Grounding Instructions

This treadmill must be grounded. If it should malfunction or break down, grounding provides a path of
least resistance for electric current to reduce the risk of electric shock. This product is equipped with a
cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into
an appropriate outlet that is properly installed and grounded in accordance with all local codes and
ordinances.

DANGER: Improper connection of the equipment-grounding conductor can result in a risk of

electric shock. Check with a qualifi ed electrician or service provider if there is doubt as
to whether the treadmill is properly grounded. Seek a qualifi ed electrician to perform
any modifi cations to the cord or plug. Cybex is not responsible for injuries or damages
as a result of cord or plug modifi cation.

This treadmill is for use on a
grounded, dedicated circuit. Make
sure that the treadmill is connected
to an outlet having the same
confi guration as the plug. Do not
use a ground plug adapter to adapt
the power cord to a non-grounded
outlet.

Warnings/Cautions

All warnings and cautions listed in this chapter are as follows:

WARNING: Use extreme caution when assembling the treadmill. Failure to do so could

result in injury.

CAUTION: A minimum of two people are required to lift, move and assemble this treadmill. Always

use proper lifting methods when moving heavy items.

CAUTION: Do not pinch your hands or other body parts while pivoting the treadmill.

See Figure 3.

CAUTION: During this procedure STAY OFF THE RUNNING BELT! Stand with your feet

on the two steps.

Choosing and Preparing a Site

Before assembling the treadmill you must select a suitable site and have the proper electrical outlet
power available for optimum operation and safety. See the Electrical Power Requirements section
(located on the next page) for direction in locating your treadmill's voltage requirements.

The area you select for the treadmill should be well lit and well ventilated. Locate the treadmill on a
structurally sound and level surface (do not place in recessed areas or on plush carpet) a few feet away
from walls and other equipment. Each side of the treadmill should have a 19.7” (0.5 m) minimum space.
Behind the treadmill should be 79” (2.0 m) minimum of space. Allow enough clearance for safe access
and passage during use of the machine. If the treadmill is to be located above the fi rst fl oor, place it near
or above major support beams. If the area has a heavy, plush carpet, the airfl ow around the base of the
machine may be restricted or the carpeting may interfere with the moving parts. To protect the carpeting
and the machinery, place a 3/4” (1.9 cm) thick wood base under the treadmill.

Do not install the treadmill in an area of high humidity, such as in the vicinity of a steam room, sauna,
indoor pool, or outdoors. Exposure to extensive water vapor, chlorine, and/or bromine could adversely
affect the electronics as well as other parts of the machine.

Cybex Pro3 Treadmill Owner’s Manual

Data Readouts

As you exercise, the treadmill keeps track of the following data:

DIST (Distance) – The total accumulated distance, in miles or kilometers, during your
workout. NOTE: Depending on the defaults you’ve chosen this measurement will show

in English or Metric.

CAL (Calories) – The total accumulated calories burned during your workout. Your
weight must be correctly set before beginning your workout for this measurement to be
most accurate.

METS (Metabolic Equivalent) – Relates to the user's energy expenditure. ‘One met’
is the amount of oxygen consumed at rest. For example two mets would be twice that
amount. See METs in this chapter for a more detailed description.

MIN MI/KM (Pace) – At your current speed, how long it would take to cover a mile (or
kilometer), displayed in minutes:seconds.

Heart Rate – Your current heart rate. Heart rate will appear when a signal is
introduced. Use either the handgrips for Contact Heart Rate or a Polar compatible
heart rate transmitter. See Heart Rate LED for a description of colors.

To review accumulated data after a program: The display automatically cycles through your
accumulated workout data during the Workout Review for 20 seconds (default setting).

Displaying Heart Rate

In order for the Cybex Pro3 to display your heart rate, you must either use a Polar compatible heart rate
transmitter belt (not included) or hold the handgrips to use Contact Heart Rate.

