Concave Air Removal

This procedure calibrates Active Concave Isolation Air Removal by removing air from the hydraulic system of ACI. Perform this calibration if the hydraulic system has been opened to atmosphere for service or repair. Failure to complete this calibration results in less than optimal performance.

Before entering concave air removal calibration, verify that leveling cap screws are in storage position, air removal hoses are installed, and the engine is running. See your Operator's Manual for further information.

Perform Calibration When:

• Hydraulic components for the concave system have been serviced or replaced.
• Air has entered the hydraulic system.
