Some of the steps in the build of this kit require the snipping component legs. If
you’re building this kit on your own, or with a someone else, we

STRONGLY

recommend whoever is present is wearing safety glasses. When the legs are
snipped, the can fly off in unpredictable directions, at a high speed. Also, be sure to
follow the safety instructions that came along with your soldering iron.

Wash your

hands

after handling solder. Especially before eating. Be safe, and enjoy.
