CAUTION: What follows are general recommendations and
should only be used as such. Please modify these recommenda¬
tions to accommodate your personal fitness level.
It is extremely important to discuss your exercise plans with
your physician prior to working out so that you develop a
program appropriate for your level of fitness. I fat any time you
should feel faint, dizzy, nauseous, experience heart palpita¬
tions, or any other abnormal symptoms or discomfort,
discontinue use and consult your physician.
INTRODUCTION _
The Tunturi J550 is designed for a variety of fitness needs and
is conducive for walking, jogging, and/or running. All three
modes of exercise, when performed consistently, will improve
the quality of life.
Your goal may he to: f
I n c tease card i ovascu 1 a r fi t ness , :'U
Increase lung capacity
Increase circulation
Increase muscular strength’ and endurance
Increase bone strength
Or you may want to:
Decrease body fat
D ec re as e s t res s
Decreasccholesterol -iMK:
Decrease blood iiressure
PHILOSOPHY ___
Though the heart is the primary muscle targeted in any aerobic
workout, muscle enhancement in other areas of the body,
specifically the lower extremity, is important. When the same
muscle group is moved at a different angle, a different part of
that muscle group is strengthened. The end result is a more
complete development of the entire muscle group,
AEROBIC EXERCISE _
The Tunturi treadmill is an aerobic exercise device and func¬
tions primarily to increase aerobic capacity. The benefits of
aerobic exercise have been found to strengthen

ness, i m p j:o ve hlo o d ci r cu 1 a c i o n, i ncrease ho n c
density, strengthen the heart, lower blood
cholesterol, aid digestion, reduce stress, de-
crease body fat, and increase metabolic
j'a te.
Aerobic exercise refers to a physical ac-
' tivity which requires large amounts of
oxygen for prolonged periods.
During aerobic workout, strenuous de-
fffit .Yfff mands are placed on the heart and lungs;
ffff' t h e h e a r t p u in ps q u i ck i y to s p read b 1 o o d to
/iff"' the muscles, and the lungs work hard to
oxygenate that blood. As you work to oxygenate
the blood for your muscles, your entire card iovas-
cular system becomes stronger and your muscles
' get leaner.
Also, the energy used to work muscles comes from body fat.
Aerobic exercise is the best way to burn fat as well as strengthen
Tunturi has carefully researched your fitness needs and de¬
signed programs with every fitness level in mind. Exercise has
been shown to enhance the quality of life and we would like to
see everyone move to a higher degree of fitness. Motivation is
a key to success of this endeavor, so throughout the design
process, motivation was considered.
OBJECTIVE _
The objective, as with all fitness programs, is optimal health
and fitness. Age, sex, body weight, and current fitness levels all
combine to determine the intensity of the workout. The opti¬
mal aerobic program varies the muscle involvement from
workout to workout. This is called cross training, it enables you
to involve the maximum amount of muscle fiber throughout
the week by varying the type of aerobic exercise.
and tone muscles.
AEROBIC TRAINING ZONE _
Your Aerobic Training Zone is the workout intensity chat will
yield the greatest benefits to you. The Institute for Aerobics
Research recommends that this Aerobic Training Zone fall
between 60% and 80% of your maximum heart rate (the fastest
your heart can physically heat). NOTE: A maximum heart rate up
to 85% is acceptable for developed or adt^anced aerobic exercisers.
The Heart Rate Chart shown on the next page offers a quick
reference and a rough approximation of your Aerobic Training
Zone. It is based only upon age and since fitness levels vary
dramatically within an age group, wc highly recommend that
you consult your physician to determine your exact training
zone.

MONITORING YOUR HEART RATE _
It is very important to monitor your heart rate throughout the
exercise session. Your heart rate indicates the intensity of your
workout. Many people begin an exercise program too zealously
and discontinue because it becomes too difficult. Exercise
should be a pleasant experience, and exercising at the correct
intensity level will enhance the pleasure.
You should check your heart rate periodically throughout your
workout to verify that you are exercising in your training zone.
If you do not have an electronic pulse monitor, use the
SIX^^SECQND MANUAL COUNT METHOD: _
1 Slow down or stop briefly.
2 Lightly place your index and second finger at the side of
your neck or to the thumb-side or your wrist,
3 Count your pulse beats for six seconds.
4 Multiply the number of pulse beats by 1 0 to calculate your
heart rate.

