k
k
WARNING
Immediately after the engine is stopped, the parts are still very hot. Do not replace the filter immediately.
Wait until all of parts cool down before starting the work.
NOTICE
• Komatsu recommends using Komatsu genuine parts for replacement parts.
• 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 Komat-
su genuine parts.
• DEF filter cannot be flushed. Flushing or regenerating of it will degrade the performance of filter,
and will cause the breakage of equipment. Never reuse the filter.
• Improper assembly of DEF filter may cause leakage of DEF. Replace the DEF filter in the correct pro-
cedure.
After the engine is stopped, DEF system devices automatically purge DEF in DEF injector and DEF pump and
return it to DEF tank to prevent malfunction of the devices caused by freezing of DEF or deposition of urea.
After the engine is stopped, the devices are operated for a few minutes. Before replacing the filter, clean around
the DEF pump first after DEF system devices stop.

move equalizing element (2).
