If they are loose, they may vibrate during operation and rub against other parts. There is danger that this may
lead to damage to the hoses and cause high-pressure oil to spurt out, leading to fire and serious personal injury.
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 after-
treatment devices 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)”.
