HOW TO USE THE EXERCISE CYCLE

HANDLEBAR OPERATION

The handlebars can be used in either the stationary
mode, for pedaling exercise only, or the dual-action
mode, for both upper-body and lower-body exercise.

STATIONARY MODE

To convert the
handlebars to
the stationary
mode, the Link
Arms (26) must
be disconnect­ed from the
pedals. Pull the
Link Arms out­ward against
the 17.5mm
Washers (56),
until the Link
Arms are free
of the Pedal
Bushings (25).

CAUTION: Be
careful not to
pinch your
fingers. Lift

the Link Arms
off the pedals.
Clip the Link Arms (26) onto the lock rod as shown in
drawing 2.

DUAL-ACTION MODE

To convert the handlebars to the dual-action mode, the
Link Arms must be connected to the pedals. Refer to
drawing 2 above. Lift the Link Arms (26) off the lock rod.

Next, refer to drawing 1 above. Pull the Link Arms (26)
outward against the tops of the 17.5mm Washers (56),
while pulling against the bottoms of the Washers with
your fingers. CAUTION: Be careful not to pinch your
fingers. Slide the Link Arms onto the Pedal Bushings
(25). It may be helpful to move the link arms up and
down slightly until they slide onto the Pedal Bushings.

CAUTION: Make sure that the Link Arms are on the
Pedal Bushings. If the Link Arms are not on the
Pedal Bushings, the Link Arms may slip off during
use, resulting in injury to the user.

SEAT ADJUSTMENT

Proper seat
height is impor­tant for effective
exercise. As you
pedal, there
should be a
slight bend in
your knees when
the pedals are in
the lowest posi­tion. To adjust
the Seat (48), dismount the exercise cycle, hold the
Seat, and remove the Seat Knob (52). Raise or lower
the Seat and insert the Seat Knob through the Frame
(1) and the Seat Post (42). Tighten the Seat Knob into
the welded nut on the Frame. CAUTION: Make sure

to insert the Seat Pin through the Seat Post; do
not insert the Seat Knob under the Seat Post.

ELECTRONIC MONITOR OPERATION

The electronic monitor offers five modes to provide
instant exercise feedback:

SpeedÑ
Displays
your pedal­ing speed, in
miles per
hour.

TimeÑ
Displays the
elapsed
time. Note:
Time will be
counted only
while you are pedaling. If you stop pedaling for ten
seconds or longer, the time mode will pause.

DistanceÑDisplays the total distance you have ped­aled, in miles.

CalorieÑDisplays the approximate number of Calories
you have burned.

ScanÑDisplays the speed, time, distance and calorie
modes in a repeating cycle.

Note: The electronic monitor requires two "AA" batter­ies (not included). See assembly step 3 on page 4 for
battery installation instructions.

Follow the steps below to use the electronic monitor:

1. To turn on the power, press the on/off button or
simply begin pedaling.

2. Select one of the five modes:

A. ScanÑ
When the
power is
turned on,
the scan
mode will
be select­ed auto­matically.
A mode
indicator
will appear
by the
word "SCAN." The speed, time, distance and calo­rie modes will all be displayed, for five seconds

each, in a repeating cycle. A second mode indica­tor will show which mode is currently displayed.

B. Speed, time, distance or calorieÑTo stop the
scan mode and select the speed, time, distance or
calorie mode for continuous display, repeatedly
press the mode button. Make sure that there is not
a mode indicator by the word ÒSCAN.Ó The modes
will be selected in the following order: speed, time,
distance, calorie, scan.

3. To reset the display, turn the power off and then on
again by pressing the on/off button twice.

4. When you are finished exercising, press the on/off
button to turn off the power. Note: If the pedals

are not moved and the buttons are not pressed
for four minutes, the power will turn off auto­matically in order to conserve the batteries.

8

Inspect and tighten all parts of the exercise cycle regu­larly. To clean the exercise cycle, use a damp cloth
and mild detergent. Never use abrasives or solvents;
keep liquid away from the console.

ELECTRONIC MONITOR

If the electronic monitor does not function properly, the
batteries should be replaced. Most problems are the
result of drained batteries. See assembly step 4 on
page 5 for battery installation instructions.

If the electronic monitor still does not function properly,
the sensor wire should be checked. See assembly step
4 on page 5. Slide the electronic monitor off the frame
and make sure that the sensor wire is plugged fully
into the wire on the electronic monitor.

TIGHTENING THE PEDALS

If the pedals become loose, tighten the pedal shafts
into the arms of the crank. Tighten the 1/2Ó Locknuts
onto the pedal shafts (see assembly step 7 on page 6).

ADJUSTING THE CHAIN

The exercise cycle features a precision chain that must
be kept properly lubricated and adjusted. Apply a few
drops of light multi-purpose oil to the chain every three
months. If the chain is too tight, the bearings may be
damaged; if the chain is too loose, the fan may be

damaged. If the chain causes excessive noise or slips
as you pedal, check the chain in the following way:

1. Carefully pry the Access Cover (14) off the right
side shield. Reach into the access hole and press
down on the chain. There should be no more

than 1 inch, and no less than 1/4 inch, of verti­cal movement in the center of the chain. If the

chain is properly adjusted, reattach the Access
Cover. If the chain needs to be adjusted, see step 2.

2. Pry the Access Cover (14) off the left side shield.
Loosen the M8 Washer Nuts (4). To tighten the
chain, turn the M6 Adjustment Nuts (8) clockwise;
to loosen the chain, turn the Adjust-ment Nuts
counterclockwise. Make sure that the fan is straight,
tighten the Fan Nuts and reattach the Access Covers.

The following general 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 recom­mended heart rates for fat burning, maximum fat burn­ing, and cardiovascular (aerobic) exercise.

To find the proper heart rate for you, first find your age
near the top of the chart (ages are rounded off to the
nearest ten years). Next, find the three numbers below
your age. 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 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 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.

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
system, 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 highest number in your training zone
as you exercise.

HOW TO MEASURE YOUR HEART RATE

To measure your heart rate, first exercise for at least
four minutes. Then, stop exercising and place two
fingers on your
wrist as shown.
Take a six­second 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.

WORKOUT GUIDELINES

Each workout should include three important parts: a
warm-up, training zone exercise, and a cool-down.

A Warm-up

Start each workout with 5 to 10 minutes of stretching
and light exercise. A proper warm-up increases your
body temperature, heart rate, and circulation in prepa­ration for strenuous exercise.

CONDITIONING GUIDELINES

WARNING: Before beginning this or any exercise
program, consult your physician. This is espe­cially important for individuals over the age of 35
or individuals with pre-existing health problems.

Note: Ò#Ó indicates a non-illustrated part. Specifications are subject to change without notice. See the back cover
of this manual for information about ordering replacement parts.

Training Zone Exercise

After warming up, increase the intensity of your
exercise until your heart rate is in your training zone
for 20 to 30 minutes. Note: During the first few weeks
of your exercise program, do not keep your heart rate
in your training zone for longer than 20 minutes.

A Cool-down

Finish each workout with 5 to 10 minutes of stretching.
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
between workouts. After a few months of regular
exercise, you may complete 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.
