Troubleshooting
This section addresses common issues you might encounter with your Mould King 17073 crane model.
- Missing or Incorrect Parts: If you discover missing pieces or incorrect motor types during assembly, please contact customer support immediately. Do not attempt to force incompatible parts.
- Structural Instability (Frame Sagging): Ensure all connecting pins and blocks are firmly seated according to the instructions. Re-examine the frame assembly for any misaligned or improperly connected sections.
- Sloppy or Grinding Gears: This can indicate incorrect assembly, misaligned gears, or debris. Disassemble the affected section, clean the gears, and reassemble carefully, ensuring all gears mesh correctly without excessive friction.
- Steering Issues: If steering racks do not stay in place or the vehicle does not steer correctly, verify the assembly of the steering mechanism. Ensure all components are securely attached and move freely without binding.
- Telescoping Boom Malfunctions: If the boom gets stuck, breaks gears, or leans excessively, re-examine the internal mechanism of the boom. Ensure all parts are correctly aligned and that the lifting cord (if applicable) is properly routed and tensioned.
- Outrigger Problems: If outriggers grind or pop, check their assembly for correct gear engagement and smooth movement. Ensure no parts are obstructing their extension or retraction.
- Remote Control/App Connectivity Issues: Ensure the model's battery is charged and the model is powered on. Re-pair the remote control or re-establish the Bluetooth connection via the app. If specific functions are activated by the wrong channel, consult the app's control mapping or the remote control's instructions for recalibration.
If troubleshooting steps do not resolve the issue, please refer to the Support section for further assistance.
