IMPORTANT PRECAUTIONS

1. Before beginning any exercise program, con-

sult your physician. This is especially impor-
tant for persons over the age of 35 or persons
with pre-existing health problems.

2. It is the responsibility of the owner to ensure

that all users of this treadmill are adequately
informed of all warnings and precautions.

3. Use the treadmill only as described.

4. Place the treadmill on a level surface, with at

least 8 ft. (2.4 m) of clearance behind it and 2
ft. (0.6 m) on each side. Do not place the
treadmill on any surface that blocks air open-
ings. To protect the floor or carpet from dam-
age, place a mat under the treadmill. 

5. Keep the treadmill indoors, away from mois-

ture and dust. Do not put the treadmill in a
garage or covered patio, or near water. 

6. Do not operate the treadmill where aerosol

products are used or where oxygen is being
administered. 

7. Keep children under the age of 12 and pets

away from the treadmill at all times.

8. The treadmill should not be used by persons

weighing more than 250 lbs. (113 kg). 

9. Never allow more than one person on the

treadmill at a time. 

10. Wear appropriate exercise clothes when

using the treadmill. Do not wear loose clothes
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. 

11. When connecting the power cord (see page 12),

plug the power cord into a surge suppressor

(not included) and plug the surge suppressor
into a grounded circuit capable of carrying 15
or more amps. No other appliance should be on
the same circuit. Do not use an extension cord. 

12. Use only a single-outlet surge suppressor that

meets all of the specifications described on
page 12. To purchase a surge suppressor, see
your local SEARS store or call the telephone
number on the back cover of this manual and
order part number 146148, or see your local
electronics store.

13. Failure to use a properly functioning surge

suppressor could result in damage to the con-
trol system of the treadmill. If the control sys-
tem is damaged, the walking belt may change
speed, accelerate, or stop unexpectedly,
which may result in a fall and serious injury.

14. Keep the power cord and the surge suppres-

sor away from heated surfaces.

15. Never move the walking belt while the power

is turned off. Do not operate the treadmill if
the power cord or plug is damaged, or if the
treadmill is not working properly. (See TROU-
BLESHOOTING on page 19 if the treadmill is
not working properly.)

16. Read, understand, and test the emergency

stop procedure before using the treadmill (see
HOW TO TURN ON THE POWER on page 13).

17. Never start the treadmill while you are stand-

ing on the walking belt. Always hold the
handrails while using the treadmill.

18. The pulse sensor is not a medical device.

Various factors, including your movement,
may affect the accuracy of heart rate readings.
The pulse sensor is intended only as an exer-
cise aid in determining heart rate trends in
general.

WARNING:

To reduce the risk of serious injury, read all important precautions and in-

structions in this manual and all warnings on your treadmill before using your treadmill. Sears as-
sumes no responsibility for personal injury or property damage sustained by or through the use of
this product.
