How to Set Up the CRAFTSMAN CMCN618 Cordless Brad Nailer

Inspect the tool, magazine, contact trip, and battery for damage. Do not use the nailer if any safety component is cracked, bent, or missing.
Charge a compatible V20 battery using the appropriate charger. Remove the battery from the charger when charging is complete.
With the battery disconnected, press the magazine pusher latch and pull the magazine open.
Insert compatible 18-gauge brad nails with their points facing toward the front of the magazine and positioned in the nail channel.
Close the magazine until the latch locks securely. Never operate the tool with the magazine partially closed.
Install the charged battery until it clicks into place. Keep the trigger and contact trip away from objects during installation.
Turn the depth adjustment toward the desired setting and test-fire into scrap material. Adjust gradually until the nail head sits flush without sinking excessively.
Place the contact trip firmly against the workpiece, then pull the trigger. Release the contact trip and trigger after every shot.

Keep hands away from the nosepiece and never point the tool at yourself or another person. If the nailer does not fire, remove the battery before inspecting the magazine, fasteners, or jam-clear door. This tool does not use Bluetooth or wireless pairing; connectivity is limited to installing a compatible battery.

CRAFTSMAN CMCN618 Troubleshooting Guide

Nailer does not fire

Confirm that the battery is charged and fully seated. Check that the contact trip is completely depressed and that the magazine contains compatible nails. Release both controls after each shot, then try again.

Nails do not feed

Remove the battery and open the magazine. Verify that the nails are facing the correct direction, are within the 5/8-inch to 2-inch range, and are not bent or damaged. Clean debris from the nail channel and close the magazine until it locks.

Nail is driven too deeply or not deeply enough

Use the depth-of-drive adjustment and test the result on scrap material. Hard or soft wood, nail length, battery condition, and firing angle can affect the final depth.

Fastener jam

Disconnect the battery, remove remaining nails, and open the jam-clear door. Carefully remove the obstructing fastener with a suitable tool. Do not use excessive force or place fingers near the contact-trip mechanism.

Worklight operates but the tool will not drive

Check the battery charge, contact-trip position, magazine latch, and nail supply. If the tool still fails, stop using it and arrange qualified service.

CRAFTSMAN CMCN618 Pros and Cons

Advantages

Cordless portability: No compressor, air hose, or gas cartridge is required, which simplifies trim work in finished rooms and remote areas.
Useful fastener range: The 18-gauge magazine accepts brads from 5/8 inch to 2 inches for common molding, casing, cabinetry, and craft applications.
Adjustable nail depth: Depth control helps users set the nail head flush for cleaner finishing and reduced filler work.
Serviceable design: The sliding magazine and jam-clear door support routine loading and obstruction removal.
V20 compatibility: Owners of other compatible V20 tools can use the same battery platform.

Limitations

Battery dependent: Runtime and driving consistency depend on battery charge, capacity, temperature, material, and nail length.
Not a framing nailer: The tool is intended for light finish fastening, not structural framing or heavy construction work.
Tool-only packages vary: Some packages do not include a battery or charger, so users should verify the contents before setup.
Brushed motor design: Compared with some newer brushless cordless nailers, a brushed motor may offer less efficiency and may require more maintenance over extended use.

The CRAFTSMAN CMCN618 Gauge Cordless Brad Nailer suits users who value mobility and straightforward trim installation. A pneumatic nailer may be preferable for continuous high-volume work, while a heavier-duty cordless nailer is more appropriate for structural applications.

Faqs

How do I set up the Craftsman CMCN618 Gauge Cordless Brad Nailer for the first time?

Charge a compatible Craftsman V20 20V MAX lithium-ion battery, then remove the battery before loading fasteners. Use straight, adhesive-collated 18-gauge brad nails measuring 5/8 to 2 inches. Slide the nail strip into the magazine according to the loading markings until the follower locks behind it. Reinstall the battery, release the tool lock-off if equipped, and test the depth setting on scrap material before beginning the project.

Which brad nails are compatible with the Craftsman CMCN618 Gauge Cordless Brad Nailer?

The Craftsman CMCN618 cordless brad nailer is designed for 18-gauge straight brad nails from 5/8 to 2 inches long. Use clean, undamaged strips with the correct adhesive collation; staples, angled nails, and other gauges can cause feeding problems or damage. Select nail length based on the material thickness, allowing enough penetration for a secure hold without driving through the workpiece.

Why is my Craftsman CMCN618 Gauge Cordless Brad Nailer not firing?

First, remove the battery and check that the magazine contains the correct 18-gauge brad nails and that the follower moves freely. Confirm the battery is charged and fully seated. The contact safety must be pressed firmly against the work surface before the trigger can operate. If the tool still does not fire, inspect the magazine and nose for a jam, then clear it only with the battery removed.

How do I clear a jam in the Craftsman CMCN618 Gauge Cordless Brad Nailer?

Remove the battery before attempting any jam-clearing procedure. Empty the magazine, open the tool-free jam-clear access, and carefully remove the bent or stuck brad with pliers if necessary. Never place fingers in the firing path or pull the trigger while servicing the nose. Close the access panel, reload straight 18-gauge nails, and test the nailer on scrap material before returning to the project.

How can I adjust nail depth on the Craftsman CMCN618 Gauge Cordless Brad Nailer?

Use the tool-free depth-of-drive adjustment to control how far each brad enters the material. Begin with a shallow setting and drive a test nail into scrap matching the project surface. Increase depth gradually if the nail head remains proud; reduce it if the nail sinks below the surface or damages delicate trim. Material density, nail length, and battery charge can all affect the final result.

What should I do if the Craftsman CMCN618 Gauge Cordless Brad Nailer sinks nails too deeply?

Reduce the depth-of-drive setting and test again on a piece of matching scrap. Keep the nose perpendicular to the workpiece and press it firmly against the surface without excessive force. Confirm that the brad length is appropriate for the material and that the battery is properly seated. If inconsistent depth continues, inspect the nose and magazine for debris, damage, or a partially cleared jam.

How can I improve battery life and performance with the Craftsman CMCN618 Gauge Cordless Brad Nailer?

Use a fully charged Craftsman V20 20V MAX lithium-ion battery and keep the battery contacts clean and dry. Avoid repeatedly firing against unsuitable material or using nails outside the specified range, since both can increase motor strain. Work with a steady rhythm rather than rapidly cycling the trigger, and allow the tool to cool if it becomes unusually warm. Store batteries according to the battery manufacturer's instructions.

How should I maintain and store the Craftsman CMCN618 Gauge Cordless Brad Nailer?

Remove the battery and nails before cleaning or storing the nailer. Wipe dust from the housing, magazine, contact nose, and adjustment controls with a dry or slightly damp cloth; keep moisture away from electrical parts. Check regularly for loose hardware, damaged components, bent fasteners, or restricted magazine movement. Do not modify the tool or use unapproved lubricants. Store it in a dry, protected location with the battery removed.
