Nilfisk GSD 700 Watt Motor-Head Now Obsolete. Previously Used in Older GS Machines
This fully serviceable motor, was for a long time, used in the Tellus and Nilfisk GS90 the GS80 the GS81 the GS8, and the Nilfisk GS83 and GM83 vacuum cleaners.
Partslist is HERE Service manual is HERE
I strongly advise if stripping the motor down, for a successful replacement of parts, a Nilfisk Jig should be used.
SAFETY WARNING! All electrical parts should ONLY be fitted by an electrically COMPETENT person.
You can take the opportunity in all models, except the Nilfisk GS83 to upgrade, to the more powerful, Nilfisk and Tellus GMP motor heads 12112153
However, where the application is for use with fine dust, it's suggested the 800 Watt Nilfisk and Tellus GSP motor head 12108153 is used.
The reason for suggesting the use of a less powerful motor, would be because it will reduce the chance of the filters and dustbag to clog up, preventing the flow of air through the filter, leading to possibly overheating the motor. The dust migrating through the filter into the motor would be reduced too.
For applications such as engraving, silk-screening, wood cutting etc, where a Nilfisk GSD (or GST or GSJ etc.) is integrated within a machine, they can be re-furbished here in Perth Western Australia as we have a supply of salvaged parts.
If you want any other replacement parts and accessories featured below, standard postage is capped at a maximum of $25 within Australia, and free postage after a $400 spend!
