IMPORTANT PRECAUTIONS  
WARNING:  
To reduce the risk of burns, fire, electric shock, or injury to persons, read the  
following 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.  
12. Failure to use a properly functioning surge  
suppressor could result in damage to the con-  
trol system of the treadmill. If the control sys-  
tem is damaged, the walking belt may change  
speed or stop unexpectedly, which may result  
in a fall and serious injury.  
2. Use the treadmill only as described.  
3. Place the treadmill on a level surface, with at  
least eight feet of clearance behind it and two  
feet on each side. Do not place the treadmill  
on any surface that blocks air openings. To  
protect the floor or carpet from damage, place  
a mat under the treadmill.  
13. Keep the power cord and the surge suppres-  
sor away from heated surfaces.  
14. 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 BE-  
FORE YOU BEGIN on page 5 if the treadmill is  
not working properly.)  
4. Keep the treadmill indoors, away from mois-  
ture and dust. Do not put the treadmill in a  
garage or covered patio, or near water.  
5. Do not operate the treadmill where aerosol  
products are used or where oxygen is being  
administered.  
15. Never start the treadmill while you are stand-  
ing on the walking belt. Always hold the  
handrails while using the treadmill.  
6. Keep children under the age of 12 and pets  
away from the treadmill at all times.  
16. The treadmill is capable of high speeds.  
Adjust the speed in small increments to avoid  
sudden jumps in speed.  
7. The treadmill should be used only by persons  
weighing 250 pounds or less.  
17. 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.  
8. Never allow more than one person on the  
treadmill at a time.  
9. Wear appropriate exercise clothes when  
using the treadmill. Do not wear loose clothes  
that could become caught in the treadmill.  
Athletic support clothes are recommended for  
both men and women. Always wear athletic  
shoes. Never use the treadmill with bare feet,  
wearing only stockings, or in sandals.  
18. Do not use the hand weights at speeds faster  
than walking speeds. Using weights and not  
holding the handrails may compromise your  
ability to maintain your balance. Exercises  
using weights should be attempted only by  
experienced users.  
10. When connecting the power cord (see page 10),  
plug the power cord into a surge suppressor  
(not included) and plug the surge suppressor  
into a grounded circuit capable of carrying 15  
or more amps. No other appliance should be on  
the same circuit. Do not use an extension cord.  
19. Never leave the treadmill unattended while it  
is running. Always remove the key and unplug  
the power cord when the treadmill is not in  
use.  
20. Do not attempt to raise, lower, or move the  
treadmill until it is properly assembled. (See  
ASSEMBLY on page 6, and HOW TO FOLD  
AND MOVE THE TREADMILL on page 14.)  
You must be able to safely lift 45 pounds (20  
kg) to raise, lower, or move the treadmill.  
11. Use only a single-outlet surge suppressor that  
meets all of the specifications described on  
page 10. To purchase a surge suppressor, see  
your local Sears or call 1-800-366-7278 and  
order part number 146148.

OPERATION AND ADJUSTMENT  
THE PERFORMANT LUBETM WALKING BELT  
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.  
Important: The treadmill is not compatible with  
GFCI-equipped outlets.  
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 plat-  
form. Such substances will deteriorate the walking  
belt and cause excessive wear.  
This product is for use on a nominal 120-volt circuit,  
and has a grounding plug that looks like the plug illus-  
trated 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.  
HOW TO PLUG IN THE POWER CORD  
DANGER:  
Improper connection  
of the equipment-grounding conductor can  
result in an increased risk of electric shock.  
Check with a qualified electrician or service-  
man if you are in doubt as to whether the  
product is properly grounded. Do not modify  
the plug provided with the productif it will  
not fit the outlet, have a proper outlet

Your treadmill, like any other type of sophisticated  
electronic equipment, can be seriously damaged by  
sudden voltage changes in your homes 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). To purchase a surge suppressor, see  
your local Sears or call 1-800-366-7278 and order  
part number 146148.

Surge Suppressor  
Use only a single-outlet surge suppressor that is  
UL 1449 listed as a transient voltage surge sup-  
pressor (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. There must be a  
monitoring light on the surge suppressor to indi-  
cate whether it is functioning properly. Failure to  
use a properly functioning surge suppressor could  
result in damage to the control system of the  
treadmill. If the control system is damaged, the  
walking belt may change speed or stop unexpect-  
edly, which may result in a fall and serious injury.  
Lug  
Metal Screw  
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 elec-  
trician to determine if the outlet box cover is  
grounded before using an adapter.  
This product must be grounded. If it should malfunc-  
tion or break down, grounding provides a path of least  
resistance for electric current to reduce the risk of elec-  
tric shock. This product is equipped with a cord having

SOLUTION: a. Use only a single-outlet surge suppressor that meets all of the specifications described on page 10.  
b. If the walking belt is overtightened, treadmill perfor-  
b
mance may decrease and the walking belt may be-  
come 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 2 to  
3 inches off the walking platform. Be careful to keep  
the walking belt centered. Plug in the power cord, in-  
sert the key, and run the treadmill for a few minutes.  
Repeat until the walking belt is properly tightened.

PROBLEM: The walking belt is off-center or slips when walked on  
SOLUTION: a. If the walking belt is off-center, first remove the key  
a
and UNPLUG THE POWER CORD. If the walking  
belt has shifted to the left, use the allen wrench to  
turn the left rear roller bolt clockwise 1/2 of a turn; if  
the walking belt has shifted to the right, turn the  
left bolt counterclockwise 1/2 of a turn. 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 slips when walked on, first remove  
b
the key and UNPLUG THE POWER CORD. Using  
the allen wrench, turn both rear roller bolts clockwise,  
1/4 of a turn. When the walking belt is correctly tight-  
ened, you should be able to lift each side of the walk-  
ing belt 2 to 3 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  
ergy. 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 tread-  
mill until your heart rate is near the lowest number in  
your training zone.  
WARNING:  
Before beginning this  
or any exercise program, consult your physi-  
cian. This is especially important for individu-  
als over the age of 35 or individuals with pre-  
existing health problems.  
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.  
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.  
Aerobic Exercise  
If your goal is to strengthen your cardiovascular sys-  
tem, your exercise must be aerobic.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.  
The following guidelines will help you to plan your ex-  
ercise program. For more detailed exercise informa-  
tion, 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 recom-  
mended heart rates for fat burning and aerobic exercise.  
WORKOUT GUIDELINES  
Each workout should include the following three parts:  
A Warm-upStart each workout with 5 to 10 minutes  
of stretching and light exercise. A proper warm-up in-  
creases your body temperature, heart rate and circula-  
tion in preparation for exercise.  
Training Zone ExerciseAfter 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 exercisenever  
hold your breath.  
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 train-  
ing zone.The lower two numbers are recommended  
heart rates for fat burning; the higher number is the  
recommended heart rate for aerobic exercise.  
A Cool-downFinish each workout with 5 to 10 min-  
utes of stretching to cool down. This will increase the  
flexibility of your muscles and will help prevent post-  
exercise problems.  
To measure your heart rate during exercise, use the  
pulse sensor.  
EXERCISE FREQUENCY  
To maintain or improve your condition, complete three  
workouts each week, with at least one day of rest be-  
tween workouts. After a few months, you may com-  
plete 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.  
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 en-
