Livestrong LS 8.0 walking belt slipping

Hi everyone!

New member here. Bought a Livestrong LS8.0 treadmill a couple weeks ago. It needed lubrication (even said so on the dash) so I did, using 100% silicone, as many have suggested. Now, when I would run on it prior to lubing, it would squeak, and the squeaking would come from the motor. So I also put a little bit of lube on the drive belt and the inner ring of the pulley (on the front roller). Belt started really slipping immediately as I got on after that.

Since then I learned that maybe I should not have lubed the drive belt. So I cleaned it, multiple times, very thoroughly with rubbing alcohol and de-greaser, so I think at this point it should be fine. The drive belt is also quite tight and does not look damaged at all. And the belt is slipping less, but it still is slipping. It's more of a wobble than a full slip, but it happens everytime I step on it.

It works perfectly on higher inclines. Running up the hill feels as good as ever. But the minute I bring the incline down to flat, it starts wobbling again.

So looks like the belt started wobbling after lubrication. I have since cleaned the deck and lubed the belt multiple times, but still no avail.

What could be wrong with it? I find it strange that something happened to the walking belt after I lubed it, but maybe something did.

Any help is appreciated. Thank you!


  • Hello and good morning!

    You might just need to adjust the tension! Check out these videos for direction!
  • Hello :)

    Thank you for your response. Oh yeah, I tried adjust the tension, centering it more, but it still is slipping. I never overtightened it, but somehow I dont think that would fix the problem.
  • What is your serial number?
    Here are a few things you can look into to see why your running belt is stopping when you walk on treadmill.
    • Let’s remove the hood cover on your treadmill.
    • Now run the treadmill at 2.5mph with no one on it and see how it runs.
    • Now go ahead and step onto the belt and see what happens.
    1st Few things to look at when you’re running belt stops.
    A) When the running belt stops does the Drive Motor also stop?
    B) If yes then it could be a weak Drive Motor or bad Motor Controller.
    2nd When the running belt stops does the Drive Motor continue to run and also does the drive belt continue to run?
    A) If the Drive motor still runs and Drive Belt does not then you will need to tighten down the Drive Belt or replace the Drive Belt.
    3rd When the running belt stops and Drive Motor & Drive Belt continues to spin does the entire front roller rotate?
    A) If the entire front roller continues to spin then you will need to adjusted running belt.
    B) If just the pulley on the front roller continues to spin, then you will need to replace the entire front roller.
    This should help you trouble shoot exactly what is wrong with your treadmill, and remember to lube your Running Belt & Deck every 6 months.
