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 left pedal
arm, the left pedal disc, and the left shield.
First, see steps 14 and 15 on page 12 and remove
the Left Pedal Arm (11).
See EXPLODED DRAWING A on page 22. Using a
flat screwdriver, remove the left Pedal Disc (15).
Remove all the M4 x 16mm Self-tapping Screws (52)
from the Left and Right Shields (3, 4).
Next, remove the two M6 Locknuts (66). Then, remove
the Left Shield (3).
Loosen the M8 x 22mm Flat Head Screw (65) and turn
the M10 x 60mm Bolt (62) until the Drive Belt (19) is
tight.
When the Drive Belt (19) is tight, tighten the M8 x
22mm Flat Head Screw (65).
Then, reattach the shields, the left pedal disc, and the
left pedal arm.
