7.8.5 AIR INTAKE SYSTEM
IMPORTANT
Do not run engine with air cleaner
disconnected or disassembled.
Engine intake air (A) is drawn through a duct (B)

vacuator valve (D) that removes dust continuously
from the air cleaner housing.

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
