Can anyone provide a manual or directions on how to change the belt on this Sander. I just received it from my Wife's grandfather and it doesn't have any instructions.

The front roller pushes straight back toward the drive roller and locks such that you can apply new/different grit. After applying a new belt (make sure arrow inside belt aims in direction that the belt turns - for directional belts) pushing the front roller again unlocks it and applies the correct pressure for proper sanding. There is a knurled knob, about 5/8 to 3/4" in dia. inside the belt center which is used to center the belt WHILE IT IS RUNNING. You can put the sander on it's back, on the work bench, to center the belt on the metal friction ptate between the belt and the sander body.New parts are avail at this URL: belts

I found myself in the exact position you describe, having acquired a virtually unused belt sander model 315-11750 and a number of 'new' belts.

I followed the instructions left by your respondent, but my sander would not readily unlock after I had locked it. I found that the best method for locking the assembly into install position was to place the front roller vertically on the edge of my workbench and push down on the entire tool. This method, however, did not unlock the rollers to complete the installation.

I suspected the mechanism had grown tight and dry through lack of use over the years.

Finally I unscrewed the centering knob completely and squirted WD-40 into the orifice. This helped a little, but I found the device continued to be sticky and hard to operate for belt changing.

I had a number of 'new' belts, but the adhesive at the join had deteriorated so badly that several of them split right away. I finally put the sander away.

I found that if the knurled adjustment knob is tightened, you get the behavior you described (front roller can be pushed back, but won't release). I found that if I loosened the knurled adjustment knob, the front roller doesn't get stuck. In fact, it seems like the adjustment knob serves to lock the front roller in the pushed back position. That is, to change the belt, I loosen the knurled knob, push back the front roller, then tighten the knurled knob to lock it in place. I slip off the old belt, slip on the new, then while pushing back again on the front roller, I unscrew the knurled adjustment knob so that the roller will release back into the normal operating position. I push the front roller using the method described above (pushing down on the whole unit while in the vertical position, front roller down, at the edge of a bench). The same knurled knob centers the belt. You center the belt by running the unit upside down (a little at a time at first) and adjusting the knurled knob until the belt is centered and stable. I picked mine up at a garage sale (old auto mechanic who died). Seems like a really hefty industrial strength beast, but I haven't put it through its paces yet.

Funny that I came here through a search on a way to work the belt adjustment in order to remove and install a belt. I took me a good hour to figure out how to get slack via the front roller when removing a belt. For this, hold the unit as you would while working. Point the nose to the floor and apply pressure. The roller retracts and stays in place. Then, to re-extend the front roller; you lay the unit on the floor (belt down/handle up). Roll the unit to the right 45 degrees, tilt the unit forward until the roller contacts the floor. Apply slight downward pressure (unit still tilted forward at at the same angle) and the front roller pops back into place. That part took quite a bit longer to figure..
