Advantages of the DWMC150

Maximum Productivity in Confined Spaces

The compact 10.5-inch height is a significant advantage on job sites. Unlike traditional 12- to 14-inch nailers, the DWMC150 easily accesses 12-inch spaces between joists, eliminating the need for tedious manual nailing and saving hours of labor on every framing project.

Professional Precision with Exposed Nail Tip

DeWalt's unique exposed nail tip system allows for millimeter-precise positioning before each shot. This eliminates costly placement errors and ensures a perfect fit for metal connectors every time, reducing nail waste and rework.

Balance and Comfort All Day Long

Weighing only 4.6 pounds and featuring a perfectly balanced magazine, this nailer drastically reduces fatigue on long workdays. The optimized center of gravity and ergonomic, non-slip grip allow for precise control, even in awkward positions.

DeWalt's proven reliability

Professional-grade construction with hardened steel internal components and a die-cast aluminum housing. The anti-jam system and low nail indicator keep your productivity flowing smoothly, project after project, without frustrating interruptions.

First Use

Activating your new DWMC150 nail gun:

1. Initial Inspection

Unpack the nailer and visually inspect all components for any shipping damage. Check that the magazine slides freely and that the rafter hook is securely attached. Read the entire instruction manual before first use.

2. Initial Lubrication

Add 4 to 6 drops of DeWalt pneumatic oil to the air fitting before first connecting it to the compressor. This initial lubrication protects internal components and ensures optimal performance from the very first shot.

3. Connecting to the Compressor

Connect a clean, leak-free air hose to your compressor set between 70 and 120 PSI. Start at 90 PSI for most applications, then adjust according to the type of metal connector and the thickness of the wood. Perform a few test shots on a scrap piece before starting your project.

4. Loading the Magazine

Slide a strip of metal connector nails into the inline magazine until it is fully engaged. Ensure the nails are oriented correctly according to the markings engraved on the magazine. Close the retaining latch and fire a test shot.

Daily Maintenance

To maximize the lifespan of your nail gun:

After each use:

• Add 3 to 5 drops of pneumatic oil to the air fitting before storing the tool.
• Empty the magazine completely of any remaining nails to prevent oxidation.
• Wipe the outside of the nail gun with a clean cloth to remove dust and debris
• Purge any residual air by disconnecting the hose and pulling the trigger.

Lubrication management:

• Lubricate daily before each work period to maintain optimal performance
• Use only pneumatic tool oil, never engine oil
• In Quebec's cold climate (below 0°C), double the lubrication frequency.

Rotation and inspection recommended:

• Inspect the piston O-rings weekly for wear or cracks.
• Check monthly that all visible screws are tight
• Immediately replace any damaged components with genuine DeWalt parts

Cleaning and Maintenance

Thorough quarterly cleaning:

Magazine and feeding mechanism

Remove the magazine and clean the inside with a stiff brush and compressed air. Remove any accumulated wood residue, dust, or rust. Apply a thin coat of dry lubricant to the magazine rails.

Nailing tip and firing chamber

Clean the firing chamber with a cloth dampened with mild solvent to remove lubricant residue and compressed wood. Inspect the exposed nail tip for any deformation or excessive wear.

Exhaust and air vents

Check that the adjustable exhaust is not obstructed by debris. Clean all air ports with compressed air to maintain constant pressure.

Joints and fittings

Inspect all O-rings and replace any that show signs of hardening, cracking, or wear. Apply a thin layer of silicone grease to the new O-rings.

Precautions for Use

For your safety:

Avoid excessive pressure

Never exceed 120 PSI, as this could damage internal components and compromise safety. Excessive pressure can also drive the nails too deeply into the metal connectors.

Wear protective equipment

Always wear safety glasses, hearing protection, and work gloves when using this product. Metal splinters and ricocheting nails can cause serious injury.

Never modify the tool

Any modification to the safety mechanism or triggering system voids the warranty and creates a risk of accidents. Use only genuine DeWalt replacement parts.

Maintain a firm grip

Always hold the nail gun firmly with both hands when firing. Recoil can cause a loss of control in awkward positions between joists.

Disconnect before maintenance

Always disconnect the air hose before making any adjustments, cleaning, or changing nails. Keep your finger off the trigger when loading.

Storage Tips

Short-term storage (less than 1 week):

• Store in a dry place at room temperature between 5°C and 30°C
• Leave a light coating of oil on the tool for protection against moisture.
• Store in the toolbox or carrying case with an empty magazine
• Keep away from sources of heat and excessive humidity

Long-term storage (more than 1 week):

• Lubricate all moving parts generously before storage
• Store in a dry place with humidity control if possible
• Pack in a plastic bag with a desiccant packet to prevent oxidation
• Check the condition of the tool every 30 days and re-lubricate if necessary.

Winter storage in Quebec:

• Never leave the nail gun in an unheated vehicle in sub-zero temperatures.
• If cold storage is unavoidable, allow the tool to warm up gradually before use.
• Lubricate immediately after exposure to cold to dispel any condensation
• Use a special cold-weather tire oil if working regularly below 0°C.

With proper storage and maintenance, your DWMC150 nail gun will maintain peak performance for many years of heavy-duty service.
