Electric Bosch hand held orbital sander belt not rotating properly

I was just about to do some sanding with a hand held orbital sander (bosch 150w) and it worked for a second, then the belt inside started turning really slowly and struggling and a bit of smoke came out as well. I turned it off and plug it in again and it did the same slow turning. Not sure what happened. Wonder if anyone knows i would be grateful!

My guess is that your sander got gunk in the belt and other rotating parts and you are either burning up the belt, or (hopefully not) the motor windings. Rick

Changing the rubber pad on the Bosch PEX 12 AE


I'm not familiar with that particular model, but they are virtually all replaced the same way. There are a few screws through the pad into the base. Simply remove them and screw the new pad on. You'll see that it's quite simple once you get the new pad in your hands.
Just be careful not to strip the head of the screw: use the right size screwdriver tip.

I hope this information allows you to resolve this issue. If you need further assistance, please post back with a comment to this thread. If I've managed to answer your question or solve a problem, please take a moment to kindly rate this post....thanks!

Orbital sander flicking the sand paper off


You did not specify how the sanding discs are meant to be attached to your sander's backing pad.  My experience with this type of problem is material from the sanding process builds up on the backing pad and does not allow the sanding discs to adhere properly.  If you have a velcro type system, clean the hooks on the sander's backing bad by soaking the pad's face in a plate of paint thinner for 20 to 30 minutes then use a wire brush to remove the rest of the paint physically.    For adhesive pads clean the sander's backing pad surface with denatured alcohol.  Do not use isopropryl or rubbing alcohol as this may not be 100% alcohol and could contain a lubricant like glycerin.  When the sander's backing pad is completely dry and clean it will hold adhesive backed pads fine.    Flaky paint is best scraped off before sanding, use a wide putty knife or a paint scaper to remove large flakes before sanding.  This will minimize airborne dust and cleanup.    For best results with adhesives, always keep your surfaces  clean!    Good luck and happy sanding!  Michael Mittelsdorf

Toothed belt bosch 1274 dvs


If I am correct, when holding the tool in the normal operating position there should be an oblong cover on teh left hand side nea the back of the tool. It should be held on with a screw. remove this cover and you can access the belt . MAKE SURE THE TOOL IS UNPLUGGED. the belt should pull off/push on with a bit of force. Turning the pulleys as you put it on will help it go on evenly. If it is too stiff, put the belt in some boiling water for a minute or two to soften it up a bit.

Orbital sander


You should really take it back to place of purchase and get it replaced/fixed under waranty. If you try anything other than checking the fuse you will invalidate the warranty. Most manufacturers allow retailers to replace faulty tools within seven days of purchase. Be sure to take your receipt with you as a copy will be needed for the shops warranty claim.

How many Types of Sanders?


Belt sanders: Belt sanders are useful for removing large quantities of wood stock quickly. They are generally used for rough sanding before fine finishing with a smaller sander. Palm sanders: Palm sanders are ultra-portable and useful for finishing small projects. Orbit sanders: Orbit sanders are usually more heavy-duty than palm sanders and appropriate for larger projects.
