3. Operating the Treadmill
Getting Started
To begin your workout, simply step onto the textured, non-slip surface of the treadmill. The non-motorized design means the belt moves as you walk or run, allowing you to control the speed and intensity of your exercise.
Adjusting Resistance
The treadmill features adjustable magnetic resistance with 8 levels. To increase or decrease the workout intensity, turn the resistance knob located on the side of the frame. Higher numbers indicate greater resistance.

Using the Electronic Monitor
The multi-function electronic monitor tracks your workout data. Use the buttons on the console to view various metrics:
- SCAN: Cycles through all functions automatically.
- TIME: Displays the duration of your workout.
- SPEED: Shows your current speed.
- DIST: Displays the distance covered during your workout.
- CAL: Estimates calories burned.
- TOTAL DIST: Shows the total accumulated distance.
- PULSE: (If applicable) Displays your heart rate.
Use the MODE button to select the desired display function, SET to configure settings, and RESET to clear current workout data.

4. Maintenance
Cleaning
Regularly wipe down the treadmill with a damp cloth to remove dust and sweat. Avoid using abrasive cleaners or solvents that could damage the finish or electronic components.
Belt Adjustment
Over time, the treadmill belt may shift to one side. This can be easily corrected by adjusting the screws at the rear of the treadmill using a small Allen wrench. Tighten or loosen the screws as needed to center the belt. Refer to the detailed instructions in your assembly manual for precise adjustment procedures.
5. Troubleshooting
Treadmill Belt Shifting
If the treadmill belt begins to shift to one side during use, it can be realigned. This is typically resolved by making minor adjustments to the rear roller bolts. Use an Allen wrench to turn the bolt on the side towards which the belt has shifted clockwise, and the opposite bolt counter-clockwise, in small increments (e.g., quarter turns). Test the belt after each adjustment until it runs centrally. Detailed instructions are available in the full product manual.
Difficulty Moving the Belt
If the belt feels unusually difficult to move even at the lowest resistance setting, ensure that the magnetic resistance knob is not set to a high intensity. If the issue persists, check for any obstructions under the belt or contact customer support.
