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 does not fit into 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.

Workout Information  
Frequency, Intensity, Time, Target Heart Rate Zone  
The exercise practices include four major variables: frequency, intensity, time, target heart rate  
zone. A continuous workout will help to improve your cardiovascular functions and increase the  
ability of your muscles to obtain the oxygen and nutrition. A good workout provides a greater  
advantage to extend the endurance of muscle and body flexibility.  
Frequency: How Often Should You Exercise  
Three to five times a week is highly suggested to improve your cardiovascular and muscle fit-  
ness.  
Intensity: How Hard Should You Exercise  
The intensity of an exercise is reflected in your heart rate. Exercise must be sufficient to  
strengthen your heart muscle and condition your cardiovascular system. Only your doctor or  
an authorized coach can prescribe the target training heart range appropriate for your particular  
needs and physical condition.  
Start with an exercise that stimulates you to breathe more deeply. Alternate periods of mod-  
erate and easy exercise to help your body adapt to new levels of exertion without unnecessary  
strain. The inability to maintain a smooth, rhythmic motion is a sign that your pace and/or your  
elevation is too high . If you feel out of breath before you have exercised 12 minutes, you are  
probably overdoing it.  
As your fitness level improves, you will need to increase your workload to reach your target  
heart rate. The first increase may be necessary after two to four weeks of regular exercise.  
Never exceed your target heart rate zone.  
Weight Management  
Consistent aerobic exercise will help you change your body composition by lowering your per-  
centage of body fat. For weight control, how long and how often you exercise is more important  
than how hard you exercise.  
Exercise at least four to five times a week.  
Reach and maintain 60-75% of your maximum heart rate with moderate exercise.  
Exercise for 30-45 minutes at 60-65% of your target heart rate.  
Here are some tips to achieve your weight management goal.  
Consume most of your dietary calories at breakfast and lunch, and eat a light dinner.  
Do not eat anything near the bedtime.  
Moderate exercise will help suppress your appetite.  
Take regular breaks and rests to help increase metabolism.  
Warning!  
If you have any questions or concerns about your target heart rate, consult your physician.  
Medications may affect your heart rate. Stop exercise if: you feel faint or dizzy, acute illness  
(cold or fever), any pain or tightness in your chest, an irregular heartbeat, of if you exceed  
your maximum heart rate set by your physician.

Workout Information  
Exercise Practice Procedures  
Warm-Up  
Workout  
Cool Down  
A good warm-up will help you perform better and will decrease the aches and pains. The warm-  
up prepares your muscles for exercise and allows your oxygen supply to ready itself for what is  
to come. Experience tells us that muscles perform best when they are warmer than normal body  
temperature. This normally takes about 5-10 minutes when you begin to perspire on your brow  
and breathe more deeply.  
Note: The older you are, the longer your warm-up period should be.  
Workout: Brisk and Rhythmic Exercise  
A workout trains your heart, lungs, and muscles to be more efficient. Increase exercise in  
response to your heart rate to train and strengthen your cardiovascular system. Concentrate on  
moving your arms and legs smoothly. Walking naturally and avoid jerking motions like pulled  
muscles, sprained joints, and loss of balance.  
If you cannot sustain 12 continuous minutes in your target heart rate zone, then, exercise  
several times a day to get into habit. Try to reach and maintain 60-65% of your maximum  
heart rate. Alternate exercise with periods of rest until you can sustain 12 continuous minutes  
of exercise at 60-65% of your maximum heart rate. Best start with a target 3-4 minutes, then,  
increase it gradually.  
If you can sustain 12 but not 20 continuous minutes of exercise in your target heart rate  
zone:  
Exercise 3-5 days a week. Rest at least two days per week.  
Try to reach and maintain 65-70% of your maximum heart rate with moderate rhythmic  
exercises.  
Begin with 12 continuous minutes. Increase your time by one to two minutes per week  
until you can sustain 20 continuous minutes.  
If you can sustain 20 minutes continuously in your target heart rate zone, begin to increase the  
length and intensity of your workout:  
Exercise 4-6 days a week or on alternate days.  
Try to reach and maintain 70~85% of your maximum heart rate with moderate to some-  
what hard exercise.  
Exercise 20-30 minutes.  
WARNING: These strategies are intended for average healthy adults. If you have pain or tight-  
ness in your chest, an irregular heartbeat, shortness of breath or you feel faint or have any dis-  
comfort when you exercise, STOP. Consult your physician before continuing. Remember, every  
workout should begin with warmup and finished with cool down.  
Cool down: Slow and Relaxed Exercise  
The cool down allows your body’s cardiovascular system to gradually return to normal and  
should be roughly 5-10 minutes. Lower your exercise intensity gradually, and when your heart  
rate has returned below 110 beats per minutes, you can end your workout.

