Inspect and tighten all parts of the LIFESTYLER
¨
DT1000 regularly. Replace worn parts immediately.
The DT1000 can be cleaned with a soft, damp cloth.
Keep liquid away from the electronic monitor. Keep
the monitor out of direct sunlight or the display may
be damaged. Remove the batteries when storing the
DT1000.
ELECTRONIC MONITOR TROUBLE-SHOOTING
If the electronic monitor does not function properly,
the batteries should be replaced. See assembly step
5 on page 5 for instructions. In addition, make sure
that the sensor wire is connected to the wire on the
monitor. See assembly step 6 on page 5.
If the electronic monitor displays incorrect information,
the reed switch should be checked. First, remove the
pedal and the side shield from one side of the exercise bike.
Next, refer to
the drawing
at the right
and locate
the reed
switch. Turn
the sprocket
until the
magnet on
the sprocket
is as close
as possible to the reed switch. Loosen the screw in
the reed switch, move the reed switch slightly closer to
the magnet, and tighten the screw. Make sure that
the magnet will not hit the reed switch when the
sprocket turns. Repeat until the monitor displays
correct information.
HOW TO TIGHTEN THE PEDALS
If the pedals become loose, refer to assembly step 8
on page 5. Tighten the pedal axles into the arms of
the crank. Tighten the 1/2" locknuts on the pedal axles.
HOW TO ADJUST THE CHAIN
The exercise bike features a precision chain that must
be kept properly lubricated. Apply a few drops of light
multi-purpose oil to the chain every three months.
In addition, the chain must be kept properly adjusted.
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 manner:
1. Remove the fan guards from the front of the exercise bike. Remove the pedal and the side shield
from one side of the exercise bike.
2. Press down on the center of the chain. There
should be between 1/4Ó and 1Ó of vertical
movement in the center of the chain. If the
chain is properly adjusted, reattach the side shield,
pedal, and fan guards. If the chain needs to be
adjusted, see step 3.
3. Loosen both axle nuts. To tighten the chain, turn
the adjustment nuts clockwise; to loosen the chain,
turn the adjustment nuts counterclockwise. Make
sure that the fan is straight and tighten the axle nuts.
Reattach the side shield, pedal, and fan guards.

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.

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. (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.
