• 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.
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 in-
spection or maintenance of the fuel piping system, stop the engine and wait for at least 30 seconds to allow the
internal pressure to go down before starting the work.
HANDLE HIGH-PRESSURE HOSES AND PIPING
If oil or fuel leaks from high-pressure hoses or piping, it may cause fire or defective operation. It is dangerous
and may cause serious personal injury or death. If the hose or piping mounts are loose or oil or fuel is found to
be leaking from the mount, stop operations and tighten to the specified torque.
If any damaged or deformed hoses or piping are found, consult your Komatsu distributor.
Replace the hose if any of the following problems are found.
• Damaged hose or deformed hydraulic fitting.
• Frayed or cut covering or exposed reinforcement wire layer.
• Covering swollen in places.
• Twisted or crushed movable portion.
• Foreign material embedded in covering.
PRECAUTIONS FOR HIGH VOLTAGE
When the engine is running and immediately after it is stopped,
high voltage is generated inside the engine controller and the
engine injector, and there is danger of electric shock. Never
touch the inside of the engine controller or the injector part of
the engine. If it is necessary to touch the inside of the engine
controller or the injector part of the engine, consult your Komat-
su distributor.
PRECAUTIONS FOR NOISE
When performing maintenance of the engine and you are exposed to noise for long periods of time, wear ear
covers or ear plugs while working.
If the noise is too loud, it may cause temporary or permanent hearing problems.
