Your treadmill is capable of reaching high speeds. Always start off using a slower speed and adjust the speed in small increments to reach a higher speed level. Never leave the treadmill unattended while it is running. When not in use, remove the safety key, turn the on/off switch to off and unplug the power cord. Make sure to follow the MAINTENANCE schedule in this guide to maintain optimal performance and prevent premature electronic failure. Keep your body and head facing forward. Do not attempt to turn around or look backwards while the treadmill is running. Stop your workout immediately if you feel pain, faint, dizzy or are short of breath.


Caution — Risk of Injury

While you are preparing to use the treadmill, do not stand on the belt. Place your feet on the side rails before starting the treadmill. Start walking on the belt only after the belt has begun to move. Never start the treadmill at a fast running speed and attempt to jump on!


Using the Safety Key

Your treadmill will not start unless the safety key is placed in position. Attach the clip end securely to your clothing. This safety key is designed to cut the power to the treadmill if you should fall. Check the operation of the safety key every 2 weeks.


If the console reads SAFETY KEY OFF or only displays dashes, verify the following:

  • Verify the safety key is securely in place.
  • If using a magnetic key, make sure the key is magnetized.



Never use the treadmill without securing the safety key clip to your clothing.
Pull on the safety key clip first to make sure it will not come off your clothing.



Your treadmill is powered by a power supply. The power must be plugged into the power jack, which is located in the front of the machine near the stabilizer tube. Some treadmills have a power switch, located next to the power jack. Make sure it is in the on position. Unplug cord when not in use. NOTE: Some treadmills have an on/off switch located behind the console.



Never operate product if it has a damaged cord or plug, if it is not working properly, if it has been damaged, or immersed in water. Please reference contact information on the back cover of the INFORMATION CARD for assistance.


If the treadmill circuit breaker trips during a workout, verify the following:

  • Make sure the treadmill is plugged into a dedicated
    15-amp circuit.
  • Verify that you do not have the machine on an extension cord or surge protector.
  • Confirm that the machine is not plugged into a GFCI-equipped outlet or on a circuit that has a GFCI‑equipped outlet on it.
