6. GENERAL PRECAUTIONS SAFETY 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 lower. When modify- ing it, consult your Komatsu distributor. If ROPS is deformed by falling objects or by rolling over, its strength lowers and its design functions cannot be main- tained.
In this case, be sure to ask your Komatsu distribu- tor 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, There- fore 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.
When installing and using optional attachments, read the instruction manual for the attachment, and the gen- eral information related to attachments in this manual. CAB WINDOW GLASSES If the cab glass on the work equipment side is broken, there is a hazard that the work equipment may contact the operator's body directly. Stop operation immediately and replace the glass. UNAUTHORIZED MODIFICATION Any modification mode without authorization from Komatsu can create hazards. Before making a modification, consult your Komatsu distributor. Komatsu will not be responsible for any injuries, accidents, or product failures resulting from modifications made without authorization from Komatsu. 2-8
