OK the belt tensioning mechanism is spring loaded. First what is the quality of the belts are they real flimsy or stiff. You say the rollers spin but my question does the rear roller still spin and the belt remain stationary. If so the rubber belt on motor is bad. I would take a look for excessive wear on the rear roller. Does the yoke mechanism snap forward or move slowly, look for a build up of sawdust in this area that might be restricting movement on the yoke. The wear plate in still good condition. One other thing on the belts are they directional? Do they have an arrow on the inside if so that has to point toward front of tool. I looked at a breakdown and could not see anything else to suggest. I never had this problem except with belts when I was at Makita.

check the wear plate on the bottom and also check the front roller for being out of round is where I would start. Let me know if doesnt help

A makita power planer is just what it says, a planer. It has blades that spin at high speed and remove a thin layer of wood with each pass. The orbital sanding sheets go on another tool called an orbital sander. Write back if you find the sander and can not figure out how the sheets go on it.

I would say you have a bearing going out ether on the motor this web address will take you to a good break down of the housing I would say you need a motor bearing it will also give you a parts # but if you have a bearing supplier somewhere ( I look in yellow pages for electrical motor repair) you might find the bearing for a cheaper price just remember to take the old one with you so you are sure to get the same size. I have found bearing and belts for my table saws are the same as for some clothes washers for about 1/2 the price as ordering from sears
