OPERATION AND ADJUSTMENT
THE PERFORMANT LUBETM WALKING BELT
Your treadmill features a walking belt coated with
PERFORMANT LUBE TM, 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.
HOW TO PLUG IN THE POWER CORD
Your treadmill, like any other type of sophisticated
electronic equipment, can be seriouslydamaged 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).
Surge suppressors are sold at most hardware stores
and department stores. Use only a single-outlet surge
suppressor that is UL 1449 listed as a transient voltage
surge suppressor (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.
This product must be grounded. If it should malfunc-
tionor break down, groundingprovides a pathof least
resistance for electriccurrent to reduce the risk of elec-
tric shock. This productis equipped with a cord having
an equipment-groundingconductorand 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.
This productis for use on a nominal 120-volt circuit,
and has a grounding plugthat looks like the plug illus-
trated in drawing t below. A temporary adapter that
looks like the adapter illustrated in drawing 2 may be
used to connect the surge suppressorto a 2-pole
receptacle as shown in drawing 2 if a propedy
grounded outletis 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-colorad rigid ear, lug, or the like extending
from the adapter must be connected to a permanent
ground such as a properlygrounded 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.

CONDITIONING GUIDELINES
The following guidelines will help you to plan yourex-
ercise program. Remember--these are general guide-
lines only. For more detailed exercise information, ob-
tain a reputable book or consult your physician.
EXERCISEINTENSITY
Whether your goal is to bum 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 buming and aerobic exercise,
HEART RATETRAINING ZONES
Age 20 30 40 50 60 70 80
To findthe proper heart rate for you, first find your age
near the bottom of the chart (ages are rounded offto
the nearest ten years). Next, find the three numbers
above yourage. The three numbers define your "train-
ing zone."The lower two numbers are recommended
heart rates for fat burning; the higher number isthe
recommended heart rate for aerobic exercise.
To measure your heart rate during exercise, use the
pulse sensor on the console, if your heart rate is too
high or too low, adjust the speed and incline of the
treadmill.
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 caloriesfor en-
ergy. Onlyafterthe firstfew minutesdoesyour body
begin to use storedfat ca/odesfor energy, ffyour goal is
to bum fat, adjustthe speed and inclineofthe treadmill
untilyourheart rateis near the lowestnumberinyour
trainingzone. It may alsobe helpfulto use one ofthe
console'sFAT BURN programs(seepages10 and 11).
For maximum fat buming, adjustthe speed and incline
of the treadmill until your heart rate is near the middle
number in your training zone.
Aerobic Exercise
Ifyour goal is to strengthen yourcardiovascularsys-
tem, your exercise must be "aerobic." Aerobic exercise
isactivitythat requires large amountsof oxygen for
prolonged pedods of time. This increasesthe demand
on the heart to pump bloodto the muscles,and on the
lungsto oxygenate the blood. For aerobic exercise,
adjust the speed and inclineof the treadmill untilyour
heart rate is near the highestnumber in yourtraining
zone. It may also be helpfulto use one of the console's
AEROBIC programs (see pages 10 and 11).
WORKOUT GUIDELINES
Each workout should include the following three parts:
A Warm-up---Start each workoutwith 5 to 10 minutes
of stretchingand lightexercise. A properwarm-up in-
creases your bodytemperature, heart rateand circula-
tion in preparation for exercise.
Training Zone Exercis_After warming up, increase
the intensityof your exemise untilyour pulse is in your
training zone for 20 to 60 minutes.(During thefirst few
weeks of your exercise program,do not keep your
pulse inyour trainingzone forlongerthan 20 minutes.)
Breathe regularlyand deeply as youexercise--never
holdyour breath.
A Cool-down---Finish each workoutwith 5 to 10 min-
utes of stretchingto cool down.This will increase the
flexibility of yourmuscles and will help prevent post-ex-
ercise problems.
Exercise Frequency
To maintain or improve your condition,complete three
workoutseach week, with at least one day of rest be-
tween workouts. After a few months, you may com-
plete up tofive workoutseach week ifdesired. The key
to success isto make exercisea regularand enjoyable
part of your everyday life.
