Safety Information
Always observe basic safety precautions to reduce the risk of fire, electric shock, and personal injury when operating power tools. Keep this manual for future reference.
- Work Area Safety: Keep the work area clean and well-lit. Cluttered or dark areas invite accidents. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust.
- Electrical Safety: Avoid body contact with earthed or grounded surfaces such as pipes, radiators, ranges, and refrigerators. There is an increased risk of electric shock if your body is earthed or grounded.
- Personal Safety: Always wear eye protection (safety glasses or goggles) and hearing protection. Use a dust mask in dusty conditions. Dress properly; avoid loose clothing or jewelry that can get caught in moving parts.
- Tool Use and Care: Do not force the tool. Use the correct tool for your application. Disconnect the battery pack from the tool before making any adjustments, changing accessories, or storing power tools. Store idle tools out of the reach of children.
- Battery Tool Use and Care: Recharge only with the charger specified by the manufacturer. Use power tools only with specifically designated battery packs.

Setup
1. Battery Installation
The Makita XNB02Z operates on an 18V LXT Lithium-Ion battery (sold separately).
- Ensure the tool is switched off and the trigger lock is engaged.
- Align the battery pack with the battery housing on the tool.
- Slide the battery into the housing until it clicks securely into place.
- To remove, press the release button on the battery and slide it out.

2. Loading Nails
The nailer uses standard 16 gauge straight finish nails from 1" to 2-1/2" in length.
- Ensure the tool is switched off and the battery is removed.
- Pull the magazine pusher back until it locks into place.
- Insert a strip of nails into the magazine with the nail points facing down.
- Release the magazine pusher, allowing it to push the nails forward until they are seated correctly.

3. Adjusting Depth
The XNB02Z features a "tool-less" depth adjustment for precise flush and countersink finishes.
- Locate the depth adjustment dial or lever near the nose of the tool.
- Rotate the dial or move the lever to increase or decrease the nail driving depth. Test on a scrap piece of material to achieve the desired depth.
Operating Instructions
1. Powering On/Off and Trigger Lock
To power on the tool, ensure a charged battery is inserted. The tool does not have a separate power switch; it activates when the trigger is pulled (after disengaging the trigger lock).
- Engage Trigger Lock: Push the trigger lock button to the locked position to prevent accidental firing.
- Disengage Trigger Lock: Push the trigger lock button to the unlocked position to enable operation.

2. Selecting Actuation Mode
The 2-mode selective actuation switch allows you to choose between sequential and contact actuation.
- Sequential Actuation: For precise nail placement. The contact arm must be pressed against the workpiece, and then the trigger pulled to fire a single nail.
- Contact Actuation: For rapid nailing. Hold the trigger, then press the contact arm against the workpiece to fire a nail. Nails will fire as long as the trigger is held and the contact arm is depressed.
3. Nailing Procedure
- Ensure the battery is charged and nails are loaded.
- Disengage the trigger lock.
- Select the desired actuation mode.
- Place the nose of the nailer firmly against the workpiece at the desired nailing location.
- Pull the trigger to drive the nail. The built-in LED light will illuminate the work area.
- Release the trigger and lift the tool from the workpiece.

4. Anti-Dry Fire Mechanism
The anti-dry fire mechanism prevents the tool from firing when the nail magazine is empty or nearly empty. This protects the tool and prevents damage to the workpiece from blank firing. Reload nails when the mechanism engages.
Maintenance
Regular maintenance ensures optimal performance and extends the life of your tool.
- Cleaning: Keep the tool clean and free of dust and debris. Use a dry cloth to wipe down the exterior. Do not use harsh chemicals or solvents.
- Nose Clearing: If a nail jam occurs, utilize the "tool-less" quick clear nose design. Ensure the battery is removed before attempting to clear any jams. Open the nose assembly, remove the jammed nail, and close securely.
- Battery Care: Store batteries in a cool, dry place. Do not store fully discharged batteries for extended periods.
- Inspection: Periodically inspect the tool for any signs of damage, loose screws, or worn parts. Contact an authorized service center for repairs.
