CAUTION
Clean the air cleaner element at the specified
interval. Failure to follow this instruction will
result in premature accumulation of PM in the
DPF and eventually cause the systems to mal-
function. On the contrary, unnecessarily fre-
quent cleaning can damage the air cleaner
element, allowing dust and other foreign matter
to be drawn into the engine.
NOTE:
Even if the cleaning interval has not elapsed, clean
or replace the element if clogging of the element
causes a decrease in engine output.
• Checking the air cleaner element condition
with dust indicator
Check the dust indicator once a week. If the
indicator’s window shows a red signal, the air
cleaner element is clogged. Clean the element
immediately.
WARNING
When cleaning air cleaner element, wear gog-
gles and a mask to protect your eyes and res-
piratory organs from dust.
And, use a dust collector to prevent dust
from dispersing into the surroundings.
