Loading Fasteners (Nails and Staples)
This 2-in-1 tool is compatible with 18GA staples and brad nails. The 100-fastener capacity magazine minimizes reloads.

Image: A quick 3-step guide demonstrating how to load fasteners: 1. Press the release button and pull down the magazine cover. 2. Load nails/staples into the magazine track with points facing down. 3. Press and hold the release button until the magazine clicks and locks.
- Press the magazine release button and pull down the magazine cover.
- Insert a strip of 18GA staples or brad nails into the magazine track. Ensure the points of the fasteners are facing downwards. For nails, load them all the way to the left towards the driving tip. For staples, load them all the way to the right of the slide.
- Push the magazine cover back until it clicks and locks into place.

Operating Instructions
Selecting Firing Mode
The nailer offers two firing modes for different applications:
- Single Firing Mode: For precise fastening. Press the safety contact tip against the workpiece, then pull the trigger.
- Contact Firing Mode: For higher efficiency and rapid, continuous nailing. Hold the trigger, then press the safety contact tip against the workpiece. The tool will fire each time the tip makes contact.

Image: Illustration of the two nailing modes: Single Firing (press tip, then pull trigger) for precision, and Contact Firing (hold trigger, then press tip) for speed. A note reiterates that the nailer will not fire unless the safety tip is fully engaged.

Adjusting Nail Depth
The adjustable nail depth feature allows you to adapt to different material thicknesses and desired fastener protrusion.
- Locate the depth adjustment wheel on top of the tool.
- Rotate the wheel to adjust the driving depth. Turn it one direction for deeper penetration and the other for shallower.
- Test on a scrap piece of material to achieve the desired depth before working on your project.

Using the LED Indicators
The tool is equipped with LED indicators to provide important status updates:
- Red On: Indicates low battery. Recharge the battery.
- Red Flashing: Indicates nails are jammed. Refer to the "Clearing Nail Jams" section.
- Green On: Indicates no nails in the magazine. Reload fasteners.

Safety Contact Tip
The safety contact tip is a critical safety feature designed to prevent accidental firing. The tool will only operate when the tip is pressed firmly against the work surface.

Maintenance
Clearing Nail Jams
If the LED indicator flashes red, it signifies a nail jam. Follow these steps to safely clear the jam:

Image: A visual guide for easy nail jam clearing: 1. Red flashing LED indicates a nail jam. 2. Remove the battery. 3. Open the magazine. 4. Remove the jammed nails/staples.
- Immediately remove the battery pack from the tool.
