Controls
Selector valve (Option)
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)
on the machine body.
Second auxiliary hydraulic switch
Slider switch
(Proportional control)
Proportional control allows for slow-to-fast/
fast-to-slow movement of attachment.
Example: If you move the slider switch half
way, the attachment will move at
approximately one-half the speed.
acceSSorieS
Move this switch to control the flow of the oil
in the second auxiliary hydraulic lines.
(C): .... Hydraulic oil flows to the left auxiliary line (c).
(D): .... Hydraulic oil flows to the right auxiliary line (d).
Releasing the residual pressure
Refer to “Accumulator” on page 2-46.
Third auxiliary hydraulic switch and
button
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.
