NordicTrack is a manufacturer of home fitness equipment. The company began by selling indoor cross-country ski machines, then expanded into other types of fitness equipment in the 1990s. The NordicTrack 990 elliptical features an adjustable ramp, pedal resistance and heart rate monitor that can all be controlled from main console of the machine. The elliptical needs to be monitored closely before and after use for any issues that may arise. Troubleshoot the elliptical immediately or contact NordicTrack for repairs.
Clean the heart rate monitoring pads if the console is not displaying your heart rate when you grip the pads. Use a damp cloth and a mild soap to clean the pads. Do not use alcohol or any other abrasive cleaners that may damage the equipment.
Calibrate the ramp if the elliptical is not functioning properly. Press and hold the "Target Toning Workouts" button on the console until the calibration mode appears on the display. Press the "Target Toning Workouts" button once. The elliptical will display additional directions. Use the "One Step Power Ramp" increase and decrease buttons to raise and lower the ramp.
Adjust the reed switch by removing the access cover, which sits over the wheel of the elliptical at the back of the machine. The access cover can be removed with a flat-head screwdriver. Unplug the machine. The reed switch provides information to the console for display. Rotate the pulley until the pulley magnet, which is under the belt, lines up with the reed switch. The reed switch has a wire running into it. Loosen the screw to the reed switch and adjust the distance closer or farther from the pulley magnet. Tighten the screw. Plug in the machine and rotate the pulley. If the console still is not displaying correctly, repeat adjusting the reed switch distance either closer or father from the pulley magnet.
Adjust the drive belt if the pedals slip while in use. Unplug the elliptical. Lift the latch on the underside of the left pedal arm and slip it off. Use a screwdriver to remove the arm sleeve and pry open the disc panel. Loosen the pivot screw located on the left side. The belt tighten screw is below the pivot screw. Tighten the belt tightening screw until the belt is tight. Tighten the pivot screw. Replace the disc and arm to the elliptical.
