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
How do I remove the backing pad on the Bosch PDA
Piece of cake. Just push the red slider as far as it will go in the direction of the arrow. Look for the seam where the pad attaches to the sander plate, that is where it separates. Give the rubber a little tug, and it should come off quite easily. Pop the new pad on, lock it in place by pushing the slider button as far as it will go (in the opposite direction to the arrow) and job's a good 'un!
Going slow,then stopped
You may want to try blowing compressed air through the ventilation slots on either side of the motor to remove any built up dust particles . You may also consider replacing brushes .
Sandpaper will not stick to rubber bed bosch
This is generaly due to previous adhesive buildup on the backing pad OR, the face of the backing pad is breaking down and cracking.There are two ways to handle this. You can try scrubing the crud off the pad (I wouldn't) or, you can get a new backing pad for your sander. At this point, you might want to go with a velcro type pad or hook and loop as they call it (cleaner and no goop). Check your local home depot for pads. If you cannot find one, I would suggest you call Klingspor abrasives Co. They have area reps all over the United States. I know, as I used to be one of them.They carry,.. and will send you pads via UPS. Just make sure you don't try to put a 6in pad on a 5in sander or vice-versa as the pads are weight-mated to the sanders. If you do, you will burn up the motor in your sander rather quickly.
I can't get the sandpaper to stay on the pad.
It sounds like you need to replace the backing pad on the sander. Over time the velcro (hook & Loop) on the backing pad will loose its stick. A Bosch service cneter can supply you with a new one, just let them know which model you have. If its an adhesive back sanding pad the same thing applys just get a new one. Hope this helps
CLEANING SANDER BUSHINGS
It's usually not the brushes but the commutator that needs cleaned. The commutator is the surface the brushes ride on. Go to Walgreens and buy a multi-surface nail file, one of the soft ones that are about 3/4" square with different colors for different grits. Don't start at the coarse grit!! Start at the medium grit and lightly drag it over each section in a smooth arcing motion, when the commutator surface is shiny it's clean, then replace the brushes with new ones.

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

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.
