UNAUTHORIZED MODIFICATION

• Komatsu will not be responsible for any personal injuries, product failures, physical loss or damage, or influ-

ence on the environment resulting from modifications made without authorization from Komatsu.

• Any modification made without authorization from Komatsu can create hazards. Before making a modifica-

tion, consult your Komatsu distributor.

PRECAUTIONS RELATED TO ATTACHMENTS AND OPTIONS

• Any personal injuries, product failures, physical loss or damage, or influence on the environment resulting

from the use of unauthorized attachments or parts will not be the responsibility of Komatsu.

• When installing optional parts or attachments, contact your Komatsu distributor for advice to any potential

problems or safety and legal requirements.

• The machine weight will not exceed ROPS certified value as long as the optional attachments written in the

attachment  combination  table  of  this  manual  are  installed.  When  installing  optional  parts  or  attachments
which  are  not  written  in  this  manual,  the  machine  weight  must  not  exceed  ROPS  certified  value.  Always
contact your Komatsu distributor before installing.

• Installing  some  work  equipment  combinations  may  cause  interference  and  damage  with  the  cab  or  other

parts of the machine during operation and could cause serious personal injury or death. Before using unfa-
miliar work equipment, always check for potential interference while operating the machine. Always ensure
the operator's safety when working with unfamiliar work equipment.

• When installing and using optional attachments, always read the instruction manual for the attachment, and

the general information related to attachments in this manual.

PRECAUTIONS RELATED TO CAB GLASS

• If the cab glass is broken during operations, stop operations and repair the cab glass immediately.
• If the cab glass on the work equipment side is broken, there is a hazard that the operator may be directly hit

or caught in the work equipment. If the glass is broken, stop operation immediately and replace the glass.

• The ceiling window is made of plastic, so if it is scratched, the visibility will become poor and there is danger

that it may break. If the ceiling window is scratched, replace it with the new one as soon as possible. If the
ceiling window is scratched and is not replaced, there is a danger that any rocks falling on it will cause it to
break, leading to injury to the operator.

PRECAUTIONS WHEN RUNNING ENGINE INSIDE BUILDING

The engine exhaust gas contains substances that may damage
your health or even cause death. Start or operate the engine in
a  place  where  there  is  good  ventilation.  If  the  engine  or  ma-
chine  must  be  operated  inside  a  building  or  underground,
where the ventilation is poor, take steps to ensure that the en-
gine  exhaust  gas  is  removed  and  that  ample  fresh  air  is
brought in.
