WARNING: To reduce the risk of burns, fire, electric shock, or injury to persons, read the following important precautions and information before operating the treadmill.

1.It is the responsibility of the owner to ensure that all users of this treadmill are adequately informed of all warnings and precautions.

2.Use the treadmill only as described in this manual.

3.Place the treadmill on a level surface, with at least 2,5 m (8 ft.) of clearance behind it and 0.5 m (2 ft.) on each side. Do not place the treadmill on a surface that blocks any air openings. To protect the floor or carpet from damage, place a mat under the treadmill.

4.Keep the treadmill indoors, away from moisture and dust. Do not put the treadmill in a garage or covered patio, or near water.

5.Do not operate the treadmill where aerosol products are used or where oxygen is being administered.

6.Keep children under the age of 12 and pets away from the treadmill at all times.

7.The treadmill should not be used by persons weighing more than 115 kg (250 lbs.).

8.Never allow more than one person on the treadmill at a time.

9.Wear appropriate exercise clothes when using the treadmill. Do not wear loose clothes that could become caught in the treadmill. Athletic support clothes are recommended for both men and women. Always wear athletic shoes. Never use the treadmill with bare feet, wearing only stockings, or in sandals.

10.When connecting the power cord (see page 9), plug the power cord into an earthed circuit. No other appliance should be on the same circuit. When replacing the fuse, an ASTA approved BS1362 type should be fitted to the fuse carrier. A 13 amp fuse should be used.

11.If an extension cord is needed, use only a 3- conductor, 1 mm2 (14-gauge) cord that is no longer than 1.5 m (5 ft.).

12.Keep the power cord and the surge suppressor away from heated surfaces.

13.Never move the walking belt whilst the power is turned off. Do not operate the treadmill if the power cord or plug is damaged, or if the treadmill is not working properly. (See BEFORE YOU BEGIN on page 5 if the treadmill is not working properly.)

14.Never start the treadmill whilst you are standing on the walking belt. Always hold the handrails whilst using the treadmill.

15.The treadmill is capable of high speeds. Adjust the speed in small increments to avoid sudden jumps in speed.

16.Using hand weights and not holding the handrails may compromise your ability to maintain your balance. Hand weights should be used only by experienced users.

17.The pulse sensors are not medical devices. Various factors, including the user's movement, may affect the accuracy of heart rate readings. The pulse sensors are intended only as exercise aids in determining heart rate trends in general.

18.Never leave the treadmill unattended whilst it is running. Always remove the key, unplug the power cord, and move the on/off switch to the off position when the treadmill is not in use. (See the drawing on page 5 for the location of the on/off switch.)

19.Do not change the incline of the treadmill by placing objects under the treadmill.

20.Do not attempt to raise, lower, or move the treadmill until it is properly assembled. (See ASSEMBLY on page 6, and HOW TO FOLD AND MOVE THE TREADMILL on page 26.) You must be able to safely lift 20 kg (45 lbs.) in order to raise, lower, or move the treadmill.

21.When folding or moving the treadmill, make sure that the storage latch is fully closed.


22.When using CD’s and videos, an electronic “chirping” sound will alert you when the speed and/or incline of the treadmill is about to change. Always listen for the “chirp” and be prepared for speed and/or incline changes. In some instances, the speed and/or incline may change before the personal trainer describes the change.

23.When using CD’s and videos, you can manually override the speed and incline settings at any time by pressing the speed and incline buttons. However, when the next “chirp” is heard, the speed and/or incline will change to the next settings of the CD or video program.

24.Always remove CD’s and videos from your CD player or VCR when you are not using them.

25.Inspect and properly tighten all parts of the treadmill regularly.

26.Never insert or drop any object into any opening.

27.DANGER: Always unplug the power cord immediately after use, before cleaning the treadmill, and before performing the maintenance and adjustment procedures described in this manual.

Before you use the chest pulse sensor, please read all instructions on this page.

The chest pulse sensor consists of two components: the chest strap and the sensor unit.

If the chest strap is not connected to the sensor unit, refer to drawing 2. Insert one of the tabs on the chest strap through one end of the sensor unit. Make sure to press the end of the sensor unit under the buckle on the chest strap—the tab should be almost flush with the sensor unit.

Sensor Buckle


Next, wrap the chest pulse sensor around your chest and attach the other end of the chest strap to the sensor unit. Adjust the length of the chest strap, if necessary. The chest pulse sensor should be under your clothes, tight against your skin, and as high under

the pectoral muscles or breasts as is comfortable. Make sure that the logo on the sensor unit is facing forward and is right-side-up.

