GENERAL PRECAUTIONS COMMON TO OPERATION AND MAINTE-
NANCE
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) (3-143)".
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 (3-133)".