Contact Heart Rate – Hold the handgrips on the console crossbar until a heart rate is displayed,
typically less than thirty seconds. For best results, hold the handgrips lightly and ensure that your hands
contact both the front and back sensors of each grip. NOTE: Hold your hands as steady as possible as

movement can cause interference on the contacts.

Factors that can interfere with the heart rate signal include:

excessive movement•
body composition•
hydration•
too loose grip•
too tight grip•
running•
excessive dirt, powder or oil •
leaning or resting on grips•

Operation

Page 3-7

Cybex Pro3 Treadmill Owner’s Manual

NOTE: Cybex does not recommend continuous holding onto the contact heart rate grips during exercise.

Contaminants, such as hand lotions, oils or body powder, may come off on the contact heart rate grips.
These can reduce sensitivity and interfere with the heart rate signal. Therefore, ensure you have clean
hands when using the contact heart rate.

NOTE: When wearing a Polar compatible transmitter, the contact heart rate will dominate only when

the grips are held.

Polar Compatible Reception – To use this feature, a Polar compatible heart rate transmitter belt must
be worn. To view heart rate continuously, press the Scan key when the Heart LED is lit or press the
Heart key.

Heart Rate LED

When the handgrips are held the center display switches to show the heart rate in beats per minute (BPM)
if you are not scanning. For several seconds the display will show “---”. Once the actual heart rate is
determined the center window displays the BPM and the Heart LED lights up. See Figure 4. The color
of the light represents a scale of low to high target heart rate.

Blue = 0-69 beats per minute
(RESTING)
Green = 70-93 beats per minute
(WARM-UP)
Yellow = 94-120 beats per minute
(FAT BURN ZONE)
Red = 121-170 beats per minute
(CARDIO ZONE)
Purple = 171 and up beats per minute

NOTE: A label is on the console to remind

you what the color represents while
you are working out. See Figure 4.

The color of the heart LED

Use of Programs

WARNING: Obtain a medical exam before beginning any exercise program. Begin comfortably

with a lower level and progress with higher levels as you become acclimated.

With the Cybex Pro3, you may choose from fi ve different programs. Each program provides ten levels
of diffi culty for a choice of fi fty different preprogrammed options. You may also use Manual Mode. With
this unique combination of programs, you can tailor your workout to achieve exactly the fi tness goals you
desire, including: weight loss, conditioning, endurance or maintenance of overall health. The program
choices are summarized as follows:

Manual You control speed, elevation, and time.
5K Run 10 Levels (5 kilometers) Time varies according to speed
9 Holes 10 Levels (1 mile) Time varies according to speed
HR Control Level is your Minutes vary according to time selected

Target Heart Rate

Cardio 10 Levels Minutes vary according to time selected
Weight Loss 10 Levels Minutes vary according to time selected

Operation

Page 3-9

Cybex Pro3 Treadmill Owner’s Manual

The Workout Profile

The Workout Profi le matrix in the center of the display uses columns of lights to show the progress of
your workout. The height of the column represents METS, specifi cally the highest METS you reached in
that period. Each column represents 1 minute of your total workout time when in Manual Mode and 15
seconds in every other program.

NOTE: It is conceivable to have two segments of different speed and elevation combinations in the same

met range.

METs

A MET is a basic unit of measurement that is used to compare relative work between individuals and
activities. One MET is the amount of oxygen an individual consumes at rest. If an individual were working
at four METs he/she would be consuming oxygen at a rate equal to four times their resting consumption.
METs can be used to compare walking on a grade with running or even to cycling and other activities.

Meaning of % Grade

A 1% grade is not the same as a 1 degree incline.The % grade is the relationship of the measurement of
rise over the measurement of run (also called slope). For example, a 1 foot (meter) rise in height over a
length of 100 feet (meters) is a 1% grade. Expressed as a mathematical formula, the grade is calculated
as follows: 1 ft. (m) / 100 ft. (m) = 0.01 = 1%

With respect to treadmills, the percent grade is roughly equal to the increase in height (rise) of the
treadmill divided by the length (run) of the treadmill.

