Maintenance Tips

• Clean immediately after use: Flush gun body, nozzle, and air passages with water before mortar or fireproofing material hardens.
• Disassemble nozzle regularly: Remove and rinse the spray tip to prevent clogging and maintain even material flow.
• Inspect air valve & regulator: Ensure smooth adjustment and no air leaks for consistent spray pressure control.
• Check cam-lock connection (35mm): Keep coupling clean and tight to avoid pressure loss or accidental disconnection.
• Maintain seals & gaskets: Replace worn O-rings to prevent leakage and uneven spraying performance.
• Avoid dry material buildup: Never leave mixed mortar inside the gun—this is the main cause of blockages and wear.
• Light lubrication only where specified: Keep trigger mechanism smooth without contaminating airflow or material path.
• Store clean & dry: Keep in a dry case or toolbox to prevent corrosion and extend service life.
