You can try and blowing it out with compressed air but I dont think that I would try any lubrication, however if you decide to I would use WD-40

Sheets keep coming off during sanding


The sandpaper will come off for one of these reasons: 1. The spring clips are to loose to hold the sandpaper. 2. You are using sandpaper that the paper's either too thick for the clips to hold it or too thin to withstand the work you are putting it through. 3. (Most likely) You are pushing down on the sander too hard while sanding. These types of sanders work by their own weight with only a little help from you.

Bosch ROS not powering on


Checked the net for answers and got a couple of maybe's. 1.) Brushes, 2.) variable speed control, which some were direct wiring.
I tried the brushes firs and that has solved the problem for now. I guess the brushes stuck or somehow lost contact.
I got a parts diagram and found the brushes (will be covered with dust). Took the springs out and stretched them a little, replaced and the sander turned on. You will need to remove the top cover to do this. Verdit is still out as to long term performance. Not a great start.

My particular sander was lightly used (second project) and it has not been abused.

Unit will not power on. Tried different circuits. Has had time to cool, but should not have been hot. Tool has had limited light use. Has not been dropped.


check the board with the variable speed control knob, mine failed once and would not power on. I believe I started having the same problem for the second time today.

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.

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.