The degree of incline can be related to % grade by taking the Tangent of the grade. For instance, 15%
grade is equal to 8.53 Degrees (Tan(.15)=8.53º). The opposite is true to determine % Grade from Degree
of incline (ArcTan (8.53º)=.15).

Cleaning Your Treadmill

When cleaning your treadmill spray a mild cleaning agent, such as a water and dishsoap solution, on a
clean cloth fi rst and then wipe the treadmill with the damp cloth.

NOTE: Do not spray cleaning solution directly on the treadmill. Direct spraying could cause damage to

the electronics and may void the warranty.

WARNING: To prevent electrical shock, be sure that power is shut off and the treadmill is

unplugged from the electrical outlet before performing any cleaning or maintenance
procedures.

After Each Use – Wipe up any liquid spills immediately. After each workout, use a cloth to wipe up any
remaining perspiration from the handrails and painted surfaces.

Be careful not to spill or get excessive moisture between the edge of the display panel and the console,
as this might create an electrical hazard or cause failure of the electronics.

As Needed – Vacuum any dust or dirt that might accumulate under or around the treadmill. Motors are
especially susceptible to dust and dirt, and restricted airfl ow can prevent adequate cooling that could
shorten motor life. Cleaning this area should be done as often as indicated in the Service Schedule, more
often in dusty environments.

WARNING: Keep wet items away from inside parts of the treadmill. Electrical shock could occur

even if the treadmill is unplugged. Do not touch components on the lower board.
A charge can remain after unplugging the power cord and turning off the treadmill.

To clean the motor components, you must loosen the six Phillips head screws that hold the motor cover in
place. Lift the cover straight up; the screws and side covers will stay in place. Use a vacuum attachment
or hand vacuum to clean the exposed elevation assembly, drive motor, lower electronics and the
surrounding areas.

Also use a dry cloth for the areas that you can't reach with the vacuum cleaner. If the machine has not
been used for some time or is excessively dirty, use a dry cloth to wipe all exposed areas. Replace the
cover and tighten the screws when fi nished.

Lift the rear of the treadmill and roll it back from its present position so as to vacuum the fl oor area
underneath the unit. Wipe clean the underside of the treadmill to prevent dirt and dust build-up. When
fi nished, return the treadmill to its normal position.

Contact Heart Rate Grips – Contaminants, such as hand lotions, oils or body powder, may come off
on the contact heart rate grips. These can reduce sensitivity and interfere with the heart rate signal. It is
recommended that the user have clean hands when using the contact heart rate. Clean the grips using
a cloth dampened with a cleaning solution containing alcohol. The grips are the only part of the treadmill
you should use a cleaning solution containing alcohol.

Running Belt Maintenance

Belt and Deck – Clean the belt and the deck surfaces to minimize the effect of friction between the wood
deck and the running belt. Clean the underside of the running belt and the top of the running deck surface
by wiping them with a clean dry towel. This should be done often to prevent premature wear of the deck,
running belt, and the drive motor system. See the Service Schedule in this chapter to determine the
minimum recommended cleaning.

The running belt may become loose and slip on the drive roller with each foot plant. If it does, follow the
Tensioning and Centering the Belt in this chapter. See the Service Schedule in this chapter for a minimum
schedule for checking the belt tension.

Tension and Center the Belt – If the belt is slipping under each step perform this procedure:

Tools Required

3/4” Socket wrench •

1. Tension the belt.

Use a 3/4” socket wrench to turn each bolt 1/2 turn clockwise. See Figure 1. A.

NOTE: Be sure to adjust each bolt equally on each side.

Turn the power on and press the B. Quick Start key.

Figure 1

Press the C. Speed + - keys to bring the speed up to 3.5-4 mph (5.6-6.4 kph). Allow the treadmill to
run for a minute.

