quick cycle times for both digging and lifting. Its strong lifting capacity makes it ideal for material handling tasks, and its digging depth is competitive for its class. Operators can rely on the IHI 35N to efficiently handle medium to light-duty tasks without feeling restricted by its compact size.
Common Problems and Considerations
While the IHI 35N is generally considered a reliable and efficient machine, like all equipment, it can face certain challenges over time. Here are some of the issues that have been reported by users:

1. Hydraulic System Performance: Some users have noted that the hydraulic performance can diminish if the machine is not properly maintained, leading to slower response times and less efficient operation. Hydraulic fluid levels should be checked regularly, and any leaks should be repaired immediately to ensure the system is functioning optimally.
   Solution: Regular hydraulic system maintenance, such as fluid checks and filter replacements, is essential to keep the 35N’s performance consistent. Operators should ensure that there are no airlocks in the hydraulic system and that the oil is free of contaminants.
   
2. Track and Undercarriage Wear: Given the nature of the 35N’s work, the undercarriage is subject to significant wear, particularly if the machine is used in harsh conditions or on rough terrain. Track tension can be a concern, and if left unchecked, it can lead to premature wear and reduced traction.
   Solution: Regular inspection of the tracks and undercarriage is vital. Adjust the track tension as needed, and replace any worn-out parts to ensure smooth operation and longevity of the tracks.
   
3. Engine Performance: Like all machines, the engine of the IHI 35N can face issues related to air filters, fuel systems, and exhaust systems. Fuel delivery problems, dirty filters, and clogged injectors can cause engine performance issues, such as a loss of power or difficulty starting.
   Solution: Regular engine maintenance, including changing fuel filters, air filters, and ensuring proper exhaust flow, will help maintain engine performance. Additionally, using high-quality fuel and additives can improve the lifespan and efficiency of the engine.
   
4. Electrical System Failures: Electrical components, such as lights, gauges, and the battery system, are often subject to wear over time. Users have noted that occasional electrical failures, such as non-responsive gauges or problems with the starter, can occur.
   Solution: Regular inspection of the electrical components, including checking for corrosion on terminals, loose wiring, and the condition of the battery, is necessary. Keeping the electrical system clean and well-maintained will reduce the risk of failures.
   

Maintenance Tips for Longevity
To maximize the life of your IHI 35N mini-excavator, it’s important to adhere to a regular maintenance schedule. Here are some tips for ensuring your machine runs smoothly:

1. Fluid Checks: Regularly check the engine oil, hydraulic fluid, and coolant levels to ensure that all systems are properly lubricated and cooled. Contaminants in the fluids can lead to system failure, so it’s essential to keep fluids clean.
   
2. Track Maintenance: Inspect the tracks and undercarriage regularly for wear. Adjust track tension as necessary, and replace any worn parts to prevent issues from escalating.
   
3. Routine Inspection: Check for any signs of leaks, wear, or damage, particularly around the hydraulics, tracks, and engine. Early detection of problems will help avoid costly repairs down the road.
   
4. Air and Fuel Filters: Change the air and fuel filters regularly to prevent clogging and ensure the engine operates at peak efficiency.
   

Conclusion
The IHI 35N is a versatile, reliable mini-excavator well-suited for a range of construction tasks. Its compact size, powerful hydraulic system, and strong lifting capacity make it a valuable tool in confined spaces and for lighter-duty jobs. However, like any piece of equipment, the 35N requires regular maintenance to ensure optimal performance.
By addressing common issues such as hydraulic performance, track wear, and engine care, operators can extend the lifespan of the machine and maintain its efficiency. The IHI 35N’s adaptability to various attachments and work environments, combined with its robust design, makes it a solid choice for professionals looking for a dependable and compact excavator for their operations.
