Any time the parking brake is disassembled or lines removed, the system will require bleeding.
To bleed the system proceed as follows:
REMEMBER: As the brake switch must be depressed several times while bleeding, this job has to be done with two persons.
1 Park the combine on level ground and block the wheels adequately to prevent the combine form rolling.
2 Raise the header and engage the header safety latch. Stop the engine.
3 Remove the rubber cap (2) from the bleed screw (1).
4 Slide a transparent hose over the bleed screw to catch the oil when bleeding.
5 Start the combine engine.
6 Disengage and engage the parking brake a few times.
7 At the same time open the bleed screw until air free oil escapes through the bleed screw.
8 Engage the parking brake and stop the engine.
9 Remove the transparent hose and reinstall the rubber cap, (2).
10 Check the proper hydraulic reservoir for proper oil level.
