HOW TO LOWER THE TREADMILL FOR USE
1. Hold the upper end of the treadmill with your right hand as
shown. Using your left thumb, press the storage latch and
hold it. Pivot the treadmill until the frame and foot rail are
past the storage latch.
2.  Hold the treadmill firmly with both hands, and lower the
treadmill to the floor. To decrease the possibility of in-
jury, bend your legs and keep your back straight. HOW TO MOVE THE TREADMILL 
Before moving the treadmill, convert the treadmill to the stor-
age position as described above. Make sure that the stor-
age latch is closed fully over the catch. 
1.  Hold the upper ends of the handrails. Place one foot on
the base as shown.
2.  Tilt the treadmill back until it rolls freely on the front
wheels. Carefully move the treadmill to the desired loca-
tion. Never move the treadmill without tipping it back,
or the base pads may come off. To reduce the risk of
injury, use extreme caution while moving the tread-
mill. Do not move the treadmill over an uneven 
surface.
3.  Place one foot on the base, and carefully lower the tread-
mill until it is resting in the storage position.

							TROUBLE-SHOOTING
Most treadmill problems can be solved by following the simple steps below. Find the symptom that 
applies, and follow the steps listed. If further assistance is needed, call our toll-free HELPLINE at 
1-800-736-6879, Monday through Saturday, 7 a.m. until 7 p.m. Central Time (excluding holidays). 
1. SYMPTOM: THE POWER DOES NOT TURN ON
a. Make sure that the power cord is plugged into a surge suppressor, and that the surge suppressor is plugged
into a properly grounded outlet (see page 7). 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.  
b. After the power cord has been plugged in, make sure that the key is fully inserted into the console. See step
1 on page 9.
c. Check the circuit breaker located on the treadmill near the
power cord. If the switch protrudes as shown, the circuit
breaker has tripped. To reset the circuit breaker, wait for five
minutes and then press the switch back in. 
2. SYMPTOM: THE POWER TURNS OFF DURING USE
a. Check the circuit breaker located on the treadmill frame near the power cord (see 1. c. above). If the circuit
breaker has tripped, wait for five minutes and then press the switch back in.
b. Make sure that the power cord is plugged in.
c. Remove the key from the console. Reinsert the key fully into the console. See step 1 on page 9.
d. If the treadmill still will not run, please call our toll-free HELPLINE.
3. SYMPTOM: THE DISPLAYS OF THE CONSOLE DO NOT FUNCTION PROPERLY
a. Check the batteries in the console. See BATTERY INSTALLATION on page 8. Most problems are the result
of drained batteries. 
b. Remove the six screws from the hood. Carefully remove the
hood. Locate the Reed Switch (44) and the Magnet (45) on the
left side of the Pulley (50). Turn the Pulley until the Magnet is
aligned with the Reed Switch. Make sure that the gap between
the Magnet and the Reed Switch is about 1/8Ó.If necessary,
loosen the Screw (89) and move the Reed Switch slightly.
Retighten the Screw. Re-attach the hood, and run the treadmill
for a few minutes to check for a correct speed reading.
4. SYMPTOM: THE INCLINE SYSTEM STICKS
a. Raise the treadmill to the storage position. See HOW TO FOLD THE TREADMILL FOR STORAGE on page
10. Pivot the incline leg several times to break in the incline system.

