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 equipmentgrounding conductor can result in a risk of
electric shock. Check with a qualified
electrician or service provider if you are in
doubt as to whether the treadmill is properly
grounded. Seek a qualified electrician to
perform any modifications to the cord or
plug. Cybex is not responsible for injuries or
damages as a result of cord or plug
modification.
This treadmill is for use on a nominal 115 VAC
±5%, 60 Hz and 20 amps, 208/220 VAC; 60 Hz,
15 amps or 230 VAC ±5%, 50 Hz and 15 amps
and a grounded, dedicated circuit. Make sure
that the treadmill is connected to an outlet
having the same configuration as the plug. Do
not use a ground plug adapter to adapt the
power cord to a non-grounded outlet.

Data Readouts
As you exercise, the treadmill keeps track of the following data:
Cybex Sport Treadmill Owner’s & Service Manual
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.
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.
Heart Rate — Your current heart rate. Heart rate will appear when a signal is
introduced. Use the handgrips for Contact Heart Rate.
Pace — At your current speed, how long it would take to cover a mile (or
kilometer), displayed in minutes:seconds.
Metabolic Equivalent — Relates to the user's energy expenditure. 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 consumed at
rest. For example two METs would be twice that amount. 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.

Data displayed during a program: The top center display will continually review each set of
data. Each set of data is displayed for 3 seconds before the next set is displayed. The
corresponding LED lights as the data is displayed.
To review accumulated data after a program: The display automatically cycles through your
accumulated workout data during the Workout Review for up to 20 seconds.
Displaying Heart Rate
In order for the Cybex Sport to display your heart rate, 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
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. It is
recommended that the user have clean hands when using the contact heart rate.
Cybex Sport Treadmill Owner’s & Service Manual
Operation
Page 3-7
Heart Rate Zone
Heart Rate is described by the number of times your heart beats in a minute. At rest, the
average adult will have a heart rate of about 72 beats per minute (bpm). As one begins to
exercise, heart rate increases and continues to increase as exercise intensity or difficulty
increases.
Monitoring your heart rate is an effective way to control the intensity of your workout and
subsequently the results it will have. Whether you are a new participant or one with a great
deal of experience, weight loss and other performance goals can be achieved by controlling
the intensity of your workout.
The American College of Sports
Medicine recommends that healthy
adults exercise between 55 and 85%
of their heart rate max. Your heart rate
max can be estimated by subtracting
your age from 220. Multiply that
estimated heart rate max by .55 to
estimate the lower end of your heart
rate training zone. Then multiply your
estimated heart rate max by .85 to
estimate the higher end of your
training zone. This heart rate training
zone gives you a range of intensities at
which to exercise.
NOTE: A label is located on the
accessory tray to remind you
what the heart rate zone is
while you are working out.
See Figure 4.
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.
Cybex Sport Treadmill Owner’s & Service Manual
Figure 4
This label shows heart rate based on
percentage and age.
Operation
Page 3-8
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).

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 Sport, you may choose from three different programs. The program choices are
summarized as follows:
Quick Start You control speed, elevation. Maximum of 60 minutes.
Manual Mode You control speed, elevation. 30 minutes (fixed time).
Weight Loss 10 Levels 30 minutes (fixed time)
Cardio 10 Levels 20 minutes (fixed time)
Manual
Program Overview
Manual Mode is available both through Quick Start and through the Manual program where
you are prompted to make a user weight adjustment. NOTE: There is no diagram because
incline and speed are user-controlled.
Manual Mode allows you to choose settings as you workout. You may choose your settings
according to how you feel or your endurance level. Since you remain in control, Manual Mode
may be the best choice for beginners or for those who have not worked out in a long time.
NOTE: Manual Mode is not a preprogrammed workout.
Press the Quick Start key to workout in Manual Mode. You can also begin Manual Mode by
pressing the Manual program key. To increase or decrease the speed while in Manual Mode
use the Speed
+ — keys. To increase or decrease the incline while in Manual Mode use
the arrows.

