ASSEMBLY
To hire an authorized service technician to assemble the treadmill, call toll-free 1-800-445-2480.
Assembly requires two persons. Set the treadmill in a cleared area and remove all packing materials. Do not
dispose of the packing materials until assembly is completed. Note: The underside of the treadmill walking belt is
coated with high-performance lubricant. During shipping, a small amount of lubricant may be transferred to the top of
the walking belt or the shipping carton. This is a normal condition and does not affect treadmill performance. If there
is lubricant on top of the walking belt, simply wipe off the lubricant with a soft cloth and a mild, non-abrasive cleaner.

OPERATION AND ADJUSTMENT
THE PRE-LUBRICATED WALKING BELT
tric shock. This product is equipped with a cord having
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 high-
performance lubricant. IMPORTANT: Never apply sil-
icone spray or other substances to the walking
belt or the walking platform. Such substances will
deteriorate the walking belt and cause excessive
wear.
HOW TO PLUG IN THE POWER CORD
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.
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 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 PROFORM dealer or call the toll-free
telephone number on the front cover of this man-
ual and order part number 146148, or see your local
electronics store.

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 moni-
toring light on the surge suppressor to indicate
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, accelerate 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-

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
uses easily accessible carbohydrate calories for en-
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-up—Start 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 Exercise—After 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 exercise—never
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-down—Finish 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. If your heart rate is too high or too low,
adjust the speed and incline of the treadmill.
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
