Setup
- Unpacking: Carefully remove all components from the packaging. Inspect for any damage during transit.
- Battery Installation: Connect the included battery to the tractor's ESC. Ensure the connection is secure. Refer to the battery and ESC manuals for specific connection details if needed.
- Radio System Setup:
- Install batteries into the Frsky XE Lite Radio System (remote control).
- Power on the remote control, then power on the tractor. The remote control and tractor should automatically bind. If not, refer to the Frsky XE Lite manual for binding instructions.
- Hydraulic Oil (Not Included): Fill the hydraulic system with appropriate hydraulic oil (not included). Consult the specific hydraulic system instructions for the correct type and filling procedure.
- Initial Checks: Before first use, verify that all moving parts operate freely and that all connections are secure. Test steering, throttle, and hydraulic functions at a low speed in a clear area.

Operating Instructions
- Power On: Turn on the remote control first, then the tractor.
- Driving: Use the joystick on the remote control to control forward/backward movement and steering. Start with slow movements to familiarize yourself with the controls.
- Hydraulic Functions: Utilize the designated channels on your Frsky XE Lite radio system to operate the front and rear hydraulic lifting hooks. Refer to your radio system's manual for channel assignments.
- Lights and Sound: Activate the light and sound systems using the corresponding switches or channels on your remote control.
- Attachments: If using compatible LESU trailers or other attachments, ensure they are securely connected to the tractor's hitch points and hydraulic lines (if applicable).
- Power Off: Always turn off the tractor first, then the remote control, to prevent unintended movements.


Maintenance
- Cleaning: After each use, clean the tractor to remove dirt, dust, and debris. Use a soft brush or cloth. Avoid using water directly on electronic components.
- Lubrication: Periodically lubricate moving parts, such as linkages and gears, with appropriate RC-grade lubricant.
- Hydraulic System: Regularly check hydraulic fluid levels and inspect for leaks. Replenish hydraulic oil as needed.
- Battery Care: Store batteries in a cool, dry place. Follow battery manufacturer guidelines for charging and storage to maximize lifespan.
- Inspection: Routinely inspect all screws, nuts, and connections to ensure they are tight. Check for any signs of wear or damage on tires, suspension, and body.
