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

This treadmill can be seriously damaged by sudden voltage changes in your home’s electrical power. Voltage
spikes, surges and noise interference can result from weather conditions or from other appliances being turned on
or off. To reduce the possibility of treadmill damage, always use a surge protector (not included) with your
treadmill.
Surge protectors can be purchased at most hardware stores. The manufacturer recommends a single outlet
surge protector with a UL 1449 rating as a Transient Voltage Surge Suppressor (TVSS) with a UL suppressed
voltage rating of 400V or less and an electrical rating 110VAC, 15 amps.
This treadmill must be grounded to reduce the risk of electrical shock. Grounding provides a path of least
resistance for electric current, should the treadmill malfunction. This treadmill comes with an electrical cord having
an equipment-grounding conductor and a grounding plug. Always plug the power cord into a surge protector, and
plug the surge protector 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 110-volt circuit, and has a grounding plug that looks like the plug illustrated in
the drawing below. GFCI outlets and GFCI Circuit Breakers are NOT recommended for use on this product. GFCI
outlets and GFCI Circuit Breakers may cause this equipment to function improperly.

MAINTENANCE
CLEANING:
Routine cleaning of your treadmill will extend the product's life.
•Warning: To prevent electrical shock, be sure the power to the treadmill is OFF and the power cord
is unplugged from the wall electrical outlet before attempting any cleaning or maintenance.
•Important: Do not use abrasives or solvents to clean the treadmill. To prevent damage to the
computer, keep liquids away and keep it out of direct sunlight.
•After each workout: Wipe off the console and other treadmill surfaces with a clean, water
dampened soft cloth to remove excess perspiration.
•Weekly: Use of a treadmill mat is recommended for ease of cleaning. Dirt from your shoes contacts
the belt and eventually makes it to underneath the treadmill. Vacuum underneath treadmill once a
week.
DECK LUBRICATION:
The walking belt has been pre-lubricated at the factory. However, it is recommended that the walking board be
checked periodically for lubrication to ensure optimal treadmill performance. Your treadmill should not have to be
lubricated usually within the first 400 hours of use.
Every 2 months of operation lift the sides of the walking belt and feel the top surface of the walking board as far
as you can reach. If you feel signs of silicone, no further lubrication is required. If it feels dry to the touch, follow
the instructions below.
To purchase lubricant kit please contact Smooth Fitness 1-888-800-1167
To apply lubricant to the walking belt:
1. Position the walking belt so that the seam is located on top and in center of the walking board.
2. Insert the spray nozzle into the spray head of the lubricant can.
3. While lifting the side of the walking belt, position the spray nozzle between the walking belt and the board
approximately 6" from the front of the treadmill. Apply the silicone spray to the walking board, moving
from the front of the treadmill to the rear. Repeat this on the other side of the belt. Spray approximately
1/4 bottle (supplied with treadmill) each side..
4. Allow the silicone to "set" for 1 minute before using the treadmill.
Apply from front to back.
