ASSEMBLY
Assembly requires two people. Set the treadmill in a cleared area and remove all packing materials. Do not
dispose of the packing materials until assembly is completed. No tools are required for assembly.
Note: The underside of the treadmill walking belt is coated with high-performance lubricant. During shipping, a
small amount of lubricant may be transferred to the top of the walking belt or the shipping carton. This is a normal
condition and does not affect treadmill performance. If there is lubricant on top of the walking belt, simply wipe off
the lubricant with a soft cloth and a mild, non-abrasive cleaner.
1. With the help of a second person, carefully raise the
Uprights (15) until the treadmill is in the position shown.

THE PERFORMANT
LUBE TM WALKING BELT
Your treadmill features a walking belt coated with
PERFORMANT
LUBE TM, 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.
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.

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.

Grounded Outlet
Grounding Plug
Grounded Outlet Box
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).
Surge suppressors are sold at most hardware stores
and department stores. 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.
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.
Adapter
Metal Screw
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.

water bottle in the water bottle holder.
FEATURES OF THE CONSOLE
The treadmill console offers an impressive array of
features designed to help you get the most from your
workouts. When the manual mode is selected, the
speed and incline of the treadmill can be changed with
a touch of a button. As you exercise, an LED "track"
and four displays will provide continuous exercise feedback. With the built-in pulse sensor, you can even
measure your heart rate.
In addition, the console offers six workout programs.
Three programs automatically control the incline of the
treadmill and three programs control the speed of the
treadmill as they guide you through effective workouts.
Note: The treadmill console can display speed and
distance in either miles or kilometers (see SPEED/
PACE DISPLAY on page 9). For simplicity, all instructions in this section refer to miles.

MAINTENANCE
AND TROUBLE-SHOOTING
Most treadmill problems can be solved by following the simple steps below. Find the symptom that
applies, and follow the steps listed. If further assistance is needed, call our toll-free HELPLINE at
1-800-736-6879, Monday through Saturday, 7 a.m. until 7 p.m. Central Time (excluding holidays).
1. SYMPTOM: THE POWER DOES NOT TURN ON
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 7). 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.
b. After the power cord has been plugged in, make sure that the key is inserted into the console as far as it will
go. See step 1 on page 8.
c. Check the circuit breaker located on the treadmill 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.

e. If the treadmill still will not run, please call our toll-free HELPLINE
3. SYMPTOM: THE PULSE SENSOR DOES NOT FUNCTION PROPERLY
a. Make sure to stand on the foot rails and avoid moving your hands while measuring your heart rate.
Excessive movement may interfere with heart rate readings. If the pulse sensor is not used correctly, your
heart rate will not be shown.
b. Do not hold the metal contacts too tightly; doing so may interfere with heart rate readings.
c. For the most accurate heart rate reading, hold the contacts for about 15 seconds.
d. For optimal performance of the pulse sensor, keep the contacts clean. The contacts can be cleaned with a
soft cloth--never use alcohol, abrasives, or chemicals.

