Workability
The zero-tail swing design of the mini-excavator allows operators to work efficiently without concern for the rear of the machine. The machine's width can be adjusted to pass through narrow pathways (AX10u: 780mm, AX17u: 980mm) and extended during operation for stability (AX10u: 1000mm, AX17u: 1280mm). The crawler can be adjusted according to the situation.

Safety
Safety features include a lock lever to secure the boom, swing, and travel operations, preventing improper use. The engine can only start in neutral with the lock lever engaged.

Serviceability
Front hoses are stored within the arm to prevent damage, and articulated hoses are used for easy replacement. The engine cover is fully openable for maintenance access.

Operability
The hydraulic pilot system ensures smooth and light operation. The AIRMAN series mini-excavators, AX10u-4/AX17u-4, offer enhanced serviceability and safety, alongside basic functions like digging, loading, and leveling.
