Proform 770 EKG treadmill (slipping and loud screech)

by Manage My Life Last activity date:
November 16th, 2010

I have a Proform 770 EKG treadmill. The model number is 831291661. Less than one minute of walking on the treadmill, I almost slipped. After applying pressure on the belt (from the feet), I almost fell twice. Accompanied with that is a screeching sound. With one foot on the side of the rail, I applied pressure with my other foot on the walking belt. The belt stops and screeches as long as the pressure is applied. Once I took that foot off the walking belt, the walking belt continues to run "normally". This slipping and screeching occurs when pressure is applied to the walking belt at low and high speeds.

Any help is appreciated.

Thank you for your question.

I am sorry you are having a problem with the treadmill. I suspect one of the belts is loose. I recommend unplugging the treadmill and remove the motor cover. Then plug the treadmill back in and carefully start the treadmill. When you put you foot on the walking belt watch the front roller area. If the roller continues to spin when the walking belt stops, you need to adjust the walking belt. I have provided you with the instructions for adjusting the walking belt below.

If the roller stops either the drive belt is loose or the roller pulley broke loose from the roller. If the pulley broke loose from the roller, you need to replace the roller. If it is just a loose belt, you can adjust the belt. To adjust the drive belt, loosen the bolts that mount the motor. By hand, pull the motor back so the belt is tight. Now have someone tighten the mounting bolt while you hold the motor. Now carefully walk on the treadmill and make sure the belt is not slipping. If the treadmill works fine, you can reinstall the motor cover. I hope this is helpful.

Please let me know if you need further assistance.