AGE YEARS
To gain the benefits of aerobic
exercise, you must maintain your
heart rate within your training
zone for at least 1 2 uninterrupted
minutes. IF you’re beginning an
exercise program, stay at the 12-
minute minimum for at least
one week. Increase your time by
no more than 10 percent each
week.
People in excellent cardiovascu¬
lar shape can exercise for longer
periods of time because their
heart, muscles, and bones have
developed to handle it. Increase
duration as your strength in¬
creases, But, remember, it takes
time to strengthen all of the body’.s systems. Please, listen to
your body, and know your limits. If you exercise longer than 60
minutes, benefits are reduced and risk of injury is increased. If
you experience dizziness, nausea, chest pain, or other abnormal
symptoms, stop immediately. Consult a physician before con-
tin uing.
THE FOLLOWING GUIDELINES MUST BE OBSERVED
PRIOR TO OPERATION _
CAUTION: Failure to follow these guidelines may lead to
serious injury and cause damage to the treadmill.
The floor must be solid, and level. It must be clean and lint-free.
Do not use the treadmill on a carpet that is greater than 1/2 inch
in height.
'There must be at least four feet of clearance behind the tread¬
mill and at least two feet on the other three sides, (FIG. 10}
Position the treadmill so you have complete visibility on all
sides. This is especially important in homes with children and
pets.
This unit must be plugged into a dedicated and grounded 11 5V
AC/20 amp electrical outlet with a constant 115 volts measured
at the treadmill.
Before each use, you must check that the running belt is aligned
and centered on the treadmill bed and that all visible compo¬
nents and fasteners are sufficiently tigthened and secure.

POLAR® HEART RATE TECHNOLOGY_
All Tunturi Electronic Treadmills are manufactured with heart
rate monitoring capability. A Polar Pulse Transmitter and Belt
(see FIG. 1) are accessories that are necessary in order to take
advantage of this technology. These items may be purchased
separately for the J550. Please contact your Tunturi Retailer if
you are interested in purchasing the transmitter & belt.
US I N G T H E POLATRANSMI T T E R & BELT_
1 Attach the elastic chest belt to the pulse transmitter. (FIG.2)
2 Wrap the belt around your chest and fasten it together.
Adjust the belt so it will remain tight and not bounce up
and down. (FIG. 3)
3 The transmitter should be above your stomach and at the
center of your chest, against your skin. (FIG. 4)
4 Under extreme sweat conditions, it may be necessary to wear
the belt and transmitter over a light shirt to prevent irregular
readings. (FIG. 5)
MON I T O R I N G PUL S E WITH YO U R TREADMILL _
1 Turn drt the treadmill.
2 Begin your workout. See Steps 1—6;
“Operating The Treadmill”, pages 14—15.
3 Pulse or heart rate will read on the Computer Display
when the small light is ON next to the PULSE label.
Also see Developing An Exercise Program*' pages 8 & 9.
P U L S E M O N I T O R IN F O R M A T I O N & PRECA U T I O N S : _
• The belt should be cleaned, as needed, with a mild soap and
water solution. Never use alcohol or any abrasives as these
will cause permanent damage.
• To maximize the life of your belt, be sure that you do not
stretch or bend the electrode strips (take special care when
storing it).
• The Transmitter is switched to an active state only when it
is being used for measurement. However, we recommend
that you detach the Transmitter from the Belt after use
because sweat and other moisture can keep the Transmitter
in an active state and waste battery energy.
• The Transmitter should last for a number of years.
Replacement Transmitters and/or Belts are available
from Tunturi, Inc.
• Do not use the Transmitter together with a heart pacemaker.
• Strong electromagnetic fields, emitted from televisions,
radios, antennae, or high voltage power lines may
produce irregular readings.
