2. Setup Instructions
Before operating your LESU LR960 hydraulic excavator, please follow these setup steps carefully.
2.1 Unpacking and Inspection
- Carefully remove all components from the packaging.
- Inspect the excavator for any visible damage during transit. Contact customer support immediately if any damage is found.
- Verify all included items are present: 1/14 RC Hydraulic Excavator Model, Metal Rack of Arm, ESC, Motor, Servo, Light System, Hydraulic Motor Driving Wheel, Hydraulic System with 13-ways Directional Valve, Integrated Pump, Manual Quick Release Coupler, Rotating Warning Lights, Metal GPS, Frsky XE Customized Remote Controller and Receiver, Battery.
2.2 Battery Installation and Charging
- Locate the battery compartment on the excavator.
- Connect the provided battery to the excavator's power connector.
- Note: A charger is not included with this model. Please use a compatible charger for the provided battery type (e.g., LiPo charger). Ensure the battery is fully charged before first use.
- Securely close the battery compartment.
2.3 Remote Controller Setup
- Install appropriate batteries (not included) into the Frsky XE Customized Remote Controller.
- Power on the remote controller.
- Refer to the Frsky XE remote controller manual for specific binding procedures if the excavator and controller are not already paired.
2.4 Hydraulic Oil Filling
- Note: Hydraulic oil is not included with this model. Use only recommended hydraulic oil for RC models.
- Locate the hydraulic oil reservoir, identifiable by its visible large window and filter.
- Carefully fill the reservoir with the appropriate hydraulic oil, ensuring not to overfill. Monitor the oil level through the visible window.
- After filling, operate the hydraulic functions slowly to bleed any air from the system. Top up oil if necessary.

3. Operating Instructions
Familiarize yourself with the remote controller and the excavator's functions before operating in a real environment.
3.1 Powering On
- Ensure the remote controller is powered on first.
- Turn on the power switch on the excavator. The light system will activate.
- Wait for the remote controller and excavator to establish a connection.
3.2 Basic Controls (Frsky XE Remote Controller)
The Frsky XE remote controller provides precise control over the excavator's functions. Refer to the controller's specific manual for detailed button assignments.
- Track Movement: Typically controlled by joysticks for forward, backward, and turning movements. The adjustable-width travel frame can be controlled via a dedicated channel.
- Boom, Arm, and Bucket: Controlled by joysticks, allowing for independent movement of the main boom, stick arm, and bucket. The 13-way directional valve enables complex hydraulic movements.
- Turntable Rotation: A dedicated control allows for 360° continuous rotation of the excavator's upper structure.
- Hydraulic Crusher/Attachments: If equipped, the hydraulic crusher or other attachments are controlled via specific channels on the remote. The quick-release coupler allows for easy attachment changes.
- Lights and Warning Lights: Operated via switches or buttons on the remote controller.
- Cab Lift: The hydraulically powered lifting cab can be raised or lowered via a designated control.
3.3 Operating Tips
- Start with slow, deliberate movements to get accustomed to the controls.
- Avoid sudden or jerky movements, especially with hydraulic functions, to prevent damage and ensure smooth operation.
- Monitor the electronic display screen in the cab for real-time information on electrical components.
- When switching attachments, ensure the excavator is powered off and the hydraulic system is depressurized.

4. Maintenance
Regular maintenance ensures the longevity and optimal performance of your LESU LR960 excavator.
4.1 General Cleaning
- After each use, clean the excavator to remove dirt, dust, and debris. Use a soft brush or compressed air.
- Avoid using water directly on electronic components. If cleaning with a damp cloth, ensure all parts are dry before storage or next use.
4.2 Hydraulic System Maintenance

- Inspect for Leaks: Periodically check all hydraulic lines, cylinders, and connections for any signs of leaks. Address leaks promptly to prevent system damage.
- Filter Inspection: Inspect the hydraulic oil filter for contamination. Replace if necessary.
4.3 Track and Undercarriage
- Clean debris from the tracks and undercarriage regularly to prevent binding and wear.
- Inspect track links and drive sprockets for wear or damage.
4.4 Battery Care
- Always disconnect the battery from the excavator when not in use.
- Store batteries in a cool, dry place, away from direct sunlight and extreme temperatures.
- Follow the manufacturer's guidelines for charging and discharging LiPo batteries.
