always unplug this treadmill from the electrical
outlet immediately after using and before cleaning.
WARNING
To reduce the risk of burns, re electric shock, or
injury to persons:
• Before beginning this or any exercise program,
consult a physician. This is especially important for
persons over the age of 35 or persons with pre-
existing health conditions.
• Keep children away from the treadmill. There are
obvious pinch points and other caution areas that can
cause harm.
• Keep hands away from all moving parts.
• Never drop or insert any object into any openings.
• Do not use outdoors.
• Do not attempt to use your treadmill for any purpose
other than for the purpose it is intended.
• The hand pulse sensors are not medical devices.
Various factors, including the user’s movement, may
affect the accuracy of heart rate readings. The pulse
sensors are intended only as exercise aids in determining
heart rate trends in general.
• Wear proper shoes. High heels, dress shoes, sandals,
or bare feet are not suitable for use on your elliptical.
Quality athletic shoes are recommended to avoid leg
fatigue.
• Maximum User Weight: 450 lbs,
• This appliance is not intended for use by persons with

Spirit Fitness
• ASTM F2115-05 Specications 6.1.2.11—The
recommended minimum clearance required around
each treadmill for access to, passage around, and

SAVE THESE INSTRUCTIONS - THINK SAFETY!
IMPORTANT ELECTRICAL
INSTRUCTIONS
WARNING
NEVER use a ground fault circuit interrupt (GFCI)
wall outlet with this treadmill. As with any appliance
with a large motor, the GFCI will trip often. Route
the power cord away from any moving part of the
treadmill including the elevation mechanism and
transport wheels.
NEVER remove any cover without rst disconnecting
AC power. If voltage varies by ten percent (10%)
or more, the performance of your treadmill may be
affected. Such conditions are not covered under your
warranty. If you suspect the voltage is low, contact
your local power company or a licensed electrician
for proper testing.
NEVER expose this treadmill to rain or moisture.
This product is NOT designed for use outdoors,
near a pool or spa or in any other high humidity
environment. The operating temperature specication
is 40 to 120 degrees Fahrenheit, and humidity is
95% non-condensing (no water drops forming on
surfaces).
Circuit Breakers: Some circuit breakers are not
rated for high inrush currents that can occur when a
treadmill is rst turned on or even during use. If your
treadmill is tripping the circuit breaker (even though
it is the proper current rating) but the circuit breaker
on the treadmill itself does not trip, you will need to
replace the facility breaker with a high inrush type.
This is not a warranty defect. This is a condition we
as a manufacture have no ability to control. This part
is available through most electrical supply stores. The
electrical outlet used should have a dedicated 20
amp circuit breaker.

www.spirittness.com
GROUNDING INSTRUCTIONS
This product must be grounded. If the treadmill should
malfunction or break down, grounding provides a
path of least resistance for electric current, reducing
the risk of electric shock. This product is equipped
with a cord having an equipment-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 qualied electrician or
serviceman if you are in doubt as to whether the
product is properly grounded. Do not modify the
plug provided with the product if it will not t the
outlet; have a proper outlet installed by a qualied
electrician.
This product is for use on a nominal 110 volt/20
amp dedicated circuit, and has a grounding plug
that looks like the plug illustrated below. A temporary
adapter that looks like the adapter illustrated may be
used to connect this plug to a 2-pole receptacle as
shown if a properly grounded outlet is not available.
The temporary adapter should be used only until
a properly grounded outlet can be installed by a
qualied electrician. The green colored rigid ear-
lug, or the like, extending from the adapter, must be
connected to a permanent ground such as a properly
grounded outlet box cover. Whenever the adapter is
used, it must be held in place by a metal screw.
IMPORTANT OPERATION
INSTRUCTIONS
• NEVER operate this treadmill without reading
and completely understanding the results of any
operational change you request from the computer
console.
• Understand that changes in speed or incline do
not occur immediately. Set your desired speed or
incline level on the computer console and release
the adjustment key. The computer will obey the
command gradually.
• Use caution while participating in other activities
while on your Treadmill; such as watching television,
reading, etc. These distractions may cause you to
lose balance which may result in serious injury.
• Do not use excessive pressure on console control
keys. They are precision-set to function properly with
little nger pressure.

