Dear Sir:

I hope you are very well, in union with your family.

Thank you by your request, and I will help you inmediately.

Please follow the next step with very carefully:

    • 1
Makesure that the surge protector being used is properly grounded(Very Important) and turned on.Check that the treadmill power cord is properly plugged into the surgeprotector.
    • 2
Checkto see that the key is inserted in the console.
    • 3
Checkthe circuit breaker on the frame near the power cord. If the reset/off circuitbreaker has tripped, wait 5 minutes and then reset the breaker by pressing theswitch in.
4)Check the circuit braker panel house, and reset.
Static Shock Problems:

Many people face a conundrum when using a treadmill. The problem is that a treadmill has you walk or run in a motion that causes you to build up an electrical charge on your body while you are exercising.
The problem if you are swinging your arms, you are totally isolated from any common ground so the charge just builds and builds and many discharges have been measured above 30,000 volts.

You may say, how in a frost-covered hell can I build up 30,000 volts on my body without killing myself? Good question and it has a good
answer...there is very little amperage. It will pop you good when you do ground and sting but it won't hurt you.
The problem is that it can damage the treadmill's electronics if it is not properly designed and we still see poor designs in this respect

If you don't like getting popped or if your treadmill is shutting down or going crazy, there is a fix. You can ground yourself to keep the electricity from building up on your body.

We now have wrist grounding straps that can be reused and attach to the frame of the treadmill without causing any markings and do not require any permanent modification to your treadmill. You can find them in any online catalog by electronic sales by searching for Grounding Strap.

Thank in advance, sincerely. God bless you.

Where can I find a Precor 9.21 treadmill motor cover?


Do you know which version of the Precor 9.21 you have? There are a few different versions you can view here. Click on your version to view the parts list and look for "Cover, Motor" or "Motor Cover".

For instance, if you have the 9.21 (AYYZ), the proper motor cover is this part #5019749

However, this part #5005569 is listed as the proper motor cover for the 9.21 (F5), 9.21i (2X), 9.21s (F6), 9.21si (2Y), and a couple others. Make sure you have matched up your exact model number with the motor cover you need so do you not order the wrong part.

My Precor 9.35 treadmill keeps shutting off. At first I thought this was due to use or it getting overheated. But, today I turned it on several times and it would shut off as I was walking on it. The...


Is it on an extension cord? Take it off any extension cords and make sure it's on a dedicated 120v circuit. No other items on the circuit. Also, how old is it? Precor made a bunch of the 9.3x series from 2002-2005 with an aluminum tail roller that can cause problems. Check the back roller. Is is silver and non-magnetic? if that's the case, you have an aluminum roller and you need to contact precor. If you're the original owner of the machine, they should warranty the replacement of the parts, if not, you'll have to buy at the very least a running belt and new roller.
