Applications:
Medium pressure, low to medium volume grease dispensing in industrial, mining, agricultural, and vehicle service environments.

Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance.
• Always use GRACO-designed suction tubes with a built-in relief device for wall mount applications.
• Install an inlet screen to prevent debris from entering the pump and plugging relief passages.
• Periodically inspect the inlet screen for plugging, especially when changing the container.
• Ensure proper air supply (20–150 psi recommended for operation).
• Follow manufacturer guidelines for hose and accessory installation.
• Regularly inspect and clean inlet screens.
• Check for oil leakage through air exhausts and replace throat seal (u-cup) if necessary.
• Clear any clogs in fluid lines, hoses, or valves as needed.