loss
When you workout in Manual Mode, be sure to include a three-to-five minute warm-up and
cool-down period. You can warm-up by setting a slow speed for walking/jogging on the
treadmill at zero incline and then gradually increase the speed to the target for your workout.
Reverse this process for your cool-down period, slowing down the speed gradually and
returning the incline to zero.
Weight Loss
Program Overview
This program was designed to help individuals of all fitness levels achieve their weight loss
goals through a protocol that incorporates both low and moderate intensity activity. Because
walking has become a popular mode of exercise for those looking to lose weight, all levels of
this program are performed at walking speeds.
The core of the program is made up of five one-minute segments. The first segment
represents the baseline of the program and may also be considered to be a “rest” segment
later. In minutes two and three, elevation will be increased. In minute four, the program returns
to the first segment baseline or rest level. In the fifth minute, the speed will increase. The total
number of segments used is dictated by the time selected by the user.
Higher levels of the Weight Loss program incorporate jogging speeds in short segments. This
allows the advanced walker to alternate walking and jogging.
• At levels 1-6 walkers maintain walking speeds only.
• At levels 7-10, experienced walkers can jog intermittently.
By mixing the use of speed and elevation separately, the user receives the benefits of added
intensity intervals but the variety does not allow for either speed or elevation to dominate and
therefore overtax the user. See table below and Figure 5.

Cardio
Program Overview
This program was designed for the exercise participant who wants to improve the overall
efficiency of their cardio-respiratory system. Unlike some of the other treadmill programs that
incorporate low and moderate intensity segments, the Cardio program contains overall higher
intensity levels with more moderate recovery segments.
The speed range of the program includes walking speeds at the lower levels up through a
moderate jog in the higher levels.
Elevation is used to emphasize the high intensity portion of this program while decreased
elevation and a small increase in speed mark the recovery segment. High intensity and
recovery segments are always in a one-to-one time based ratio and make up the core eight
minutes of the program. See table below and Figure 6.

for your treadmill. Instruct all personnel in equipment inspection and maintenance
actions and also in accident reporting/recording. Contact Cybex Customer Service at
800-766-3211 or 508-533-4300 for any preventive maintenance or service concerns.
Cleaning Your Treadmill
When cleaning your treadmill spray a mild cleaning agent, such as a water and dishsoap
solution, on a clean cloth first and then wipe the treadmill with the damp cloth.
Cybex Sport Treadmill Owner’s & Service Manual
Preventive
Maintenance
Page 4-1
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 airflow can prevent adequate
cooling that could shorten motor life. Cleaning this area should be done as often as indicated
in the Service Schedule.
! 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 finished.
Lift the rear of the treadmill and roll it back from its present position so as to vacuum the floor
area underneath the unit. Wipe clean the underside of the treadmill to prevent dirt and dust
build-up. When finished, 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
Cybex Sport Treadmill Owner’s & Service Manual
Preventive
Maintenance
Page 4-2
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.
A. Use a 3/4" socket wrench to turn each bolt 1/2 turn clockwise. See Figure 1.
NOTE: Be sure to adjust each bolt equally on each side.
B. Turn the power on and press the Quick Start key.
C. Press the Speed
+ to bring the speed up to 3.5-4 mph (5.6-6.4 kph). Allow the
treadmill to run for a minute.
D. Observe the belt to be sure it stays centered. If it is not centered follow step 2.
E. Walk on the belt to see if it still slips. If it does restart this procedure at step 1 A. If you
have to do this procedure three times and it still slips check the drive belt tension in the
Service chapter or call Cybex Customer Service. Follow the next step to be sure the
belt is centered.
! CAUTION: 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.
Cybex Sport Treadmill Owner’s & Service Manual
Figure 1
Preventive
Maintenance
Page 4-3
A. With the treadmill running at 5 mph (8 kph) observe the running belt. If the belt tracks
off center to 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.
B. After the belt has been centered, check the belt tension again. Make sure the running belt
tension is tight enough so that the belt does not slip or hesitate when stepped on. Walk
on the treadmill at 3.5-4 mph (5.6-6.4 kph) and every 4th to 5th step throw your weight
into 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.
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.
A. Turn the main power switch on the left side to the off (O) position.
B. Unplug the treadmill from the
power outlet.
2. Remove the motor cover.
A. Using a Phillips head screwdriver,
loosen three screws on each motor
cover side (left and right). See Figure 2.
B. Lift the motor cover up and off the
treadmill. The screws will stay in
place. See Figure 2.
3. Remove the end caps.
A. Using a Phillips head screwdriver,
remove the screw that holds each
end cap in place. See Figure 3.

