We also recommend installing the VE service unit
(495886). The service unit filters and lubricates the
compressed air and enables an adjustment of the
air pressure. An IAS adapter (454757) is available to
connect Festool pneumatic tools to the IAS system.
The operating pressure of the tool must be 6 bar for
the automatic switch-on unit to function correctly.

Temperature cut-out
A temperature cut-out switches the mobile dust ex-

cool for about 5 minutes then switch on again.
Not possible to switch on: contact Festool ser-
