DEF FILTER
DEF filter is an filter element to clean DEF sucked from the
DEF tank by DEF pump, and to supply it to DEF injector.
NOTICE
• The DEF filter element needs to be replaced every
2000 hours. For details of the replacement procedure,
see “METHOD FOR REPLACING DEF FILTER (4-78)”.
• If the machine is operated without DEF filter attached,
or with the filter other than Komatsu genuine parts,
foreign materials may enter into DEF pump and DEF
injector which will cause failure of the machine. Never
operate the machine without DEF filter attached, nor
use the filter other than Komatsu genuine parts.
• DEF filter cannot be flushed. Flushing or regenerating
of it will degrade the performance of DEF filter, and will
contaminate DEF pump and DEF injector which will
cause the failure of the machine. Never reuse the DEF
filter.
