Safety: Warnings and Cautions
Before using the Anti-Gravity Treadmill, please read this manual. As a physical therapist, trainer, or
clinician (the operator of the product), you must understand the safety features and user interface. We
want you and your clients or patients (the users of the product) to have a safe and enjoyable exercise
experience.
DANGER: Imminently hazardous situation to be avoided that will result in serious
injury or death.
•Do not modify the Anti-Gravity Treadmill electrical plug. The treadmill comes equipped with a
removable power cord with a NEMA 6-20 plug. You must have a NEMA 6-20 receptacle outlet to be
compatible. Substitution of this cable to accommodate international receptacles must ensure that the
cable is designed to carry 220V at 20A.
•Do not use any electrical adapters. To do so could result in an electrical shock hazard.
•Consult a qualified electrician before using any extension cords. Long extension cords may cause a
voltage drop to the Anti-Gravity Treadmill, which may cause it to operate improperly. AlterG provides
a 15ft (4.6m) power cord.
•Do not operate the Anti-Gravity Treadmill in wet or damp environments.
•When relevant, do not operate the heart rate monitor transmitter in conjunction with an electrical heart
pacemaker or similar device. The transmitter may cause electrical disturbances which can interfere
with pacemaker function.
•Always unplug the Anti-Gravity Treadmill before cleaning or servicing.
•Do not soak any part of the Anti-Gravity Treadmill with liquid during cleaning; use a sprayer or damp
cloth. Keep all liquids away from electric components. Always unplug the Anti-Gravity Treadmill
before cleaning and maintenance.
•Service should be performed by an authorized AlterG technician. Service by non-authorized AlterG
technicians will void the warranty. Contact AlterG before you or an electrician attempt any
maintenance.
•Do not place any liquids on any part of the Anti-Gravity Treadmill (except in the water bottle holders),
including the Anti-Gravity Treadmill running surface.
•Always keep the running surface clean and dry.
•Do not unplug or alter any of the internal wiring on the Anti-Gravity Treadmill after installation.
WARNING: Potentially hazardous situation to be avoided that could result in serious
injury or death.
•Users must consult with their physicians and obtain a medical exam before beginning any exercise
program. This is particularly true if users have any of the following: history of heart disease, high
blood pressure, diabetes, chronic respiratory disease, elevated cholesterol, if they smoke cigarettes,
are currently inactive, are obese, or have any other chronic disease or physical impairment.
•Users must stop exercising immediately and consult a physician if they feel faint, dizzy, experience
chest pains, nausea or any other abnormal symptoms while using the Anti-Gravity Treadmill.
CAUTION: Potentially hazardous situation to be avoided that may result in minor or
moderate injury.
•Always use the emergency safety lanyard supplied with the Anti-Gravity Treadmill. It should be
clipped to the user’s article of clothing while exercising. This is an important feature in case the user
falls during a workout session.

