Important Electrical Instructions
WARNING!
Route the power cord away from any moving part of the treadmill including the elevation mechanism and
transport wheels.
NEVER remove any cover without first 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 specification is 40 to 120 degrees
Fahrenheit, and humidity is 95% non-condensing (no water drops forming on surfaces).
Circuit Breakers: Avoid AFCI/GFCI circuit breakers if possible. These breakers may trip occasionally during
exercise because of the high inrush currents of the treadmill drive electronics and motor. This is an issue that
affects all treadmill brands.
New laws in your area may require these breakers. If you do have these breakers and outlets in your home, and
are experiencing nuisance tripping, you should check if there are any other devices plugged into the same circuit.
Some examples of devices that may also cause tripping are fluorescent lights with electronic ballasts, coffee
maker, space heater, hair drier. Optimally the treadmill should be the only device plugged into the circuit.
Our treadmills have surge suppressors built in to help avoid nuisance tripping. We have tested several AFCI/GFCI
breakers and outlets with our products. Brands we have tested are: Eaton (Cutler Hammer Series), Leviton (Smart
lock pro) and Schneider Electric (Canadian home series). These breakers do not trip in our testing, when
connected to our treadmills, as long as no other devices are plugged into the same circuit.
Grounding Instructions
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 productis
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 qualified 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 fit the outlet; have a
proper outlet installed by a qualified 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 qualified 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.

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 householdpower
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 functionproperly
with little finger pressure.
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.
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.
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 theequipment.
SAVE THESE INSTRUCTIONS - THINK SAFETY!
Pre-Assembly
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 flat 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 treadmillup
to gain access to the strap end.

confusion and mix ups.
Pull the carton over the treadmill parts and lay it on a level surface.

Finishing Assembly
Note: Once your treadmill is fully assembled, be sure to check the belt lubrication
before initial use by completing the following steps:
1. Ensure that your machine is off, and that the power cord is unplugged to minimize
risk of injury.
2. Use one hand to hold the treadmill belt up just enough so you can use your other
hand reach between the belt and deck to verify that lubrication is present.
If lubrication is present, you may continual normal use. If lubrication is not present,
please follow the steps on page 29 to lubricate your treadmill belt using approved
treadmill belt lubricant.
