IMPORTANT SAFETY PRECAUTIONS
^A.=

WARNING:

To reduce the risk of burns, fire, electric shock or injury to persons, read the following important safety precautions and information before operating the treadmill.

1. Position the treadmill on a level surface, with at least 8 feet of clearance behind 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.
2. When connecting the power cord (see PLUGGING IN THE POWER CORD on page 6 and 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 needed, use only a 14-gauge general-purpose cord of five feet or less in length with a three-wire
conductor.
3. 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.)
4. 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.
5. The pulse earclip is not a medical device. Various factors, including the user's movement while exercising, may affect the accuracy of heart rate readings. The earcUp is intended only as an exercise aid
in determining heart rate trends in general.
6. Never start the treadmill while you are standing on the walking belt. Always hold the handrail when
exercising on the treadmill.
7. Never allow more than one person on the treadmill at a time. The treadmill should not be used by persons weighing more than 250 pounds.
8. Keep small children away from the treadmill at all times. Never leave the treadmill unattended while it
Is running. Always turn the power off when the treadmill is not in use.
9. Never drop or insert any object into any opening.
10. To reduce the possibility of overheating, do not operate the treadmill continuously for longer than 1
hour.
11. The treadmill is capable of high speeds. Adjust the speed slowly to avoid sudden jumps in speed.
12. Use the treadmill only as described in this manual.
13. Always unplug the power cord before performing the maintenance and adjustment procedures
described in this manual. Never remove the safety cover unless instructed to do so by an authorized
service representative. Servicing other than the procedures in this manual should be performed by an
authorized service representative only.

OPERATION AND ADJUSTMENT
PLUGGING IN THE POWER CORD

6

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.

DANG ER:

Improper connection of the equipment-grounding

conductor can result in a risk of elec-

tric 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.
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.
A temporary adapter that looks like the adapter illustrated in Drawing 2 may be used to connect this plug to a 2pole 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.

IN THE MAINTENANCE-FREE

WALKING

PLATFORM

IMPORTANT:This treadmill features a maintenance-free walking platform. After completion of the following
break-In procedure, the walking platform requires no further maintenance. The walking platform must be broken
in completely so that the coating on the walking platform impregnates the walking belt. If this is not done, the
treadmill may function erratically. Follow the steps below to break in the walking platform completely.
1. Adjust the incline of the treadmill to the highest setting. (See INCLINE CONTROL on page 9.)
2. Adjust the speed of the walking belt to about 3 or 4 miles per hour. (See SPEED CONTROL on page 8.) Hold
the handrail and begin walking on the treadmill. Be sure to walk on all areas of the walking belt---not only
on the center. Continue for 5 to 10 minutes, or until the walking belt no longer slows as you walk.
3. To complete the break-in procedure, first stop the walking belt
and unplug the power cord. Lift each side of the walking belt
and apply the included lubricant generously to the area of the
walking platform shown at the right. This one-time application
completes the break-in of the maintenance-free walking platform.
IMPORTANT: The included 100% silicone lubricant is specially
formulated for this one-time application. Do not apply any other silicone lubricant or spray. Such substances may damage the walking platform and cause excessive wear or premature failure of the
treadmill.

Apply lubricant to
entire shaded area.

Note: The treadmill may function erratically during the break-in procedure. The walking belt may slow to a stop or
surge in speed, and an error code ('El ," =E2," "E3," etc.) may appear in the SPEED display. If this happens,
remove the safety key, wait for ten seconds and then reinsert it.

CONDITIONING

GUIDELINES

The following guidelines will help you to plan your exercise program. Remember that proper nutrition and adequate rest are essential for successful results.

kWARNING:

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 foundby 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.

WAR NING:

^,.=
The pulse earclip Is not a medical device. Various factors, including your movement 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
cool-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 exercise 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
The following stretches can provide a good warm-up or cool-down. Correct form for each stretch is shown in the
drawings below. Move slowly as you stretch--never bounce.
TOE TOUCH STRETCH
