PRECAUTIONS FOR HIGH-TEMPERATURE COOLANT
To prevent burns from boiling water or steam spurting out when
checking or draining the coolant, wait for the coolant to cool
down to a temperature where the radiator cap can be touched
by hand. Then loosen the cap slowly to release the pressure in-
side the radiator, and remove the cap.
PRECAUTIONS FOR HIGH-TEMPERATURE OIL
To prevent burns from hot oil spurting out or from touching
high-temperature parts when checking or draining the oil, wait
for the oil to cool down to a temperature where the cap or plug
can be touched by hand. Then, loosen the cap or plug slowly to
release the internal pressure and remove the cap or plug.
PRECAUTIONS FOR HIGH-TEMPERATURE PARTS
To prevent burns from touching high-temperature parts, when checking or performing maintenance after stop-
ping engine, check the parts have been cooled down to touch with bare hand before checking or maintenance.
PRECAUTIONS FOR HIGH-PRESSURE OIL
The hydraulic system is always under internal pressure. In addition, the fuel piping is also under internal pres-
sure when the engine is running and immediately after the engine is stopped. When performing inspection or
replacement of the piping or hoses, check that the internal pressure in the circuit has been released. If this is not
done, serious personal injury or death may occur. Always observe the following.
• Do not perform inspection or replacement work with the circuit under pressure.
Release the pressure. For details, see “STOP ENGINE BEFORE CARRYING OUT INSPECTION AND
MAINTENANCE (2-33)”.
• If there is any leakage from the piping or hoses, the surrounding area may be wet, so check for cracks in
the piping and hoses and for swelling in the hoses.
When performing inspection, wear protective equipment such as protective eyeglasses and leather gloves.
• High-pressure oil leaking from small holes is dangerous
that may penetrate your skin and cause loss of sight if it
contacts your skin or eyes directly. If a jet of high-pressure
oil hit your skin or eyes, and suffer injury, wash the place
with clean water, and consult a doctor immediately for
medical attention.
• The oil pressure in the ECSS circuit is stored by the accu-
mulator. Do not remove the ECSS piping and parts.
If it is necessary to remove them, ask your Komatsu dis-
tributor to perform the removal work.
PRECAUTIONS FOR HIGH-PRESSURE FUEL
While the engine is running, high-pressure is generated in the engine fuel piping. If you try to disassemble the
piping before the internal pressure is released, serious personal injury or death can result. When performing
