TROUBLE-SHOOTING AND MAINTENANCE  
Inspect and tighten all parts of the exercise cycle regu- damaged. If the chain causes excessive noise or slips  
larly. To clean the exercise cycle, use a damp cloth  
and mild detergent. Never use abrasives or solvents;  
keep liquid away from the console.  
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 verti-  
cal 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.  
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  
4
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).  
8
ADJUSTING THE CHAIN  
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 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

CONDITIONING GUIDELINES  
The following general guidelines will help you to plan  
your exercise program. Remember that proper nutri-  
tion and adequate rest are essential for successful  
results.  
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.  
WARNING: Before beginning this or any exercise  
program, consult your physician. This is espe-  
cially important for individuals over the age of 35  
or individuals with pre-existing health problems.  
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.  
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.  
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 six-  
second heart-  
beat count, and  
multiply the  
result by 10 to  
find your heart  
rate. For  
example, if your  
six-second  
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.  
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.  
Fat Burning  
A Warm-up  
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  
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 prepa-  
ration for strenuous exercise.  
9
 
Training Zone Exercise  
Exercise Frequency  
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.  
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.  
A Cool-down  
The key to success is to make exercise a regular and  
enjoyable part of your everyday life.  
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.
