Servisignal™ Mini Indicator; Exhaust System; Engine Mounting - Peterbilt 348 2017 Operator's Manual

ServiSignal™ Mini Indicator
The ServiSignal™ Mini Indicator is
installed on the air cleaner or air
induction piping so it has access to
clean filtered air. As the filter plugs
and restriction increases, a red flag
appears in the window. When it
reaches the red zone, the air filter
should be replaced. The indicator can
be reset by pressing the button at the
end of the indicator.
