OPERATION AND ADJUSTMENT
THE PERFORMANT LUBETMWALKING BELT
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.
HOW TO PLUG IN THE POWER CORD
Your treadmill, like any other type of sophisticated
electronic equipment, can be seriously damaged by
sudden voltage changes in your homeÕs 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.
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.
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 productÑif it will
not fit the outlet, have a proper outlet
installed by a qualified electrician.

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 9). 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 10.
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.
d. Check the on/off switch located on the treadmill near the
power cord. The switch must be in the on position.
2. SYMPTOM: THE POWER TURNS OFF DURING USE
a. Check the circuit breaker located on the treadmill frame near the power cord (see 1. c. above). If the circuit
breaker has tripped, wait for five minutes and then press the switch back in.
b. Make sure that the power cord is plugged in.
c. Remove the key from the console. Reinsert the key fully into the console. See step 1 on page 10.
d. Make sure that the on/off switch is in the on position.
e. If the treadmill still will not run, please call our toll-free HELPLINE.
3. SYMPTOM: THE DISPLAYS OF THE CONSOLE DO NOT FUNCTION PROPERLY
a. Remove the six screws from the hood. Carefully remove the
hood. Locate the Reed Switch (21) and the Magnet (43) on the
left side of the Pulley (42). 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 1/8Ó. If necessary,
loosen the Reed Switch Screw (76) 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.

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 toll-
free HELPLINE.
5. 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.
6. 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.

CONDITIONING GUIDELINES
The following guidelines will help you to plan your exercise program. RememberÑthese 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.
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 Òtraining zone.Ó The lower two numbers are recommended
heart rates for fat burning; the higher number is the
recommended heart rate for aerobic exercise.
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.
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
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 consoleÕs FAT BURN programs (see pages 10 to 13).
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 Òaerobic.Ó 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 consoleÕs
AEROBIC programs (see pages 10 to 13).
WORKOUT GUIDELINES
Each workout should include the following three parts:
A Warm-upÑStart 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.
Training Zone ExerciseÑAfter 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 exerciseÑnever
hold your breath.
A Cool-downÑFinish each workout with 5 to 10 minutes of stretching to cool down. This will increase the
flexibility of your muscles and will help prevent post-exercise problems.
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.
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.
18
SUGGESTED STRETCHES
The correct form for several basic stretches is shown at the right. Move slowly as you stretchÑnever bounce.
1. Toe Touch Stretch
Stand with your knees bent slightly and slowly bend forward
from your hips. Allow your back and shoulders to relax as you
reach down toward your toes as far as possible. Hold for 15
counts, then relax. Repeat 3 times. Stretches: Hamstrings,
back of knees and back.
2. Hamstring Stretch
Sit with one leg extended. Bring the sole of the opposite foot
toward you and rest it against the inner thigh of your extended
leg. Reach toward your toes as far as possible. Hold for 15
counts, then relax. Repeat 3 times for each leg. Stretches:
Hamstrings, lower back and groin.
3. Calf/Achilles Stretch
With one leg in front of the other, reach forward and place your
hands against a wall. Keep your back leg straight and your
back foot flat on the floor. Bend your front leg, lean forward and
move your hips toward the wall. Hold for 15 counts, then relax.
Repeat 3 times for each leg. To cause further stretching of the
achilles tendons, bend your back leg as well. Stretches:
Calves, achilles tendons and ankles.
4. Quadriceps Stretch
With one hand against a wall for balance, reach back and
grasp one foot with your other hand. Bring your heel as close
to your buttocks as possible. Hold for 15 counts, then relax.
Repeat 3 times for each leg. Stretches: Quadriceps and hip
muscles.
5. Inner Thigh Stretch
Sit with the soles of your feet together and your knees outward.
Pull your feet toward your groin area as far as possible. Hold
for 15 counts, then relax. Repeat 3 times. Stretches:
Quadriceps and hip muscles.
