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.

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. (This chart is also found on the console.)
To find the proper heart rate for you, first find your age
on the left side of the chart (ages are rounded off to
the nearest ten years). Next, find the three numbers to
the right of your age. The three numbers are 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.
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 one of the lower two numbers in your
training zone. It may also be helpful to set the speed
control on the console to FAT BURN to help you maintain the proper intensity level. (See page 9.)
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 set the speed control on
the console to AEROBIC to help you maintain the
proper intensity level. (See page 9.)
High Performance Athletic Conditioning
If your goal is high performance athletic conditioning,
set the speed control on the console to PERFORMANCE to help you maintain the proper intensity level.
(See page 9.) Note: During the first few weeks of your
exercise program, keep your heart rate near the low
end of your training zone.
HOW TO MEASURE YOUR HEART RATE
To measure your
heart rate, stop exercising and place
two fingers on
your wrist as
shown. Take a sixsecond heartbeat
count, and multiply
the result by ten to
find your heart
rate. (A six-second count is used because your heart
rate drops quickly when you stop exercising.) If your
heart rate is too high or too low, adjust the speed or incline of the treadmill accordingly.
WORKOUT GUIDELINES
A well-rounded workout includes the following three
important parts:
A Warm-up
Start each workout with 5 to 10 minutes of stretching
and light exercise (see SUGGESTED STRETCHES on
page 14). A proper warm-up increases your body
temperature, heart rate, and circulation in preparation
for exercise.
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 pre-existing health problems.
13
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 exerciseÑnever hold your breath.
A Cool-down
Finish each workout with 5 to 10 minutes of stretching
to cool down. This will increase the flexibility of your
muscles and will help to 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.
SUGGESTED STRETCHES
The correct form for several basic stretches is shown in the
drawings below. 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 both legs. 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.
