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 used in
homes 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
house 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
home 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
6
Spirit Fitness
available through most electrical supply stores. Examples: Grainger part # 1D237, or available online at
www.squared.com part #QO120HM. The electrical outlet used should have a dedicated 20 amp circuit
breaker.
GROUNDING INSTRUCTIONS
This product must be grounded. If the treadmill should malfunction or breakdown, 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 120-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 below may
be used to connect this plug to a 2-pole receptacle as shown below if a properly grounded outlet is not
available. The temporary adapter should be used only until a properly grounded outlet, (shown below)
can be installed by a qualied electrician. The green colored rigid ear-lug, or the like, extending from the
7
www.spirittness.com
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.
• Understand that changes in resistance do not occur immediately. Set your desired resistance level on the computer
console and release the adjustment button. The computer will obey the command gradually.
• Use caution while participating in other activities while pedaling 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 buttons. They are precision set to function properly with little
nger pressure.
WARNING
This product can expose you to chemicals including Toluene and Acrylamide which are known to the State of California
to cause Cancer and birth defects or other reproductive harm. For more information, go to www.P65Warnings.ca.gov

POWER
Power the treadmill on by plugging it into an appropriate wall outlet, then turn on the power switch located
at the front of the treadmill below the motor hood. Ensure that the safety button is installed, as the treadmill
will not power on without it.
When the power is turned on, all the lights on the display will light for a short time. Then the Time and
Distance windows will display odometer readings for a short time. The Time window will show how many
hours the treadmill has been in use and the Distance window will show how many miles (or Kilometers if
the treadmill is set to metric readings; see maintenance for changing settings) the treadmill has gone. A
message will be displayed showing the current software version. The treadmill will then enter idle mode,
which is the starting point for operation.
CSAFE FEATURE
Your console is equipped with a CSAFE feature. The Power (POWER) port can
be used for powering a remote controlled audio-visual system by connecting
a cable from the remote to the Power port at the back of the console. The
Communication port (COMM) can be used to interact with tness software
applications.
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 tread-belt. Pulling this safety tether
cord will stop tread-belt 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.
17

QUICK START
• Press and release any button to wake display up if not already on.
• Press and release the Start button to begin belt movement at 0.5mph, then adjust to the desired speed using the
Up/Down Speed buttons. You may also use the Direct Access Speed Buttons 1 through 15 to set to a specic
speed directly.
• To slow the treadmill belt press and hold the Speed Down button (console or hand rail) to the desired speed. You
may also press the Direct Access Speed Buttons, 1 through 15.
• To stop the treadmill belt press and release the red Stop button.
PAUSE/STOP/PRESET
• When the treadmill is running the pause feature may be utilized by pressing the red Stop button once. This will
slowly decelerate the treadmill belt to a stop. The incline will go to zero percent. The Time, Distance and Calorie
readings will hold while the unit is in the pause mode. After 5 minutes the display will reset and return to the start
up screen.
• To resume your exercise when in Pause mode, press the Start button. The speed and incline will return to their
previous settings.
• Pressing the Stop button twice will end the program and a workout summary will be displayed. If the Stop button
is pressed a third time, the console will return to the idle mode (start up) screen.
• If the Stop button is held down for more than 3 seconds the console will reset.
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 switch in
normal operation.
18
Spirit Fitness
• When you are setting data, such as age and time, for a program pressing the Stop button will allow you to go
back one step for each button press.
INCLINE
• Incline may be adjusted anytime after the belt starts moving.
• Press and hold the adjust Incline Up/Down buttons to achieve desired level of effort. You may also choose a
more rapid increase / decrease by selecting a rapid incline button, 1 through 15, on left hand side of console

