Before You Start 

Thank you for purchasing a KEYS treadmill!  This quality product you have chosen was 

designed to meets your needs for cardiovascular exercise.   

Before you start, please read the Owner’s Manual and become familiar with the 
operation of your new 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 50 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.   

Please review the following drawing below to familiarize yourself with the listed 
parts.  This manual covers several treadmills, so the one pictured below may not 
be identical to your particular model.
