Operating Instructions
The Aoue 9150 features a precise hydraulic system for coordinated and smooth movements. Familiarize yourself with the controls before operating in challenging environments.
Basic Controls:
- Movement: Use the left joystick (or corresponding controls) for forward, backward, and turning movements of the tracks.
- Arm and Bucket: The right joystick and additional switches control the main arm, secondary arm, and bucket movements. Practice these movements to achieve fluid operation.
- Hydraulic System: The double oil pump hydraulic system provides super large flow for powerful digging and lifting. Operate controls smoothly to avoid sudden movements.
Advanced Features:
- Lighting System: The full machine lighting system can be activated via a dedicated switch on the remote controller.
- Analog Electronic Display: Monitor real-time operational data such as voltage, temperature, and current on the integrated display.
- Modular Design: The modular design allows for the arm to be replaced with a forward shovel (sold separately) for different operational needs.

Maintenance
Regular maintenance ensures the longevity and optimal performance of your excavator.
- Cleaning: After each use, clean the excavator to remove dirt, dust, and debris. Pay special attention to the tracks, hydraulic cylinders, and moving parts. Use a soft brush and compressed air.
- Hydraulic System Check: Regularly inspect hydraulic lines and cylinders for leaks or damage. Ensure all connections are secure. The oil circuit system is largely welded with copper for reliability.
- Track Inspection: Check the metal tracks for wear, damage, or debris lodged between links. Ensure smooth movement.
- Battery Care: Store batteries in a cool, dry place. Follow manufacturer guidelines for charging and discharging to prolong battery life.
- General Inspection: Periodically check all screws, bolts, and moving parts for tightness and proper function.
