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 

Your treadmill, like any other type of sophisticated
electronic equipment, can be seriously damaged by
sudden voltage changes in your homeÕs 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 supressor, see your local
PROFORM dealer or call 1-800-366-7278 and order
part number 14657.

Use only a single-outlet surge 

suppressor that is UL 1449 listed as a transient voltage
surge suppressor (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.

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
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.

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. 

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.

DANGER:

Improper connection

of the equipment-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 productÑif it will
not fit the outlet, have a proper outlet 
installed by a qualified electrician.
