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; () After assembly, exposed holes should be treated for dust prevention; () Apply rust inhibitor on the input shaft and flange; (4) When painting, the nameplate and installation surface need to be covered to avoid painting. Precautions for operation (1) When transporting hydraulic pumps, do not subject the drive shaft of the pump body to strong impact. (2) Before operation, it is necessary to exhaust through the exhaust port and 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 reach 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.