HEART RATE FEATURE
The Pulse (Heart Rate) on the screen shows the current value of the heart beats per minute. You must use
both left and right stainless steel sensors to pick up your pulse. Pulse values are displayed anytime the
computer is receiving a Grip pulse signal. You may use the Grip pulse feature while in Heart Rate Control.
The CT900ENT will also pick up wireless heart rate transmitters that are Polar compatible.
TO TURN TREADMILL OFF:
The screen will automatically turn off (go to sleep) after 30 minutes of inactivity. This function is called sleep
mode. In sleep mode, the treadmill will power down most everything except for a minimum of circuitry
for detecting button presses and the safety key so it will start up again if these are activated. There is only
a tiny amount of current used in sleep mode (about the same as your TV when it is turned off) and it is
perfectly ne to leave the main power switch on in sleep mode. Of course you may also remove the safety
key or turn off the main power switch to power down the treadmill.
30
Spirit Fitness
PROGRAMMING THE CONSOLE
Each of the programs can be customized with your personal information and changed to suit your needs.
Some of the information asked for is necessary to ensure the readouts are correct. You will be asked for
your Age and Weight. Entering your Age ensures that the Heart Rate bar graph shows the correct number.
Your Age is also necessary during the Heart Rate control program to ensure the correct settings are in the
program for your Age. Otherwise the work settings could be too high or low for you; entering your Weight
aides in calculating a more correct Calorie reading. Although we cannot provide an exact calorie count
we do want to be as close as possible.
CALORIE NOTE: Calorie readings on every piece of exercise equipment, whether it is in a gym or at
home, are not accurate and tend to vary widely. They are meant only as a guide to monitor your progress
from workout to workout. The only way to measure your calorie burn accurately is in a clinical setting
connected to a host of machines. This is because every person is different and burns calories at a different
rate. Some good news is that you will continue to burn calories at an accelerated rate for at least an hour
after you have nished exercising!

P1= HILL; P2= FAT BURN; P3= CARDIO; P4= INTERVAL
PRESET PROGRAMS SPEED/INCLINE SETTINGS
The preset program Speed and Incline levels are shown in the chart below. The Speed numbers shown in
the chart indicate a percentage of the top speed of the program. For instance, the rst Speed setting for P1
(Program 1, HILL) shows the number 20.This means that this segment of the program will have a speed that
is 20% of the top speed for the program (The user sets the top speed in the procedure above). If the user
sets the top speed to 10 mph, then the rst segment will be 2 mph. You will notice that segment 12 shows
100 which means the speed will be set to 100% of 10 mph or simply 10 mph.
33
www.spirittness.com
MANUAL
Both Speed and Incline are controlled by the user. Increase
or decrease levels at any time during your workout.
HILL
Speed: This program follows a triangle or pyramid type of gradual
progression from approximately 10% of maximum effort (the level
that you choose before starting this program) up to a maximum
effort which lasts for 10% of the total workout time, then a gradual
regression of Speed back to approximately 10% of maximum effort
Incline: The deck elevation is a more gradual and sustained
progression. Maximum elevation is in the middle of the workout
and lasts for 10% of the duration.
FAT BURN
Speed: This program follows a quick progression up to the
maximum speed level (default or user input level) that is sustained
for 2/3 of the workout. This program will challenge your ability to
sustain your energy output for an extended period of time.
Incline: The deck elevation is a quick and sustained progression up
to the maximum value (default or user input) for 90% of the workout
duration.
34
Spirit Fitness
CARDIO
Speed: This program presents a quick progression up to near maximum
speed level (default or user input level). It has slight uctuations up and
down to allow heart rate to elevate, and then recover repeatedly,
before beginning a quick cool down. This will build up your heart
muscle and increase blood ow and lung capacity.
Incline: The elevation in this program is moderate. There are several
elevation spikes at different points of the workout. Segments 4, 9,
and 14 are maximum elevation for this program.
STRENGTH
Speed: This program has a gradual progression of speed up to
100% of maximum effort that is sustained from 25% of workout
duration. This will help build strength and muscular endurance in
the lower body and gluten. A brief cool down follows.
Incline: There is a quick climb to a moderate, sustained elevation
that lats the majority of the workout length.
5K RUN
Both speed and incline are controlled by the user. Increase or
decrease levels at any time during your workout. The track display
will set the distance of 1 lap to 5 kilometers (metric) or 3.1 miles
(standard measurement).
35
www.spirittness.com
INTERVAL
Speed: This program takes you through high levels of intensity
followed by recovery periods of low intensity. This program utilizes
and develops your “Fast Twitch” muscle bers which are used
when performing tasks that are intense and short in duration. These
deplete your oxygen level and spike your heart rate, followed by
periods of recovery and heart rate drop to replenish oxygen.
Incline: All of your lower extremity muscles will be equally
challenged throughout this program. The incline alternates
between 25% and 65% of maximum elevation.
HR
The default value is 65% of your projected rate maximum. You
have the option of changing your target heart rate. The machine
will attempt to keep you within ve beats of your target heart rate.
CUSTOM
You will create the desired speed and incline levels for each of the
20 segments of the program using the pop out keyboard on the
screen. After the program has started, you still have the ability of
changing these levels whenever you desire.

