Introduction

The trigger is used to activate the Hackzall’s electric 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 liquid damage, drop damage, or wear.

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. Be sure to follow the recommendations in the ++project safety guide++ when soldering to prevent injury or damaged components.

Before starting your trigger replacement, ensure that the battery is fully disconnected from the tool.
