PRECAUTIONS RELATED TO ATTACHMENTS AND OPTIONS

Any injuries, accidents, product failures or other property damages resulting from the use of unauthorized

When installing optional parts or attachments, there may be problems with safety or legal restrictions. Therefore
contact your Komatsu distributor for advice.
Depending on type of combination of work equipment, there is hazard that the work equipment may hit the cab
or other parts of the machine. During operation, an interference of the work equipment with the machine may
cause a serious personal injury. Before using unfamiliar work equipment, check there is hazard of interference,
and operate within not contact.
When installing and using optional attachments, 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 operations 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 it is scratched, replace it with the new part as soon as possible. If the window is scratched and
is not replaced, there is 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 machine
must be operated inside a building or under ground, where the
ventilation is poor, take steps to ensure that the engine exhaust
gas is removed and that ample fresh air is brought in.
