Dear Sir,
We recommend you check brushes and springs and replace if necessary. Also clean out slots of commutator. You might also have to smooth same by hand turning between extra fine (800-1200) Emery or Crocus cloth, also remove all extra dust …
Best regards,

Where can I purchase carbon brushes? Do you sell parts?
How do you get a hold of some new carbon brushes for my E Series Vacuum cleaner?
I would like to know how to install a new cord on a vacuum cleaner. It is a rainbow. where are the screws? Should I tie a knot in the cord before putting it in the machine? Is there a place to buy a new cord like the old one? …etc.
Where can I get the therminal fuse link for the rainbow canister suction motor “E” series. Mine was locked up due to cleaning or lack of and opened up the high temp link wired into the motor core. This is a one time protection fuse link. is soldered in series with the motor field. tks mw