made.
DOT MATRIX MESSAGE CENTER
Ten rows of dots indicate each level of a workout in manual mode. Displays messages that help guide you
through the programming process. During a program the message window displays your workout data.
The dots are only to show an approximate level (speed/incline) of effort. They do not necessarily indicate
a specic value - only an approximate percent to compare levels of intensity. In Manual Operation the
Speed / Incline Dot Matrix Message Center will build a prole “picture” as values are changed during a
workout. There are twenty-four columns, indicating time. The 24 columns are divided into 1/24th of the
total time of the program. When the time is counting up from zero (as in quick start) each column represents
1 minute.
Next to the Dot Matrix Message Center are three LED lights labeled: Track, Speed and Incline, along with
a Up/Down Scan button. When the Track LED is lit the Dot Matrix Message Center displays the Track
prole, when the Speed LED is lit the Dot Matrix Message Center displays the Speed prole and when the
Incline LED is lit it displays the Incline prole. You may change the prole view by pressing the Up/Down
19
www.spirittness.com
Scan button. After scrolling through the three proles the Dot Matrix Message Center will automatically
scroll through the three displays showing each one for four seconds. The LED associated with each prole
will blink while that view is displayed. One more press of the Up/Down Scan button will return you to the
Track prole.
1/4 MILE TRACK
The 1/4-mile track (0.4 km) will be displayed around the dot matrix window. The ashing dot indicates
your progress. In the center of the track there is a lap counter for reference.
HEART RATE WINDOW
The Pulse (Heart Rate) window will display your current heart rate in beats per minute during the workout.
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 CT850 will also pick up wireless heart rate transmitters that are Polar compatible,
including coded transmissions.

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.

HILL
This program follows a triangle or pyramid type of gradual
progression from approximately 10% of maximum effort (the level
that you chose before starting this program) up to a maximum
effort which lasts for 10% of the total workout time, then a gradual
regression of resistance back to approximately 10% of maximum
effort
FAT BURN
This program follows a quick progression up to the maximum
resistance 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.
CARDIO
This program presents a quick progression up to near maximum
resistance level (default or user input level). It has slight uctuations
up and down to allow your 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
23
www.spirittness.com
INTERVAL
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. Your cardiovascular system gets
programmed to use oxygen more efciently.
HIIT

GERKIN TEST
The Gerkin protocol, also known as the reman’s protocol, and is a submax Vo2 (volume of oxygen) test.
The test will increase speed and elevation alternately until you reach 85% of your Max heart rate. The time
it takes for you to reach 85% determines the test score (Vo2 max) as shown in the chart below.

