Noise Issues - Squeaking, Squealing, Creaking or Chirping

BEGIN HERE

Remove the rubber end cap, where the pedal arm connects to the crank arm, on both sides of the machine.

Does the noise

persist?

YES

Apply a small drop of silicone based lubricant on the rails, and then wipe the rails with a dry towel. If too much lubricant is applied then the roller wheel may not roll. Pedal the machine slowly to ensure that the roller wheels are turning freely.

Does the noise

persist?

YES

NO

Re-attach the end caps

loosely. If they are

pushed on too tight, they

will make squeaking

noises.

Issue resolved.

Go to Troubleshoot-

ing: Roller and Pedal

Apply a drop of mineral oil to the bushings on each side of the roller wheel (No need to disassemble) one side at a time.

Do NOT apply lubricant directly to the wheel. Catch any excess lubricant with a towel or cloth.

Test for noise on each side.

Contact Heart Rate Issues

BEGIN HERE

Ensure hands are centered on the Heart Rate (HR) sensors with equal pressure, and as little movement as possible without touching the metal frame.

Explain that the HR may spike

initially at a high rate, when ﬁrst

touching the contact plates. This is normal, and it will normalize out after waiting a couple of minutes. Try not to move the hands while waiting. If a quicker HR reading is required, switch to a Bluetooth HR Strap.

®

Dry or heavily calloused hands may need a heart rate cream to make better contact. Search for Buh-Bump Heart Rate Cream online.

Issue resolved. Replace the Console

NO

Does the issue

persist?

Upper (Drive) Pulley

Begin by inspecting around the machine for any hardware that may have fallen out of the machine. Next remove the rear shroud, and inspect the upper, or drive, pulley. A flashlight may be needed.

Note the pulley screws, which can be seen protruding from the back of the pulley. By manipulating the foot pedals the pulley will rotate, allowing the ability to check all four screws.

* Note whether all four screws are in place. * Note whether all screws stick out about the same distance. * Check that the belt is in place, and is not visibly damaged. * Attempt to wiggle the pulley towards and away from the mast. * Observe whether the pulley wobbles as it rotates.

After inspection, proceed with the troubleshooting steps in order.

Crank Puller: A Crank Puller is required to replace the drive pulley.

Has the Upper Pulley

already been replaced

recently?

Is the drive belt

in place around the

pulley?
