OPERATION
REMARK
• Do not use 2 or more ID keys overlapped each other. The
machine may not be able to start the engine since it may
not be able to recognize the ID correctly. (In this case, the
"ID Key Not Registered" screen is displayed on the ma-
chine monitor.)
When using a ID key, keep it apart from the other ID keys.
• You cannot start the engine with a key having no built-in IC
chip, registration key (gray), or usual key (black) which is
not registered in the machine.
• If the ID key system has any abnormality, the "ID Key Sys-
tem Abnormality" screen is displayed. If this screen is dis-
played, call your Komatsu distributor.