HEART RATE PROGRAMS
The old motto, “no pain, no gain”, is a myth that has been overpowered by the benets of exercising
comfortably. A great deal of this success has been promoted by the use of heart rate monitors. With the proper
use of a heart rate monitor, many people nd that their usual choice of exercise intensity was either too high or
too low and exercise is much more enjoyable by maintaining their heart rate in the desired benet range.
To determine the benet range in which you wish to train, you must rst determine your Maximum Heart Rate.
This can be accomplished by using the following formula: 220 minus your age. This will give you the Maximum
Heart Rate (MHR)for someone of your age. To determine the effective heart rate range for specic goals you
simply calculate a percentage of your MHR. Your Heart rate training zone is 50% to 90% of your maximum
heart rate. 65% of your MHR is the recommended for burning fat while 85% is recommended for strengthening
the cardio vascular system. This 65% to 85% is the zone to stay in for maximum benet.
For someone who is 40 years old their
target heart rate zone is calculated:
220 – 40 = 180 (maximum heart rate)
180 x .65 = 117 beats per minute (65% of maximum)
180 X .85 = 153 beats per minute (85% of maximum)
So for a 40 year old the training zone would
be 117 to 153 beats per minute.
33
www.spirittness.com
If you enter your age during programming the console will perform this calculation automatically. Entering
your age is used for the Heart Rate programs. After calculating your MHR you can decide upon which
goal you would like to pursue.
The two most popular reasons for, or goals, of exercise are cardiovascular tness (training for the heart and
lungs) and weight control. The black columns on the chart represent the MHR for a person whose age is
listed at the bottom of each column. The training heart rate, for either cardiovascular tness or weight loss,
is represented by two different lines that cut diagonally through the chart. A denition of the lines’ goal
is in the bottom left-hand corner of the chart. If your goal is cardiovascular tness or if it is weight loss, it
can be achieved by training at 85% or 65%, respectively, of your MHR on a schedule approved by your
physician. Consult your physician before participating in any exercise program.
With all Spirit Fitness treadmills you may use the heart rate monitor feature without using the Heart Rate
program. However, when using the heart rate monitor feature in conjunction with the Heart Rate programs,
the machine will automatically adjust speed or incline to maintain the desired heart rate.
HEART RATE CONTROL
Heart Rate Control (HRC) uses your treadmill’s incline system to control your heart rate. 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 setup 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
34
Spirit Fitness
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. You must receive a strong / steady value in heart rate window or the program will not start. Dot Matrix Message
Center will show “Check Pulse” if there is no pulse signal.
2. Use the Program button to select the HR program to begin.
3. The Dot Matrix Message Center 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 default program.
4. When Enter is pressed, the Dot Matrix Message Center will read, “Press 1 or 2 to select then press Enter”. At the
same time, the Dot Matrix Message Center will show “1”.
5. The Dot Matrix Message Center will show “Adjust Time then press Enter” with the Time window blinking. Use the
Up/Down & Fast/Slow buttons to adjust. After setting a time, press Enter.
6. The Dot Matrix Message Center will prompt you to enter Age. Press Enter once adjusted.
7. The Dot Matrix Message Center will prompt you to enter Body Weight. Press Enter once adjusted.
8. The Dot Matrix Message Center will prompt you to enter Heart Rate. Press Enter once adjusted.
9. Press Start to begin your workout or Enter to modify. Press Stop to return to the previous screen.

RATE OF PERCEIVED EXERTION
There are more variables involved in how hard you should workout than just heart rate. Your stress level,
physical health, emotional health, temperature, humidity, the time of day, the last time you ate and what
you ate, all contribute to the intensity at which you should workout.
The rate of perceived exertion (RPE), also know as the Borg scale, was developed by Swedish physiologist
G.A.V. Borg. The scale helps users determine an approximate heart rate level when a heart rate monitor
was not in use. Using the scale below, rate the level of intensity of your workout, or the perception of your
effort during your workout. Once the rating has been determined, simply add a “0” to the rating to get
your approximate heart rate. For example, if your workout felt comfortable, you would rate it a “12”. Then
add a “0” to get an approximate heart rate during your workout of 120 beats per minute. The scale is as
follows:
Rating Perception of Effort
6 Minimal
7 Very,very light
8 Very,very light +
9 Very light
10 Very light +
11 Fairly light

WEARING THE CHEST STRAP (SOLD SEPARATELY)
1. Attach the transmitter to the elastic strap using the interlocking button.
2. Adjust the strap as tightly as possible while ensuring it is still comfortable.
3. Position the transmitter with the logo centered in the middle of your torso facing away
from your chest (some people must position the transmitter slightly left of center). Attach
the nal end of the elastic strap by inserting the round end and, using the locking
parts, secure the transmitter and strap around your chest.
4. Position the transmitter directly below the pectoral muscles.
5. Sweat is the best conductor to measure very minute heart beat electrical signals.
However, plain water can also be used to pre-wet the electrodes (2 ribbed oval
areas on the reverse side of the belt and both sides of the transmitter). It’s also recommended that you wear
the transmitter strap a few minutes before your work out. Some users, because of body chemistry, have a more
difcult time in achieving a strong, steady signal at the beginning. After “warming up”, this problem lessens.
6. Your workout must be within range - distance between transmitter/receiver – to achieve a strong steady signal.
The length of range may vary somewhat but generally stay close enough to the console to maintain good, strong,
reliable readings. Wearing the transmitter directly on bare skin assures you of proper operation. If you wish, you
may wear the transmitter over a shirt. To do so, wet the areas of the shirt that the electrodes will rest upon.
Note: The transmitter is automatically activated when it detects activity from the user’s heart. Additionally, it
automatically deactivates when it does not receive any activity. Although the transmitter is water resistant,
moisture can have the effect of creating false signals, so you should take precautions to completely dry the
transmitter after use to prolong battery life (estimated transmitter battery life is 2500 hours). The replacement
battery is CR2032. The chest strap is sold separately. Chest straps that operate using Bluetooth or ANT+
should also work with this machine.