CALORIE PROGRAM
Speed: This program follows a progression up to the maximum speed level (default or user inout level) that is
sustained for 2/3 of the workout. This program will challenge your ability to sustain your energy output for an
extended period of time.
Incline: The treadmill elevation is a quick and sustained progression yup to the maximum value (default or user
input) for 90% of the workout duration.
10K RUN
Both speed and Incline are controlled by the user. Increase or decrease levels at any time during your workout. The
track Display will set the distance of 1 Lap to 10 kilometers (metric) or 6.2 miles (standard measurement).

HEART RATE PROGRAM
Heart Rate Control (HRC) uses your treadmill’s incline system to control your heart rate via information from pulse grips or
wireless chest strap. Increases and decreases in elevation affect heart rate much more efciently than changes in speed
alone. The HRC program automatically changes elevation gradually to achieve the programmed target heart rate.
Selecting a Heart Rate Control Program:
You have the option, during the set up mode, to choose either the Weight control (HR 1) program or the Cardiovascular
(HR 2) program. The Weight control program will attempt to maintain your heart rate at 60% of your Maximum Heart
Rate. The Cardiovascular program will attempt to maintain your heart rate at 85% of your Maximum Heart Rate.
Your Maximum Heart Rate is based upon a formula that subtracts your age from a constant of 220.Your HR setting is
automatically calculated during the setup mode when you enter your age.
Heart Rate Control programming:
1. Press HR button to enter heart rate program.
2. Now the window will show PRESS ENTER TO MODIFY OR START TO BEGIN WORKOUT. You can either press
the Enter button for settings or press the Start button to execute the program.
3. When the Enter button is pressed, the Message window shows PRESS 1 OR 2 TO SELECT THEN PRESS ENTER.
At the same time, the dot matrix window is showing “1” and you can press numeric keypad 1 or 2 and then the
Enter button.
4. Now Message Window is showing ADJUST TIME THEN PRESS ENTER with Time Window blinking. Use
Up/Down buttons or numeric keys to adjust. After setting time, press the Enter button again.
5. Now Message window is showing ADJUST AGE THEN PRESS ENTER with Incline Window blinking. Use
Up/Down/ Fast/Slow buttons or numeric keys to adjust. Adjusting age will change HR value (as the HR formula
described previously). After age is set, press the Enter button again.

Note: When the Message Window is showing CHECK PULSE, there is no pulse signal received and the program cannot
be performed. Please check and make sure that heart rate strap functions normally.
SAFETY TETHER CORD
A safety tether cord is provided with this unit. It is a simple magnetic design that should be used at all times. It
is for your safety should you fall or move too far back on the treadbelt. Pulling this safety tether cord will stop
treadbelt movement. To Use:
1. Place the magnet into position on the round metal portion of the console control head. Your treadmill will not start
and operate without this. Removing the magnet also secures the treadmill from unauthorized use.
2. Fasten the plastic clip onto your clothing securely to assure good holding power. NOTE: The magnet has strong
enough power to minimize accidental, unexpected stopping. The clip should be attached securely to make certain
it does not come off. Be familiar with its function and limitations. The treadmill will stop, depending on speed,
with a one to two step coast anytime the magnet is pulled off the console. Use the Stop/Pause button in
normal operation.

