1. Inspect the Tool: Check for any visible damage or loose parts. Do not use a damaged tool.
2. Select Fasteners and Cartridges: Choose the appropriate Hilti fasteners (up to 72mm) and powder cartridges for your application (concrete or steel). Refer to Hilti's fastener selection guide for optimal performance.
3. Load Cartridge: Follow the specific instructions in the detailed manual for loading the powder cartridge into the tool's chamber. Ensure it is seated correctly.
4. Load Fastener: Insert the chosen fastener into the barrel of the tool.

Operating Instructions

The Hilti DX E72 is designed for efficient and reliable fastening. Always maintain a firm grip and stable stance during operation.

1. Prepare Work Surface: Ensure the material to be fastened into (concrete or steel) is clean, dry, and free of obstructions.
2. Position the Tool: Place the muzzle of the tool firmly and perpendicularly against the work surface at the desired fastening point. The tool requires sufficient contact pressure to activate.
3. Fire the Tool: While maintaining firm pressure against the surface, pull the trigger. The tool will fire, driving the fastener into the material.
4. Automatic Cartridge Ejection: The DX E72 features an automatic cartridge ejection system. The spent cartridge will be ejected after firing, preparing the tool for the next shot.
5. Reload: If more fasteners are needed, load a new fastener and, if necessary, a new cartridge.

Important: If the tool does not fire, keep it pressed against the surface for at least 30 seconds before attempting to remove it. This allows for potential delayed ignition. If it still doesn't fire, refer to the Troubleshooting section.
