Preventive Maintenance
Chain Tension Adjustment
The chain on your bike has been factory set and lubricated. It should not require adjustment initially. Over time, however, you may
need to adjust the tension.
CAUTION: Improper chain adjustment will cause premature wear and may void the warranty.
To adjust chain on eSpinner
1. Using a 3mm Allen Wrench, remove the four screws supporting the
plastic chain guard shroud. (Figures 1)
2. Using a 16mm or 5/8" socket and socket wrench, loosen the axle
nuts on both sides of the flywheel.
3. Using a 10mm open end wrench, loosen the lock nuts on the chain
adjustment screws.
4. To tighten the chain, turn the adjustment screw in a clockwise rota-
tion equally on both sides using the 10mm open end wrench.
5. To loosen the chain, turn the adjustment screws on both sides
counter-clockwise using a 10mm open end wrench.
6. While adjusting the chain tension, work on both sides of the fly-
wheel. Adjust the angle of the flywheel so it is straight front to rear
and evenly spaced within the frame side to side. (Figure 2 )
7. Align the chain so it runs straight on both of the sprockets.
8. Adjust the angle of the flywheel by adjusting the adjustment screws
on both sides of the flywheel. Test by slowly rotating the pedals.
Note:
•
If the chain is stretched beyond adjustment, the replace-
ment of the chain is recommended. Proceed to "Chain
Replacement" for further instructions.
•
When alignment is at the optimal adjustment, the chain will
run smoother and quieter.
9. Tighten the adjustment lock nuts and axle nuts on both sides.
10. Install the chain guard shroud and re-test the bike.
