HOW TO USE THE TREADMILL

HOW TO CONNECT THE POWER CORD

Use a Surge Suppressor

Your treadmill, like other electronic equipment, can be 

damaged by sudden voltage changes in your home’s 

power. Voltage surges, spikes, and noise interference 

can result from weather conditions or from other appli-

ances being turned on or off. To decrease the risk of 

damaging the treadmill, always use a surge sup-

pressor (A) with the treadmill. To purchase a surge 

suppressor, see precaution 14 on page 3.

Use only a surge suppressor (A) that is UL 1449 listed 

as a transient voltage surge suppressor (TVSS). The 

surge suppressor must have a UL suppressed volt-

age rating of 400 volts or less and a minimum surge 

dissipation of 450 joules. The surge suppressor must 

also be electrically rated for 120 volts AC and 15 

amps. There must be a monitoring light on the surge 

suppressor to indicate whether it is functioning prop-

erly. Failure to use a properly functioning surge 

suppressor could result in damage to the control 

system of the treadmill and serious injury to users.

Plug in the Power Cord

The treadmill 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. The treadmill power cord (B) has a plug with 

a grounding pin (C) (see drawing 1 on this page).

Plug the power cord (B) into a surge suppressor 

(A), and plug the surge suppressor into an appropri-

ate outlet (D) that is properly installed and grounded 

in accordance with all local codes and ordinances. 

The outlet must be on a nominal 120-volt circuit 

capable of carrying 15 or more amps. To avoid 

overloading the circuit, do not plug other electrical 

devices, except for low-power devices such as cell 

phone chargers, into the surge suppressor or into 

an outlet on the same circuit. IMPORTANT: If the 

treadmill is connected to an AFCI-equipped outlet 

and your circuit breaker trips repeatedly when the 

treadmill is used, see the front cover of this manual 

to purchase an arc filter.

A temporary 

adapter (E) 

may be used 

to connect the 

surge sup-

pressor (A) 

to a 2-pole 

receptacle (F) 

if a properly 

grounded outlet 

is not available.

The lug (G) or wire extending from the adapter must 

be connected with a metal screw (H) to a permanent 

ground such as a properly grounded outlet box cover. 

Some 2-pole receptacle outlet box covers are not 

grounded. Before using an adapter, contact a quali-

fied electrician to determine whether the outlet box 

cover is grounded. The temporary adapter should 

be used only until a properly grounded outlet can 

be installed by a qualified electrician.

      DANGER:

Improper connection 

of the power cord increases the risk of elec-

tric shock. Do not modify the plug—if it will 

not fit an outlet, have a proper outlet installed 

by a qualified electrician. If you are unsure 

whether the treadmill is properly grounded, 

contact a qualified electrician.
