NOTICE
• If the engine is operated without the filter element, the turbocharger and aftercooler become dirty
and their performance will lower and that can cause engine problems such as overrun caused by
suction of oil. Therefore, do not start the engine without the filter element.
• The filter element cannot be cleaned. Flushing or regenerating of the filter element will degrade per-
formance of the filter. As a result, the turbocharger and aftercooler become dirty and the perform-
ance lowers or the crankcase pressure increases. Never reuse the filter element since it can cause
an engine failure.
• After the filter element is replaced, if KCCV is not assembled correctly, oil or blowby gas may leak.
Replace the filter element in the correct procedure.
