Third Auxiliary Hydraulic Switch
and Button
Press those switch and button to control the
flow of the oil in the third auxiliary hydraulic
lines.
When the safety lock lever is released after
the engine is started, hydraulic oil constantly
flows in pipe (e). When button (1) and switch
(2) are pressed simultaneously, the oil flow
switches to pipe (f). When this happens, the
pressure of pipe (e) drops, an alarm is
sounded and the warning lamp lights. For
safety, only operates when both button (1)
and switch (2) are pressed.
Disconnecting the hydraulic circuits
1. Release the pressure remaining in the
lines.
Refer to “Releasing the residual pressure”.
2. Disconnect the lines from ports (e) and
(f).
3. Install the plugs.
Releasing the residual pressure
After using the auxilliary hydraulic circuits,
pressure remains in the circuits. This is called
the residual pressure. Release this residual
pressure before disconnecting the lines.
1. Stop the engine.
(The residual pressure is released from
the (e) port line.)
