Warm Up Exercises
6
EXERCISE GUIDELINES
WARNING! Before beginning this or any exercise program, you should consult your physician. This is
especially important for individuals over the age of 35 or individuals with pre-existing health problems.
Warming up prepares the body for the exercise by increasing circulation, supplying more oxygen to the
muscles and raising body temperature. Begin each workout with 5 to 10 minutes of stretching and light
exercise to warm up. The photos on this page show several forms of basic stretching you may perform
before your workouts. In order to achieve an adequate warm-up, perform each stretch three times.
TOE TOUCH STRETCH
Stand bending your knees slightly and slowly bend forward from your hips. Allow your
back and shoulders to relax as you reach down toward your toes as far as possible.
Hold for 15 counts, then relax. This will stretch your hamstrings, back of knees, and
back.
HAMSTRING STRETCH
Sit with one leg extended. Bring the sole of the opposite foot
toward you and rest it against the inner thigh of your extended leg.
Reach toward your toes as far as possible. Hold for 15 counts,
then relax. This will stretch your hamstrings, lower back, and
groin.
CALF/ ACHILLES STRETCH
With one leg in front of the other, reach forward and place your hands against a wall.
Keep your back leg straight and your back foot flat on the floor. Bend your front leg,
lean forward and move your hips toward the wall. Hold for 15 counts, then relax. To
cause further stretching of the Achilles tendon, bend your back leg as well. This will
stretch your calves, Achilles tendons, and ankles.
QUADRICEPS STRETCH
With one hand against a wall for balance, reach back and grasp one foot with your
other hand. Bring your heel as close to your buttocks as possible. Hold for 15
counts, then relax. This will stretch your quadriceps and hip muscles.
INNER THIGH STRETCH
Sit with the soles of your feet together and your knees outward. Pull your feet
toward your groin area as far as possible. Hold for 15 counts, then relax. This
will stretch your quadriceps and hip muscles.

IMPROPER CONNECTION OF THE EQUIPMENT GROUNDING CONNECTOR CAN
RESULT IN A RISK OF AN ELECTRIC SHOCK. CHECK WITH A QUALIFIED ELEC-
TRICIAN OR SERVICE MAN IF YOU ARE IN DOUBT AS TO WHETHER THE PROD-
UCT 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 out-
let surge protector with UL 1449 rating as a Transient Voltage Surge Suppressor (TVSS) with UL sup-
pressed voltage rating of 400V or less and an electrical rating of 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 electri-
cal cord with 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.

Maintenance Instructions
15
WARNING! Before performing any maintenance to your treadmill, always unplug the power cord from
the surge protector.
CLEANING
Routine cleaning of your Keys Fitness treadmill will extend the life of your treadmill. WARNING! To
prevent electrical shock, be sure the power to the treadmill is OFF and the unit unplugged from the wall
electrical outlet before attempting any cleaning or maintenance.
AFTER EACH WORKOUT: Wipe off the console and other treadmill surfaces with a clean, water
dampened soft cloth to remove excess perspiration. USE NO CHEMICALS.
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.
Every 30 days or 30 hours of operation, lift the sides of the walking belt and feel the top surface of the
walking board as far under 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.
KEYS recommends “Lube N Walk” for cleaning and lubricating the treadmill belt and deck. Ask your
retailer or call KEYS at 800-340-0482. You may also use silicone such as “Napa 8300” (available at most
stores).
TO APPLY LUBRICANT TO THE WALKING BOARD
1) Position the walking belt so that the seam is located on top and in the center of the center of the walk-
ing 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 4 seconds on each side.
4) Allow the silicone to ‘set’ for one minute before using the treadmill.
WARNING: Do not over-lubricate the walking board. Excess lubricant should be wiped off with a clean
towel.