4. SYMPTOM: THE DISPLAYS OF THE CONSOLE DO NOT FUNCTION PROPERLY
a. Remove the key from the console and UNPLUG THE POWER
CORD. Remove the screws from the hood. Carefully remove the
hood. Locate the Reed Switch (26) and the Magnet (107) on the
left side of the Pulley (12). Turn the Pulley until the Magnet is
aligned with the Reed Switch. Make sure that the gap between
the Magnet and the Reed Switch is about 1/8". If necessary,
loosen the Reed Switch Screw (109) and move the Reed Switch
slightly. Retighten the Screw. Re-attach the hood, and run the
treadmill for a few minutes to check for a correct speed reading.
5. SYMPTOM: The walking
belt slows when walked on
a. Use only a UL-listed surge protector, rated at 15 amps, with a 14-gauge cord of five feet or less in length.
b. If the walking belt is overtightened, treadmill performance may
decrease and the walking belt may be permanently damaged.
Remove the key and UNPLUG THE POWER CORD. Using the
allen wrench, turn both rear roller adjustment bolts counterclockwise, 1/4 of a turn. When the walking belt is properly tightened,
you should be able to lift each side of the walking belt 3 to 4
inches off the walking platform. Be careful to keep the walking
belt centered. Plug in the power cord, insert the key and run the
treadmill for a few minutes. Repeat until the walking belt is properly tightened.
c. If the walking belt still slows when walked on, please call our tollfree HELPLINE.
6. SYMPTOM: The walking belt is off-center
a. If the walking belt has shifted to the left, first remove the key and
UNPLUG THE POWER CORD. Using the allen wrench, turn the
left rear roller adjustment bolt clockwise, and the right bolt counterclockwise, 1/4 of a turn each. Be careful not to overtighten the
walking belt. Plug in the power cord, insert the key and run the
treadmill for a few minutes. Repeat until the walking belt is centered.
b. If the walking belt has shifted to the right, first remove the key
and UNPLUG THE POWER CORD. Using the allen wrench, turn
the left rear roller adjustment bolt counterclockwise, and the right
bolt clockwise, 1/4 of a turn each. Be careful not to overtighten
the walking belt. Plug in the power cord, insert the key and run
the treadmill for a few minutes. Repeat until the walking belt is
centered.
7. SYMPTOM: The walking belt slips when walked on
a. If the walking belt slips when walked on, first remove the key and
UNPLUG THE POWER CORD. Using the allen wrench, turn
both rear roller adjustment bolts clockwise, 1/4 of a turn. When
the walking belt is correctly tightened, you should be able to lift
each side of the walking belt 3 to 4 inches off the walking platform. Be careful to keep the walking belt centered. Plug in the
power cord, insert the key and carefully walk on the treadmill for
a few minutes. Repeat until the walking belt is properly tightened.

GUIDELINES
uses easily accessible carbohydrate calories for energy. Only after the first few minutes does your body
begin to use stored fat calories for energy. If your goal
is to burn fat, adjust the speed and incline of the treadmill until your heart rate is near the lowest number in
your training zone. It may also be helpful to use one of
the console's FAT BURN programs (see pages 10 to 13).
G: 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.
For maximum fat burning, adjust the speed and incline
of the treadmill until your heart rate is near the middle
number in your training zone.
Aerobic Exercise
If your goal is to strengthen your cardiovascular system, your exercise must be "aerobic." Aerobic exercise
is activity that requires large amounts of oxygen for
prolonged periods of time. This increases the demand
on the heart to pump blood to the muscles, and on the
lungs to oxygenate the blood. For aerobic exercise,
adjust the speed and incline of the treadmill until your
heart rate is near the highest number in your training
zone. It may also be helpful to use one of the console's
AEROBIC programs (see pages 10 to 13).
The following guidelines will help you to plan your exercise program. Remember--these are general guidelines only. For more detailed exercise information, obtain a reputable book or consult your physician.
EXERCISE INTENSITY
Whether your goal is to burn fat or to strengthen your
cardiovascular system, the key to achieving the
desired results is to exercise with the proper intensity.
The proper intensity level can be found by using your
heart rate as a guide. The chart below shows recommended heart rates for fat burning and aerobic exercise.

GUIDELINES
Each workout should include the following three parts:
A Warm-up--Start
each workout with 5 to 10 minutes
of stretching and light exercise. A proper warm-up increases your body temperature, heart rate and circulation in preparation for exercise.

ATe%

Training Zone Exercise--After warming up, increase
the intensity of your exercise until your pulse is in your
training zone for 20 to 60 minutes. (During the first few
weeks of your exercise program, do not keep your
pulse in your training zone for longer than 20 minutes.)
Breathe regularly and deeply as you exercise--never
hold your breath.
To find the proper heart rate for you, first find your age
near the bottom of the chart (ages are rounded off to
the nearest ten years). Next, find the three numbers
above your age. The three numbers define your "training zone." The lower two numbers are recommended
heart rates for fat burning; the higher number is the
recommended heart rate for aerobic exercise.
A Cool-down--Finish
each workout with 5 to 10 min-
utes of stretching to cool down. This will increase the
flexibility of your muscles and will help prevent post-exercise problems.
To measure your heart rate during exercise, use the
pulse sensor on the console. If your heart rate is too
high or too low, adjust the speed and incline of the
treadmill.
Exercise Frequency
To maintain or improve your condition, complete three
workouts each week, with at least one day of rest between workouts. After a few months, you may complete up to five workouts each week if desired. The key
to success is to make exercise a regular and enjoyable
part of your everyday life.
Fat Burning
To burn fat effectively, you must exercise at a relatively
low intensity level for a sustained period of time.
During the first few minutes of exercise, your body
