5. Maintenance
5.1 General Care
- After each use, clean the car to remove dirt, dust, and debris. Use a soft brush or cloth.
- Avoid exposing the car to extreme temperatures or direct sunlight for prolonged periods.
- Store the car in a dry, cool place.
5.2 Battery Care
- Always disconnect the battery from the car when not in use.
- Store LiPo batteries in a fire-safe bag or container.
- Do not overcharge or over-discharge LiPo batteries.
- If the battery swells, discontinue use immediately and dispose of it safely.
5.3 Component Inspection
Regularly inspect the following components for wear or damage:
- Tires: Check for cuts, cracks, or excessive wear.
- Shock Absorbers: Ensure metal oil shock absorbers and spring travel adjustable aluminum ring shock absorbers are functioning smoothly.
- Gears: Inspect powder metallurgy metal gears and the central sealed differential for wear.
- Bearings: The full vehicle uses ball bearings; ensure they are clean and free-spinning.
- Steering Servo: Check the 3.35KG metal servo for proper response and movement.
- Chassis: Inspect the aluminum alloy bottom plate and PC material body for damage.
- Transmission Components: Verify all metal transmission components are intact and secure.
- Anti-Roll Bars: Ensure front and rear anti-roll bars are not bent or broken.
6. Troubleshooting
- Car not responding: Ensure both the car and transmitter are powered on and batteries are charged. Re-pair if necessary.
- Loss of control/short range: Check transmitter batteries. Ensure no strong interference sources are nearby.
- Car drives crooked: Use the direction fine-tuning correction on the transmitter to adjust the steering trim.
- Low power/slow speed: Recharge the car battery. Check for any obstructions in the drivetrain.
- Anti-stuck protection: If the car gets stuck, the system may engage anti-stuck protection. Clear the obstruction and resume operation.
- Low voltage protection: The car will automatically reduce power or stop when the battery voltage is too low to prevent damage. Recharge the battery.
