IMPORTANT PRECAUTIONS
WARNING: To reduce the risk of burns, fire, electric shock or injury to persons, read the fol-
lowing important precautions and information before operating the treadmill.
1. It is the responsibility of the owner to ensure that all users of this treadmill are adequately informed
of all warnings and precautions.
.Position the treadmill on a level surface, with at least 8 feet of clearance behind the treadmill. To pro-
tect the floor or carpet from damage, place a mat under the treadmill. Do not place the treadmill near
water, outdoors or on any surface that blocks an air opening. Do not operate where aerosol products
are used or where oxygen is being administered.
.When connecting the power cord (see PLUGGING IN THE POWER CORD on page 7), plug the power
cord directly into a grounded circuit capable of carrying 12 or more amps. No other appliance should
be on the same circuit. Keep the power cord away from heated surfaces. If an extension cord is need-
ed, use only a 14-gauge general-purpose cord of five feet or less in length with a three-wire conductor.
4,
.
Never move the walking belt while the power is turned off. Do not operate the treadmill if the power
cord or plug is damaged, or if the treadmill is not working properly. (See BEFORE YOU BEGIN on
page 5 if the treadmill is not working properly.)
Wear appropriate exercise clothing when using the treadmill; do not wear loose clothing that could
become caught in the treadmill. Always wear athletic shoes; never use the treadmill with bare feet,
wearing only stockings or in sandals. Athletic support clothes are recommended for both men and
women.
6. The pulse earclip is not a medical device. Various factors, including the user's movement while exer-
cising, may affect the accuracy of heart rate readings. The earclip is intended only as an exercise aid
in determining heart rate trends in general.
7. Never start the treadmill while you are standing on the walking belt. Always hold the handrail when
exercising on the treadmill.
8. Never allow more than one person on the treadmill at a time. The treadmill should not be used by per-
sons weighing more than 250 pounds.

OPERATION AND ADJUSTMENT
THE PERFORMANT LUBE TM WALKING BELT
Your treadmill features awalking belt coated with PERFORMANT LUBET% a high-performance lubricant.
During the first few hours of use, it is normal for a small amount of white powder to appear on the foot rails and
the walking platform. The white powder is high-performance lubricant from the walking belt.
IMPORTANT: Never apply silicone spray or other substances to the walking belt or the walking platform.
They will deteriorate the walking belt and cause excessive wear.
PLUGGING IN THE POWER CORD
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 an appropriate outlet that is
properly installed and grounded in accordance with all local codes and ordinances.
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 prod-
uct is properly grounded. Do not modify the plug provided with the product--if it will not fit the outlet, have a prop-
er outlet installed by a qualifiedelectrician.
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.
Atemporary adapter that looks like the adapter illustrated in Drawing 2 may be used to connect this plug to a 2-
pole receptacle as sfiO_hn 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.

CONDITIONING GUIDELINES
The following guidelines will help you to plan your exercise program. Remember that proper nutrition and ade-
quate rest are essential for successful results.
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.
EXERCISE INTENSITY
To maximize the benefits of exercising, it is important to exercise with the proper intensity. The proper intensity
level can be found by using your heart rate as a guide. For effective aerobic exercise, your heart rate should be
maintained at a level between 70% and 85% of your maximum heart rate as you exercise. This is known as your
training zone. You can find your training zone in the table below.

During the first few months of your exercise program, keep your heart rate near the low end of your training zone
as you exercise. After a few months of regular exercise, your heart rate can be increased gradually until it is near
the middle of your training zone as you exercise. You can measure your heart rate using the pulse mode of the
console. Exercise for at least four minutes, and then measure your heart rate immediately. If your heart rate is too
high, decrease the intensity of your exercise. If your heart rate is too low, increase the intensity of your exercise.
^Aa_WAR NING: The pulse earclip is not a medical device. Various factors, including your move-
ment during exercise, may affect the accuracy of heart rate readings. The earclip is intended only as an
exercise aid in determining heart rate trends in general.
WORKOUT GUIDELINES
Each workout should consist of three basic parts: a warm-up, 20 to 30 minutes of training zone exercise, and a
coot-down. Warming up prepares the body for exercise by increasing circulation, delivering more oxygen to the
muscles and raising the body temperature. Begin each workout with 5 to 10 minutes of stretching and light exer-
cise to warm up. Then, increase the intensity of your exercise to raise your heart rate to your training zone for 20
to 30 minutes. Breathe regularly and deeply as you exercise--never hold your breath. Finish each workout with 5
to 10 minutes of stretching to cool down. This will increase the flexibility of your muscles as well as help to
decrease soreness and other post-exercise problems.
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.
The key to success is CONSISTENCY.
12

SUGGESTED STRETCHES
