Belt is slipping and squeaking when walked upon what type of lubricant should be used

Squeaking is normally caused by a bad bearing or a slipping drum belt.

the only lubrication that needs done is between the walking belt and the deck. if a roller is squeaking either front or rear you can try using wd40 on the bearings on either side

Hi Paula, I know nothing about it, you could lift the belt and use DW40 or vegi spray where it's squeaking. Nothing beats a walk in the park. Greg.

HI,

Its time to lubricate your treadmill.
You must obtain the proper lubricant for your treadmill. There are several different types. Contact your manufacturer for what type is needed. Using the manufacturer provided allen wrench, loosen the walking belt approximately 10 full turns on each side of the rear roller. Apply approximately 1/2 ounce of lubricant directly in the middle of the walk area underneath the walking belt upon the deck. Retighten the rear roller 10 turns on each side. Run the treadmill at 6.0 mph for 2-3 minutes to spread the lubricant evenly. Wipe excess lube from the sides of the belt. Walk on treadmill to check for proper tension on belt.
for make it easy for you I have added a video. ok

Make sure you adjust vthe motor belt first, it may be where the slipping is coming from. You should only be able to twist a properly tightened motor belt 45 degrees. After that, readjust the walk belt. If you have been tightening the walk belt trying to get the slipping out it may be too tight now. Use the instructions in your owners manual to adjust the walk belt. Also, lube under walk belt with the recommended lubrication . That will help the walk belt not too grab and take pressue off of both belts. Good luck

* take nail polish or paint and place a mark starting on the front roller pulley and going onto the front roller metal shaft
* then try to walk on it and see if the white mark separates
* if it does then the roller is bad and would need replaced or tap screws placed through the pulley into the metal shaft to hold it in place
* if it doesn't separate then the drive belt is slipping and most likely will need replaced, although you could try spraying belt dressing on it to see if that would be a temporary fix.
* if neither of these is your problem and the walk belt is slipping then you will need to try to adjust the screws in the back of the treadmill through the end caps. these are allen wrench screws.
Tighten each one the same amount such as 1 full turn to start with.
see if you can now walk without it slipping.
If not then tighten 1-2 more turn on both sides.
If after 2-3 full turns it is not tight enough
I would recommend replacing the walk belt.

Hopefully this helps with your problem!

If the walking belt slips when walked on, first remove the key and UNPLUG THE POWER CORD. Using the hex key, turn both rear roller bolts clockwise, 1/4 of a turn. When the walking belt is correctly tightened, you should be able to lift each edge of the walking belt 2 to 3 inches above the walking platform. Be careful to keep the walking belt centered. Then, plug in the power cord, insert the key, and carefully walk on the treadmill for a few minutes. Repeat until the walking belt is properly tightened. Now if this does not solve this problem then check the drive belt and adjust accordingly, also reverse the process of the above mentioned

Check both belts to be sure they are adjusted and not slipping.Check the underside of the walk belt to see if it feels frayed in the center as compared to the edges, the center always wears more than the edges a really worn belt must be replaced. if it is nor worn there is a wax lubricant for proform treadmills that can be purchased at retail stores that sell treadmills.Sears, dicks sporting goods and also treadmilldoctor.com are good places to buy it.

Depending if this is a new issue or old, It could be a couple of issues. Check the belts for slipping. Proper tension on walking belt (check your manual) or drive belt -remove the cover and you might be able to see if the belt is slipping or it could be a load issue (electronics not sensing added load fast enough). My bet is belt tension. Also Lubricate,lubricate,lubricate
