The fist thing I will have you try is to check for belt lubrication and ease of movement. Incline the walking platform all the way up. Then stand at the front of the walking area and give yourself a slight shove. You should slide back at least 75% of the way. If you do not, you will need to lubricate the belt. You can go HERE and order 219168 or 219170.

If you do slide back with no problems then we can assume the lube is fine and there is something else going on. I would suspect the controller and/or the motor. We can test the motor if you have a volt meter. If it looks like we need to test it, let me know back here on this thread and I will walk you through that procedure.

Thank you for using Manage My Life!

I checked for ease of movement as you recommended and I didn't slide back at all. I'll have to get some lubricant (219168) and retest to see if I'm able to slide back. I checked the owners manual and it recommends that the belt be 3 to 4 inches off the walking platform. My treadmill was only about 2 inches. I tried adjusting the height to 3 inches and the belt was very lose when walked on. So I ended up re-tightening the belt again. Do you know why I'm not able to adust the belt heigth as recommended in the owners manual without having the belt get so lose?

A:

The manual is correct about 3-4 inches. It is possible that because the lubricant has all worn off that it's going to not feel or act right as it is. Once you lubricate the belt adjust it to about 3 inches of lift and see how it acts. If you get the belt to where it feels right and moves as it should and still have the shutting down problem, let me know. You will need a volt meter to check the motor (dc volts) . but I can certainly walk you through how to check it.

Thank you for your recommendations! I'll start with lubricating the belt, then test if I slide back and finally check the height adjustment of the belt.

The part number for the belt lubrication kit is 219168. You can buy it at [ Sears parts direct | [ Sears Parts Direct. The cost is around $4.00. The application instructions should be in the package, but in case they are not here is how to apply the lubrication. Turn the walking belt until the belt seam is along the top of the front roller. Raise the belt on one side in the center of the walking board front to back as high as you can. Apply 1/2 the tube of lubrication to the walking board in a zig zag fashion moving from front to back. Move the belt until the seam comes up on top of the rear roller, lift the belt again, and put the rest of the lubrication on the walking board in the same manner. Turn the treadmill on and walk on the belt for 10-20 minutes. Walk all over the belt to distribute the lubrication evenly on the walking belt and board.
I hope this is helpful. Please let me know if you need further assistance. Mark

Thank you for your question.

I am sorry you are having a problem with the treadmill. By what you have stated I suspect the treadmill motor is working to hard and over heating. When the motor over heats it can, cause the overload in the motor to open or it could trip the breaker. The most common cause for this is a dry walking belt. When the belt is dry, it causes the motor to work harder. To test the walking belt lubrication, do not turn the treadmill motor on. Set the elevation to the highest level. Stand near the front of the walking belt. Push yourself firmly toward the rear of the treadmill. If the belt is properly lubricated the belt will take you to the rear edge of the treadmill to the floor. If you move and stop, the belt needs lubricating. The part number for the belt lubrication kit is 219168. You can buy it at [ Sears parts direct | Sears Parts Direct . The cost is around $4.00. The application instructions should be in the package, but in case they are not here is how to apply the lubrication. Turn the walking belt until the belt seam is along the top of the front roller. Raise the belt on one side in the center of the walking board front to back as high as you can. Apply 1/2 the tube of lubrication to the walking board in a zig zag fashion moving from front to back. Move the belt until the seam comes up on top of the rear roller, lift the belt again, and put the rest of the lubrication on the walking board in the same manner. Turn the treadmill on and walk on the belt for 10-20 minutes. Walk all over the belt to distribute the lubrication evenly on the walking belt and board.

If the belt seems to be fine, the problem could be a motor control or a motor. Both of these parts can be expensive to replace. To be sure, I recommend having a service technician come out and diagnose the problem. you can have it repaired at your home by a Sears technician.

Please let me know if you need further assistance on the treadmill.

Thank you for your question.

If the treadmill belt still slips after adjusting the walking belt the problem is most likely a loose drive belt. The drive belt is located between the motor and the front roller. To adjust the drive belt first, unplug the treadmill and remove the motor cover. Next, locate and loosen the motor mounting bolts. Then move the motor so that the belt is tight and have someone retighten the mounting bolts. It will take quite a bit of force to hold the belt tight. After the belt is tight plug the treadmill in and carefully test the operation. If the belt still slips, watch the front roller. If the roller stops but the pulley does not the roller is defective. If the roller and the pulley stop, the drive belt is still loose.

If the walking belt is too tight, the motor will over heat and cause the hot smell. I have provided you with an image below showing how to correctly adjust the walking belt.

Please let me know if you have any other questions.

Thanks Mark T. QUESTION Re: "...watching the front roller." I thought I explained that this slipping was intermittent. You can walk for up to several minutes and then a quick slip, then normal for another several minutes. How am I going to watch and actually SEE this roller stop/pause for a split-second? I've worked on cars for years and can usually tell if a belt is loose or worn. This belt is TIGHT, and appears new (It is the original, 2001), with the inner ribs sharp (no signs of wear).

If the belt is not slipping all the time, you can step a little harder on the belt while watching the roller. I hope this makes sense. I always checked the belt tension this way to ensure the belt is tight enough. Please be sure to use caution when doing this. If you do not feel confident doing this please have a technician come out and repair it for you.
