TROUBLESHOOTING
SYSTEMATIC MECHANICAL TROUBLESHOOTING
If you hear a grinding or clicking noise or experience excessive vibration during
exercise, a problem exists in the drive train of your machine. Isolate the problem
area by performing the following tests in precisely the order listed below. Refer
to the appropriate “Parts Removal and Replacement” section of this manual for
all disassembly and assembly instructions.
1. Remove the base and side covers.
2. Remove the upper and lower Poly-V belts, and inspect the belts for
cracks and/or fraying. A worn belt could cause the loss of resistance -
replace if necessary.
3. Verify that the brake is off, and spin the alternator pulley. The pulley
should spin freely four to five revolutions without any clicking or
grinding noises. Replace the alternator if any noises within the
alternator are heard.
4. Spin the intermediate and lower Poly-V pulleys. The pulleys should
spin freely without any clicking or grinding. Replace the pulley(s) if any
noises are heard.
5. Inspect the step chains, heel link chains, and the drive chain
assemblies for frozen links and/or corrosion. Pay particular attention to
areas of high wear. For example, the section of chain that contacts the
sprockets during operation. Replace a chain if any problems are found.
6. Inspect the pedal return springs for corrosion. Clean corrosion off the
springs with fine steel wool. Replace the springs if the metal is pitted.
TO REDUCE THE RISK OF INJURY, DO NOT OPERATE THE
MACHINE WHILE THE COVERS ARE REMOVED. DO NOT MOVE THE
PEDALS WHILE ANYONE’S HANDS ARE INSIDE THE MACHINE.
