ELECTRONIC KEY LOCK OPERATION
MANUAL
Electronic key lock
The controller exclusively designed to read the data
stored in the IC chip built in the key judges whether or
not to start the engine and to operate the hydraulic sys-
tem. To the contrary that usual keys are identified by the
difference in groove pattern curved on the key, the IC
chip allows the key to identify using electrical signals,
patterns of which can be made in trillions, resulting in
copying the key is very difficult.
Electronic key lock system
The controller equipped in the cab reads the data stored
in the IC chip built in the key and checks electrically
whether the key used is a correct one or not to the cor-
responding machine serial No. The controller reads the
IC data when the key switch is turned ACC. When the
correct key is used, the engine is started in due course. If
an incorrect key is used, the engine will not start even if
the key is turned to the START position.
NOTE: If the start switch is turned ON two to three
times with an incorrect key, the horn will sound
to inform abnormality. Once the horn sounds, it
continues to sound for about 4 minutes even
though the key switch is turned OFF. Turn the
switch ON with the correct key to stop the horn
sounding.
