Assembly precautions (1) During the assembly process, please be careful not to leave burrs on the assembly surface and do not allow dust to enter; (2) After assembly, apply dust-proof treatment to the exposed holes; (3) Apply rust inhibitor to the input shaft and flange; (4) When spraying paint, the nameplate and installation surface need to be covered to avoid painting. -Operation precautions (1) When transporting hydraulic pumps, do not apply strong impact to the drive shaft of the pump body; (2) Before operation, it is necessary to exhaust through the exhaust port to fill the housing with clean hydraulic oil; (3) When running the hydraulic pump, be careful not to let hydraulic oil and other liquids flow onto the surface of the hydraulic pump assembly; (4) The cleanliness of the hydraulic oil used should meet NAS level 9.

Application Scenarios:
1. Harvesting Operations – Hydraulic pumps power critical components like the header, feed rollers, and stalk choppers, ensuring
efficient corn picking and processing.

2. Driving Systems – Used in hydrostatic transmissions for smooth speed control and maneuverability in varying field conditions.

3. Grain Handling – Supports hydraulic augers and elevators for seamless grain transfer to storage or transport vehicles.

4. Adjustable Mechanisms – Enables real-time adjustments of header height, reel speed, and other parameters for optimal harvest
quality.

5. Steering & Braking – Integrates with hydraulic steering systems for precise control, especially in large, modern harvesters.
