Your treadmill features a walking belt coated with PERFORMANT LUBETM, a high-performance lubricant.

IMPORTANT: Never apply silicone spray or other substances to the walking belt or the walking platform. Such substances will deteriorate the walking belt and cause excessive wear.


DANGER: Improper connection of the equipment-grounding conductor can result in an increased risk of electric shock. Check with a qualified electrician or serviceman if you are in doubt as to whether the product is properly grounded. Do not modify the plug provided with the product—if it will not fit the outlet, have a proper outlet installed by a qualified electrician.

Your treadmill, like any other type of sophisticated electronic equipment, can be seriously damaged by sudden voltage changes in your home’s power. Voltage surges, spikes, and noise interference can result from weather conditions or from other appliances being turned on or off. To decrease the possibility of your treadmill being damaged, always use a surge suppressor with your treadmill (see drawing 1 at the right). To purchase a surge suppressor, see your local NordicTrack dealer or call 1-888-936- 4266 and order part number 146148.

Use only a single-outlet surge suppressor that is CUL 1449 listed as a transient voltage surge suppressor (TVSS). The surge suppressor must have a UL suppressed voltage rating of 400 volts or less and a minimum surge dissipation of 450 joules. The surge suppressor must be electrically rated for 120 volts AC and 15 amps. There must be a monitoring light on the surge suppressor to indicate whether it is functioning properly. Failure to use a properly functioning surge suppressor could result in damage to the control system of the treadmill. If the control system is damaged, the walking belt may change speed or stop unexpectedly, which may result in a fall and serious injury.

This product must be grounded. If it should malfunction or break down, grounding provides a path of least resistance for electric current to reduce the risk of electric shock. This product is equipped with a cord having

an equipment-grounding conductor and a grounding plug. Plug the power cord into a surge suppressor, and plug the surge suppressor into an appropriate outlet that is properly installed and grounded in accordance with all local codes and ordinances. Important: The treadmill is not compatible with GFCI-equipped outlets.

This product is for use on a nominal 120-volt circuit, and has a grounding plug that looks like the plug illustrated in drawing 1 below. A temporary adapter that looks like the adapter illustrated in drawing 2 may be used to connect the surge suppressor to a 2-pole receptacle as shown in drawing 2 if a properly grounded outlet is not available.

The temporary adapter should be used only until a properly grounded outlet (drawing 1) can be installed by a qualified electrician.

The green-colored rigid ear, lug, or the like extending from the adapter must be connected to a permanent ground such as a properly grounded outlet box cover. Whenever the adapter is used it must be held in place by a metal screw. Some 2-pole receptacle outlet box covers are not grounded. Contact a qualified electrician to determine if the outlet box cover is grounded before using an adapter.

The advanced console offers an impressive array of features designed to help you get the most from your exercise. When the manual mode is selected, the speed and incline of the treadmill can be changed with the touch of a button. As you exercise, the console will provide continuous exercise feedback. You can even measure your heart rate using the built-in handgrip pulse sensor. Note: For information about an optional chest pulse sensor, see page 26.

The console also offers six preset workout programs. Each program automatically controls the speed and incline of the treadmill to give you an effective workout. You can even create your own custom workout programs and store them in memory for future use.

In addition, the console offers two heart rate programs that automatically adjust the speed and incline of the treadmill to keep your heart rate near a target level while you exercise. Note: The heart rate programs require the use of the optional chest pulse sensor.

The console also features new interactive technology. Having technology is like having a

personal trainer in your home. Using the included audio cable, you can connect the treadmill to your home stereo, portable stereo, computer, or VCR and play special CD and video programs ( CDs and videocassettes are available separately). CD and video programs automatically control the speed and incline of the treadmill as a personal trainer coaches you through every step of your workout. High-energy music provides added motivation. To purchase CDs or videocassettes, call tollfree 1-888-936-4266.

With the treadmill connected to your computer, you can also go to our Web site at and access programs directly from the internet. Additional options are soon to be available. See for more information.

To use the manual mode of the console, follow the steps beginning on page 12. To use a preset program, see page 14. To create and use a custom program, see pages 16 and 17. To use a heart rate program, see page 18. To use an CD or video program, see page 22. To use an program directly from our Web site, see page 24.


CAUTION: Before operating the console, read the following precautions.

Do not stand on the walking belt when turning on the power.

Always wear the clip (see the drawing on page 11) while operating the treadmill.
