• 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 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  use  a
fully  transparent  laminated  coating  sheet  on  the  front
glass. Keep all the windows and doors closed when oper-
ating. In addition, always check that there is no one except
the operator in the surrounding area where there is a dan-
ger of falling objects, scattering fragments.

• When performing breaker operations, install a front guard

and use a fully transparent laminated coating sheet on the
front glass. Keep all the windows closed when operating .
In  addition,  always  check  that  there  is  no  one  except  the
operator  in  the  surrounding  area  where  there  is  a  danger
of 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.

ACTIONS IN THE EVENT OF DAMAGE TO SAFETY STRUCTURES

The following components comprise the machine safety structure that can prevent injury to the operator from
falling objects, flying objects and intruding objects as detailed in the previous section.

• Operator cabin
• FOPS (falling object protective structure)
• Front window guard

In the event any of the above parts become broken or damaged such that their function would be impaired, they
must be replaced with genuine Komatsu replacement parts.
No attempt should be made to repair these parts as this may have an adverse effect on component strength or
durability.
If such a repair is undertaken without authorisation from Komatsu there is a danger that a problem might occur
that will lead to serious personal injury.
If in doubt please contact your Komatsu distributor.
Komatsu can not take any responsibility for accidents, failures or damage caused by unauthorised repair to the
above mentioned components.
