Insert the syringe

Load the uncapped syringe — hands off the firing button.

1. Remove the needle's cap, then gently insert the uncapped syringe into the large end of Part A.
2. Gently insert the syringe's plunger into Part B — do not touch the firing button.
3. Screw Part A clockwise back onto Part B — do not over-tighten, and do not touch the firing button.
