Reassembly Guidance

To facilitate reassembly, pay close attention to the following:

Note the wire routing and position within wire guides and traps during disassembly.
Ensure all components of the electronics kit are seated firmly and squarely in the handle recesses.
Prevent pinched wires by ensuring all wires and sleeves are pressed completely down in wire guides and traps.
Before securing the handle cover, verify there are no interferences.
Prior to installing the battery, check for proper functionality of the shuttle and triggers.
After installing the battery, depress the switch trigger to confirm the tool is operating correctly.
