HOW TO USE THE AIR WALKER
EXERCISING ON THE AIR WALKER
Make sure that the lock knob is tightened into the left
leg and link plate (see assembly step 2 on page 4).
Adjust the resistance to a high setting, hold the
handles, and step onto the pedals. The proper form
for exercising on the AIR WALKER is similar to the
motion of walkingÑmove one leg forward as you
move the other leg back.
For a full body workout, hold the handles as you walk
and move your arms and legs in motion with the
handles and pedals. To vary the effect of the exercise
on your muscles, bend your legs slightly instead of
keeping them straight.
For a lower body workout, rest your hands on the
crossbar cover for balance as you move the pedals.
RESISTANCE ADJUSTMENT
To vary the intensity of your workout, the resistance of
the AIR WALKER can be adjusted. To change the
resistance, turn the resistance dials on the resistance
cylinders. There are twelve different resistance levels.
Arrows on the resistance cylinders will show which
resistance level is selected. Select the same resis-
tance level on both cylinders.
CAUTION: The resistance cylinders become very
hot during use. Allow the resistance cylinders to
cool before touching them. When adjusting the
resistance, touch only the resistance dials.
ELECTRONIC MONITOR MODES
The simple-to-operate electronic monitor offers
five different modes to provide instant exercise
feedback. The five modes are described below:
SpeedÑDisplays the number of repetitions you are
performing per minute.
TimeÑDisplays the length of time you have exer-
cised. Note: If you stop exercising for ten seconds or
longer, the time mode will pause until you resume.
DistanceÑDisplays the total number of repetitions
you have completed, up to Ò999.Ó The display will then
reset to Ò0Ó and continue counting.
CaloriesÑDisplays the approximate number of
Calories you have burned. Note: If the resistance is
near the highest or lowest setting, the actual number
of Calories you have burned will be slightly higher or
lower than the number displayed.
ScanÑDisplays the speed, time, distance, and calo-
ries modes, for approximately 5 seconds each,
in a repeating cycle.

OPERATING THE ELECTRONIC MONITOR
1. To turn on the power, press the on/reset button or
simply begin exercising on the AIR WALKER. The
entire display will appear for two seconds. The
electronic monitor will then be ready for operation.
2. Select one of the five modes:
Scan modeÑWhen the power is turned on, the
scan mode will be selected automatically. The
scan mode
can also be
selected by
repeatedly
pressing the
mode but-
ton. One
mode indi-
cator will
show that
the scan
mode has been selected, and a second mode indi-
cator will show which mode is currently displayed.
Speed, time, distance, or calories modeÑ
These modes can be individually selected by
repeatedly
pressing
the mode
button. The
mode indi-
cators will
show which
mode has
been
selected.
(Make sure
that the scan mode is not selected.) The modes
will be selected in the following order: speed, time,
distance, calories, scan.
3. The monitor has an auto-off feature to turn off
the power. If the pedals are not moved and the
monitor buttons are not pressed for four minutes,
the power will turn off automatically in order to
conserve the batteries.
To reset the LCD display, press the on/reset button.

Inspect and tighten all parts of the AIR WALKER reg-
ularly. Replace any worn parts immediately.
The AIR WALKER can be cleaned with a soft, damp
cloth. Keep liquids away from the electronic monitor.
Keep the monitor out of direct sunlight or the display
may be damaged. Remove the batteries when storing
the AIR WALKER.
REPLACING THE BATTERIES
If the display of the electronic monitor becomes dim,
or if the monitor does not function properly, the batter-
ies should be replaced. To replace the batteries, first
lift the monitor from the crossbar cover (see assembly
step 4 on page 5). Make sure that the reed switch
wire is fully connected to the wire on the monitor. To
replace the batteries, refer to assembly step 3 on
page 4.
HOW TO FOLD THE AIR WALKER FOR STORAGE
When the AIR WALKER is not in use, it can be folded
for storage. To fold the AIR WALKER, first remove the
lock knob from the left leg. Next, move to the front of
the AIR WALKER and place one foot on the round
tube. Firmly grasp the frame with your hands in the
locations indicated below. While holding the round
tube stationary with your foot, pull the top of the AIR
WALKER toward you until the uprights fold against
the frame. Place the AIR WALKER in a location
where it cannot fall.

CONDITIONING GUIDELINES
The following guidelines will help you to plan your
exercise program. Remember that proper nutrition and
adequate rest are essential for successful results.
EXERCISE INTENSITY
Whether your goal is to burn fat or 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, maximum fat burn-
ing, and cardiovascular (aerobic) exercise.
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, look above your age and
find the three numbers in light grey boxes. The three
numbers are your Òtraining zone.Ó The lowest number
is the recommended heart rate for fat burning; the
middle number is the recommended heart rate for
maximum fat burning; the highest number is the rec-
ommended heart rate for aerobic exercise.
Fat Burning
To burn fat effectively, you must exercise at a relative-
ly low intensity level for a sustained period of time.
During the first few minutes of exercise, your body
uses easily accessible carbohydrate calories for ener-
gy. Only after the first few minutes of exercise does
your body begin to use stored fat calories for energy. If
your goal is to burn fat, adjust your pace until your
heart rate is near the lowest number in your training
zone as you exercise. It may also be helpful to set the
dials on the resistance cylinders at level 1, 2, 3, or 4.
For maximum fat burning, adjust your pace until your
heart rate is near the middle number in your training
zone as you exercise.
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 your pace until your heart rate is near the high-
est number in your training zone. It may also be help-
ful to set the dials on the resistance cylinders at level
5, 6, 7, or 8.
Strength Training
To strengthen and tone your muscles, you must exer-
cise your muscles at a moderate to high percentage of
their capacity. Set the dials on the resistance cylinders
at level 9, 10, 11, or 12.
HOW TO MEASURE YOUR HEART RATE
To measure your heart rate, first exercise for at least
four minutes.
Then, stop
exercising and
place two fin-
gers on your
wrist as
shown. Take a
six-second
heartbeat
count, and
multiply the
result by 10 to
find your heart
rate. For example, if your six-second heartbeat count
is 14, your heart rate is 140 beats per minute. (A six-
second count is used because your heart rate will
drop rapidly when you stop exercising.)
Adjust the intensity of your exercise until your heart
rate is at the desired level. You can adjust the intensity
of your exercise by adjusting the resistance or by
changing your pace.
WARNING: Before beginning this or any
exercise program, consult your physician.
This is especially important for persons over
the age of 35 or persons with pre-existing
health problems.

Note: Ò#Ó refers to a non-illustrated part. Specifications are subject to change without notice. See the back cover
of this manual for information about ordering replacement parts.
WORKOUT GUIDELINES
Each workout should include the following three parts:
A warm-up, lasting 5 to 10 minutes. Begin with slow,
controlled stretches, and progress to more rhythmic
stretches to increase the body temperature, heart rate,
and circulation in preparation for strenuous exercise.
Training zone exercise, consisting of 20 to 30 min-
utes of exercising with your heart rate in your training
zone.
A cool-down, with 5 to 10 minutes of stretching.
Thorough stretching helps to offset problems caused
when you stop exercising suddenly. Stretching for
increased flexibility is also most effective after exercis-
ing. A proper cool-down should leave you relaxed and
comfortably tired.
EXERCISE FREQUENCY
To maintain or improve your condition, plan three
workouts each week, with at least one day of rest
between workouts. After a few months of regular exer-
cise, you may complete up to five workouts each
week, if desired.
Remember, the key to success is make exercise a
regular and enjoyable part of your everyday life.