							5. SYMPTOM: THE WALKING BELT SLOWS WHEN WALKED ON
a. Use only a UL-listed surge protector, rated at 15 amps, with a 14-gauge cord of five feet or less in length. 
b. If the walking belt is overtightened, treadmill performance may
decrease and the walking belt may be permanently damaged.
Remove the key and UNPLUG THE POWER CORD. Using the
allen wrench, turn both rear roller adjustment bolts counterclock-
wise, 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. The center of the walking belt
should just touch the walking platform. Be careful to keep the
walking belt centered. Plug in the power cord, insert the key and
run the treadmill for a few minutes. Repeat until the walking belt
is properly tightened.
c. If the walking belt still slows when walked on, please call our toll-free HELPLINE.
6. SYMPTOM: THE WALKING BELT IS OFF-CENTER WHEN WALKED ON
a. If the walking belt has shifted to the left, first remove the key
and UNPLUG THE POWER CORD. Using the allen wrench,
turn the left rear roller adjustment bolt clockwise, and the right
bolt counterclockwise, 1/4 of a turn each. Be careful not to over-
tighten 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 has shifted to the right, first remove the
key and UNPLUG THE POWER CORD. Using the allen wrench,
turn the left rear roller adjustment bolt counterclockwise, and the
right bolt clockwise, 1/4 of a turn each. Be careful not to over-
tighten 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.
c. If the walking belt slips when walked on, first remove the key
and UNPLUG THE POWER CORD. Using the allen wrench,
turn both rear roller adjustment bolts clockwise, 1/4 of a turn.
When the walking belt is correctly 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, insert the key and run the treadmill for a few
minutes. Repeat until the walking belt is properly tightened.
7. SYMPTOM: ONE OF THE UPPER BODY ARMS SQUEAKS DURING USE
a. Correcting this problem requires a small amount of white marine grease, available at most hardware stores. 
Turn the Resistance Knob (101) counterclockwise until it can be
removed. Remove the Resistance Cone (100) and the Upper
Body Arm (102), along with the 3/8Ó Washers (95), Spring
Washer (97), Thrust Washers (96), and Thrust Bearing (98).
(Note: If the Resistance Sleeve [99] comes out of the
Resistance Bracket [94], press it back in.) Apply a thin layerof
white marine grease to the outer surface of the Resistance Cone
(100). Reattach all parts in the order shown at the right.

							CONDITIONING GUIDELINES
The following guidelines will help you to plan your ex-
ercise program. RememberÑthese are general guide-
lines only. For more detailed exercise information, ob-
tain 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. (This chart is also found on the console.) 
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
Òtraining zone.Ó The lower two numbers are recom-
mended heart rates for fat burning; the higher number
is the recommended heart rate for aerobic exercise.
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 energy. Only after
the first few minutes does your body begin to use
stored fat caloriesfor energy. If your goal is to burn fat,
adjust the speed and incline of the treadmill until your
heart rate is near one of the lower two numbers in yourtraining zone. It may also be helpful to set the speed
control on the console to FAT BURN to help you main-
tain the proper intensity level. (See page 9.)
Aerobic Exercise
If your goal is to strengthen your cardiovascular sys-
tem, your exercise must be Òaerobic.Ó 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.)  
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 ex-
ercising 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. (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 in-
cline of the treadmill accordingly.
WORKOUT GUIDELINES
A well-rounded workout includes the following three
important parts:
A Warm-up
Start each workout with 5 to 10 minutes of stretching
and light exercise (see SUGGESTED STRETCHES on
page 15). A proper warm-up increases your body 
temperature, heart rate, and circulation in preparation
for exercise. 
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.
14 
						

							Training Zone Exercise
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 exerciseÑnever hold your breath. 
A Cool-down
Finish each workout with 5 to 10 minutes of stretchingto cool down. This will increase the flexibility of your
muscles and will help to prevent post-exercise problems.
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.
SUGGESTED STRETCHES
The correct form for several basic stretches is shown in the
drawings below. Move slowly as you stretchÑnever bounce.
1. Toe Touch Stretch
Stand with your knees bent slightly and slowly bend forward
from 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
toward 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 tendons, bend your back leg as well. Stretches:
Calves, achilles tendons, and ankles.
4. Quadriceps Stretch
With one hand against a wall for balance, reach back and
grasp one foot with your other hand. Bring your heel as close
to your buttocks as possible. Hold for 15 counts, then relax.
Repeat 3 times for both legs. Stretches: Quadriceps and hip
muscles.
5. Inner Thigh Stretch
Sit with the soles of your feet together and your knees outward.
Pull your feet toward your groin area as far as possible. Hold
for 15 counts, then relax. Repeat 3 times. Stretches:
Quadriceps and hip muscles.
