Connecting the hydraulic circuits
To connect the attachment hydraulic lines,
observe the following procedures:
1. Release the pressure remaining in the
lines, and then close the stop valve.
Refer to “Releasing the residual pressure”
on page 2-66.
2. Remove the plugs.
3. Connect the attachment hydraulic lines to
ports (a/c) and (b/d). When installing a
hydraulic breaker, connect the supply
circuit to the port (a) and the return circuit
to port (b).

5. When connecting is complete, purge air
from the hydraulic lines.
a. Start the engine and run it at a low idle
speed with no load for 10 minutes.
b. With the engine running in 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 at least 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 applicable.
6. Check for oil leaks.
Disconnecting the hydraulic circuits
1. Release the pressure remaining in the
lines, and then close the stop valve.