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 tread-  
mill 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 procedure until  
the walking belt is centered. It may be necessary to set  
walking belt tension once you have completed this proce-  
dure if the belt feels like it is slipping while walking. Refer  
below to the “Walking Belt Slipping” instructions.  
Diagram 1  
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 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.

Warranty Information  
Residential and Personal Use Limited Warranty  
PLEASE READ THESE WARRANTY TERMS AND CONDITIONS FULLY AND CAREFULLY BEFORE USING YOUR KEYS FITNESS EQUIPMENT. BY  
USING THE EQUIPMENT, YOU ARE CONSENTING TO BE BOUND BY THE FOLLOWING TERMS AND CONDITIONS.  
Frame: Lifetime  
Drive Motor: 15 yrs  
Parts: 1 yr  
Labor: 1 Yr  
Missing/Cosmetic Parts: 30 Days  
Keys, as a manufacturer, reserves the right to replace the Product with  
a Factory-Reconditioned Product that meets or exceed standards  
comparable to those of the replaced Product.  
Limited Warranty  
This Limited Warranty applies in the United States and Canada to  
Products manufactured or distributed by Keys Fitness Products, L.P.  
under the Keys Fitness (“Keys”) brand name (as used herein, the  
“Product” or “Products”). The warranty period to the original  
purchaser is listed above, and commences on the date of original  
purchase of the product, unless otherwise authorized by Keys. Keys  
warrants that the Product purchased from Keys or from an  
authorized Keys Fitness reseller “dealer” (for residential or personal  
use only, unless otherwise authorized by Keys in writing), is free  
from defects in Materials and Workmanship relevant to the  
functionality of the Product at initial startup, under normal use, and  
during the applicable warranty period, unless otherwise determined  
by Keys.  
The warranty covering the replacement Product shall expire on the  
date the original warranty for the replaced Product would have expired,  
unless otherwise determined by Keys. Note that a non-defective  
Product may not be eligible for return or replacement after 30 days from  
date of purchase. If opting to return a non-defective product to Keys, as  
the manufacturer, within 30 days from date of purchase (in its original  
packaging and with its original proof of purchase), the “customer” shall  
be subject to a 15% restocking fee and pre-paid freight charges accrued  
as a result of the return, unless otherwise determined by Keys.  
Conditions and Restrictions  
This warranty DOES NOT (A) cover shipping and handling charges,  
export taxes, custom duties and taxes, or any other charges associated  
with transportation of the parts or Product, beyond the initial courtesy  
period of 60 days from original date of purchase of the Product; (B)  
extend to Products not purchased from Keys or from an authorized  
Keys reseller; (C) extend to Products purchased from online auction  
sites; (D) cover any extended, additional, or third party warranties if  
not offered exclusively by Keys in writing; (E) cover Products installed  
at fee based facilities/commercial environments (gyms, homes used as  
wellness centers, etc.); (F) cover Products installed in light institutional  
environments (non fee-based facilities with total Product use time not  
exceeding 5 hours daily, to include for example, and not be way of  
limitation, fire houses, police departments, rehab centers, hospitals,  
clinics, apartment complexes, club houses, etc.); (G) cover service calls  
to correct installation, perform maintenance, or instruct owners on how  
to use the equipment; or (H) cover a Product on which the serial  
number has been purposefully or accidentally defaced or removed and  
there is no proof of purchase available (if serial number is applicable),  
unless authorized by Keys in writing or otherwise stated on this  
warranty.  
This warranty excludes expendable parts if the primary cause for a  
warranty claim is wear. Expendable parts pertain to components on  
the Product that are prone to normal wear and tear. These items  
vary by Product, and may include (but not be limited to) hand grips,  
skid pads, walking belts, walking decks, poly-v belts, console  
overlays, toggle switch/button overlays, (luster free or dull) ekg  
plates, decals, and any other items that are not essential to the  
operation of the Product, unless otherwise determined by Keys.  
This warranty extends only to you, the original purchaser. It is not  
transferable to anyone who subsequently purchases (or receives as a  
gift) the Product from you. Your sales receipt, showing the  
date/place of purchase and serial number (if applicable) of the  
Product, is your proof of purchase, and may be required by Keys any  
time a warranty parts or service claim is made or if no warranty  
record exists for the product.  
Exclusive Remedies  
During the warranty period listed above, Keys will repair a Product  
by correcting any minor issues (either by phone or online support)  
that might be causing the Product failure. Should a technical service  
and support representative be unable to correct the issue, Keys  
may replace the parts (with new parts or at the option of Keys, with  
serviceable used parts, that are equivalent to new parts in  
performance) that become defective, malfunction, or otherwise fail  
to conform to this Limited Warranty under normal use.  
