ServiSignal™ Mini Indicator
The ServiSignal™ Mini Indicator is
installed on the air cleaner or air
induction piping so it has access to
clean ltered air. As the lter plugs
and restriction increases, a red ag
appears in the window. When it
reaches the red zone, the air lter
should be replaced. The indicator can
be reset by pressing the button at the
end of the indicator.
Exhaust System
The exhaust system is part of the
noise and emission control system.
Periodically check the exhaust for
wear, exhaust leaks, and loose or
missing parts.
For details see Noise
and Emission
Control on page 5-116.
Please refer
to the Engine Operator's
Manual for more details on how to
maintain the emission's components in
the exhaust system.
