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, see EXPLODED DRAWING A
on page 26. Remove the M4 x 16mm Screws (47)
and the M4 x 25mm Screws (41) from the Left and
Right Shields (17, 18). Make sure to note which size
of Screw you remove from each hole. Then, gently
move the Left Shield out of the way.
Note: For clarity, the left shield is shown removed in
the drawing at the right.
Loosen the M6 x 20mm Hex Screw (46). Then, tighten
the M10 x 50mm Hex Screw (66) until the Drive Belt
(35) is tight.
