OPERATION AND ADJUSTMENT
HOW TO PLUG IN THE POWER CORD
Your treadmill, like other electronic equipment, can be
damaged by sudden voltage changes in your home’s
power. To decrease the risk of damaging your
treadmill, always use a surge suppressor with your
treadmill (see drawing 1 at the right). To purchase
a surge suppressor, see precaution 12 on page 3.
Use only a single-outlet surge suppressor that is
UL 1449 listed as a transient voltage surge sup-
pressor (TVSS). The surge suppressor must have
a UL suppressed voltage rating of 400 volts or less
and a minimum surge dissipation of 450 joules.
The surge suppressor must be electrically rated for
120 volts AC and 15 amps. There must be a moni-
toring light on the surge suppressor to indicate
whether it is functioning properly. Failure to use a
properly-functioning surge suppressor could dam-
age the control system of the treadmill (see precau-
tion 13 on page 3).
This product must be grounded. If it should mal-
function or break down, grounding provides a path
of least resistance for electric current to reduce the
risk of electric shock. This product’s power cord has
an equipment-grounding conductor and a grounding
plug. Plug the power cord into a surge suppressor,
and plug the surge suppressor into an appropri-
ate outlet that is properly installed and grounded
in accordance with all local codes and ordinances.
IMPORTANT: The treadmill is not compatible with
GFCI-equipped outlets and may not be compatible
with AFCI-equipped outlets.
This product is for use on a nominal 120-volt circuit
(see drawing 1). A temporary adapter may be used to
connect the surge suppressor to a 2-pole receptacle if
a properly-grounded outlet is not available (see
drawing 2).
The temporary adapter should be used only until a
properly-grounded outlet (see drawing 1) can be in-
stalledbyaqualiedelectrician.
The green-colored rigid ear, lug, or the like extend-
ing from the adapter must be connected to a perma-
nent ground such as a grounded outlet box cover.
The adapter must be held in place by a metal screw.
Some 2-pole receptacle outlet box covers are not
grounded. Contact a qualied electrician to deter-
mine if the outlet box cover is grounded before
using an adapter.
DANGER: Improper connec-
tion of the equipment-grounding conductor
increases the risk of electric shock. Check
with a qualied electrician or serviceman if
you are unsure whether the product is prop-
erly grounded. Do not modify the plug—if it
will not t the outlet, have a proper outlet in-
stalled by a qualied electrician.
