When changing materials, flush the equipment
multiple times to ensure it is thoroughly clean.
•
Always clean the fluid inlet strainers after flushing.

Check with your material manufacturer for
chemical compatibility.

When changing between epoxies and urethanes or
polyureas, disassemble and clean all fluid
