• Zero-Tail Swing: The combination of zero-tail swing and arm deviation is ideal for narrow and complex working conditions. When operating near a wall, the excavator can perform direct excavation without frequent repositioning, ensuring flexible construction.
• Flat Ground Operation: Smooth flat ground operation is achieved through the collaborative use of superstructure swing, boom deviation, dozer blade rising and falling, and the long and short arms, along with the bucket and dozer blade.
• Hydraulic System: Equipped with a high-performance hydraulic system and relevant elements, the composite actions of the boom, arm, bucket, and swing motor are harmonious and smooth, providing excellent performance.

5.3. Engine and Power

The excavator is equipped with an engine that conforms to EPA4 and Stage V emission standards, delivering strong power for demanding tasks. This ensures both high performance and environmental compliance.

6. Maintenance

Regular maintenance is crucial for the longevity and optimal performance of your excavator. Refer to the detailed maintenance schedule in the full service manual for specific intervals.

6.1. Daily Checks

• Check engine oil level.
• Check hydraulic oil level.
• Inspect coolant level.
• Check fuel level and drain water from the fuel filter.
• Clean air filter if necessary.
• Inspect tracks and undercarriage for debris or damage.
• Lubricate all grease points.

6.2. Refilling Capacities & Lubrications

Note: Always use fluids and lubricants recommended by the manufacturer.
