PRECAUTIONS WHEN USING ROPS
•
If ROPS is installed, the ROPS must never be removed when operating the machine.
•
The ROPS is installed to protect the operator if the machine should roll over. If is designed not only to support
the load if the machine should roll over, but also to absorb the impact energy.
•
The Komatsu ROPS fulfills all of the regulations and standards for all countries, but if it is rebuilt without
authorization or is damaged when the machine rolls over, the strength will drop and it will not be able to fulfill its
function properly. It can only display its performance if it is repaired or modified in the specified way.
•
When modifying or repairing the ROPS, always contact your Komatsu distributor.
•
Even if the ROPS is installed, it cannot show its full effect if the operator does not fasten the seat belt properly.
Always fasten the seat belt when operating.
PRECAUTIONS FOR ATTACHMENTS
•
When installing and using an optional attachment, read the instruction manual for the attachment and the
information related to attachments in this manual.
•

attachments could create a safety problem and adversely affect the proper operation and useful life of the
machine.
•
Any injuries, accidents, and product failures resulting from the use of unauthorized attachments will not be the
responsibility of Komatsu.
