HOW TO PLUG IN THE POWER CORD

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.

tric 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

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 SEARS store or call the
telephone number on the back cover of this manual and order part number 146148, or see your local
electronics store.
Use only a single-outlet surge suppressor that is
UL 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, accelerate 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 elec-

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.

HOW TO USE THE STEREO SOUND SYSTEM

THE INFORMATION MODE

To play music or audio books through the console’s
stereo speakers, you must connect your MP3 player,
CD player, or other personal audio player to the console. Locate the audio wire below the display on the
console, and plug it into a jack on your MP3 player,
CD player, or other personal audio player. Make sure
that the audio wire is fully plugged in.

The console features an information mode that keeps
track of treadmill usage information and allows you to
select a unit of measurement for the console.

will appear in the lower right
display. Press the Speed increase button to change the
unit of measurement, if desired.

If you are using a personal CD player and the CD
skips, set the CD player on the floor or another flat surface instead of on the console.

The upper display will show the total number of hours
that the treadmill has been used.
The lower left display will show the total number of
miles or kilometers that the walking belt has moved.
Note: The console features a display demo mode, designed to be used if the treadmill is displayed in a
store. While the demo mode is turned on, the console
will function normally when you plug in the power cord,
switch the circuit breaker to the reset position, and insert the key into the console. However, when you remove the key, the displays will remain lit, although the
buttons will not function. If the demo mode is turned
on, a “d” will appear in the lower right display while the

TROUBLESHOOTING
Most treadmill problems can be solved by following the steps below. Find the symptom that applies, and
follow the steps listed. If further assistance is needed, see the back cover of this manual.
PROBLEM: The power does not turn on
SOLUTION: a. Make sure that the power cord is plugged into a surge suppressor, and that the surge suppressor
is plugged into a properly grounded outlet (see page 12). Use only a single-outlet surge suppressor that meets all of the specifications described on page 12. Important: The treadmill is not compatible with GFCI-equipped outlets.
b. After the power cord has been plugged in, make sure that the key is inserted into the console.
c. Check the reset/off circuit breaker located on the
treadmill frame near the power cord. If the switch
protrudes as shown, the circuit breaker has tripped.
To reset the circuit breaker, wait for five minutes,
and then press the switch back in.

c. Remove the key from the console. Reinsert the key into the console.
d. If the treadmill still will not run, please see the back cover of this manual.
PROBLEM: The console displays remain lit when you remove the key from the console
SOLUTION: a. The console features a display demo mode, designed to be used if the treadmill is displayed in a
store. If the displays remain lit when you remove the key, the demo mode is turned on. To turn off
the demo mode, hold down the Stop button for a few seconds. If the displays are still lit, see THE
INFORMATION MODE on page 17 to turn off the demo mode.
PROBLEM: The displays of the console do not function properly

EXERCISE GUIDELINES
Burning Fat—To burn fat effectively, you must exercise at a low intensity level for a sustained period of
time. During the first few minutes of exercise, your
body uses carbohydrate calories for energy. Only after
the first few minutes of exercise does your body begin
to use stored fat calories for energy. If your goal is to
burn fat, adjust the intensity of your exercise until your
heart rate is near the lowest number in your training
zone. For maximum fat burning, exercise with your
heart rate near the middle number in your training
zone.

WARNING:

Before beginning this
or any exercise program, consult your physician. This is especially important for individuals over the age of 35 or individuals with preexisting health problems.
The pulse sensor is not a medical device.
Various factors, including your movement,
may affect the accuracy of heart rate readings.
The sensor is intended only as an exercise aid
in determining heart rate trends in general.

These guidelines will help you to plan your exercise
program. For detailed exercise information, obtain a
reputable book or consult your physician. Remember,
proper nutrition and adequate rest are essential for
successful results.

Aerobic Exercise—If your goal is to strengthen your
cardiovascular system, you must perform aerobic exercise, which is activity that requires large amounts of
oxygen for prolonged periods of time. For aerobic exercise, adjust the intensity of your exercise until your
heart rate is near the highest number in your training
zone.

EXERCISE INTENSITY

WORKOUT GUIDELINES

Whether your goal is to burn fat or to strengthen your
cardiovascular system, exercising at the proper intensity is the key to achieving results. You can use your
heart rate as a guide to find the proper intensity level.
The chart below shows recommended heart rates for
fat burning and aerobic exercise.

Warming up—Start with 5 to 10 minutes of stretching
and light exercise. A warm-up increases your body
temperature, heart rate, and circulation in preparation
for exercise.
Training Zone Exercise—Exercise for 20 to 30 minutes with your heart rate in your training zone. (During
the first few weeks of your exercise program, do not
keep your heart rate in your training zone for longer
than 20 minutes.) Breathe regularly and deeply as you
exercise–never hold your breath.
Cooling down—Finish with 5 to 10 minutes of stretching. Stretching increases the flexibility of your muscles
and helps to prevent post-exercise problems.
EXERCISE FREQUENCY

To find the proper intensity level, find your age at the
bottom of the chart (ages are rounded off to the nearest ten years). The three numbers listed above your
age define your “training zone.” The lowest number is
the heart rate for fat burning, the middle number is the
heart rate for maximum fat burning, and the highest
number is the heart rate for aerobic exercise.

To maintain or improve your condition, complete three
workouts each week, with at least one day of rest between workouts. After a few months of regular exercise, you may complete up to five workouts each
week, if desired. Remember, the key to success is to
make exercise a regular and enjoyable part of your
everyday life.
