Operating Modes
The Goplus 2-in-1 Folding Treadmill offers two distinct operating modes:

2. Walking Mode (Handrail Folded)
- When the handrail is folded down, the treadmill functions as an under-desk walking machine.
- The maximum speed in walking mode is 2.5 MPH.
- This mode is ideal for light exercise while working or engaging in other activities.

Maintenance
Lubrication
- The running belt requires periodic lubrication with special methyl silicone oil.
- Frequency of lubrication depends on usage:
- 1 hour or less per week: Lubricate once every 6 months.
- Less than 3 hours per week: Lubricate once every 3 months.
- 3-6 hours per week: Lubricate once every 2 months.
- More than 6 hours per week: Lubricate once a month.
- Do not over-lubricate. More lubricant is not necessarily better.
- Proper lubrication is crucial for extending the lifespan of the treadmill.
Running Belt Adjustment
- Over time, the running belt may deviate to the left or right due to consistent use.
- To correct this, use the provided hex driver to adjust the screws at the rear of the treadmill.
- Turn the screw clockwise or counter-clockwise based on the direction the belt needs to be adjusted. Refer to the manual's diagrams for specific instructions.
