HOW TO ADJUST THE DRIVE BELT
If you can feel the pedals slip while you are pedaling,
even when the resistance is at the highest level, the
drive belt may need to be adjusted.
To adjust the drive belt, you must first remove the right
pedal and the right shield as described below.
Using an adjustable wrench, turn the right pedal coun-
terclockwise and remove it. Next, remove all of the
screws from the left and right shields; there are two
sizes of screws in the shields——note which size of
screw you remove from each hole. Then, gently pull
the right shield away from the frame.
Next, loosen the M6 x 20mm Hex Screw (31). Then,
tighten the M10 x 50mm Hex Screw (66) until the Drive
Belt (35) is tight.
When the Drive Belt (35) is tight, tighten the M6 x
20mm Hex Screw (31).
Then, reattach the right shield and the right pedal.
