CONTROLS
Releasing residual pressure
After the auxiliary hydraulic circuits have
been used, pressure remains in the circuits.
This is called the residual pressure. Release
this residual pressure before disconnecting
the lines.
1. Start the engine and lower the safety bar
to the released position.
2. Press the auxiliary hydraulic switch (B).
(The residual pressure is released from the
(a) port line, and pressure is generated in
the (b) port line.)
3. Press the selector switch (C) until the
built-in lamp lights up to select the one-
way flow
(The residual pressure is released from the
(b) port line.)
4. Turn the key to the OFF position.
Operating the auxiliary hydraulic circuits
The auxiliary hydraulic circuits are used for
running various attachments (working
equipment) such as the breaker and angle
bucket. The control of these circuits is
performed by operating the auxiliary
hydraulic buttons or the slider switch.
1. Select the direction of the hydraulic oil flow
by operating the flow selector switch (C).
(One-way flow or two- way flow)
Refer to “Flow selector switch” on page
2-27.
ACCESSORIES
2. Select the operation mode for the auxiliary
hydraulic button (A) by operating the
detent mode switch (D).
Refer to “Detent mode switch” on page
2-27.
IMPORTANT: Do not operate the machine
in the detent mode for a long time. Doing
so will increase the hydraulic oil
temperature and shorten the service life
of the hydraulic units.
3. Operate the auxiliary hydraulic buttons
and slider switch as follows.
Auxiliary hydraulic buttons
To discharge from the hydraulic oil port (a)
....................................................Press (A)
To discharge from the hydraulic oil port (b)
................................................... Press (B)
Auxiliary hydraulic slider switch
To discharge from the hydraulic oil port (a)
................................................Move to (A)
To discharge from the hydraulic oil port (b)
................................................Move to (B)
If the flow direction has been set to “One-
way”, the auxiliary hydraulic button (B) and
the (B) side of the slider switch cannot be
used; the port (b) is reserved for the return oil
circuit in the one-way mode.
