Why does my buffer make a black mark on the floor

I apologize, but I need more information about the specific model of the Eclipse propane floor buffer to locate the manual and provide troubleshooting steps. Can you please provide the model number or any additional details about the buffer?

The rectifier is in the top end of the motor. Take the cover off and then the top end plate of the motor. With the bolts removed, you will have to tap and rock the plate to evenly remove it. Carefully look at the marks on the old and new part to be shur you do not make a mistake in the wiring. A drawing and photo might be nice too.

Wax remover. Rewax spot after removing wax.

The owner's manuals for the Electrolux (now Aerus) B-8, B-9 (Floor Pro and similar models), and the TriStar ProStar shampooer (same machine as the Floor Pro) have just been uploaded.
