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 specication 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 available through most
electrical supply stores. Examples: Grainger part # 1D237, or available online at www.squared.com part
#QO120HM.
This product must be grounded. If the treadmill should malfunction or breakdown, grounding pro-
vides 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 appropri-
ate 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 qualied 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 qualied electrician.
This product is for use on a nominal 110-volt 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 con-
nect 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 qualied 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.

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.
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.
NEVER operate this treadmill without reading and completely understanding the results of any
operational change you request from the computer.
Understand that changes in speed and incline do not occur immediately. Set your desired work
level on the computer console and release the adjustment key. The computer will obey the
command gradually.
NEVER use your treadmill during an electrical storm. Surges may occur in your household power
supply that could damage treadmill components. Unplug the treadmill during an
electrical storm as a precaution.
Use caution while participating in other activities while walking 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.

SAFETY TETHER CORD
Failure to follow all guidelines may compromise the effectiveness of the exercise experience, expose
yourself (and possibly others) to injury, and reduce the longevity of the equipment.
Please read before unpacking your folding treadmill. Serious injury could occur if this folding treadmill
is not unpacked properly.
There is a Velcro strap installed around the treadmill base that prevents the treadmill from unfolding
accidentally during shipping. If this strap is not removed properly the treadmill could spring open unex-
pectedly and cause injury if someone is standing near the treadmill when the strap is removed.
To ensure your personal safety during removal of the shipping strap please make sure the treadmill
is positioned at on the ground, in the orientation it would be in if you were using the treadmill. Do not
turn the treadmill up on its side while removing the shipping strap. This could cause the treadmill’s
folding mechanism to spring open. If the end of the Velcro strap (that you need to grab to remove it)
happens to be under the treadmill deck, reach under the deck to grab it, but do not tilt the treadmill up
to gain access to the strap end.

The old motto, “no pain, no gain”, is a myth that has been overpowered by the benets 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 benet range.
To determine the benet range in which you wish to train, you must rst determine your predicted
Maximum Heart Rate. This can be accomplished by using the following formula: 220 minus your
age. This will give you the predicted Maximum Heart Rate (MHR) for someone of your age. To de-
termine the effective heart rate range for specic goals you simply calculate a percentage of your
MHR. Your heart rate training zone is 50% to 90% of your maximum heart rate. 60% of your MHR
is the zone that burns fat, while 80% is for strengthening the cardio vascular system. This 60% to
80% is the zone to stay in for maximum benet.
For someone who is 40 years old their
predicted target heart rate zone is calculated:
220 – 40 = 180 (maximum heart rate)
180 x .6 = 108 beats per minute
(60% of maximum)
180 X .8 = 144 beats per minute
(80% of maximum)
So for a 40 year old the training zone would be
108 to 144 beats per minute.
The two most popular reasons for, or goals, of ex-
ercise are cardiovascular tness (training for the
heart and lungs) and weight control. The black
columns on the chart above 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 denition 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 80% or 60%,
respectively, of your MHR on a schedule approved by your physician. Consult your physician
before participating in any exercise program.
Heart Rate

16
TRX3500 Treadmill
Heart rate is important but listening to your body also has a lot of advantages. 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. If you listen to your body it will tell you all of these things.
The rate of perceived exertion (RPE), also known as the Borg scale, was developed by
Swedish physiologist G.A.V. Borg. This scale rates exercise intensity from 6 to 20
depending upon how you feel or the perception of your effort.
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
12 Comfortable
13 Somewhat hard
14 Somewhat hard +
15 Hard
16 Hard +
17 Very hard
18 Very hard +
19 Very,very hard
20 Maximal
You can get an approximate heart rate level for each rating by simply adding a zero to
each rating. For example a rating of 12 will result in an approximate heart rate of 120
beats per minute. Your RPE will vary depending on the factors discussed earlier. If your
body is strong and rested, you will feel strong and your pace will feel comfortable. When
your body is in this condition, you are able to train harder and the RPE will support this. If
you are feeling tired and sluggish, it is because your body needs a break. In this
condition, your pace will feel difcult. Again, this will show up in your RPE and you
will train at the proper level for that day.

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 6mm 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 XTERRA Fitness warranty.
Treadbelt Tracking Adjustment
General Cleaning
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 6mm 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.
Dirt, dust, and hair can block air inlets and accumulate on the running belt. Please vacuum
underneath your treadmill on a monthly basis to prevent excess build-up of dirt that can get sucked
up and get into the inner workings under the motor cover. Every other month, you should remove the
motor cover and carefully vacuum out dirt and hair that may accumulate.
UNPLUG THE POWER CORD BEFORE THIS TASK.

TRX3500 Treadmill
First, you want to clean between the belt and deck to remove any debris that may be trapped. Use a
clean, non-fraying rag, t-shirt, or light towel. Halfway between the end of the treadmill and motor cover,
shove the garment under the belt until you can grasp it on both sides of the belt. Drag the garment the
length of the entire belt 1-2 times. Remove the garment.
Do not lubricate with anything other than XTERRA Fitness approved lubricant. Your treadmill comes

Keeping the deck lubricated at the recommended intervals ensures the longest life possible for
your treadmill. If the lubricant dries out, the friction between the belt and deck rises and places
undue stress on the drive motor, drive belt and electronic motor control board, which could result in
catastrophic failure of these expensive components. Failure to lubricate the deck at
regular intervals may void the warranty.
The belt & deck come pre-lubricated and subsequent lubrication should be performed every 180
hours of use or if you notice that the deck is dry. It is recommended that you reach between the
belt and deck to verify there is lubrication present, every other month. If you check and there isn’t
any lubrication present, follow the procedure below even though the “Lube” indicator isn’t lit on the
console. Otherwise, lubricate when the console’s lubrication reminder lights after 180 hours of use.
Use the following procedure to apply the silicone lubricant:
1. Turn the power switch off and unplug the power cord from the wall outlet
2. Measure 18” from the edge of the motor cover; kneel down and reach under the belt approxi-
mately 4- 6” from one edge. Squirt a line of lubricant about 1/8” wide x 15” long in an “S” pattern
perpendicular to the motor cover.
3. Repeat the process on the opposite side.
4. Plug the electrical cord back into the outlet and turn the power switch on.
5. Walk on the belt at a moderate speed for ve minutes to evenly distribute the silicone lube.
Note: If the “Lube” message appears on the console, perform the following procedure to
reset the message:
1. In standby mode, hold the ENTER key for 3 seconds to reset the message.
Belt/Deck Lubrication Procedure
DO NOT OVERTIGHTEN – 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.
