HOW TO ADJUST THE REED SWITCH
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.
Next, locate the Reed Switch (49). Turn the Crank
(53) until the Magnet (4) is aligned with the Reed
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.
HOW TO ADJUST THE RESISTANCE STRAP
If there is not enough pedaling resistance when the
resistance knob is turned to the highest setting, the
Resistance Strap (15) may need to be adjusted. To
adjust the Resistance Strap, the left side shield must
first be removed. Refer to the instructions on page 7
and remove the left side shield.
Next, turn the
resistance knob to
the lowest setting.
Locate and open
the Strap Clamp
(38). Grip the end
of the Resistance
Strap (15) and
pull it up slightly.
While holding the
end of the
Resistance Strap,
fully close the Strap Clamp. Turn the Crank (53) for a
moment to make sure that there is not too much resistance. When the Resistance Strap is properly adjusted, reattach the left side shield and pedal.
HOW TO ADJUST THE DRIVE BELT
The exercise
cycle features a
precision drive
belt that must be
kept properly
adjusted. If the
belt causes
excessive noise
or slips as you
pedal, the belt
should be
checked. To do
this, the side shields must first be removed. Refer to
the instructions on page 7 and remove the left side
shield. Next, remove the right side shield in the same
way.
Press down on
the center of the
Drive Belt (14)
between the
front and rear
pulleys. There
should be from
1/4Ó to 1/2Ó of
movement in
the center of
the Belt. If the
Drive Belt (14) is
properly adjusted, reattach the side shields and pedals. 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) clockwise; 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.
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 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
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 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.
Burning Fat
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 energy. 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 number in your training zone as you exercise.
For maximum fat burning, adjust the intensity of your
exercise 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 the intensity of your exercise until
your heart rate is near the highest number in your
training zone.
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.)
WORKOUT GUIDELINES
Each workout should include the following three parts:
A warm-up, consisting of 5 to 10 minutes of stretching and light exercise. A proper warm-up increases
your body temperature, heart rate, and
circulation in preparation for exercise.
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.

# 1 UserÕs Manual
Training zone exercise, consisting of 20 to 30 minutes of exercising with your heart rate in your training
zone. (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, 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, plan 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. Caution: Be sure to progress at your own
pace and avoid overdoing it. Incorrect or excessive
training may result in injury to your health.
Remember, the key to success is make exercise a
regular and enjoyable part of your everyday life.