This Limited Warranty becomes void for Products that have been  
damaged or rendered defective as a result of (a) accident, misuse, or  
abuse (including but not limited to exceeding the Keys listed, maximum  
weight limit); (b) use of parts not manufactured or sold by Keys; (c)  
modification of the Product; (d) normal wear and tear; (e) operation on  
incorrect power supplies; (f) ***failure to perform (or performing  
improper) maintenance; (g) service by anyone other than Keys, or an  
authorized Keys warranty service provider; (h) floods, fires,  
earthquakes, lightning strikes, power surges, and other unavoidable  
acts of nature; (j) residential mis-wires; or (k) incorrect setup,  
installation, or assembly. Should any Product (submitted for warranty  
parts replacement) be found ineligible under the terms outlined on this  
warranty, an estimate for parts purchase (if available) can be furnished  
at your request.  
Replacement parts shall be warranted for 30 days from the shipment  
reception date or through the end of the ‘replaced’ part warranty  
period, whichever is longer. Any replacement parts, required past  
the warranty period listed above, shall be subject to purchase at  
retail price, plus any added shipping and handling charges associated  
to the delivery of the part. Note that replacement parts may be  
available only through the **lifetime (as defined) of the Product. In  
conforming to this warranty, Keys (as the manufacturer) reserves  
the right to change manufacturers or vendors of any part to cover  
the existing warranty.  
*Parts is herein defined exclusively, for all intents and purposes, and  
pertaining to this Limited Manufacturer Warranty, as components or Materials  
essential to the functionality of the Product.  
**Lifetime of a Product, is herein defined exclusively, for all intents and  
purposes, and pertaining to this Limited Manufacturer Warranty, as the time  
period 7 years beyond the end of production cycle of a Product in question.  
Keys may also provide service (if deemed necessary and if applicable)  
at no charge to you during (and not to exceed) the service warranty  
period listed above, in an attempt to repair the Product. Should the  
Product require service at your request or out of the limited warranty  
period, Keys can furnish contact information for local (to your area)  
Keys authorized service providers. Service quotes, costs, and  
scheduling will be strictly dependent on service provider rates and  
mutual (consumer/provider) service agreements. Keys is not  
responsible for any service repair costs accrued through the use of  
authorized Keys service providers dispatched at your request or out  
of the limited warranty period (without written consent from Keys),  
and beyond the limitations outlined on this warranty.  
*** Includes proper lubrication of the running deck and walk belt area, as  
indicated in the owner’s manual.  
Disclaimer and Release  
EXCEPT AS EXPRESSLY SET FORTH IN THIS WARRANTY, KEYS MAKES NO  
OTHER WARRANTIES, EXPRESSED OR IMPLIED, INCLUDING ANY IMPLIED  
WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR  
PURPOSE. KEYS EXPRESSLY DISCLAIMS ALL WARRANTIES NOT STATED IN  
THIS LIMITED WARRANTY. ANY IMPLIED WARRANTIES THAT MAY BE  
IMPOSED BY LAW ARE LIMITED TO THE TERMS OF THIS LIMITED WARRANTY.  
NEITHER KEYS NOR ANY OF ITS AFFILIATES SHALL BE RESPONSIBLE FOR  
INCIDENTAL OR CONSEQUENTIAL DAMAGES. SOME STATES DO NOT ALLOW  
LIMITATIONS ON IMPLIED WARRANTIES OR THE EXCLUSION OR  
LIMITATION OF INCIDENTAL OR CONSEQUENTIAL DAMAGES, SO THE ABOVE  
LIMITATIONS OR EXCLUSIONS MAY NOT APPLY TO YOU. THIS LIMITED  
WARRANTY GIVES YOU SPECIFIC LEGAL RIGHTS AND YOU MAY ALSO HAVE  
OTHER RIGHTS THAT MAY VARY FROM STATE TO STATE. THIS IS THE ONLY  
EXPRESS WARRANTY APPLICABLE TO KEYS-BRANDED PRODUCTS. KEYS  
NEITHER ASSUMES NOR AUTHORIZES ANYONE TO ASSUME FOR IT ANY  
OTHER EXPRESS WARRANTY.  
Replacements and Returns  
If after a reasonable number of attempts, a defect has not been  
repaired (or the Product is deemed non-repairable by Keys technical  
service and support staff), Keys, based on a case by case review,  
may opt to replace the Product, or recommend an alternate  
resolution, such as a warranty buy-out (Product cost, subject to  
deduction of a reasonable charge for usage) or a credit.
