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 300 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

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

treadmill.  
Remember to take the time to perform the stretching exercises provided on Page 6 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.  
KEYS recommends a sealed water bottle for beverages consumed while using the treadmill.

Warm Up Exercises  
EXERCISE GUIDELINES  
WARNING! Before beginning this or any exercise program, you should consult your physician. This is espe-  
cially 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 mus-  
cles 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 for-  
ward from your hips. Allow your back and shoulders to  
relax as you reach down toward your toes as far as pos-  
sible. 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 tendons, 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.

Moving  
See Figure 2  
CAUTION! TO AVOID THE RISK OF INJURY, NEVER ATTEMPT TO MOVE THE TREADMILL WHILE IT IS IN THE  
UNFOLDED OPERATING POSITON. TO REDUCE THE POSSIBILITY OF INJURY WHILE LIFTING, BEND YOUR  
LEGS AND KEEP YOUR BACK STRAIGHT. AS YOU RAISE THE TREADMILL, LIFT USING YOUR LEGS, NOT  
YOUR BACK. IN ORDER TO RAISE OR LOWER THE TREADMILL SAFELY, YOU MUST BE ABLE TO LIFT 45  
POUNDS (20KG). IT IS SUGGESTED YOU ALWAYS USE THE AID OF A SECOND PERSON WHEN MOVING THE  
TREADMILL.  
With the treadmill in the folded locked position (safety latch is engaged), grasp the handrails and place one foot on the base as  
shown in the photo below. Next, with a firm grasp on handrails, place one foot on the center of the base crossbar and carefully  
tilt the treadmill back until it rolls freely on the wheels. Using extreme caution, move the treadmill to the desired location. To  
set the treadmill down, place one foot on the center of the base crossbar and carefully lower treadmill onto base in resting  
position. Do not attempt to move the treadmill over an uneven or rough surface.

Power Requirements  
NG!  
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 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 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.

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 or 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, 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 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 re-  
tailer 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 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.

Troubleshooting Guide  
Treadmill will not start.  
1) Is the Safety Key inserted into the Treadmill Console?  
2) Make sure the power cord is plugged into a surge protector, the surge protector is plugged into a  
properly grounded outlet, and the surge protector is turned on. (Refer to “Power Requirements” on  
page 8)  
3) Check the circuit breaker located on the front of the treadmill. If the switch protrudes, it has tripped.  
Wait five minutes and then press the switch back in.  
4) Check the house electrical breaker box and the circuit breaker for the room the treadmill is located in.  
If it has tripped, reset or have an electrician replace the breaker in home.  
5) Have an electrician check for inadequate voltage at the outlet.

Wait five minutes and then press the switch back in.  
2) Check the house electrical breaker box and the circuit breaker for the room the treadmill is located in.  
If it has tripped, reset or have an electrician replace the breaker in home.

1) Check to make sure the treadmill is securely plugged into an UL-listed surge protector, rated at 15  
amps, with a 14-gauge cord of five feet or less and the surge protector is securely plugged into the  
outlet.  
2) If treadmill still will not operate, please call Keys Technical Service at (888) 340-0482.
