SAFETY PRECAUTIONS AND TIPS  
It is the owner’s responsibility to ensure that all users of this treadmill have read the Owner’s Manual and  
are familiar with warnings and safety precautions.  
This treadmill has a user maximum capacity of 275 pounds.  
The treadmill should only be used on a level surface and is intended for indoor use only. The treadmill  
should not be placed in a garage, patio, or near water and should never be used while you are wet. KEYS  
recommends a treadmill mat be placed under the treadmill to protect floor or carpet and for easier  
cleaning.  
Follow safety information in regards to plugging in your treadmill. Keep the power cord away from the  
incline wheels and do not run the power cord underneath your treadmill. Do not operate the treadmill with  
a damaged or frayed power cord.  
Wear comfortable, good-quality walking or running shoes and appropriate clothing. Do not use the  
treadmill with bare feet, sandals, socks or stockings.  
Always straddle the belt and allow it to start moving before stepping onto the belt.  
Hold on to handrails when adjusting speed, incline, or other controls.  
Always examine your treadmill before using to ensure all parts are in working order.  
Allow the belt to fully stop before dismounting.  
Pets should never be allowed near or on the treadmill.  
Do not leave children unsupervised near or on the treadmill.  
Never operate the treadmill where oxygen is being administered, or where aerosol products are being  
used.  
Never insert any object or body parts into any opening.  
For safety and to prevent damage to your treadmill, no more than one person should use the treadmill at a  
time.  
Always unplug the treadmill before cleaning and/or servicing. Service to your treadmill should only be  
performed by an authorized service representative, unless authorized and/or instructed by the  
manufacturer. Failure to follow these instructions will void the treadmill warranty.  
Never leave the treadmill unattended while it is running.

treadmill.  
Remember to take the time to perform the stretching exercises provided to avoid injury.  
Do not stand on the walking belt while pressing the Power button or Start/Stop button.  
Always adjust the speed of the treadmill in small increments as this treadmill is capable of high speeds.  
If you are taking medication, consult your physician to see if the medication will affect your exercise  
heart rate.  
If you have heart problems, you are not active, and/or are over the age of 35 years, do not use the pre-set  
treadmill programs or start an exercise program without first contacting and receiving approval from your  
physician.  
To avoid the risk of electrical shock, always keep the console dry. Do not spill liquids on the console.

Warm Up Exercises  
EXERCISE GUIDELINES  
WARNING! Before beginning this or any exercise program, you should consult your physician. This is es-  
pecially 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 ex-  
ercise 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 shoul-  
ders 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 op-  
posite 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 to-  
ward 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 re-  
lax. This will stretch your quadriceps and hip mus-  
cles.

Power Requirements  
ARNG!  
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 UL 1449 rating as a Transient Voltage Surge Suppressor (TVSS) with UL suppressed  
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 electrical 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.

Belt Adjustment and Tension  
WARNING! Do not overtighten rollers! This will cause  
premature roller bearing failure!  
Belt adjustment and tension performs two functions: adjustment for  
tension and centering. Your new treadmill comes pre-adjusted from  
the factory for tension and centering. Please follow the procedures  
below if the belt shifts to the left or right while walking:  
WALKING BELT IS SHIFTING TO THE LEFT (Diagram 1)  
First, turn treadmill on to run at 1 mph. Using the hex key provided,  
turn the left rear roller adjustment bolt ¼ turn in the clockwise  
direction. Next, run the treadmill at 2.5 mph. You should see the belt  
start to correct itself by moving back towards the center. Repeat the  
above procedure until the walking belt is centered. It may be  
necessary to set walking belt tension once you have completed this  
procedure if the belt feels like it is slipping while walking. Refer  
below to the “Walking Belt Slipping” instructions.  
WALKING BELT IS SHIFTING TO THE RIGHT (Diagram 2)  
First, turn the treadmill on to run at 1 mph. Using the hex key  
provided, turn the right rear roller adjustment bolt ¼ turn in the  
clockwise direction. Next, run the treadmill at 2.5 mph. You should  
see the belt start to correct itself, moving back towards the center.  
Repeat the above procedure until the walking belt is centered. It  
may be necessary to set walking belt tension once you have  
completed this procedure if the belt feels like it is slipping while  
walking. Refer below to the “Walking Belt Slipping” instructions.  
WALKING BELT IS SLIPPING DURING USE (Diagram 3)  
First, unplug the power cord from the surge protector. Using the  
hex key provided, turn both left and right rear roller adjustment bolts  
the same distance, usually a ¼ turn in the clockwise direction. Plug  
the power cord back into the surge protector and run the treadmill at  
2.5 mph. You should now walk on the belt to determine if the belt is  
still slipping. Repeat the above procedure until the walking belt is  
not slipping. The tension should be just tight enough not to slip.  
Turning the hex key counter clockwise brings the rear rollers  
and belt towards you.  
Turning the hex key clockwise pushes the rear roller and belt  
away form you.

Maintenance Instructions  
WARNING! Before performing any maintenance to your treadmill, always unplug the power cord from the  
surge protector.  
CLEANING:Routine cleaning of your 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. Your treadmill should not have to be lubricated usually within the first year or 500 hours of  
use. If you have questions, call us at (888) 340-0482.  
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.  
Please use Lube ‘N Walk (can be purchased from your dealer or call the number on the front of the  
manual), or a non-petroleum based 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 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 4 seconds on each side.  
4) Allow the silicone to ‘set’ for one minute before using the treadmill.  
WARNING: Do not overlubricate the walking board. Excess lubricant should be wiped off with a  
clean towel.
