CONTROLS
Selector valve
Open ....... When using a hydraulic breaker
(1-way flow)
Closed ..... When using a reversible
attachment (2-way flow)
Change the direction of the hydraulic oil flow
by opening or closing the selector valve (1)
inside the fuel lid.
Use the high-flow only in the 2-way flow. If it
is used in the one-way flow, the brake may
overheat.
Third auxiliary hydraulic switch and
button
acceSSorieS
The third auxiliary hydraulic lines are normally
used to control the “quick attachment”
installed to connect/disconnect the bucket.
When the safety lock lever is released after
the engine is started, hydraulic oil flows into
the pipe (e). This allows the pressure in the
(e) side to increase and to prevent the pin
inserted on the bucket from coming out. If
the pressure in the (e) side drops, the alert
that the bucket may come out is indicated by
the warning lamp and the alarm. For a safety
reason, the bucket can be disconnected only
when the button (1) and the switch (2) are
pressed at the same time. When they are
pressed, the hydraulic oil flows into the line (f)
to increase the pressure there. As the result,
the pin on the bucket comes out and the
bucket is removed from the machine.
Third auxiliary hydraulic warning lamp
This lamp illuminates and an alarm sounds
when the third auxiliary hydraulic pressure
drops abnormally, when the safety lock lever
is fully lowered to the unlocked position while
the engine is running.
