HOW TO ADJUST THE DRIVE BELT
If you can feel the pedals slip while you are pedaling,
even when the resistance is adjusted to the highest
level, the drive belt may need to be adjusted.
To adjust the drive belt, you must remove the top shield
and the left shield (see the instructions below).
Using a flat screwdriver, release the tabs on the front
and rear of the Top Shield (20), and then remove the
Top Shield.

Next, remove the M4 x 16mm Round Head Screws
(90) and the M4 x 42mm Screws (98) from the Right
and Left Shields (18, 19). Make sure to note which
size of Screw you remove from each hole. Then,
gently remove the Left Shield.
Loosen the Pivot Screw (97). Then, tighten the Belt
Adjustment Screw (85) until the Drive Belt (38) is tight.
When the Drive Belt (38) is tight, tighten the Pivot
Screw (97).
Then, reattach the left shield and the top shield.
