CONTROLS
AUXILIARY HYDRAULIC LINES
(OPTIONAL)
WARNING
Oil may spurt out if the caps or filters are
removed or pipes disconnected before
releasing the pressure in the hydraulic
system.
• When removing plugs or disconnecting
hoses, release the internal pressure
before removing.
• When disconnecting hoses, stand to the
side and loosen them slowly to
gradually release the internal pressure
before removing.
These lines deliver the hydraulic oil necessary
for operating a hydraulic breaker, crusher or
other attachments.
ACCESSORIES
Flow rate ............ 70 L/min (18.4 US gpm)
Rated Pressure ... 20.6 MPa (2987 psi)
Connecting the hydraulic circuits
To connect the attachment hydraulic lines,
observe the following procedures:
1. Release the pressure remaining in the
lines.
Refer to “Releasing residual pressure” on
page 2-37.
2. Remove the plugs.
3. Connect the attachment hydraulic lines to
the ports (a), (b) and (T).
When a hydraulic breaker is installed:
a. Connect the supply circuit to the port (a)
and the return circuit to the port (b).
b. Press the selector switch until the built-
in lamp lights up to select the one-way
flow.
· The port (T) is used for the drain
circuit (when necessary).
4. 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 buttons
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.
5. Check for oil leaks.
Disconnecting the hydraulic circuits
1. Release the pressure remaining in the
lines.
Refer to “Releasing residual pressure” on
page 2-37.
2. Disconnect the lines from the ports (a) and
(b).
3. Install the plugs.
