Turbine Maintenance
General Instructions
The turbine unit should be cleaned and checked
routinely. Maintain your turbine unit as you would care
for any of your professional tools. The following steps
should be taken to protect both yourself and the unit
before proceeding.
1) Turn off the turbine unit and allow it to cool down
before attempting to service it.
2) Unplug the turbine unit before attempting any service to it.
Daily
Clean any material that may have accumulated on the
turbine and wipe any materials from the hoses. Remove
and clean the foam pre-filter by blowing it out with air or
shaking it.
NOTE: Relief vent at the rear of the turbine must be kept
clear at all times.

Remove the two screws and the two washers that hold
the filter cover and the external air filter, (the 240 has 2).
Remove and inspect the pleated paper filter by holding it
up to a light. If you cannot see light through it, it must be
replaced. The Series 22 filters are not held in place by a
filter cover. The filters can be removed by hand.
Keeping the turbine filters clean is extremely important.
Dirty or clogged filters will dramatically reduce the life
and performance of the turbine unit. Order PN 92-469
turbine filter package for the Series 22, PN 92-254 for
the Series 23, PN 92-255 for the Series 230 and PN 92-
301 for the Series 240.
NOTE: A turbine motor will run trouble free for an extended
period of time. Eventually, however, the carbon brushes will
wear and need to be replaced. It is recommended that the
unit be taken to a service center for evaluation. Refer to the
troubleshooting chart (see page 9).
