Install the CO₂ cartridge following the marker’s quick-pierce instructions; check seals and fittings for leaks before use.

Clean the barrel and cylinder after each session with the recommended cleaning tools to remove paint residue and prevent blockages.

For repairs or internal servicing, contact authorized service centers—do not attempt unauthorized internal modifications.
