CONTROLS
Auxiliary Hydraulic Lines
WARNING
Oil may spurt out if 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.
These lines deliver the hydraulic oil
necessary for operating a hydraulic breaker,
crusher or other attachments.
Stop valve ...... : Closed : Open
Connecting the Hydraulic Circuits
To connect the attachment hydraulic lines,
use the following procedures:
1. Move the auxiliary pedal several times to
relieve pressure on the lines.
2. Make sure the stop valves are closed.
3. Remove the plugs.
4. Connect the attachment hydraulic lines
to ports (a) and (b).
When fitted with a hydraulic breaker,
connect the return circuit to port (b) and
the supply circuit to port (a).
5. Open the stop valves.
When fitted with a hydraulic breaker,
open the selector valve (1).
6. When connecting is complete, purge air
from the hydraulic lines.
Accessories
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 pedal 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.
7. Check for leaks.
Before dismantling the attachment, move
the auxiliary pedal several times to relieve
pressure on the lines and be sure to close
the stop valves.
Selector valve