BELT/DECK
Your treadmill uses a very highly efcient, low-friction, hard waxed deck. Performance is maximized
when the deck is kept as clean as possible. Use a soft, damp cloth, or paper towel, wipe the edge of
the belt and the area between the belt edge and the frame. Also reach as far as practical directly under
the belt edge. This should be done once a month to extend belt and deck life. A mild soap and water
solution along with a nylon scrub brush will clean the top of the textured belt. Allow to dry before using.
The low maintenance (routine monthly cleaning) dual-sided, hard-wax deck is designed to withstand up
to 20,000 miles on each side. If the original side of the deck shows signicant wear, it needs to be
ipped. Contact your service technician for assistance. Do not apply any type of lubricant or wax to the
surface.
BELT ADJUSTMENTS
Belt tension important for joggers and runners in order to provide
a smooth, steady running surface. Adjustment must be made from
the rear roller with the 8mm Allen wrench provided in the parts
package. The adjustment bolts are located at the end of the step
rails as shown in the diagram below.
Tighten the rear roller only enough to prevent slippage at the front roller. Turn the treadbelt tension adjusting
bolts 1/4 turn each and inspect for proper tension by walking on the belt and making sure it is not
slipping or hesitating with each step. When an adjustment is made to the belt tension, you must be sure
to turn the bolts on both sides evenly or the belt could start tracking to one side instead of running in the
middle of the deck.
46
Spirit Fitness
DO NOT OVER TIGHTEN – Over tightening will cause belt damage and premature bearing failure. If you
tighten the belt a lot and it still slips, the problem could actually be the drive belt (located under the motor
cover) that connects the motor to the front roller. If drive belt is loose it feels similar to the walking belt being
loose. Tightening the motor belt should be done by a trained service person.

TREADBELT TRACKING ADJUSTMENT
The treadmill is designed so that the treadbelt remains reasonably centered while in use. It is normal for some
belts to drift near one side while in use, depending on a user’s gait and if they favor one leg. But if during use
the belt continues to move toward one side, adjustments are necessary.
SETTING TREADBELT TRACKING
An 8mm Allen wrench is provided for this adjustment. Make
tracking adjustments on the left side bolt. Set the belt speed to
3 mph. Be aware that a small adjustment can make a dramatic
difference which may not be apparent right away. If the belt is
too close to the left side, then turn the bolt only a 1/4 turn to the
right (clockwise) and wait a few minutes for the belt to adjust itself.
Continue to make 1/4 turns until the belt stabilizes in the center of
the running deck.
If the belt is too close to the right side, turn the bolt counter-clockwise. The belt may require periodic tracking
adjustment depending on use and walking/running characteristics. Some users may affect tracking differently.
Expect to make adjustments as required to center the treadbelt. Adjustments will become less of a maintenance
concern as the belt is used. Proper belt tracking is an owner responsibility common with all treadmills.

TROUBLESHOOTING
PROBLEM CAUSE
Display does not light 1. Tether cord not in position.
2. Circuit breaker on front grill tripped. Push circuit breaker in until it locks.
3. Plug is disconnected. Make sure plug is rmly pushed into115 VAC wall outlet.
4. Breaker panel circuit breaker may be tripped.
Treadbelt does not stay centered Treadmill belt
hesitates when walked/run on
The user may be walking while favoring or putting more weight on either the left or right foot. If this walking pattern
is natural, track the belt slightly off-center to the side opposite from the belt movement. See General Maintenance
section on Treadbelt Tension. Adjust as necessary.
Motor is not responsive after pressing start Reset power. If still unresponsive, contact service.
Circuit breaker trips, but not the treadmill circuit
breaker
Need to replace the breaker with a “High in-rush current” type breaker (see page 4 for details)
Treadmill will only achieve approximately 7 mph
but shows higher speed on display
This indicates motor should be receiving power to operate. Do not use an extension cord. If an extension cord is
required, it should be as short as possible and heavy duty, 16-gauge minimum, low voltage. Contact an electrician
or your Spirit Fitness dealer. A minimum of 110-volt AC current is required.
Treadbelt stops quickly/suddenly when tether
cord is pulled
High belt/deck friction. See General Maintenance section on cleaning the deck. If cleaning doesn’t prevent this
from reoccurring, check to see if there is signicant wear of the deck. If so, the deck may need to be ipped if it is
on its original side.
Treadmill trips on board 20 amp circuit High belt/deck friction. See General Maintenance. If cleaning doesn’t prevent this from reoccurring, check the amp
draw of the motor. If this is high and there are signs of signicant wear of the deck, it may need to be ipped on its
original side.
Computer shuts off when console is touched
(on a cold day) while walking/running
Treadmill may not be grounded. Static electricity is crashing the computer. Refer to Grounding Instructions.
