Setup and Compatibility
Before using the TTBW-158 tool, it is crucial to verify the size and type of the barrel fastener. This tool is exclusively designed for Highfield 93180128 and 93180124 #6 flat head barrel fasteners with an inside diameter of 0.158 inches or larger.

Operating Instructions
The TTBW-158 tool features a smooth plunger operation and a heavy-duty spring for quick and easy engagement with compatible barrel fasteners.
- Inspect the Fastener: Ensure the barrel fastener is clean and free of obstructions. Confirm it is one of the compatible Highfield #6 types (93180128 or 93180124).
- Insert the Tool: Align the tip of the TTBW-158 tool with the opening of the barrel fastener. Gently insert the tool until it seats properly.
- Engage the Plunger: Press the plunger mechanism on the tool. This action will engage the internal locking mechanism of the barrel fastener, allowing it to be unlocked.
- Remove the Fastener: Once the plunger is engaged, the barrel fastener can be removed.
- Disengage the Tool: After removing the fastener, release the plunger to disengage the tool.

Troubleshooting
If the TTBW-158 tool is not functioning as expected, consider the following:
- Incorrect Fastener Type: This tool is designed ONLY for Highfield 93180128 and 93180124 #6 flat head barrel fasteners. It will NOT work on most other fasteners, including those for electric & gas meters, fasteners with raised heads, or high-security barrel fasteners.
- Incorrect Fastener Size: Ensure the fastener has an inside diameter of 0.158 inches or larger. If the fastener is too small or too large, the tool will not engage properly.
- Obstructions: Check for any debris or foreign objects within the barrel fastener or on the tool's tip that might prevent proper engagement.
- Tool Damage: Inspect the tool for any visible damage, such as a bent tip or a malfunctioning plunger mechanism. If damaged, the tool may need replacement.
