STORAGE AND TROUBLE-SHOOTING  
Inspect and tighten all parts of the exercise cycle  
regularly. Replace any worn parts immediately.  
HOW TO STORE THE EXERCISE CYCLE  
When the exercise  
cycle is not in use,  
it can be folded for  
compact storage.  
Remove the Spring  
Clip (52) and then  
pull out the ÒLÓ Pin  
(56). Next, fold the  
exercise cycle by  
bringing the seat  
and handlebars  
toward one anoth-  
er. Store the exer-  
cise cycle indoors,  
away from mois-  
ture and dust.  
The exercise cycle can be cleaned with a soft, damp  
cloth. Avoid spilling liquid on the console. Keep the  
console out of direct sunlight or the display may be  
damaged. Remove the batteries when storing the  
exercise cycle.  
BATTERY REPLACEMENT  
If the console does not function properly, the batteries  
should be replaced. See assembly step 5 on page 5.  
In addition, make sure that the console wire is con-  
nected to the reed switch wire.

fully close the Strap Clamp. Turn the Crank (53) for a  
moment to make sure that there is not too much resis-  
tance. When the Resistance Strap is properly adjust-  
ed, reattach the left side shield and pedal.  
If the console does not display correct feedback, the  
reed switch should be adjusted. In order to adjust the  
reed switch, the Left Side Shield (10) must be  
removed. Using an adjustable wrench, turn the Left  
Pedal (8) clockwise and remove it from the Crank  
(53). Remove the three M4 x 12mm Screws (40) and  
the two M4 x 16mm Screws (7) from the Left Side  
Shield. Make sure that the arm of the Crank is in the  
position shown in the drawing above. Carefully slide  
the Left Side Shield forward off the arm of the Crank  
and remove it.  
HOW TO ADJUST THE DRIVE BELT

Switch. Loosen but do not remove the M4 x 16mm  
Screw (7). Slide the Reed Switch slightly closer to or  
away from the Magnet. Retighten the Screw. Turn the  
Crank for a moment. Repeat until the console displays  
correct feedback. When the Reed Switch is correctly  
adjusted, reattach the left side shield and pedal.

Drive Belt (14) is  
properly adjusted, reattach the side shields and ped-  
als. If the Belt needs to be adjusted, loosen the Nylon  
Locknut (54) on the left side of the Flywheel (29). To  
tighten the Belt, turn the Adjustment Nut (30) clock-  
wise; to loosen the Belt, turn the Adjustment Nut  
counterclockwise. Make sure that the Flywheel is  
straight and tighten the Nylon Locknut (54). Reattach the  
side shields and pedals.

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.  
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.  
WARNING:  
Before beginning this  
or any exercise program, consult your physi-  
cian. This is especially important for persons  
over the age of 35 or persons with pre-exist-  
ing health problems.  
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  
EXERCISE INTENSITY  
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.  
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 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.)  
To find the proper heart rate for you, first find your age  
on either side of the chart (ages are rounded off to the  
nearest ten years). Next, find the three numbers to  
the side of your age. The three numbers are your  
Òtraining zone.Ó The lowest number is the recommend-  
ed 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.  
WORKOUT GUIDELINES  
Each workout should include the following three parts:  
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.  
Burning Fat  
To burn fat effectively, you must exercise at a rela-  
tively low intensity level for a sustained period of time.  
9
 
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.)  
EXERCISE FREQUENCY  
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  
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.  
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.  
Remember, the key to success is make exercise a  
regular and enjoyable part of your everyday life.
