Using your Milwaukee 48 - 08 - 2745 Extended Capacity Magazine is a breeze. First, make sure your nailer is the M18 FUEL™ 30 Degree Framing Nailer (2744 - 20) as this accessory is only compatible with it. To load nails, use the bottom - load design. Just insert two full strips of nails according to the size and collation angle shown on the magazine. The magazine accepts nail lengths from 2' to 3 1/2' and diameters from .113' to .131' with collation angles between 30° and 34°. Installation is simple and quick, so you can get to work right away. When it comes to maintenance, keep it clean after each use. Wipe off any dirt or debris. Since it's made of magnesium, it's durable but still be careful not to drop it or subject it to heavy impacts. And remember, it comes with a 1 - year manufacturer's warranty, so if you have any issues, you're covered.
