Installation Notes:

• Using genuine GRACO parts ensures compatibility, reliability, and optimal performance of the lubrication system.
• Ensure proper alignment and secure connection of inlet and outlet fittings
• Verify that the injector is compatible with the system’s grease type and pressure requirements
• Regularly inspect the visual indicator pin for proper operation and cycle confirmation
• Follow manufacturer’s guidelines for maintenance intervals and seal replacement
• Use only compatible grease (up to NLGI #2)
• Maintain system pressure within specified limits (1200–3500 psi)
• Periodically check for leaks and wear on seals and fittings
• Replace injectors as part of scheduled maintenance to prevent system failure
