15. Level the unit. Diagram 13. The M9.31 has adjustable rear feet. Check to make
sure that the running surface is level (use a bubble level as shown in Diagram 13).
If the treadmill is placed on a slightly, uneven surface, adjusting the rear feet can
help, but will not compensate for extremely uneven surfaces.
Important: If you need to make adjustments, adjust one rear foot at a time. Do
not use the rear foot to raise or lower the unit more than ¾-inches. Check the
level of the unit after each adjustment.
16. Adjust the rear deck. Diagram 13, #3. To raise the rear deck, insert the ¼-inch
hex key (G). Make sure that the key is fully engaged and turn it clockwise.
Turning the hex key counterclockwise lowers the unit.
Connect the power
cord and turn on the
treadmill.
