Komatsu H75051, Operation & Maintenance Manual

Page: 43 / 440

As for the machine equipped with ROPS, if the machine weight
(mass) exceeds the certified value (shown on ROLL-OVER
PROTECTIVE STRUCTURE (ROPS) CERTIFICATION plate),
ROPS will not be able to fulfill its function. Do not increase ma-
chine weight beyond the certified value by modifying the ma-
chine or by installing attachments to the machine.
Also, if the function of the protective equipment is impeded, the
protective equipment will not be able to protect the operator,
and the operator may suffer injury. Always observe the follow-
ing.
• If the machine is equipped with a protective structure, do
not remove the protective structure and perform operations without it.
• If the protective structure is welded, or holes are drilled in it, or it is modified in any other way, its strength
may drop. Any modification is prohibited.
• If the protective structure is damaged or deformed by falling objects or by rolling over, its strength will be
reduced and it will not be able to fulfill its function properly. In such cases, always consult your Komatsu
distributor.
• Even if the protective structure is installed, always fasten your seat belt properly when operating the ma-
chine. If you do not fasten your seatbelt properly, it cannot display its effect.
Always fasten your seat belt while operating the machine.

PRECAUTIONS WHEN RUNNING ENGINE INSIDE BUILDING
The engine exhaust gas contains substances that may damage
your health or even cause death. Start or operate the engine in
a place where there is good ventilation. If the engine or ma-
chine must be operated inside a building or underground,
where the ventilation is poor, take steps to ensure that the en-
gine exhaust gas is removed and that ample fresh air is
brought in.
