Chain Adjustment
Maintenance
The chain must be at the correct tightness. If too tight, the
bicycle will be difficult to pedal. If too loose, the chain can
come off the sprockets.
WARNING:
The chain must remain on the
sprockets. If the chain comes off the sprockets,
the coaster brake will not operate.
When the chain [1] is at the correct tightness, you can pull
it one-half inch [2] away from a straightedge [3] as shown.
Adjust the tightness of the chain as follows:
- Loosen the axle nuts [4] of the rear wheel
- Loosen the clamp [5] on the brake arm [6], but do not
remove the nut and the screw from the clamp
NOTE:
Make sure the rear wheel is in the center of the
bicycle frame.
- Move the rear wheel forward or backward as necessary, until you can pull the chain one-half inch
away from a straightedge
- Hold the wheel in this position and tighten the axle nuts to the recommended torque of 14 ft.-lbs.
- Tighten the brake arm clamp.
Tires
Maintenance
Frequently check the tire inflation pressure because all tires lose air slowly over time. For extended
storage, keep the weight of the bicycle off the tires.
WARNING:
Do not ride or sit on the bicycle if either inner tube is under inflated. This can
damage the tire and inner tube. Do not use unregulated air hoses to inflate the inner tubes.
An unregulated hose can suddenly over inflate bicycle tires and cause them to burst.
Use a hand or a foot pump to inflate the inner tubes. Service station meter-regulated air hoses are
also acceptable. The correct inflation pressure is shown on the tire sidewall.
Before adding air to any tire, make sure the edge of the tire (the bead) is the same distance from the
rim, all around the rim, on both sides of the tire. If the tire does not appear to be seated correctly,
release air from the inner tube until you can push the bead of the tire into the rim where necessary.
Add air slowly and stop frequently to check the tire seating and the pressure, until you reach the
correct inflation pressure as indicated on the tire sidewall.
Replace worn or defective tires and inner tubes.
