ACCESSORIES
Third auxiliary hydraulic warning lamp
This lamp illuminates and an alarm sounds if
the auxiliary 3rd hydraulic pressure drops
abnormally while the engine is running.
For the machine with the hard lock feature,
the lamp lights up and an alarm is sounded
only when the third auxiliary hard-lock switch
is turned on.

IMPORT
ANT: For handling of the
attachment, follow the instructions
provided in the attachment manual.
The third auxiliary hard-lock switch should be
installed in the third auxiliary if the attachment
to be installed on the piping of the third
auxiliary is capable of hard locking.
When operating the third auxiliary, this switch
is used.
The third auxiliary is mainly used to control
the “quick attachment” that connects/
disconnects the bucket.
After the engine is started, hydraulic oil flows
into the pipe (e) if the switch is off. This
allows the pressure in the (e) side to
increase, preventing the pin inserted into the
bucket from coming off.
When the switch is turned on by pressing the
switch (1) while pulling the orange portion (2),
the warning lamp starts flashing. The
hydraulic oil flows into the line (f) to increase
the pressure there. As a result, the pin on the
bucket comes off and the bucket is removed
from the machine.
