Q:

Howdy, I have a Proform 740 CS that the incline does not work. Can I get diagnostic help?

A:

I am sending you a wiring schematic that shows the voltages you should read at the test points. You will read a phantom voltage on the terminals sometimes when they are not getting voltage. You should read 120v on the up terminal when the up button is being pushed.

Q:

I am having problems with my Sears treadmill (Pro Form 740 CS). The 15 amp circuit breaker keeps popping out.

A:

I am sending you some suggestions of things to check. Before doing these tests you should measure the voltage to the treadmill. See what the voltage is with the treadmill off. Start the treadmill and get someone to walk or run on it and see if the voltage drops. You need 110-120 volts ac to the power supply board or the motor controller. If you are using an extension cord, measure the voltage with the extension cord and again with the treadmill plugged into the wall outlet. If the voltage is lower with the extension cord, the extension cord is not heavy enough.

Several things can cause the belt to slow down when you walk on it. The motor controller or the motor can cause this problem. To test the motor and controller someone needs to read the motor output at A+ and A- on the motor controller with the treadmill running. This will be between 10-80 VDC. Then let someone step on the belt and walk and see if the voltage increases to compensate for the load. Usually the voltage will increase 5-10 VDC. If the voltage increases the controller is doing its job and the motor is weak.

The most common cause of the belt slowing down is a dry or worn out belt and or board. Lift the edges of the belt and look at the walking board and feel of the belt and board. They should be smooth and slick. If the walking belt and board don't seem worn, you should lubricate the belt and board with part number 219168 belt lubricant. The procedure for lubricating the belt is:

Turn the belt by walking on it without the motor running until the belt seam is just past the front roller. Lift the belt and put 1/2 the tube onto the walking board in a zigzag pattern. Move the belt until the belt seam is just in front of the rear roller and put the rest of the lubricant on the walking board.

Start the treadmill and walk on all sections of the belt for 10 minutes. This should distribute the lubricant evenly.

Use only this special belt lubricant on the walking board and belt. Regular silicone spray or other lubricants might gum up the wax on the belt and you will have to replace it.

Q:

I got a part for my table saw from Sears. The part nos. match, but the bore in the part is .010 small. Short of a machine shop what can I do?

A:

I am afraid a machine shop is you best bet. The company that manufactured this saw for Sears has not manufactured a power tool for Sears for 10-12 years. We can't get parts easily for them and so I don't think reordering is an option.

We don't have the size of the hole in the arbor support. The hole should be a tight fit for the arbor shaft but it is not pressed on.
