Always run at regulated 80 psi; verify at the tool with an in-line regulator.
Wear eye/ear protection and gloves; secure workpieces before sanding.
Add a drop of air tool oil to the inlet before each session; use filtered/dry air.
Start the tool on the surface to avoid disc edge scuffing; keep pad flat.
Inspect pads and discs regularly; replace if worn, cracked, or unbalanced.