B. Grasp each top step and lift it out
and off the treadmill. See Figures
3 and 4.
6. Check the belt and deck condition.
A. Look at the edges of the belt while you roll it by hand. If the belt has any rips or looks
excessively worn the belt needs to be replaced.
B. Run your hand under the belt on the top of the deck surface. If you feel excessive
ridges or cracks, or if the deck feels grooved yet highly polished, the deck should be
replaced. In time, a worn belt and deck can cause high current draw and ultimately,
motor failure. For instructions on replacing the belt and deck, see Running Belt and
Deck in the Service chapter.
7. Clean under the belt.
A. To minimize the effect of friction between the deck and the running belt, Cybex
recommends 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.

screws are catching the center motor cover’s holes.
Other Preventive Maintenance
Other preventive maintenance activities must be completed by a qualified 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
NOTE: See the Service chapter of this manual for detailed procedures for the maintenance
activities listed above.
Elevation Motor Lubrication — In time the elevation motor pivot points may develop a
squeak. If a squeak is present, remove the elevation motor by following the Elevation Motor
procedure in the Service chapter. 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 humidifier.

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 & 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 39” (1.0 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 first floor, place it near or above major support beams. If the area has
a heavy, plush carpet, the airflow 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.

NOTE: Cybex recommends that the treadmill be unplugged or the on/off (I/O) power switch
turned off (O) when it is not in use.
4. Press the Quick Start key. The treadmill begins a countdown “3...2...1” and sounds a tone
for each count. After it reaches one (1), the treadmill gives a longer tone and then begins
accelerating the belt to reach 1 mph (1.6 kph).
5. The bottom left display will flash the time and the right display will show the actual speed.
6. Press and hold down the Speed
+
key until the treadmill reaches a speed of
approximately 4 mph (6.4 kph), as indicated on the display.
7. Observe the belt to see that it is running properly; it should stay centered
in the middle of the deck. If you have problems with the running belt operation, see
Running Belt Adjustments in the Preventive Maintenance chapter.
8. Run the treadmill through its full speed range. First press the Speed
+
key until the
treadmill reaches its highest speed, 10 mph (16 kph). Then press the Speed
- key until
the treadmill is back to 1.0 mph (1.6 kph).
9. As you press the Incline or Speed + - keys, the respective displays will show the
actual incline or speed.
10. When the treadmill reaches the set incline and speed, the displays will remain steadily
illuminated to indicate that the desired settings have
been reached.

2. Place your finger on the + key (but do not press the key at this time) and watch as the
center display changes.
3. When “unit” appears on the display you will have 3 seconds to toggle the unit of
measurement to your preference by pressing the
+ key. Choose English or Metric units;
English is the default. NOTE: Metric appears as “nnE”.
4. When “line” appears on the display you will have 3 seconds to toggle the line frequency.
Choose 50 Hz or 60 Hz. NOTE: If you have an English console and a 50 Hz power line
frequency, then you must change the setting from 60 Hz to 50 Hz for the proper elevation
frequency. Line Frequency is the frequency of the power line that supplies power to
your treadmill.
5. To exit Test Mode press the Stop key twice.
Your treadmill is now ready for use. Follow the instructions in the Operation chapter of this manual
