We recommend you have at least 78.7" of clearance directly behind the Tread and 20” of clearance in front and on both the right and lefts sides of the Tread.
The provided power cord must also be able to reach the outlet at both the minimum and the maximum inclines.
The back feet of the Tread are adjustable. If the Tread rocks or wobbles, turn one or both of the back feet clockwise until all feet rest firmly on the ground.
Lastly, the power cord must never pass under the Tread.
