Usage, installation, and care

Designed for straightforward installation, this pump arrives with components ready to assemble for most airless spraying machines. A small but important care tip: shake the pump several times before installation to prevent internal steel balls from sticking to the alloy plate, which can cause malfunction. Following this step helps ensure smooth operation from the start.

• All necessary parts are included for quick installation.
• Shake before install to reduce risk of internal ball sticking and potential issues.

Notes on safety and best practices

Use the pump with coatings within the stated pressure range and follow manufacturer guidelines for nozzle, tip sizes, and cleanup. The emphasis is on consistent performance and reliable operation, rather than promising guaranteed results in every environment. By selecting the right coatings and maintaining the unit, you can support a steady workflow and a clean finish.
