HOW TO ADJUST THE DRIVE BELT
If the pedals slip while you are pedaling, even while the
resistance is adjusted to the highest setting, the drive
belt may need to be adjusted.
To adjust the drive belt, first unplug the power adapter.
Then, you must remove the top shield, the right pedal,
and the right shield (see the instructions below).
Using a flat screw-
driver, release the
tabs at the front
and along the
sides of the Top
Shield (44). Then,
slide the Top
Shield upward.
Next, using an adjustable wrench, turn the right pedal
counterclockwise and remove it. Then, remove the
screws from the right and left shields, and gently
remove the right shield.

Next, loosen the M6 x 20mm Hex Screw (84). Then,
tighten the M10 x 50mm Hex Screw (83) until the Drive
Belt (47) is tight. When the Drive Belt is tight, tighten
the M6 x 20mm Hex Screw.
When the Drive Belt (47) is correctly adjusted, reattach
the right shield, the right pedal, and the top shield and
then plug in the power adapter.
