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)”.
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 (3-110)”.
PRECAUTIONS WHEN GETTING ON OR OFF MACHINE
USE HANDRAILS AND STEPS WHEN GETTING ON OR OFF MACHINE

• Use the handrails and steps marked by arrows in the fig-
ure on the right when getting on and off the machine.

Please call your Komatsu distributor and ask for repair or
replacement of the step.
• Always face the machine and maintain at least three-point
contact (both feet and one hand, or both hands and one
foot) with the handrails and steps to ensure that you sup-
port yourself.
• Before getting on and off the machine, check the handrails
and steps if there is any oil, grease, or mud on them. Wipe
it off immediately not to slip if any. In addition, repair any
damage and tighten any loose bolt.
• Do not grip the control levers or lock lever when getting on
or off the machine.
• Never climb on the engine hood or covers where there are
no non-slip pads.
