Question about Bosch 3107DVS Electric Sanders & Polishers

1 Answer

Bosch 3107 dvs sander stopped working. At first it seemed like it was shorting out, and by turning the speed adjustment sometimes it started working again. Eventually it completely stopped. Took it to a tool shop and got it back in pieces because I did not want to pay $150 to get it repaired. Any help?

    OK, but how do you do that

  • Thomas F. Schneider May 11, 2010

    You most likely have an intermitant open in the speed contriol. You can isolate and test it with an ohm meter. If I am correct,obtain and replace the control.

Craftsman 315.117150. The belt keeps sliding off, as soon as turned on and start to sand. It seems to be on correctly.


You need to adjust the tracking knob which is by the front handle that looks like a triangle head screw. Make sure the belt tension leaver is tight and the belt has enough tension on it. Quickly press and release the start switch and note the centering of the belt. It should be in the center of the bottom platen. If it is not, adjust the tracking knob and bump the switch again. If the belt is going in the wrong direction turn the knob the other direction. Once you are close the center of the platen, press the power switch to turn the unit on and lock the trigger. Firmly hold the unit vertically from the front handle. Fine adjust the tension knob to center the belt and make sure the belt is not hitting the case which will cause damage. You should be able to use the belt sander without the belt slipping off. Let the sander do the work, do not push down and limit the side to side motion. If the belt will not stay on then the belt is too large or the torsion spring needs to be adjusted to applying more tension on the belt and drive roller.

My Bosch 1276 DVS belt sander abruptly stopped working. Could it be the switch?


that is possible, but was the tool operating properly first?? unplug tool and check the cord for any breaks, then what I would do is clean the tool as good as possible with compressed air and if you can remove the brush caps do so and check the condition of the spring and clean the area. DO NOT sand the brushes but look across the face to see if both look worn evenly. If you have a volt ohms meter check from the plug to the brush holder with the switch on brushes removed to see if you have continuity and if not then I would have to think the switch

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.

Bosch 3283 dvs sander has unbalanced spin


This means the sander has been droped and the pad support and/or the bearing orbit has been bent, maybe even the motor shaft. Never leave any power tool sitting on a bench, always set it on the floor, it will end up there at some time anyways. You can try replacing a part at a time and spend a lot of money and time, but is it worth it?

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.
