DO NOT GET CAUGHT IN WORK EQUIPMENT
The clearance in the area around the work equipment changes according to the movement of the link. If you are
caught, this may lead to serious personal injury or death. Do not allow anyone near any of the rotating or
telescopic parts.
PRECAUTIONS RELATED TO PROTECTIVE STRUCTURES
The operator's compartment is equipped with a structure (such as ROPS, OPG) to protect the operator by ab-
sorbing the impact energy.
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.
PROTECTION AGAINST FALLING, FLYING OR INTRUDING OBJECTS
On jobsites where there is a hazard that falling objects, flying
objects, or intruding objects may hit or enter the operator's cab,
consider the operating conditions and install the necessary
guards to protect the operator.
• When working in mines or quarries where there is a haz-
ard of falling rock, install FOPS and a front guard, and use
a laminated coating sheet on the front glass (internal side).
When carrying out the above operations, always close the
front window. Always check that there is no one except the
operator in the surrounding area. They may be hit by fall-
ing objects or flying objects.
• When carrying out breaker operations, use a fully transpar-
ent laminated coating sheet on the front glass (internal
side). Keep all the windows closed when operating and al-
ways check that there is no one except the operator in the
surrounding area. They may be hit by flying objects.
The above recommendations assume that the conditions are
for standard operations, but it may be necessary to add addi-
tional guards according to the operating conditions on the job-
site. Always contact your Komatsu distributor for advice.
In such a case, do not operate the machine without an addi-
tional guard. Be sure to consult with your Komatsu distributor about necessary guards.
