GENERAL PRECAUTIONS COMMON TO OPERATION AND MAINTE-
NANCE
•
Check the wiring every day for looseness or damage. Reconnect any loose connectors or refasten wiring
clamps. Repair or replace any damaged wiring.
Fire caused from piping
Check that all the hose and tube clamps, guards, and cushions are securely fixed in position.
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 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) (3-124)".
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 (3-115)".
PRECAUTIONS WHEN GETTING ON OR OFF MACHINE
USE HANDRAILS AND STEPS WHEN GETTING ON OR OFF MACHINE
To prevent personal injury caused by slipping or falling off the machine, always observe the following.
•
Use the handrails and steps marked by arrows in the fig-
ure When getting on and off the machine.
•
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, tighten any loose bolt of the handrails and steps.
If the handrails and steps are damaged or deformed, they need to be repaired immediately. Ask your Ko-
matsu distributor to perform this work.
•
Do not grip the control levers when getting on or off the machine.
•
Never climb on the engine hood or covers where there are no non-slip pads.
•
Do not try to get on a tire from the step in the rear side of the machine or the step beside the cab.