Pull the sensor unit away from your body a few inches and locate the two electrode areas on the inner side. The electrode areas are the areas covered by shallow ridges. Using saline solution such as saliva or contact lens solution, wet both electrode areas. Return the sensor unit to a position against your chest.


Thoroughly dry the chest pulse sensor after each use. The chest pulse sensor is activated when the electrode areas are wetted and the heart rate monitor is put on; the chest pulse sensor shuts off when it is removed and the electrode areas are dried. If the chest pulse sensor is not dried after each use, it may remain activated longer than necessary, draining the battery prematurely.

Store the chest pulse sensor in a warm, dry place. Do not store the chest pulse sensor in a plastic bag or other container that may trap moisture.

Do not expose the chest pulse sensor to direct sunlight for extended periods of time.

Do not expose the chest pulse sensor to temperatures above 50° C (122° F) or below -10° C (14° F).

Do not excessively bend or stretch the sensor unit when using or storing the chest pulse sensor.

Clean the sensor unit periodically using a damp cloth; never use alcohol, abrasives, or chemicals. The chest strap may be hand washed and air dried.


The instructions on the following pages explain how the chest pulse sensor is used with the console. If the letters “PLS” appear in the Heart Rate/Calories display, or if the displayed heart rate is excessively high or low, try the steps below.

Make sure that you are wearing the chest pulse sensor as described at the left. If the chest pulse sensor does not function when positioned as described, move it slightly lower or higher on your chest.

Use saline solution such as saliva or contact lens solution to wet the two electrode areas on the sensor unit. If heart rate readings do not appear until you begin perspiring, re-wet the electrode areas.

As you walk or run on the treadmill, position yourself near the centre of the walking belt. For the console to display heart rate readings, the user must be within arm’s length of the console.


The CR2032 battery may need to be replaced. Follow the steps below to replace the battery.

Locate the battery

Battery Cover

cover on the back of


the sensor unit. Insert a


coin into the slot in the


cover and turn the


cover counterclockwise


to the “open” position.


Remove the cover.


Next, remove the old battery from the sensor unit. Insert a new CR 2032 battery, making sure that the writing is on top. In addition, make sure that the rubber gasket is in place in the sensor unit. Replace the battery cover and turn it to the closed position.







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

TANT: 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.


This product must be earthed. If it should malfunction or break down, earthing 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-earthing conductor and an earthing plug.

Two power cords are included. Select the one that will fit your outlet. Refer to drawing 1, and plug the indicated end of the power cord into the socket on the treadmill. Next, lift the indicated tab on the ferrite box and clamp the ferrite box around the power cord. The ferrite box should not be allowed to slide along the power cord. Fasten the included plastic tie just behind the ferrite box and cut off the excess plastic tie. Refer to drawing 2. Plug the power cord into an appropriate outlet that is properly installed and earthed in accordance with all local codes and ordinances. Note: In Italy, an adaptor (not included) must be used between the power cord and the outlet. Important: The treadmill is not compatible with GFCI-equipped outlets.

If the power cord is damaged, it must be replaced with a manufac- turer-recommended power cord.

The advanced console offers an impressive array of features to help you get the most from your exercise. When the console is in the manual mode, the speed and incline of the treadmill can be changed with a touch of a button. As you exercise, the console will provide continuous exercise feedback. You can even measure your heart rate using the handgrip pulse sensor or the chest pulse sensor.

Five preset workout programs are also offered. Each program automatically controls the speed and incline of the treadmill to give you an effective workout. The included hand weights let you add upper-body exercise to your workouts as well. You can even create your own custom workout programs and store them in memory for future use.

In addition, the console offers a fitness test program that measures your relative fitness level and a pulsedriven program that automatically adjusts the speed and incline of the treadmill to keep your heart rate near a target level during your workout. Note: The fitness test program and the pulse-driven program require the use of the chest pulse sensor.

The console also features new interactive


technology. technology is like having a personal trainer right in your home. Using the included audio cable, you can connect the treadmill to your home stereo, portable stereo, or computer and play special CD programs ( CD’s are available separately). CD programs automatically control the speed and incline of the treadmill as a personal trainer guides you through every step of your workout. High-energy music provides added motivation. Each CD features two programs designed by certified personal trainers.

In addition, you can connect the treadmill to your VCR and TV and play video programs (videocassettes are available separately). Video programs offer the same benefits as CD programs, but add the excitement of working out with a class and an instructor—the hottest new trend at health clubs.

With the treadmill connected to your computer, you can also go to our Web site at and access basic programs, audio programs, and video programs directly from the internet. See for details.
