Moving Instructions  
Caution! To avoid the risk of injury, never attempt to move the treadmill while it is in  
the unfolded operating position. 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 handrail  
and place one foot on the center of the base crossbar as shown in the photo below. Next, with  
a firm grasp on the handrail, 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.  
Note: The treadmill pictured below may not be identical to your particular model.

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 plug 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 dedicated 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 appro-  
priate outlet that is properly installed and grounded in accordance with all local codes and ordi-  
nances. Do not connect other equipment to the surge protector or this could cause permanent  
damage to your treadmill.  
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.

Monitoring Your Heart Rate  
Monitoring Your Heart Rate  
To obtain the greatest cardiovascular benefits from your exercise workout, it is important to  
work within your target heart rate zone. The American Heart Association (AHA) defines this tar-  
get as 60%-75% percent of your maximum heart rate.  
Your maximum heart rate may be roughly calculated by subtracting your age from 220. Your  
maximum heart rate and aerobic capacity naturally decreases as you age. This may vary from  
one person to another, but use this number to find your approximate effective target zone. For  
example, the maximum heart rate for an average 40 year-old is 180 bpm. The target heart  
rate zone is 60%-75% of 180 or 108-135 bpm. See Fitness Safety below.  
Before beginning your workout, check your normal resting heart rate. Place your fingers lightly  
against your neck, or against your wrist over the main artery. After finding your pulse, count  
the number of beats in 10 seconds. Multiply the number of beats by six to determine your  
pulse rate per minute. We recommend taking your heart rate at these times; at rest, after  
warming up, during your workout and two minutes into your cool down, to accurately track  
your progress as it relates to better fitness.  
During your first several months of exercising, the AHA recommends aiming for the lower part  
of the target heart rate zone-60%, then gradually progressing up to 75%.  
According to the AHA, exercising above 75% of your maximum heart rate may be too strenu-  
ous unless you are in top physical condition. Exercising below 60% of your maximum will result  
in minimal cardiovascular conditioning.  
Check your pulse recovery rate – If your pulse is over 100 bpm five minutes after you stop  
exercising, or if it’s higher than normal the morning after exercising, your exertion may have  
been too strenuous for your current fitness level. Rest and reduce the intensity next time.  
Fitness Safety The target heart rate chart indicates average rate zones for different ages. A  
variety of different factors (including medication, emotional state, temperature and other condi-  
tions) can affect the target heart rate zone that is best for you. Your physician or health care  
professional can help you determine the exercise intensity that is appropriate for your age and  
condition.  
(MHR) = Maximum Heart Rate  
(THR) = Target Heart Rate  
220 - age = maximum heart rate (MHR)  
MHR x .60 = 60% of your maximum heart rate.  
MHR x .75 = 75% of your maximum heart rate.  
For example, if you are 30 years old, your calculations will be as  
follows:  
220 - 30 = 190  
190 x .60 = 114 (low end or 60% of MHR)  
190 x .75 = 142 (high end or 75% of MHR)  
30 year-old (THR) Target Heart Rate would be 114-142  
See Heart Rate Table (on next page) for additional calculations.

Warm Up Exercises  
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 (Image not Shown)  
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.

Belt Adjustment  
WARNING! Do not over-tighten 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 toward the center. Repeat the above proce-  
dure 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.

(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 toward the center. Repeat the above proce-  
dure until the walking belt is centered. It may be neces-  
sary to set walking belt tension once you have completed  
this procedure if the belt feels like it is slipping while walk-  
ing. Refer below to the “Walking Belt Slipping” instructions.  
Diagram 2  
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.  
Diagram 3  
Note: Turning the hex key clockwise brings the rear roll-  
ers and belt towards you.  
Turning the hex key counter clockwise pushes the rear  
roller and belt away from 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 unit will extend the life of your unit.  
WARNING! To prevent electrical shock, be sure the power to the treadmill is OFF and the unit is  
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, lubrication is needed.  
Keys Fitness recommends “Lube N Walk” for cleaning and lubricating the treadmill belt and  
deck. Ask your retailer or call Keys Fitness at 888-340-0482.  
TO APPLY LUBRICANT TO THE WALKING BOARD  
1.) Take foam wand applicator, without lube, and insert it in between the walking belt and deck,  
exposing the two plastic tabs at either end of the walking belt. Take both tabs and run the  
wand back and fort along the entire length of your deck. Remove the applicator and prepare for  
lubrication.  
2) Apply about a dime's worth of lubrication onto the side of the applicator wand hat was not  
used for removing dirt and debris (step 1). You can add more or less lubricant, depending on  
your lubrication schedule.  
3) Insert the wand between the walking belt and deck, exposing the two white plastic tabs at  
either end of the walking belt.  
4) Take both of the tabs and run the wand back and forth along the entire length of your deck.  
You are done until your next scheduled lubrication date.  
5) 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.