•Before operating the Anti-Gravity Treadmill, make sure the locking mechanism for the cockpit is
engaged and locked all the way into stanchions that frame the Anti-Gravity Treadmill. Failure to do so
may allow the cockpit to dislodge during operation, resulting in possible injury to the user.
•Read, understand and test the emergency stop procedure before use.
•Never leave children unsupervised around the Anti-Gravity Treadmill.
•Safety and effectiveness in pregnant women have not been established. Pregnant women or women
who may be pregnant should consult their physician before using the Anti-Gravity Treadmill.
•The Anti-Gravity Treadmill must be used under the supervision of a properly trained operator. At no
time should a user of the Anti-Gravity Treadmill exercise without appropriate supervision; even if
having been previously trained in the proper operation of the device.
•Set up and operate the Anti-Gravity Treadmill on a solid, level surface.
•Do not wear loose or dangling clothing while using the Anti-Gravity Treadmill. Do not store anything
(like shorts) inside the Anti-Gravity Treadmill bag.
•Prior to beginning a workout session, check to make sure there is no debris inside the Anti-Gravity
Treadmill.
•Keep hands away from the bag and frame structure during inflation to avoid pinching.
•Keep hands away from all moving parts.
•Do not use the Fit Anti-Gravity Treadmill if the user’s weight is less than 80lbs (39kg) or greater than
400lbs. (180kg). Users who weigh more than 350lbs (159kg) may not be able to unweight to the full
20% of original body weight.
•Care should be taken when the user enters and exits the Anti-Gravity Treadmill. Users should never
enter the Anti-Gravity Treadmill while the treadmill surface is moving. Ensure that the emergency stop
safety magnet is attached to the treadmill so that the treadmill belt is locked and will not move when
the user steps on the surface. Make sure the user holds onto the cockpit or handrails whenever
practical to support their body.
•Make sure that the user is fully zipped into the bag before beginning the workout session and that the
cockpit is adjusted at the correct height and locked in place.
•Make sure the user wears proper athletic shoes, such as those with rubber or high-traction soles. Do
not allow shoes with heels or leather soles. Make sure no stones or sharp objects are embedded in
the soles of the shoes.
•As with any treadmill workout, make sure the user includes a cool-down phase at the end of the
user’s workout session. Make sure they return to full body weight and exercise moderately before
stopping. Avoid abruptly ending or pausing the workout session while the user is at reduced body
weight or at high speed.
•The safety and integrity of the Anti-Gravity Treadmill can only be maintained when the Anti-Gravity
Treadmill is regularly examined for damage and wear and is properly repaired. It is the sole
responsibility of the user/owner or facility operator to ensure that regular maintenance is performed.
Worn or damaged components must be replaced immediately, and the Anti-Gravity Treadmill
removed from service until the repair is made. Only manufacturer supplied, or approved components
should be used to maintain and repair the Anti-Gravity Treadmill.
CAUTION: AlterG uses Neodymium magnets to hold the bag in place near the user.
Neodymium magnets are a member of the Rare Earth magnet family and are the most
powerful permanent magnets in the world. The Fit 100 product uses up to four N42
Neodymium magnets on each side of the bag. Each of these magnets can have as
much as 22 lbs. (10kg) of pulling force and a magnetic field of 13,200 Gauss.
Fortunately, the magnetic field drops very quickly from the magnet such that, at a
distance of 3 inches (7.6cm), the magnetic field is less than 100 Gauss in total.
Caution is advised if a user has a heart pacemaker, insulin pump, or other
electromagnetic products in use during a session within the AlterG Anti-Gravity
Treadmill. Always check with your healthcare professional prior to use of this
product.

Introduction
Consulting a Physician
Anyone considering an exercise program or an increase in activity should consult a physician. It is highly
recommended that users follow the guidance of their physician before and during an exercise program or
any other increase in physical activity if they:
•Have heart disease, high blood pressure, diabetes, chronic respiratory disease, or elevated
cholesterol
•Smoke cigarettes
•Are currently inactive, are obese, or have any other chronic disease or physical impairment, or if there
is a history of such disease in their family
Neodymium magnets can affect pacemakers.
The strong magnetic fields near a neodymium magnet can affect pacemakers, ICDs and
other implanted medical devices. Many of these devices are made with a feature that
deactivates it with a magnetic field. Therefore, care must be taken to avoid inadvertently
deactivating such devices.
The Importance of Warming Up and Cooling Down
It is important that users gradually warm up, cool down, and incorporate a series of stretches prior to and
at the end of each work out. Stretching encourages the necessary flexibility to help prevent sore muscles
and injury during daily activities.
Do not abruptly end the workout session on the Fit Anti-Gravity Treadmill. The user’s full body weight
should be restored slowly and should include a few minutes of walking at full body weight and low
intensity before stopping the workout session.

