SAVE THESE INSTRUCTIONS
Read all instructions before using this treadmill. When using an electrical product, basic precautions
should always be followed, including the following: Read all instructions before using this treadmill. It is the
responsibility of the owner to ensure that all users of this treadmill are adequately informed of all warnings
and precautions. If you have any questions after reading this manual, contact Customer Tech Support at the
number listed on the back panel of this manual.
Connect this exercise product to a properly grounded outlet only. See grounding
instructions.
GROUNDING INSTRUCTIONS
This product must be grounded. If a treadmill should malfunction or breakdown, grounding provides a path
of least resistance for electrical current to reduce the risk of electrical shock. This product is equipped with
a cord having an equipment-grounding conductor and a grounding plug. The plug must be plugged into an
appropriate outlet that is properly installed and grounded in accordance with local codes and ordinances.
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 120-volt circuit, and has a grounding plug that looks like the plug
illustrated below. A temporary adapter such as the one illustrated below may be used to connect this plug to
a 2-pole receptacle as shown, if a properly grounded outlet is not available. The temporary adapter should
be used only until a properly grounded outlet 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.

ASSEMBLY
IMPORTANT: READ THESE SAFETY INSTRUCTIONS BEFORE USE!
During the assembly process of the treadmill there are several areas that special attention must be paid.
It is very important to follow the assembly instructions correctly and to make sure all parts are firmly
tightened. If the assembly instructions are not followed correctly, the treadmill could have frame parts that
are not tightened and will seem loose and may cause irritating noises. There should be no side-to-side play
in the console masts or any forward and back play in the console assembly or handlebars. If there is any
play in these areas, the treadmill has not been properly assembled. To prevent damage to the treadmill, the
assembly instructions must be reviewed and corrective actions should be taken.

your floor. Take CAUTION when handling and transporting this unit. Never open box when it is on its side.
