surface that blocks air openings. To protect the floor or carpet from damage, place a mat under the
treadmill.
•When choosing a location for the treadmill make sure that the location and position permit access to a plug.
•Keep the treadmill indoors, away from moisture and dust. Do not put the treadmill in a garage or covered
patio, or near water.
•Do not operate the treadmill where aerosol products are used or where oxygen is being administered.
•Keep children under the age of 12 and pets away from the treadmill at all times.
•The treadmill should not be used by persons weighing more than 350lbs (160kgs)
•Never allow more than one person on the treadmill at a time. Wear appropriate exercise clothing when
using the treadmill. Do not wear loose clothing that could become caught in the treadmill. Athletic support
clothes are recommended for both men and women. Always wear athletic shoes. Never use the treadmill
with bare feet, wearing only stockings, or in sandals.
•When connecting the power cord, plug the power cord into a grounded circuit. No other appliance should
be on the same circuit.
•Always straddle the belt and allow it to start moving before stepping onto the belt.
•Always examine your treadmill before using to ensure all parts are in working order.
•Allow the belt to fully stop before dismounting.
•Never insert any object or body parts into any opening.

POWER REQUIREMENTS
Power Requirements:
IMPROPER CONNECTION OF THE EQUIPMENT GROUNDING CONNECTOR CAN RESULT IN A RISK OF AN
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.
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 120VAC, 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 120-volt circuit, and has a grounding plug that looks like the plug illustrated in the
drawing below.

STABILIZER ADJUSTMENT
How to level the treadmill:
An uneven floor or improper stabilizer level can cause the treadmill to wobble during use as well as the incline
adjustment to function incorrectly. Please follow the procedure described below to make sure the treadmill stabilizer
is adjusted correctly prior to use. You may need the assistance of another person to perform this adjustment.
1. There are four stabilizers and two
cushions located on the underside
of the treadmill as shown in drawing
1. These all need to sit firmly on
the floor to prevent the treadmill
from wobbling during use.
1. Four stabilizers towards the rear and two cushions at the front.
2. Inspect each side of the treadmill
base frame. The treadmill should
sit on the floor with all four
stabilizers and both cushions
resting firmly on the floor as shown
in drawing 2. Shake the
handlebars back and forth to check
if they are resting firmly on the floor.
If they are not, tilt the treadmill to
one side to adjust the stabilizers as
shown in drawing 3. Simply turn
the stabilizers like a screw to adjust
their heights. Repeat this until the
treadmill sits firmly on the floor.
2. Check position of stabilizers and cushions.
3. Tilt treadmill to access stabilizers.
