Air Intake System
IMPORTANT
Do not run engine with air cleaner
disconnected or disassembled.
Engine intake air (A) is drawn through a duct (B)
from the cooling box that pre-cleans the air, and
then through a dual element filter (C). The air
cleaner canister is equipped with a vacuator
valve (D) that removes dust continuously from
the air cleaner housing. The air cleaner is also
equipped with a restriction switch (E) which
activates a warning light on the CDM with an
alarm when the primary filter element requires
cleaning.
NOTE
The warning light could activate when
operating in extremely dirty conditions, in
which case the filter element should be
cleaned. Under normal operating
conditions, filter servicing should be
performed at the specified interval. Refer
to Section 7.15, Maintenance Schedule.
