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 right
pedal, the shield cover, and the right shield (see the
instructions below).
Using an adjustable wrench, turn the right pedal coun-
terclockwise and remove it.
See the HOW TO ADJUST THE REED SWITCH on
page 18 and remove the Shield Cover (12).
Next, see the EXPLODED DRAWING near the end of
this manual and remove the M4 x 16mm Screws (56)
from the Right and Left Shields (38, 39). Then, using a
flat screwdriver to release the tabs and the V-clip (27),
gently remove the Right Shield.
Hold the two M8 Locknuts (57) and loosen the two
M8 x 22mm Flat Head Screws (34). Next, loosen the
M10 x 35mm Hex Screw (30) until the Drive Belt (23) is
tight. Then, hold the M8 Locknuts and tighten the M8 x
22mm Flat Head Screws.
Then, reattach the right shield, the top shield, and the
right pedal.
