Third Auxiliary Hydraulics
WARNING
Oil may spurt out if caps or filters are
removed or pipes disconnected before
releasing the pressure in the hydraulic
system.

When disconnecting hoses, release the
internal pressure before removing.
These lines deliver the hydraulic oil
necessary for operating a quick attachment.
Connecting the Hydraulic Circuits
To connect the attachment hydraulic lines,
use the following procedures:
1. Release the pressure remaining in the
lines .
Refer to “Releasing the residual pressure”.
2. Remove the plugs.
3. Connect the attachment hydraulic lines to
ports (e) and (f).
4. When connecting is complete, purge air
from the hydraulic lines.
a. Start and run the engine at low idle with
no load for 10 minutes.
b. With the engine running at low idle
operate the auxiliary hydraulic switches
repeatedly (approx. 10 times) to purge
air from the hydraulic lines.
c. Stop the engine and wait for more than
5 minutes until bubbles escape from the
hydraulic oil in the tank.
IMPORTANT: Follow the procedures for
purging air as instructed by the
attachment manufacturer if specified to
do so.
5. Check for leaks.
Operating
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 (3) 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.)
