• Hold a valid cartridge tool operator certificate before using any cartridge tool.
• Inspect the tool, barrel, and safety mechanisms before each use as per the manual.
• Select the correct cartridge colour and fixing length for the substrate material.
• Press the tool firmly against the surface at 90 degrees before firing.
• Wear hearing protection, eye protection, and safety boots during all operations.
• Check behind and around the fixing point for people, voids, and services.
• Store cartridges and tools in separate locked containers when not in use.
• Follow the misfire procedure exactly — wait 30 seconds before clearing.
• Keep unused cartridges in the original strip — never loose in pockets.
• Return defective tools to the supplier — never attempt your own repairs.

• DON'T use a cartridge tool without a valid operator training certificate.
• DON'T fire into brittle materials like glass, tile, cast iron, or thin steel.
• DON'T point the tool at anyone, loaded or unloaded, at any time.
• DON'T look into the barrel to investigate a misfire or blockage.
• DON'T fire fixings closer than 50mm to an edge — the substrate may shatter.
• DON'T use a stronger cartridge than the substrate and fixing require.
• DON'T carry a loaded cartridge tool between work positions on site.
• DON'T store tools and cartridges together in the same container overnight.
• DON'T fire through a wall without confirming nobody is on the other side.
• DON'T leave cartridge tools unattended or accessible to untrained persons.
