GENERAL PRECAUTIONS

PRECAUTIONS WHEN USING ROPS (Roll Over Protective Structure)

Install ROPS when working in places where there is danger of
falling rocks, such as in mines and quarries, or in places where
there is danger of rolling over.
If ROPS is installed, do not remove it when operating the
machine.
ROPS is installed to protect the operator when machine rolls
over. When machine rolls over, ROPS supports its weight and
absorbs its impact energy.
If ROPS is modified, its strength may be reduced. When
modifying, consult your Komatsu distributor.
If ROPS is deformed by falling objects or by rolling over, its
strength lowers and its design functions cannot be maintained.
In this case, be sure to ask your Komatsu distributor about repair
method.
Even when the ROPS is installed, if you do not fasten your seat belt
securely, it cannot protect you properly. Always fasten your seat
belt when operating the machine.

PRECAUTIONS FOR ATTACHMENTS

When installing optional parts or attachments, there may be problems with safety or legal restrictions. Therefore
contact your Komatsu distributor for advice.
Any injuries, accidents, or product failures resulting from the use of unauthorized attachments or parts will not be
the responsibility of Komatsu.
Always read the instruction manual for the attachment.

UNAUTHORIZED MODIFICATION

Any modification made without authorization from Komatsu can create hazards. Before making a modification,
consult your Komatsu distributor.
Komatsu will not be responsible for any injuries, accidents, product failures or other property damages resulting
from modifications made without authorization from Komatsu.

SAFETY AT WORKSITE

Before starting operations, thoroughly check the area for any unusual conditions that could be dangerous.
Check the terrain and condition of the ground at the worksite, and determine the safest method of operation. Do
not carry out operations at places where there is a hazard of landslides or falling rocks.
Take necessary measures to prevent any unauthorized person from entering the operating area.
When traveling or operating in shallow water or on soft ground, check the shape and condition of the bedrock, and
the depth and speed of flow of the water before starting operations.
Always design and maintain the roads on the jobsite so that the machines can travel safely.