Setup and Installation
The Fit Anti-Gravity Treadmill will be installed by an AlterG qualified technician after delivery. Please
make sure that you inspect the Anti-Gravity Treadmill upon delivery for any damage that may have
occurred during transportation. Take photographs and report any damage immediately to the shipping
company and AlterG. When you sign for the shipment of your Anti-Gravity Treadmill, you are taking
responsibility for any damage that may occur before installation.
Electrical Requirements
The recommended electrical power connection for the Fit Anti-Gravity Treadmill is a dedicated
20 ampere, 220VAC @ 50/60 Hz circuit with ground. The plug supplied with the Anti-Gravity Treadmill is
designated by the NEMA configuration system as 6-20P. The corresponding receptacle for the plug is a
NEMA 6-20R.
An appropriate plug for the country and facility in question should be wired as follows:
Blue Conductor: Neutral
Brown Conductor: Line
Green/Yellow Conductor: Ground
Grounding Requirements
WARNING: To avoid the risk of electric shock, this equipment must only be connected to
a supply mains with protective earth.
The Fit Anti-Gravity Treadmill must be grounded electrically. If there is an electrical malfunction,
grounding provides a path of least resistance for electric current to reduce the risk of electric shock. The
Anti-Gravity Treadmill power cord includes a grounded plug. This plug must be plugged into an
appropriate receptacle (NEMA 6-20R) that is properly installed and grounded in accordance with the
current National Electrical Code as well as all local codes and ordinances. If you are at all unsure of these
requirements, contact AlterG or a qualified electrician.
Location Requirements
The Fit Anti-Gravity Treadmill measures 84” (213cm) ×38” (97cm) and weighs almost 550lbs (249kg). It
needs to be placed on a structurally sound surface. If it is used above ground level, it is advisable to place
it near the corner of the room or where the floor will be strongest to ensure maximum support during high-
speed, high-impact use. The surface should be level to ensure minimal flexing of the Anti-Gravity
Treadmill frame. Do not place the Anti-Gravity Treadmill directly on thick carpeting because it may
interfere with air-valves located on the underside of the treadmill. The Anti-Gravity Treadmill needs to be
within 12ft (3.7m) (from the front of the treadmill) of the proper electrical outlet. Check with a qualified
electrician or AlterG if you plan on extending the cord in any way. Make sure you leave at least 24”
(61cm) on either side of the treadmill to allow the bag to expand during inflation. Allow at least 40” (1m)
behind the treadmill to accommodate a user getting in and out safely, and at least 20” (.5m) in front of the
unit to allow access to electronics and power on/off switch.
We recommend an area at least 12ft (3.7m) long by 8ft (2.4m) wide to provide adequate space for
operation and user access. Also, check ceiling height to ensure that users will not hit their heads on the
ceiling while running. The Anti-Gravity Treadmill surface is 6” (15cm) off the floor. An 8ft (2.4m) ceiling
may be too low for taller users.
AlterG FIT Anti-Gravity Treadmill®Installations Specifications
•Maximum height of treadmill: 74” (1.88M)
•Width of treadmill: 38” (0.97M)
•Length of treadmill: 84” (2.13M)

Operation
Note: The following operating instructions are performed by, or at the direction of, a clinician.
Powering On the Anti-Gravity Treadmill
1. The power switch is located at the front of the
Fit Anti-Gravity Treadmill. Switch it on to start the
system and to boot up the software. As the software
loads, avoid touching the screen because it may
interfere with the boot-up process.
Note: Do not allow the user to stand on the Anti-
Gravity Treadmill belt during boot-up. If the user
inadvertently puts weight on the belt during boot-up,
an error message is displayed. Have the user stand
outside the unit until the boot sequence is complete.
2. The system is ready when the Welcome screen
appears.
Note: If you have not read this manual, it is
recommended that you QUIT now or seek
appropriate instruction from a qualified operator. By
tapping START SESSION, you acknowledge that
you have read and understand this manual.
Securing the User in the Anti-Gravity Treadmill
The procedures in this section describe:
•Putting on the shorts
•Stepping into the Anti-Gravity Treadmill
•Zipping into the bag
•Setting the cockpit height
•Attaching the safety lanyard
Putting on the Shorts
Your Anti-Gravity Treadmill comes with customized neoprene compression
shorts that ensure an airtight seal between the user’s body and the bag opening
of the treadmill. It is recommended that the user put the shorts on before
stepping into the treadmill.
Have the user select a size that is snug but not uncomfortable and make certain
the tag is at the user’s back and on the inside of the shorts. For a comfortable fit
and to prevent bunching, it is recommended that the user wear a pair of running
shorts or tights under the shorts.
Note: The shorts are latex-free (90% Neoprene, 10% Urethane coated Nylon).

D000505-00 Rev. E
15
Stepping into the Anti-Gravity Treadmill
CAUTION: Before the user steps into the Anti-Gravity Treadmill running surface, ensure
that the safety magnet is in place on the console. If the safety magnet is not in place, the
treadmill assumes there is a safety problem and disengages the running surface.
Before entering the treadmill ensure that the cockpit is at
the lowest level. Entering with the treadmill with the cockpit
in a higher position may cause the cockpit to move, with the
potential for the user to lose balance.
Enter the treadmill from the back and step into the bag
opening.
It is fine to step on the bag, but make sure that no rocks or
sharp objects are embedded in the soles of shoes that
could mar or damage the bag.
Note: The bag fabric does not contain latex.
Setting the Cockpit Height
1. Face forward and pull the lockbar toward you to
disengage the cockpit.

