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 hydraulic
attachment.

Connecting the Hydraulic Circuits
To connect the attachment hydraulic lines,
use the following procedures:
1. Release the pressure remaining in the
lines then close the stop valve.
When equipped with accumulator.
Refer to “Releasing the residual pressure”.
2. Remove the plugs.
3. Connect the attachment hydraulic lines to
ports (c) and (d).
4. Open the stop valves.
5. 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.
6. Check for leaks.
Operating
Move this switch to control the flow of the oil
in the second auxiliary hydraulic lines.
(C) .... Hydraulic oil flows to left auxiliary
line(c)
(D) .... Hydraulic oil flows to right auxiliary
line(d)
Disconnecting the hydraulic circuits
1. Release the pressure remaining in the
lines then close the stop valve.
When equipped with accumulator.
Refer to “Releasing the residual pressure”.
2. Disconnect the lines from ports (c) and (d).
