Basic Troubleshooting Problem: Loud Squealing Sound From the Brake Figure 1 Solution: A. Use a 4mm Allen wrench to remove the bolt and spring from the brake assembly. (See Figure 1.) B. Slide the brake pads out of the assembly. C. Rough up the surface with a wire brush if the pads look glossy. D. Saturate the brake pads with silicone lubricant after they have been roughed up. E. Replace the brake pads. F. Tighten the bolt and spring to the pads only finger-tight.
Basic Troubleshooting Problem: Brake Pads Off Center Figure 3 Solution: A. Use a 10mm wrench to loosen the nylon nut on the front of the bike. B. Adjust the brake assembly until the brake pads are evenly spaced from the flywheel. C. Tighten the nylon nut using moderate torque. Problem: Chain is too Loose Figure 4 Solution: A. Use a 15mm wrench or socket to loosen each axle nut of the flywheel. B. Use a 10mm wrench and turn each chain tensioner bolt 1/4 turn to the right. C.
Basic Troubleshooting Problem: Chain Makes a Grinding Sound Solution: Chain too tight and/or the flywheel out of alignment. A. Use a 15mm wrench to loosen each axle nut. B. Adjust the 10mm chain tensioner bolts to align the flywheel with the frame. Make sure that the chain tensionis adjusted properly without being too tight. C. Adjust the chain tension by locating the point where the chain is tightest during one revolution of the crank. D. Check the tension.

Preventative Maintenance Attention: Any Schwinn® bike that is allowed to operate with torque in excess of the specified values does not qualify for warranty replacement for the crank arms. Do NOT torque crank bolts in excess of 360 obf/in. on IC Pro and IC Elite or 420 lbf/in on Evolution models. Overtightening causees damage to the crank or the bottom bracket interface. Daily Maintenance At the end of each workout: • Release the brake resistance so that the brake pads do not contact the flywheel.
Preventative Maintenance Adjust the Smart Release™ Mechanism Tools: • Smart Release™ Adjusting tool • 45 to 50 lb. dumbell or weight Figure 11 Attention: Only a mechanic trained to work on Schwinn® IC bicycles should do this procedure. Make adjustments to the Smart Release™ mechanism only to restore the mechanism to factory specifications. Never overtighten. Smart Release™ Adjusting Plate Procedure: 1. Ride the bike. This forces the the Smart Release™ mechanism to break free.
