If your self-propelled item is not moving despite the motor humming and the axle spinning, a possible cause for this issue could be missing keys from the wheels. The keys play a crucial role in transmitting power from the axle to the wheels, allowing for movement. If the keys are missing or damaged, the power transfer may be disrupted, resulting in no movement.
To resolve this problem, follow these steps:
1. Locate the wheel keys: Consult the owner's manual or examine the wheels to locate the keyways and check if the keys are missing.
2. Obtain replacement keys: Contact the manufacturer or a local authorized dealer to acquire replacement keys specifically designed for your self-propelled item. Provide them with the make, model, and serial number of your equipment to ensure you get the correct keys.
3. Install the replacement keys: Once you have the replacement keys, insert them into the keyways on the axle and align them with the keyways on the wheels. Ensure they fit securely and engage properly.
4. Test the self-propelled function: After installing the replacement keys, test the self-propelled feature by engaging it and checking if the item moves correctly. If the motor hums, the axle spins, and the wheels now have proper traction, the issue should be resolved.
If the problem persists even after replacing the keys, it is recommended to consult a qualified technician or the manufacturer's customer support for further assistance.
