OPERATION AND ADJUSTMENT
THE PERFORMANT LUBE TM WALKING BELT
Your treadmill features a walking belt coated with
PERFORMANT LUBE TM, a high-performance lubricant.
IMPORTANT: Never apply silicone spray or other
substances to the walking belt or the walking plat-
form. Such substances will deteriorate the walking
belt and cause excessive wear.
HOW TO PLUG IN THE POWER CORD
A, DANGER: Improper connection
of the equ ipment-grounding conductor can
result in an increased risk of electric shock.
Check with a qualified electrician or service-
man 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.
Your treadmill, like any other type of sophisticated
electronic equipment, can be seriously damaged by
sudden voltage changes in your home's power.
Voltage surges, spikes, and noise interference can
result from weather conditions or from other appliances
being turned on or off. To decrease the possibility of
your treadmill being damaged, always use a surge
suppressor with your treadmill (see drawing 1 at
the right). To purchase a surge suppressor, see
your local NordicTrack dealer or call 1-800-806-
3651 and order part number 146148.
an equipment-grounding conductor and a grounding
plug. Plug the power cord into a surge suppressor,
and plug the surge suppressor into an appropriate
outlet that is properly installed and grounded in
accordance with all local codes and ordinances.
Important: The treadmill is not compatible with
GFCl-equipped outlets.
This product is for use on a nominal 120-volt circuit,
and has a grounding plug that looks like the plug illus-
trated in drawing 1 below. A temporary adapter that
looks like the adapter illustrated in drawing 2 may be
used to connect the surge suppressor to a 2-pole
receptacle as shown in drawing 2 if a properly
grounded outlet is not available.

"_,J... Grounding Pin
Ground_rd°o_ing P_
Outlet Box
Adapter
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
monitoring light on the surge suppressor to indi-
cate whether it is functioning properly. Failure to
use a properly functioning surge suppressor could
result in damage to the control system of the
treadmill. If the control system is damaged, the
walking belt may change speed or stop unexpect-
edly, which may result in a fall and serious injury.
This product must be grounded. If it should malfunc-
tion or break down, grounding provides a path of least
resistance for electric current to reduce the risk of elec-
tric shock. This product is equipped with a cord having
Metal Screw
The temporary adapter should be used only until a
properly grounded outlet (drawing 1) 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. Some 2-pole receptacle outlet box
covers are not grounded. Contact a qualified elec-
trician to determine if the outlet box cover is
grounded before using an adapter.

FEATURES OF THE CONSOLE
The advanced console offers a selection of features
designed to help you get the most from your exercise.
When the manual mode of the console is selected, the
speed and incline of the treadmill can be changed with
a touch of a button. As you exercise, the console will
provide continuous exercise feedback. You can even
measure your heart rate using the handgrip pulse sen-
sor. And for a total-body workout, the included hand
weights can be used as you walk on the treadmill.
Twenty-seven preset workout programs are also offered.
Each program automatically controls the speed and
incline of the treadmill to give you an effective workout.
You can even create custom workout programs and
store them in memory for future use.
In addition, the console offers a fitness test program
that measures your relative fitness level, and a pulse-
driven program that automatically adjusts the speed
and incline of the treadmill to keep your heart rate near
a target level during your workout. Note: The fitness
test program and the pulse-driven program require the
use of an optional chest pulse sensor (see page 24).
