Problem Type: Equipment
Workspace: Woodshop
Asset: Drum Sander - Supermax 25/50
Summary: Vibration noises, belt track issues
Additional Info: I believe the v-belt needs to be replaced. The sandpaper stopped spinning and the belts got very hot, and they no longer hold tension very well, even after adjustment. The vibration noises are in cadence with oscillations seen in the v-belt rotation.

You mean the 36” wide belt sander? The 25-50 drum sander does not have “V” belts or sanding belts. If it is the wide belt sander, when you hear it squealing during operation you should quickly look at the ohmmeter in the upper left corner (white trinket with a needle) if the needle is over 25 you should use one of the emergency switches to prevent damage to the machine. The squealing is telling you the machine is overloaded. If is not stopped quickly, the drive belts will do the squealing as they slip on the drive pulleys and you will get a nice burnt rubber smell or even smoke. The belt will get super hot if it doesn’t trip the limiting switches. At times the belt will shredded to pieces. Lastly the limiting (tracking)switches could break. An over heated belt should never be used as is pretty much useless. Both the abrasive on the cloth and more importantly the glued joint of the belt have been compromised not to mention that the belt is stretched beyond the 60” tolerance. I suggest you identify the belt(s) involved and put them out of commission (tear them or dispose of them) so no one that is unaware try to use them. In the future when feeding the stock check the ohmmeter if it goes over 25, stop the machine. Use the manual wheel below the table to release your stock before restarting. You should never re-start the machine while the drum/belt is engaged to your stock.