ERRATIC OPERATION
Caution! Do not use this treadmill for Heart Rate programs unless a steady, solid Actual Heart Rate
value is being displayed. High, wild, random numbers being displayed indicate a problem.
Areas to look for interference which may cause erratic heart rate:
1. Microwave ovens, TV’s, small appliances, etc.
2. Fluorescent lights.
3. Some household security systems.
4. Electric fence for a pet.
5. Some people have problems with the transmitter picking up a signal from their skin. If you have problems try
wearing the transmitter upside down. Normally the transmitter will be oriented so the Spirit Fitness logo is right
side up.
6. The antenna that picks up your heart rate is very sensitive. If there is an outside noise source, turning the whole
machine 90 degrees may de-tune the interference.
7. Another Individual wearing a transmitter within 3’ of your machine’s console.
If you continue to experience problems contact your dealer.

BELT ADJUSTMENTS
Tread-belt Tension Adjustment - Belt tension is not critical for
most users. It is very important though 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 to the right.
Tighten the rear roller only enough to prevent slippage at the front roller. Turn the tread-belt 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.
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 that belt is loose it feels similar to the walking belt being loose.
Tightening the motor belt should be done by a trained service person.
BELT/DECK
Your treadmill uses a very high-efcient and proprietary belt/deck combination. 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 deck is designed to withstand up to 4,000 hrs on each side. If the original side
of the deck use is over 4000 hrs, then it needs to be ipped. Contact your service technician for assistance. Do
not apply any type of lubricant or wax to the surface.

The treadmill is designed so that the tread-belt 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 TREAD-BELT TRACKING
An 8mm Allen wrench is provided for this adjustment. Make
tracking adjustments on the left side bolt. Set belt speed at 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 tread-belt. Adjustments will become less of a
maintenance concern as the belt is used. Proper belt tracking is an owner responsibility common with
all treadmills.
ATTENTION: Damage to the running belt resulting from improper tracking / tension adjustments is not
covered under the Spirit Fitness warranty.

Display does not light
Tread-belt 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 Tread-belt Tension. Adjust as necessary.
1. If the belt moves, but stops after a short time and
thedisplay shows “LS”, run calibration.
2. If you press start and the belt never moves, then the
display shows LS, contact service.
Motor is not responsive after pressing start
Need to replace the breaker with a “High In-rush current”
type breaker (see page 3 for details)
Circuit breaker trips, but not the treadmill circuit
breaker
PROBLEM SOLUTION/CAUSE
43
www.spirittness.com
Treadmill will only achieve approximately 7 mph but
shows higher speed on display
This indicates motor should be receiving power to oper-
ate. Low AC voltage to treadmill. 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 volt-
age. Contact an electrician or your Spirit Fitness dealer.
A minimum of 120 volt AC current is required.
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.
Tread-belt stops quickly/suddenly when tether cord
is pulled
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
if it is on its original side.
Treadmill trips on board 20 amp circuit
Treadmill may not be grounded. Static electricity is
“crashing” the computer. Refer to Grounding Instructions
on page 6.
Tighten all bolts. Check that machine is leveled. Adjust
levelers if needed using a wrench.
Computer shuts off when console is touched (on
a cold day) while walking/running
Noises while in uses (squeaks, bumps, clicking, etc.)
