MAINTENANCE AND TROUBLE-SHOOTING
Inspect and tighten all parts of the PROFORM¨775s
regularly. The 775s can be cleaned with a soft, damp
cloth. To prevent damage to the console, keep liquids
away and keep the console out of direct sunlight.
BATTERY REPLACEMENT
If the console does not function properly, the batteries
should be replaced. To replace the batteries, refer to
assembly step 8 on page 6.
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 (6) must be
removed. First, using an adjustable wrench, turn the
Left Pedal (45) clockwise to remove the Pedal from
the left arm of the Crank (29).
Remove the four #8 x 5/8Ó Screws (22) from the bottom of the Left Side Shield (6). Grasp both Side
Shields at the top and gently pull them apart. Make
sure that the arm of the Crank (29) is in the position
shown in the drawing above. Hold the Left Side
Shield at the rear and pull it gently away from the
frame. Work the Left Side Shield forward off the arm
of the Crank and remove it.
Next, locate the
Reed Switch (13).
Loosen, but do not
remove, the #8 x
5/8Ó Screw (22).
Slide the Reed
Switch slightly
toward or away from
the Magnet (57) on
the pulley. Retighten
the Screw. Turn the Crank (29) for a moment. Repeat
until the console displays correct feedback. When the
Reed Switch is correctly adjusted, reattach the left
side shield.
HOW TO ADJUST THE DRIVE BELT
If the you can feel the pedals slip when you are exercising, especially when the resistance knob is turned
to the maximum setting, the Drive Belt (19) may need
to be adjusted. To adjust the Drive Belt, both side
shields must be removed. Refer to the instructions at
the left to remove the left side shield. Remove the
right side shield in the same manner.
Loosen the M8
Flanged Hex Nut
(36) on each side of
the Flywheel (42).
Tighten the M6 Nut
(39) on each M6
Eyebolt (37) until the
Drive Belt (19) is
tight. Be sure that
you tighten each
M6 Nut an equal
amount. Once the
Drive Belt is tight,
tighten the M8 Flanged Hex Nuts (36). Reattach the
side shields.
CRANK ADJUSTMENT
If the arms of the
Crank (29) become
loose, they should
be tightened in order
to prevent excessive
wear. Loosen the
Crank Nut (35) on
the left arm of the
Crank. Place the
end of a standard
screwdriver in one
of the slots in the
Slotted Bearing Nut
(33). Lightly tap the screwdriver with a hammer to turn
the Slotted Bearing Nut counterclockwise until the
arms are no longer loose. Do not overtighten the
Slotted Bearing Nut. When the Slotted Bearing Nut
is properly tightened, tighten the Crank Nut.
STORAGE
When storing the exercise bike, remove the batteries
from the console. Keep the exercise bike in a clean,
dry location, away from moisture and dust.

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
at the bottom of the chart (ages are rounded off to the
nearest ten years). Next, find the three numbers
above your age. The three numbers are your Òtraining
zone.Ó The smallest number is the recommended
heart rate for fat burning; the middle number is the
heart rate for maximum fat burning; the largest
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 smallest
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 largest 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
important parts: A warm-up, consisting of 5 to 10 minutes of stretching and light exercise. A proper warmup increases your body temperature, heart rate, and
circulation in preparation for exercise. 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 plan 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 to make exercise a
regular and enjoyable part of your everyday life.
WARNING: Before beginning this or any exercise program, consult your physician. This is
especially important for persons over age 35
or persons with pre-existing health problems.
