MAINTENANCE AND SERVICING
Engine intake air is drawn through a duct (A) from the
cooling box that precleans the air and then through a dual
element
fi
lter (B).
The
air
cleaner
canister
is
equipped
with
an
aspirator (C) that removes dust continuously from the air
cleaner housing.
Figure 5.58: Air Intake System
The air cleaner is also equipped with a restriction switch (A)
that activates a warning display and tone on the cab display
module (CDM) when the
fi
lter system requires servicing.
After servicing the
fi
lter, the restriction switch must be reset
by pushing the button at the end of the switch.
IMPORTANT:
• Do
NOT
run engine with air cleaner disconnected or
disassembled.
• Over-servicing the
fi
lter element increases the risk
of dirt being ingested by the engine and severely
damaging the engine.
• Filter servicing should only be performed when
the CDM indicates “ENGINE AIR FILTER” or
at the speci
fi
ed interval.
