Setup
1. Staple Selection
The Arrow JT27 uses Arrow JT21 series thin wire staples. These are available in 1/4" (6mm), 5/16" (8mm), and 3/8" (10mm) leg lengths. Selecting the correct staple length is crucial for effective fastening and depends on the thickness and type of material being stapled.

- Locate the bottom-load magazine at the rear of the tool.
- Press the pinch release mechanism to open the magazine.
