| If you notice that the trigger on your Milwaukee Hackzall 2625-20 is working intermittently or not working at all, this guide is for you. This failure can occur due to water damage or drop damage. The following steps will walk through removing the trigger assembly and reinstalling the new trigger assembly. To do so, knowledge of soldering is required to disconnect and reinstall the power connections onto the trigger assembly. The tools required to perform this task are a TR10 Torx Security bit, TR9 Torx Security bit, T15 Torx bit, and a soldering workstation. |
| If the trigger assembly on your Milwaukee Hackzall 2625-20 is working intermittently or not at all, use this guide to replace the trigger assembly. |

| The trigger is used to activate the Hackzall's motor. If the tool does not turn on when you pull the trigger there may be an electrical or mechanical failure in the trigger assembly, which may occur due to water damage or drop damage. |
|
| Step 2 for this guide requires you to desolder the connections on the trigger before reinstallation. After the trigger is removed, you will need to resolder the trigger connections. For supplemental information on soldering and desoldering connections, view this [guide|750|guide|new_window=true]. Be sure to follow the recommendations in the [link|https://edu.ifixit.com/project-safety?rq=esd#tool-safety|project safety guide] when soldering to prevent injury or damaged components. |
