PROTECTION AGAINST FALLING, FLYING OR INTRUDING OBJECTS
On jobsite where there is a danger of falling objects, scattering
fragments, and things which may intrude into operator's cab, in-
stall the necessary equipment to protect the operator depend-
ing on the working conditions.
• When operating on jobsite, such as mines or quarries
where there is a hazard of falling rocks, install falling object
protective structure (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 op-
erator in the surrounding area where there is a danger of
falling objects, scattering fragments.
• When performing demolition or breaker operations, install
a front guard and always keep all the windows closed dur-
ing operation. In addition, always check that there is no
one except the operator in the surrounding area where
there is a danger of falling objects, scattering fragments.
Above precautions are developed for the standard jobsite. De-
pending on the conditions of the jobsite, installation of addition-
al guards is necessary.
Do not operate the machine without the necessary guards. Be
sure to consult with your Komatsu distributor about necessary
guards.
