REGULAR CHECKS AND MAINTENANCE WORK
C Cleaning with compressed air
Pressure of compressed air must be under 205 kPa (2.1
kgf/
), and the element should be blown clean from the
inside to the outside until the dust deposits are noticeably
reduced.
A If the air suction is still inadequate, or the color of the
exhaust gases is abnormal even after the cleaning, the
air cleaner element must be replaced.
A Clean the air cleaner element regularly or foreign
particles will accumulate, which will cause the DPF to
become clogged in a shorter amount of time than
expected. If this happens, the normal cleaning interval
for the DPF (3000 hours) can't be followed.
A Do not tap-clean the element. The element may get
deformed, which may adversely affect the air cleaner
performance.
BCleaning Evacuator Valve
To avoid personal injury or death:
A Wear eye protection.
A While cleaning, foreign matters may drop out of
the evacuator valve.
1. Open the rear door and engine hood.
2. Remove the dust-cover.
3. From behind the dust-cover, remove foreign matters of
the evacuator valve.
(1) Evacuator valve
(2) Dust cover
A Failure to clean the evacuator valve may get the air
cleaner element's service life shorter.
(A) Clean from behind
