OPERATION AND ADJUSTMENT

THE PRE-LUBRICATED WALKING BELT

Your treadmill features a walking belt coated with high-

performance lubricant. IMPORTANT: Never apply sil-

icone spray or other substances to the walking

belt or the walking platform. 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 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 PROFORM dealer or call the toll-free

telephone number on the front cover of this man-

ual and order part number 146148, or see your local

electronics store.

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 result

in damage to the control system of the treadmill. If

the control system is damaged, the walking belt

may change speed, accelerate 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

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

GFCI-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. 

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 product—if it will

not fit the outlet, have a proper outlet 

installed by a qualified electrician.
