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 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
manufacturer have no ability to control. This part is
available through most electrical supply stores.
5
www.spirittness.com
This product is for use on a nominal 110-volt/15
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 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.
Examples: Grainger part # 1D237, or available
online at www.squared.com part #QO120HM.
The electrical outlet used should have a dedicated
15 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.

Spirit Fitness
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 CT850ENT 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.
31
www.spirittness.com
PROGRAMMABLE FEATURES
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!

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.
34
Spirit Fitness
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.
35
www.spirittness.com
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).
36
Spirit Fitness
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

GERKIN
The Gerkin protocol, also known as the reman’s protocol, is a sub-max 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 (VO2max) as shown in the chart below.
41
www.spirittness.com
Before The Test:
• Make sure you are in good health; check with your physician before performing any exercise if you are over the
age of 35 or persons with pre-existing health conditions.
• Make sure you have warmed up and stretched before taking the test.
• Do not take in caffeine before the test.
• Hold the hand grips gently, do not tense up.
During the Test:
• The console must be receiving a steady heart rate for the test to begin. You may use the hand pulse sensors or
wear a heart rate chest strap transmitter.
• The test will start with a 3-minute warm-up at 3 MPH before the actual test begins.
• The data shown during the test is:
1. Time indicates total elapsed time
2. Incline in percent grade
3. Distance in miles or kilometers depending on preset parameter.
4. Speed in mph or kph depending on preset parameter.
5. Target heart rate and Actual heart rate are shown in the Message window.
After the Test:
• Cool down for about one to three minutes.
• Take note of your score because the console will automatically return to the start-up mode after a few minutes.

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).

Spirit Fitness
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.

button to begin the workout or Stop button to return to the previous screen.
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.

Spirit Fitness
BELT/DECK
Your treadmill uses a very high-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 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 below.
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.

Spirit Fitness
TREADBELT TRACKING ADJUSTMENT
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.

CALIBRATION PROCEDURE
1. Remove the safety button.
2. Press and hold down the Start and Fast + buttons and replace the safety button. Continue to hold the Start and
Fast button until the window displays “Factory settings”, then press the Enter button.
3. You will now be able to set the display to show Metric or English settings (Miles vs. Kilometers). To do this, press
the up or down button to show which you want, then press Enter.
4. Make sure the wheel size diameter is 2.98 then press Enter.
5. Adjust the minimum speed (if needed) to 0.5 and then press Enter.
6. Adjust the maximum speed (if needed) to 12.0 and then press Enter.
7. Adjust the maximum elevation (if needed) to 15 and then press Enter.
8. Grade return – On (This allows the incline to return to zero when Stop is pressed. For sale in Europe, EU standards
require this to be off).
9. Press Start to begin calibration. The process is automatic; the speed will start up without warning, so do not stand
on the belt.
ADJUSTING THE SPEED SENSOR
If the calibration does not pass you may need to check the speed sensor alignment.
1. Remove the motor cover hood by loosening the 8 screws that hold it in place. Set it aside.
2. The speed sensor is located on the left side of the frame, right next to the front roller pulley
(the pulley will have a belt around it that also goes to the motor). The speed sensor is a
small rectangular shaped black box with a wire connected to it.
3. You will see a magnet on the outside edge of the pulley; make sure the speed sensor is
aligned with the center of the magnet when it passes by. There are two a screws that hold
the sensor in place that need to be loosened to adjust the sensor. Re-tighten the screws
when nished.