D000505-00 Rev. E
16
A “Cockpit Lock” message appears on the screen to
indicate that the cockpit is unlocked.
2. Grasp the handrails and slide the cockpit up or down to
set it at a height that places the zipper at the iliac crest
(the top, outer edge of the pelvic bone felt just below
waist level). For additional trunk support, the cockpit can
be set higher.
Note: Make sure there is sufficient room above the
handrails to allow your arms to swing comfortably during
the workout session.
Note: Inseam heights are posted on the side stanchions.
These can be used to mark the cockpit height for
different users.
For more information, see the description of the inseam
height labels in “Labels, Locations, Interpretation”.
3. With the cockpit at the correct height, make sure it
“clicks” into place, and then push the lockbar forward
(away from you) until it is fully engaged.

D000505-00 Rev. E
17
The “Cockpit Lock” message disappears, and the
Welcome screen appears.
4. Grasp the handle on each side of the bag and lift the bag
straight up to the handrails.
5. Pull up until both sides of the bag snap to the magnets
on the underside of the handrails.

D000505-00 Rev. E
18
CAUTION: Never operate the Anti-Gravity
Treadmill without the cockpit engaged in a locked
position. This is an essential safety item that prevents
the cockpit from inadvertently disengaging during an
exercise session.
Never attempt to move the cockpit while the bag is
inflating or when it is fully inflated. If the bag needs to be
repositioned while the user is exercising, stop the
session. You can then change the height of the cockpit.
Zipping into the Bag
When the cockpit is in place, zip into the Anti-Gravity
Treadmill. The zipper is started at the front and center of the
body and zipped counter-clockwise all the way around until it
returns to overlap in the front. Make sure that the zipper is
completely closed to complete the seal.
The zipper provides a means of quickly attaching and
detaching the user from the bag, simplifies hygiene, and
provides a custom fit for users of all sizes.

D000505-00 Rev. E
19
Attaching the Safety Lanyard
Always use the magnetic safety lanyard supplied with the Anti-Gravity Treadmill. If you lose the safety
magnet, order a replacement from AlterG. As a precaution, the treadmill will not operate without the
safety magnet directly over the Emergency Stop label.
Operator or User Action Screen
1. Slip the wrist strap of the lanyard around one wrist.
2. Place the lanyard safety magnet directly over the circular
indicator on the console labeled “Emergency Stop”;
otherwise, the Anti-Gravity Treadmill will not operate.
CAUTION: Never attempt to defeat this critical
safety feature by fastening the lanyard to the bag,
structure of the Anti-Gravity Treadmill, or anywhere else
other than to the user’s wrist.
Should the user fall while exercising, the magnet is
pulled off the console and power to the treadmill is cut;
air pressure is released; the treadmill running surface
disengages from its drive and can move freely. The
ESTOP message is displayed on the screen.
3. Continue to “Starting and Completing a Workout
Session”.

D000505-00 Rev. E

Starting and Completing a Workout Session
The procedures in this section describe:
•Starting a workout session
•Using the touchscreen features and controls
•Adjusting Anti-Gravity Treadmill speed
Starting a Workout Session
Operator or User Action Screen
1. Tap START SESSION on the Welcome screen.
2. Follow the instructions in the Before You Begin
screen, and then tap START CALIBRATION.
The calibration routine provides critical information
the Anti-Gravity Treadmill needs for accurate
control of body weight during exercise.
Note: For an accurate calibration, it is critical that
the user’s full body weight be applied to the belt
surface. Holding onto any other part of the
treadmill, for example, resting an arm on the top of
the bag while the treadmill calibrates, will result in
an erroneous calibration and inaccurate body
weight adjustment during exercise. It is
recommended that the user hold their arms out to
their sides or crossed on their chest, away from any
structures, during the calibration procedure.
When calibration is complete, the percentage of the
user’s body weight that can be unweighted is
displayed.
3. Tap START SESSION. The workout session
begins.
4. Use the features and controls on the touchscreen
to view and modify the workout session. See
“Using the Touchscreen Controls”.
