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 product—if 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 home’s power.  
Voltage surges, spikes, and noise interference can  
result from weather conditions or from other appli-  
ances being turned on or off. To decrease the pos-  
sibility of your treadmill being damaged, always  
use a surge suppressor with your treadmill (see  
drawing 1 at the right). To purchase a surge sup-  
pressor, see your local SEARS or call toll-free 1-  
800-366-7278 and order part number 146148.

Grounded Outlet Box  
Adapter  
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

CONDITIONING GUIDELINES  
control on the console to FAT BURN to help you main-  
tain the proper intensity level. (See page 9.)  
WARNING:  
Before beginning  
this or any exercise program, consult your  
physician. This is especially important for in-  
dividuals over the age of 35 or individuals  
with pre-existing health problems.  
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. 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.)  
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 de-  
sired 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 exer-  
cise.  
High Performance Athletic Conditioning  
If your goal is high performance athletic conditioning,  
set the speed control on the console to PERFOR-  
MANCE 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 exer-  
cising and place two  
fingers on your wrist  
as shown. Take a  
six-second heartbeat  
count, and multiply  
the result by ten to  
find your heart rate.  
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  
“training zone.” The lower two numbers are recom-  
mended heart rates for fat burning; the higher number  
is the recommended heart rate for aerobic exercise.  
(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:  
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

A Warm-up

Training Zone Exercise  
to cool down. This will increase the flexibility of your  
muscles and will help to prevent post-exercise problems.  
After warming up, increase the intensity of your exer-  
cise until your pulse is in your training zone for 20 to  
60 minutes. (During the first few weeks of your exer-  
cise program, do not keep your pulse in your training  
zone for longer than 20 minutes.) Breathe regularly  
and deeply as you exercise—never hold your breath.  
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.  
A Cool-down  
The key to success is to make exercise a regular and  
enjoyable part of your everyday life.  
Finish each workout with 5 to 10 minutes of stretching  
SUGGESTED STRETCHES

Move slowly as you stretch—never bounce.  
1. Toe Touch Stretch

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 to-  
ward 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 ten-  
dons, bend your back leg as well. Stretches: Calves, achilles ten-  
dons, and ankles.

4. Quadriceps Stretch

one foot with your other hand. Bring your heel as close to your but-  
tocks as possible. Hold for 15 counts, then relax. Repeat 3 times  
for both legs. Stretches: Quadriceps and hip muscles.
