What to do if fasteners jam in my DeWalt Nail Gun?
- M
  molly83Aug 21, 2025
  If fasteners are jamming in your DeWalt Nail Gun, it could be due to a worn driver channel, wrong-sized fasteners, or bent/damaged fasteners. Loose magazine/nose screws or a broken/chipped driver can also cause this issue. To fix this: * Replace the fixed nose if the driver channel is worn. * Use only recommended fasteners. * Discontinue using bent or damaged fasteners. * Tighten all screws on the magazine and nose. * Replace the driver if it's broken or chipped.

What should I do if my DeWalt DWMC150 is skipping fasteners and intermittently feeding?
- S
  Stephen FitzpatrickAug 26, 2025
  If your DeWalt Nail Gun is skipping fasteners and intermittently feeding, it could be due to a damaged pusher spring, the tool being dry and lacking lubrication, or a worn driver piston O-ring. An air restriction or inadequate airflow through the socket and plug, dirt/grime in the driver channel, or a worn bumper can also cause this. To resolve this: * Replace the spring if the pusher spring is damaged. * Use DEWALT pneumatic tool oil to lubricate the tool. * Replace the O-ring and check the driver if the driver piston O-ring is worn. * Replace the quick disconnect fittings if there's an air restriction. * Disassemble and clean the driver and sleeve to remove dirt/grime. * Replace the bumper and check the driver and driver piston O-ring if the bumper is worn.

What causes a DeWalt DWMC150 Nail Gun to miss the metal connector hole?
- J
  jennifer27Sep 1, 2025
  If your DeWalt Nail Gun is missing the metal connector hole, it could be due to a damaged moveable nose, a nail not fully positioned in the drive channel, or the hole not properly located with the point of the nail. To fix this: * Replace the moveable nose if it's damaged. * Check for debris or collation in the drive channel and remove it if necessary. * Place the nail point in the metal connector hole before firing.

Why is air leaking from the CT housing of my DeWalt DWMC150?
- C
  Chad DodsonSep 4, 2025
  If the CT housing of your DeWalt Nail Gun is leaking air, it could be due to a cut or cracked CT housing O-ring, a cut or cracked shuttle O-ring, or a loosened or damaged CT housing plate. To fix this: * Replace the CT housing assembly if the CT housing O-ring is cut or cracked. * Replace the O-ring if the shuttle O-ring is cut or cracked. * Replace the CT housing assembly if the CT housing plate is loosened or damaged.

Why does my DeWalt DWMC150 have a nail point not visible?
- C
  Cesar GriffinSep 6, 2025
  If the nail point is not visible on your DeWalt Nail Gun, it could be due to a depressed trigger stem, a broken nose spring, a nail jammed in the drive channel, a broken or missing cam spring, a jammed cam/shuttle, or having less than 5 nails in the tool, causing it to be in lockout mode. To resolve this: * Release the trigger, disconnect and reconnect the air, and replace the trigger stem if it's depressed. * Replace the nose spring if it's broken. * Disconnect the air and clear the jam if a nail is jammed in the drive channel. * Replace the cam spring if it's broken or missing. * Disconnect the air, remove the cover, and separate the cam and shuttle if they are jammed. * Disconnect from the air and add a new strip of nails if there are less than 5 nails in the tool.
