4. Use a 15 mm crescent wrench to hold the Axle Nut (B) on one
side steady and loosen the Axle Nut on the opposite side with a 15
mm socket and wrench.
Be sure to keep fingers clear of all pinch hazards.
5. Check the tension:
Find the point where the Drive Chain (A) is tightest during one
revolution of the Crank (C). You should be able to move the chain up
and down about 3/8" (in either direction).
If the Drive Chain is too loose—use a 10mm wrench to turn each
Flywheel Retainer bolt (D) 1/4 turn to the right.
If the Drive Chain is too tight—use a 10mm wrench to adjust the
Flywheel Retainer bolts (D).
6. Reinstall the right Pedal. Carefully align the threads and hand
tighten to prevent crossthreading. Then tighten fully with pedal
wrench.
7. Get on the bike and check the movement of the Drive Chain (A)
by rocking back and forth on the pedals. The Pedals and Flywheel
(E) should move as one.
Adjust the Drive Chain tension again if necessary.
8. Tighten the Axle Nuts (B) when the Drive Chain tension is
correct.
NOTICE: Make sure the Flywheel (E) is aligned with the Frame.
Be sure the Flywheel axle does not touch the Chain
Guard Inside.
9. Remove the right Pedal. Reinstall the Chain Guard Cover, Chain
Guard Center and Pedal.
10. Final Inspection
