Question about Proform Crosstrainer 755 Console Treadmill
No, officially you are not supposed to lube it. But it's recommended that you regularly do that, they even provide you with a lube kit. Try this first, it may be as simple as that.
It can't be a problem with the belt, if it would have been one you would have noticed it at high speeds, not low ones. Your problems are caused by the fact that the control unit is no longer capable of controlling the engine finely. This can be caused by 3 main causes:
1 - the engine itself (its bearings to be more precise) is faulty. You can just do a basic test:disconnect it from the band and spin it by hand - if you feel or hear grinding then the engine is dead and must be replaced by them.
2 - the control module is fried - the only way you can test it is to measure the voltage to the motor with it in operation. This is something that is best to be left to them.
3 - the speed sensors on the engine are no longer function correctly: either the sensors are full of dirt and gunk and need to be cleaned or the sensors (or the connecting cables) are defective - the only thing you can do is to clean them thoroughly and make sure all cables are firmly plugged in.
If this hasn't helped then it's time to call
