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).
5. Open the stop valves.
6. 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 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
