Fire around the machine due to highly heated exhaust gas
This machine is equipped with Komatsu Diesel Particulate Filter (hereafter KDPF).
KDPF is a device to purify the soot in the exhaust gas. Exhaust gas temperature may increase during the purifi-
cation process (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 job site, set the system to the regener-
ation disable to prevent fire hazards due to highly heated exhaust gas during the aftertreatment devices regen-
eration. For setting, see “HANDLE Komatsu Diesel Particulate Filter (KDPF) (3-121)”.
If the following materials are loaded to the machine equipped with the dump body heating specification, fire may
occur because the dump body becomes highly heated during the aftertreatment devices regeneration.
• Objects which contains many combustible industrial wastes
• Objects which mainly contains combustible materials such as dry leaves, chips, pieces of paper, and coal
dusts
Take appropriate actions to prevent fire.
For details of remedies, see “DUMP BODY HEATING SPECIFICATIONS (3-237)”.
Explosion caused by lighting equipment
• When checking fuel, oil, battery electrolyte, or coolant, always use lighting with anti-explosion specifica-
tions.
• When taking the electrical power for the lighting equipment from the machine, see “POWER SUPPLY OUT-
LET (3-109)”.
