SAFETY
GENERAL PRECAUTIONS COMMON TO OPERATION AND MAINTENANCE
2-17
q
If the protective structure is welded, or holes are drilled in
it, or it is modified in any other way, its strength may drop.
Consult your Komatsu distributor before carrying out any
modifications.
q
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 contact your Komatsu dis-
tributor for advice on the method of repair.
q
Even if the protective structure is installed, always fasten your seat belt properly when operating the machine.
If you do not fasten your seatbelt properly, it cannot display its effect.
PROTECTION AGAINST FALLING, FLYING, INTRUDING OBJECTS 2
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.
q
When operating on jobsites, such as mines or quarries,
where there is a hazard of falling rocks, install FOPS and a
front guard, and always keep all the windows and doors
closed when operating. In addition, always check that
there is no one except the operator in the surrounding
area. They may be hit by falling objects or flying objects.
q
When carrying out demolition or breaker operations, install
a front guard and always keep all the windows closed
when operating. In addition, always check that there is no
one except the operator in the surrounding area. They may
be hit by falling objects or flying objects.
q
If, furthermore, the machine is used for standard opera-
tions, it is also necessary to install additional guards,
depending on the prevailing conditions at the jobsite.
In such a case, do not operate the machine without an
additional guard. Be sure to consult with your Komatsu dis-
tributor about necessary guards.
