3. Assembly Instructions

Unpacking and Placement
- Carefully remove all components from the packaging.
- Place the treadmill in its desired location, ensuring a stable and level surface.
Console Attachment
When attaching the console to the uprights, it may be easier to leave the bottom bolts slightly loose initially. This allows for better alignment before tightening all fasteners securely. If there is a tight fit between the fixing bracket, plastic, and upright, gently loosen the console screw inside to facilitate sliding past.

- Speed Display in KM/H Only: The treadmill displays speed exclusively in kilometers per hour (KM/H) and does not offer a miles per hour (MPH) option.
