HOW TO ADJUST THE DRIVE BELT

even when the resistance is adjusted to the highest
level, the drive belt may need to be adjusted.
To adjust the drive belt, first remove the M4 x 19mm
Self-tapping Screw (100) from the Side Access Cover
(21), and then remove the Side Access Cover by
moving it in the direction shown by the arrow.
