IMPORTANT PRECAUTIONS
WARNING: To reduce the risk of serious injury, read the following important precautions before
using the stepper.
1. Read all instructions in this manual before
using the stepper. Use the stepper only as
described.
9. The resistance cylinders may become hot
after a period of use. Allow the cylinders to
cool before touching them
2. It is the responsibility of the owner to ensure
that all users of the stepper are adequately
informed of all precautions.
10. Always keep your back straight when using
the stepper. Do not arch your back.
11. If you feel pain or dizziness at any time
while exercising, stop immediately and
begin cooling down.
3. Use the stepper indoors, away from mois-
ture and dust. Place the stepper on a level
surface, with a mat beneath it to protect the
floor or carpet from damage.
12. The stepper is intended for in-home use
only. Do not use the stepper in a commer-
cial, rental, or institutional setting.
4. Inspect and tighten all parts regularly.
Replace any worn parts immediately.
13. The decal shown below has been placed on
the stepper. If the decal is missing, or if it is
not legible, call our toll-free HELPLINE to
order a free replacement decal.
5. Keep children under the age of 12 and pets
away from the stepper at all times.
6. The stepper should not be used by persons
weighing more than 250 pounds.

WARNING
7. Wear appropriate clothing when exercising;
do not wear loose clothing that could become
caught on the stepper. Always wear athletic
shoes for foot protection.

injury.
• Read user’s manual
and follow all warnings
and operating instruc-
tions prior to use.

HOW TO USE THE STEPPER
DESCRIPTION OF THE CONSOLE
Follow the steps below to operate the console.
The console features five modes that provide instant
exercise feedback during your workouts. The modes
are described below.
1. To turn on the power, press the on/reset button or
simply begin stepping. When the power is turned
on, the entire display will appear for two seconds.
The console will then be ready for operation.
2. Select one of the five modes:

scan mode is not selected.
¥ Fat CalorieÑDisplays the approximate number of fat

page 9.)
¥ CalorieÑDisplays the approximate number of calo-
ries you have burned. This number includes both fat
calories and carbohydrate calories.
3. To reset the display, press the on/reset button.
¥ ScanÑDisplays the reps per minute, distance, time,
fat calorie and calorie modes, for 5 seconds each, in
a repeating cycle.
4. To turn off the power, simply wait for about four
minutes. Note: The monitor has an Òauto-offÓ
feature. If the pedals are not moved and the
monitor buttons are not pressed for four min-
utes, the power will turn off automatically in
order to conserve the batteries.
HOW TO OPERATE THE CONSOLE
Before the console can be operated, two ÒAAÓ
batteries must be installed. If you have not installed
batteries, see assembly step 8 on page 6.

HOW TO EXERCISE ON THE STEPPER
HOW TO ADJUST THE RESISTANCE
Place the stepper on a level surface and place a mat
under the stepper. (The stepper features precision
hydraulic cylinders. However, there is a possibility of
slight oil leakage due to the nature of hydraulic cylin-
ders.)
To change the stepping resistance, first lift the Right
and Left Pedal Legs (6, 7) off the hooks at the lower
ends of the Resistance Cylinders (9). Move the hooks
to different slots under the Pedal Legs. Make sure
that the hooks are fully inserted into the slots in
the same position under both Pedal Legs. The far-
ther the hooks are moved from the Upright (1), the
greater the resistance will be.
Hold the handlebars and step onto the pedals. Begin
stepping, alternately depressing the right and left ped-
als with a smooth, continuous motion. Because the
pedals move independently of each other, you must
maintain a continuous motion or both pedals will sink
to the floor. Change the height of your step or the
stepping pace until you can comfortably maintain a
continuous motion.

As you step, you can exercise your upper leg mus-
cles by keeping your feet flat on the pedals. To focus
on your calf muscles, rise on your toes as you step.
Stand erect or lean forward slightly as you exercise,
always keeping your back straight in order to avoid
injury.

play becomes faint, the batteries should be replaced.

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.
For maximum fat burning, adjust the intensity of your
exercise until your heart rate is near the middle num-
ber in your training zone as you exercise.
Aerobic Exercise
WARNING: Before beginning this or any exer-
cise program, consult your physician. This is
especially important for persons over the age
of 35 or persons with pre-existing health
problems.
If your goal is to strengthen your cardiovascular sys-
tem, your exercise must be Òaerobic.Ó Aerobic exer-
cise 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 intensity of your exercise until
your heart rate is near the highest number in your
training zone.
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, maximum fat
burning, and cardiovascular (aerobic) exercise.
HOW TO MEASURE YOUR HEART RATE
To measure your
heart rate, first exer-
cise for at least four
minutes. Then, stop
exercising and place
two fingers on your
wrist as shown. Take
a six-second heart-
beat count, and multi-
ply 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.)
WORKOUT GUIDELINES
Each workout should include the following three parts:
To find the proper heart rate for you, first find your age
at the top of the chart (ages are rounded off to the
nearest ten years). Next, find the three numbers
below of your age. The three numbers are your Òtrain-
ing zone.Ó The lowest number is the recommended
heart rate for fat burning; the middle number is the
heart rate for maximum fat burning; the highest
number is the heart rate for aerobic exercise.
A warm-up, consisting of 5 to 10 minutes of stretch-
ing and light exercise. A proper warm-up increases
your body temperature, heart rate, and circulation in
preparation for exercise.
Training zone exercise, consisting of 20 to 30 min-
utes of exercising with your heart rate in your training
zone. (During the first few weeks of your exercise pro-
gram, do not keep your heart rate in your training
zone for longer than 20 minutes.)
Burning Fat
To burn fat effectively, you must exercise at a rela-
tively 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 the intensity of your
exercise until your heart rate is near the lowest num-
ber in your training zone as you exercise.
A cool-down, with 5 to 10 minutes of stretching. This
will increase the flexibility of your muscles and will
help to prevent post-exercise problems.

desired. Caution: Be sure to progress at your own
pace and avoid overdoing it. Incorrect or excessive
training may result in injury to your health.
To maintain or improve your condition, plan three work-
outs each week, with at least one day of rest between
workouts. After a few months of regular exercise, you
may complete up to five workouts each week, if
Remember, the key to success is make exercise a
regular and enjoyable part of your everyday life.
