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 the work in the site such as a mine or a
quarry where rocks may fall on, have falling object protec-
tive structure (FOPS) and the front guard installed, and
have the front glass laminated. 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.
• When operating the demolition work or the breaker opera-
tion, have the front guard installed, and have the front
glass laminated. 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.
