How to use an air nailer
Updated: 21 October 2026
The gun is on the bench, the compressor is in the hall, and the first mistake is connecting the hose before you know which nail is in the magazine. This is how to use an air nailer once you already own one: couple the fitting, set the regulator at the bottom of the range printed on that gun, load a matching fastener, and fire into scrap before you touch the skirting. Air stays off until the nose is on the work, and it comes off again before you open a jam. Model choice stays on the [air nailer comparison](/hub/staplers-and-nail-guns/air-nailer). Peter F. followed the Health and Safety Executive nail-gun page, Air Supply’s compressor setup, and Nailfast’s oil advice. The plate on your gun overrides any number here.

Connect the hose and set the regulator
Start with the compressor switched off and your finger off the trigger. Fit the coupler until it clicks, then run the compressor and listen at the joint. A hiss is a leak, not a pressure problem. WORKPRO reviewers often found that the male connector in the box did not match a common UK hose, naming PCL, BSP, or a Euro 1/4 inch fitting. If it will not click, change the fitting. Several meite guns state a 1/4 inch NPT inlet, which is a different thread.
Set the regulator at the low end of the band printed on the gun, then test. Brad listings in this set cluster around 60–100 PSI or 70–100 PSI. The meite CN55 states 85–120 PSI, a coil-gun figure. A Garden Review note suggests starting a brad nailer around 60–70 PSI on MDF and softwood. That is their rule of thumb, not a measurement of these ASINs. If the listing prints no pressure, as with the Jovant and the CN65, do not invent one. If you have not bought the compressor yet, that gap is on the air nailer buying guide.
Load the right fastener
The gauge and the length have to match the gun. An 18-gauge brad will not feed in the meite MP635B, which the listing limits to 23-gauge pins from 12 mm to 35 mm. A 16-gauge finish nail will not feed in an F50C. Type 90 staples belong in the WORKPRO or the Tacwise, not in a nail-only magazine. Brad magazines here are about 100 fasteners. A coil magazine on the CN55 is up to 400.
Point the nose away from you while the stick goes in, and seat the follower so the strip cannot slide back out. If you are unsure whether the piece is a brad or a pin, read brad nailer or pin nailer before you force it. Nails are in the box only on the kits that say so. A 32 mm maximum, where the F32 stops, can be short once the nail has to pass thick skirting. A 50 mm brad is not automatically right for a thin architrave.
Plant the nose, then fire a test
Use an offcut of the same material. Where the gun has a contact safety, the nose has to be planted before the trigger will fire. The F50C listings state a safety lock. The WORKPRO states a contact safety switch. The Tacwise states a safety contact tip and contact-trip firing. Reviewers of the F32, including UK reviewers, say there is no safety foot, so the trigger is live as soon as air is connected.
A head sitting proud means the pressure is low, the nail is long for the depth setting, or the timber is harder than you imagined. A head that blows through means you are too high, or the nail is too long. Raise or lower the regulator in small steps inside the printed band, and use a depth wheel before you chase the problem with more pressure. UK reviewers of the CN55 say that gun has no depth gauge. Do not nail so close to an edge that the fastener can deflect. The setting sequence for painted trim is on air nailer for skirting. Bump-firing, nose down and trigger held, is the wrong habit for anything larger than short nails and small staples.
Oil, jams, and when to disconnect
If it jams, the hose comes off before the nose comes open. Disconnect the airline, point the gun away, and fire the trigger once into a safe space so the valve can exhaust. Only then release the magazine or the nose plate. Air Supply and the HSE both put the disconnect before maintenance.
Oil is general trade practice, not a dose printed on these ASINs. Nailfast describes a few drops of air-tool oil at the inlet before a session. Drain the compressor tank when you finish. The Tacwise kit includes a bottle of oil. The other listings do not. Stop and disconnect if the gun fires more than once for one trigger pull. The UK review of the meite CN65 says that after about 30 fence-panel nails the gun kept firing, and the buyer returned it. That is one report in a file of five ratings, not a failure rate. Put on eye protection before the first shot, and do not carry the gun from room to room with the airline live.
Common questions
What PSI should I set?
Use the band printed on your gun, starting at the low end. Brad guns in this set state about 60–100 PSI or 70–100 PSI. The CN55 states 85–120 PSI. A compressor article’s 60–70 PSI start on MDF is a rule of thumb, not a setting for every ASIN. If your listing prints no pressure, do not copy another model. Raise the regulator in small steps after a scrap test, and stop at the stated maximum.
How do I know the nail is the right depth?
The head should sit just below the surface on a scrap of the same board, without blowing through the face. Proud means a little more pressure or a depth-wheel change, still inside the printed band. Blown through means too much pressure or too long a nail. One F50C reviewer said house skirting nails buried. That is one report, not a trial, so your offcut still decides.
How often do I oil it?
A few drops of air-tool oil at the inlet before you work is the Nailfast practice we are passing on. These listings do not print a service interval, so we are not inventing one. The Tacwise kit is the row that includes oil. Drain the compressor when you pack up. Oil does not fix a wrong coupler or a jam that you are clearing on a live hose.
What do I do if it jams?
Disconnect the airline first, then exhaust the gun away from you, then open the nose. Do not pick at a bent brad while the hose is attached. Check that the next strip is the gauge the gun accepts. An 18-gauge brad in the MP635B, or a staple in a nail-only gun, will jam again. If the driver is bent, stop rather than forcing the next shot.
Can I bump-fire along a skirting board?
Not as a default. Plant the nose, fire once, and move. The HSE reserves repeat fire for short nails and small staples, and it says not to use it for large construction nails. Contact-trip guns such as the Tacwise can fire again as soon as the nose is pressed if the trigger is still held. That is faster, and it is also how a second nail lands where you did not look.
When should I stop and not keep raising the pressure?
Stop when you are already at the top of the band on the gun and the nail is still proud. The nail may be the wrong length, the timber may be too hard, or the depth wheel may be set deep. Stop immediately if the gun double-fires, if a live trigger is making you rush, or if you are about to fix something structural. More PSI will not turn a brad into a framing nail.