Observe the belt to be sure it stays centered. If it is not centered follow step 2.D.
Walk on the treadmill at 3.5-4 mph (5.6-6.4 kph) and every 4th to 5th step throw your weight into E.

your step to feel if the belt is slipping. If the belt does slip, use a wrench to equally tighten both
rear roller adjustment bolts 1/2 of a turn (clockwise). Adjust the belt until no further slipping is felt. If
the running belt continues to slip the drive belt could be loose. Follow the next step to be sure the
belt is centered.

NOTE: Be careful not to over tighten the belt. Over tightening the belt can cause the belt to

stretch and require replacement.

2. Center the belt.

NOTE: While centering the belt choose one bolt to adjust. Do not adjust both bolts.

With the treadmill running at 5 mph (8 kph) observe the running belt. If the belt tracks off center to A.
the right or left the deck will become exposed. Use a 3/4” socket wrench to tighten the rear roller
bolt on the side of the treadmill toward which the belt is moving. For example: If the belt moves to
the right and the deck becomes exposed on the left, tighten the bolt on the right side of the frame,
tighten about 1/2 of a turn (clockwise) and wait 30 seconds. If the belt does not move back to the
center of the treadmill, make another adjustment to the same bolt. Once the running belt has
been adjusted closer to the center of the treadmill use about 1/4 of a turn until the belt has been
stabilized.

After the belt has been centered, check the belt tension again. Make sure the running belt tension B.
is tight enough so that the belt does not slip or hesitate when stepped on. Refer to step 1E.

Checking the Belt and Deck Surfaces – The running belt and deck should be checked periodically for
any excessive wear. In an effort to make sure that the running belt operates properly, visually inspect the
belt often to make sure that there are no tears or fraying in the belt material.

Inspect the edges of the belt as described below. NOTE: It is necessary to remove the motor cover and

plastic side panels.

Tools Required

Phillips head screwdriver•
Dry towel•

1. Disconnect the external power source.

Turn the main power switch on the left side to the off (O) position.A.
Unplug the treadmill from the power outlet.B.

2. Remove the motor cover.

6. Check the belt and deck condition.

Look at the edges of the belt while A.
you roll it by hand. If the belt has any
rips or looks excessively worn the belt
needs to be replaced.

Run your hand under the belt on the top of the deck surface. If you feel excessive ridges or B.
cracks, or if the deck feels grooved yet highly polished, the deck should be fl ipped to an unused
surface or replaced. In time, a worn belt and deck can cause high current draw and ultimately,
motor failure. NOTE: When replacing the deck, replace the belt at the same time.

7. Clean under the belt.

To minimize the effect of friction between the deck and the running belt, Cybex recommends A.
cleaning the underside of the running belt and the top of the running deck surface by wiping
them with a clean, dry towel. This cleaning should be done each time you check the belt and
deck condition to prevent premature wear of the deck, running belt and the drive motor system.
See the Service Schedule in this chapter.

Other Preventive Maintenance

Other preventive maintenance activities must be completed by a qualifi ed service technician at the
recommended intervals listed in the Service Schedule (shown on the next page). These activities include:

Measure the motor brushes and replace worn motor brushes•
Rotate and replace the running deck•
Replace the running belt•
Check the current draw•
Measure motor voltage at maximum speed, with no load•

Elevation Motor Lubrication — In time the elevation motor pivot points may develop a squeak.
Lubricate the upper and lower bolts and the spacers with a small amount of lithium grease. NOTE: You

can buy lithium grease at an auto parts store.

Static Electricity – Depending upon where you live, you may experience dry air, causing a common
experience of static electricity. This may be especially true in the winter time. You may notice a static
build-up just by walking across a carpet and then touching a metal object. The same can hold true while
working out on your treadmill. You may experience a shock due to the build-up of static electricity on your
body and the discharge path of the treadmill. If you experience this type of situation, you may want to
increase the humidity to a comfortable level through the use of a humidifi er. A worn running belt looses
it’s ability to dissipate static electricity and should be replaced as needed.
