After the power is turned on, move the speed control to the "Reset" position. (As a safety
feature, each time the power is turned on, the speed control must be moved to the
"Reset" position before the walking belt can be started.)
Move the speed control slowly forward until the walking belt begins to move at slow speed.
Hold the handrail firmly and step onto the walking belt,
Move the speed control slowly forward or backward until the belt is moving at the desired
speed. (The speed can be adjusted at any time as you exercise on the treadmill.)

INCLINE ADJUSTMENT
To vary the level of exercise difficulty, the incline of the treadmill can be changed using either the
manual mode or the programmable mode.
MANUAL MODE
The manual incline control is located on the right side of the
console. To increase the incline of the treadmill, press the
front of the control until the desired angle is reached. To
decrease the incline of the treadmill, press the back of the
control until the desired angle is reached.
There is a bubble located above the incline lever on the console. The bubble measures the incline
of the treadmill.
PROGRAMMABLE MODE
The programmable mode allows you to set the length of time that you plan to exercise, and pro-
gram eight incline settings. The treadmill computer then controls the. incline of the treadmill
automatically for the set length of time.
1. Set the timer for the length of time that you plan to exercise, from 5 to 40 minutes.
2. Set the eight auto incline controls to the desired incline levels.
.Press the program "START" key. The indicator below the first auto incline control will light
and the treadmill will adjust to the first incline setting. After one-eighth of the total set time has
elapsed, the indicator below the second auto incline control will light and the treadmill will ad-
just to the secQnd incline setting. (The computer will sequentially activate all eight auto incline
controls regardless of the length of time set.) When the total time has elapsed, the treadmill
will remain at the last incline setting and revert to the manual mode.
Note: The auto incline controls can be changed while the program is running if desired. Pressing
the manual incline control at any time while the program is running will stop the program
and cause the treadmill to revert to the manual mode.
IMPORTANT: This treadmill has been designed to remain operational if the electronic monitor or
programmable mode malfunction. Even with the monitor removed, the power, speed and
manual incline mode can be controlled as described above.
ELECTRONIC MONITOR OPERATION
Refer to the ELECTRONIC MONITOR OPERATION GUIDE accompanying this manual for
operating instructions.

MAINTENANCE AND STORAGE
Check all parts periodically to ensure that they are tightened securely. Outside surfaces of the
treadmill can be cleaned using a damp cloth and mild, non-abrasive detergent.
WALKING BELT ADJUSTMENT
To prevent damage to the Walking Belt, always keep the Belt centered during operation. Stand
beside the treadmill and turn the treadmill on at medium speed. Observe the spaces between the
edges of the Walking Belt and the Foot Rails. If the Belt is closer to one Foot Rail than the other,
center the Belt in the following manner:
1. Locate the Belt Adjustment Bolts and the Adjustment Tool. Caution: Keep your hands away
from the moving Walking Belt or serious Injury could result.
2. A. If the Walking Belt has shifted to the left side:
Turn the left Adjustment Bolt clockwise and the
right Adjustment Bolt counterclockwise, 118 of a
turn at a time, until the Belt moves to the center.
B, If the Walking Belt has shifted to the right side:
Turn the left Adjustment Bolt counterclockwise and
the right Adjustment Bolt clockwise. 118 of a turn
at a time, until the Belt moves to the center.
If the Walking Belt slips during operation, the tension
should be adjusted. Turn both Adjustment Bolts clockwise
an equal amount until the Belt no longer slips. Be careful
to keep the Belt centered. Do not over-tighten the Bolts.
Overtightening may stretch the Belt, cause excessive Roller
noise and reduce Motor performance.
To check for proper Walking Belt tightness, unplug the
Power Cord and lift the sides of the Belt. You should be able
to lift both sides approximately 2-3 inches off of the Walking
Platform. The center of the Belt should remain just at the
surface of the platform, causing the Belt to bow.

The Adjustment Tool can be stored on one of the Roller
Brackets using the adhesive Tool Clamp included.

SILICONE APPLICATION
To maintain the low-friction quality of the Walking Belt and
reduce treadmill wear, anon-oil, non-petroleum base
silicone lubricant should be applied generously to the
Walking Platform. (Silicone lubricant is available at most
hardware and automotive stores.) It is very Important to
apply silicone lubricant before initial use of the treadmill.
Lubricant should also be applied after every 10 hours of use
or whenever a decrease in performance is noticed. Unplug
the Power Cord, lift each side of the Walking Belt and apply
the lubricant generously to the area indicated in the drawing.
CIRCUIT BREAKER
If the treadmill stops or will not start, check the Circuit
Breaker located on the front of the Frame near the Power
Cord. The Circuit Breaker is designed to protect the
electrical system. If the Circuit Breaker has tripped, the
switch will protrude as shown. To reset the Circuit Breaker,
allow the treadmill to cool for a few minutes and then push
the switch back in. Tripped Operational

CONDITIONING GUIDELINES
The following guidelines will help you to plan and regulate your personal fitness program.
However, before beginning this or any exercise program, consult your physician. Remember
that adequate rest and good nutrition are also essential to the success of any fitness program.
EXERCISE INTENSITY
To maximize health benefits from exercising, your level of exertion must exceed mild demands
while falling short of causing breathlessness and fatigue. The proper level of exertion can be
determined using the heart rate as a guide. For effective aerobic exercise the heart rate must be
maintained at a level between 70% and 85% of your maximum heart rate. This is your "Training
Zone." 11

You can determine your Training Zone by consulting the table below. Training Zones are given for
both conditioned and unconditioned persons. Use the column that is appropriate for you.

During the first few weeks of your exercise program you should keep your heart rate near the low
end of your Training Zone. Over the course of a few months, gradually increase your heart rate
until you reach the high end of your Training Zone. As your condition improves, a greater
workload will be required in order to raise your heart rate to your Training Zone.
You can measure your heart rate and find the proper level of exercise intensity using the elec-
tronic monitor (see the ELECTRONIC MONITOR OPERATION GUIDE). First, set the monitor for 4
minutuu. FreEs the "STAR ,_'STOF" key and exercise ut a c;umfuriubiu pucu urdi; tile 4minutu=_
elapse. Immediately measure your heart rate using the PULSE function. If your heart rate is below
your Training Zone, increase your level of exertion. If your heart rate is too high, reduce your level
of exertion.
EXERCISE PATTERN
Each workout should consist of a basic 5-step pattern.
1. Arrest 2. Warm-up 3. Training Zone exercise 4. Cool-down 5. At rest
Warming up is an important part of your workout and should not be taken lightly. Warming up
prepares the body for more strenuous exercise by increasing the circulation, delivering more
oxygen to the muscles, and raising the body temperature. This can be done by stretching and
light calisthenics for 5-10 minutes prior to exercising.
Begin exercising at a light pace for a few minutes. Then increase the intensity to raise your heart
rate to your Training Zone for a period of 20-30 minutes.
Cooling down after vigorous exercise is important in aiding circulation and preventing soreness.
5-10 minutes of light exercise or stretching will allow the body to cool down.
12
EXERCISE FREQUENCY
To maintain or improve your condition you must work out 2-3 times per week following the pattern
described above. A day of rest between workouts is recommended. After several months of exer-
cise the number of workouts can be increased to 4-5 times per week. The key to a successful pro-
gram is REGUI_AR EXERCISE.

STRETCHING
The following stretches provide a good warm-up. Each
position should be held for 15 counts and performed for
three repetitions. Stretch slowly -- don't bounce.
HAMSTRING STRETCH
Sit with one leg extended. Bring the sole of the opposite
foot in, resting against the extended leg's inner thigh.
