maintenance of the minibeadbeater 16

The Mini/beadbeater-16 does not have a brush motor.  Instead, it has a massive induction motor that requires no brushes nor any other kind of maintance.

If you encounter a problem with your MBB-16, contact the Manufacturer.  They will gladly help you: http://www.biospec.com/support/

im sorry i'm speeking about a minibeadbeater-8.

The MBB-8 is no longer being manufactured. It's replacement is the MBB-16 selling at a price that is only slightly higher than what a new MBB-8 sold for. It's a superior machine in many aspects.

Like the MBB-16 and MBB-24, the two piece, clam shell stainless steel case of the MBB-8 is held together with eight aluminum rivets. These can be drilled out with a 1/8" drill bit, four on the top, four on the bottom.

Inside the MBB you will find a modified Milwaukee brand Reciprocating Sawzall. New brushes can be ordered from the original manufacturer but it is not possible to change out the entire Sawzall with a new, "off the shelf" one because BioSpec made essential modifications to the Milwaukee machine in order to incorporate it into the MBB-8.

If you choose to change out the brushes, let us know if you need 8 replacement pop-rivets. We'll send them gratis.
