What Causes a Nail Gun to Jam?

Nail guns can jam for several reasons. Some of the most common causes are:

Wrong-sized nails: To avoid a nail gun jam, using the correct nail size for the nail gun model is crucial. Using nails different than the recommended size for the specific nail gun can result in a jam.

Worn or damaged parts: The internal components of a nail gun, such as the driver, feeder, or magazine, can wear out or become damaged over time, causing the nail gun to jam.

Dirty or rusty nails: If the nails are dirty or rusty, they may not feed smoothly through the nail gun, causing a jam.

Misaligned nails: If the nails are not loaded properly in the magazine or are misaligned during firing, they can cause a jam.

Low air pressure: Insufficient air pressure in the compressor can lead to a nail gun jam, as the nails may not be able to penetrate the wood with enough force.

To avoid nail gun jams, it is important to use the correct size nails, keep the internal components of the nail gun clean and well-maintained, and ensure the air pressure is sufficient for the job.

Clearing a Jammed Nail Gun

Clearing a jammed nail gun can be dangerous, and it is important to take proper safety precautions. 

Before attempting to clear a jammed nail gun, make sure to disconnect the tool from its power source or remove its batteries.

Follow these steps to clear a jammed nail gun:

  1. Release the magazine: If your nail gun has a magazine release, use it to remove the magazine from the nail gun. This will give you better access to the jammed nail.
  2. Clear the jammed nail: Use a pair of pliers or a screwdriver to remove the jammed nail from the nail gun. Be careful not to damage the nail gun while doing this.
  3. Check for other obstructions: After removing the jammed nail, inspect the nail gun for any other obstructions, such as pieces of wood or debris. If you find any, use the pliers or screwdriver to remove them.
  4. Reassemble the nail gun: Once you have cleared the jam and removed any obstructions, reassemble the nail gun and test it to ensure it is functioning properly.

If you are unsure how to clear a jammed nail gun or feel uncomfortable doing it yourself, it is best to take the nail gun to a professional for repair.

Why is My Nail Gun Plunger Not Returning?

If your nail gun plunger is not returning, there are a few possible causes:

  1. Dirty or worn plunger: Dirt, debris, or wear and tear can cause the plunger to become stuck or not return properly. Cleaning the plunger and replacing any worn parts may solve the issue.
  2. Low air pressure: If the air pressure in the compressor is low, it may not provide enough force to return the plunger. Checking and adjusting the air pressure to the recommended level may solve the issue.
  3. Damaged or worn O-rings: The O-rings on the plunger can become worn or damaged over time, causing the plunger to stick or not return. Replacing the O-rings may solve the issue.
  4. Jammed nail or other debris: A jammed nail or debris in the nail gun can prevent the plunger from returning properly. Clearing any jams or debris may solve the issue.
  5. Broken driver blade: If the driver blade is broken, it may not be able to return the plunger properly. Replacing the driver blade may solve the issue.

If you cannot identify and fix the issue, it is best to take your nail gun to a professional for repair.

Frequently Asked Questions (FAQs)

Why does my nail gun shoot air but no nails?

A nail gun may shoot air instead of nails for a few reasons, such as an empty magazine, jammed nail, low air pressure, or worn parts. Checking the magazine, clearing any jammed nails, setting the recommended air pressure, or seeking professional repair can fix the problem.

Why won’t my nail gun hold air?

If a nail gun doesn’t hold air, it may be due to a leaking air hose, faulty trigger valve, broken seals, low air pressure, or a dirty air filter. Proper maintenance, inspection, and cleaning can prevent these issues. Check the owner’s manual or contact the manufacturer for guidance if needed.

What pressure/PSI should a nail gun be set at?

Generally, a nail gun’s recommended PSI range is between 70 and 120 psi (pounds per square inch).

Will a 3-gallon air compressor run a nail gun?

Yes, a 3-gallon air compressor can run a nail gun, but it may have some limitations depending on the type and size of the nail gun and the nature of the job.

A 3-gallon air compressor typically provides around 0.5 to 0.7 CFM (cubic feet per minute) of airflow, which may be enough for smaller or intermittent jobs with a finish nailer or a brad nailer. However, a larger air compressor with a higher CFM rating may be required for larger jobs requiring a framing or roofing nailer.
