5. Maintenance

5.1. General Cleaning

After each use, especially when operating in dusty or dirty environments, clean the excavator thoroughly. Use a soft brush or compressed air to remove debris from moving parts, wheels, and the chassis. Avoid using water directly on electronic components.

5.2. Hydraulic System Check

Regularly check the hydraulic oil level in the integrated tank. Top up with appropriate hydraulic oil as needed. Inspect hydraulic lines and cylinders for any leaks or damage. Ensure all connections are tight.

5.3. Battery Care

Always disconnect the battery from the excavator when not in use. Store batteries in a cool, dry place. Do not overcharge or completely discharge the battery, as this can reduce its lifespan. If the model will not be used for an extended period, store the battery at approximately 50% charge.

5.4. Lubrication

Periodically apply a small amount of appropriate lubricant to moving joints and pivot points to ensure smooth operation and prevent wear.

6. Troubleshooting

6.1. Model Not Responding

• Ensure both the remote controller and excavator are powered on.
• Check battery levels in both the excavator and the remote controller. Replace or recharge as necessary.
• Verify that the remote controller and receiver are properly bound. Refer to the remote controller's manual for binding procedures.

6.2. Weak Hydraulic Movement

• Check the hydraulic oil level and refill if low.
• Inspect for any air bubbles in the hydraulic system. Operate the system through its full range of motion several times to bleed air.
• Ensure the battery is fully charged, as low power can affect hydraulic performance.

6.3. Unusual Noises

• Identify the source of the noise. It could be from the motor, gears, or hydraulic pump.
• Check for any obstructions or loose parts.
• If the noise persists, discontinue use and contact customer support.
