- Power Connection: Plug the power cord into the treadmill's power input, then into a grounded electrical outlet.
- Safety Key: Attach the safety key to the designated magnetic area on the control panel. Clip the other end of the safety key to your clothing. The treadmill will not operate without the safety key in place.
6. Operating Modes
The ANCHEER 2-in-1 Treadmill offers two primary operating modes: Walking Mode (under-desk) and Running Mode (with handrail raised).

9. Maintenance
Regular maintenance ensures the longevity and optimal performance of your treadmill.
- Belt Lubrication: The running belt requires periodic lubrication to reduce friction and wear. Apply the provided lubrication oil under the belt as instructed in the separate lubrication guide (if included) or refer to the general guidelines for treadmill belt lubrication. Insufficient lubrication can lead to increased motor strain and belt issues.
- Belt Adjustment: Over time, the running belt may shift or become loose. If the belt is not centered or slips, it requires adjustment. Use the provided Allen wrench to turn the adjustment bolts at the rear of the treadmill. Turn the bolts in small increments (e.g., quarter turns) and test the belt's alignment and tension. Refer to the specific instructions in the manual for detailed belt adjustment procedures. Incorrect adjustment can damage the belt or motor.
- Cleaning: Wipe down the treadmill surfaces with a damp cloth after each use. Avoid using abrasive cleaners or solvents.
10. Troubleshooting
This section addresses common issues you might encounter with your treadmill.
- Treadmill Not Starting:
- Ensure the power cord is securely plugged into both the treadmill and a working electrical outlet.
- Verify that the safety key is correctly placed on the magnetic sensor.
- Check if the main power switch (if present) is in the 'ON' position.
- Belt Slipping or Not Centered:
- This often indicates the need for belt adjustment. Refer to the 'Belt Adjustment' section in Maintenance. Adjusting the belt requires careful, small turns of the rear bolts.
- Ensure the belt is adequately lubricated.
- Abrupt Stops During Operation:
- This can occur if the safety key is dislodged or if the power button on the remote is pressed while the treadmill is in motion. Always reduce speed before stopping to prevent sudden halts.
