KDPF is a device to purify the soot in the exhaust gas. Exhaust gas temperature may increase during after-
treatment regeneration. Do not bring any combustible material close to the outlet of the exhaust pipe.
When there are thatched houses, dry leaves or pieces of paper near the work site, set the system to disable the
regeneration before starting the work to prevent fire hazards due to highly heated exhaust gas during KDPF re-
generation. For the setting procedure, see “HANDLE Komatsu Diesel Particulate Filter (KDPF) (3-115)”.
