Extended Product Information

FAQs

What type of nails does the SA791 use?

The Sealey SA791 uses 18-gauge nails with lengths ranging from 3/8"" to 2"" (10-50mm).

What is the required air pressure for this nail gun?

The operating pressure range for the SA791 is 60-100psi.

Does it come with an air compressor?

No, an air compressor and air hose are required but not included with the Sealey SA791.

How do I adjust the depth of the nails?

There is a thumbscrew adjustment located on the tool specifically for setting the drive depth of the nails.

What does 'contact actuation' mean?

Contact actuation means the nail is fired when the safety contact nose is pressed against the work surface and the trigger is pulled. This allows for rapid nailing.

How often should I lubricate the tool?

It is recommended to add 1-2 drops of air tool oil to the air inlet before each use or after extended periods of non-use.

Can I use this for heavy-duty framing?

While it can handle nails up to 50mm, it is primarily designed for lighter tasks, trim work, and finishing. For heavy-duty framing requiring larger nails or more power, a different gauge or type of nailer might be more suitable.

Troubleshooting

Nail gun not firing.

Check air pressure is within the 60-100psi range. Ensure the air hose is securely connected. Verify the tool is pressed against the work surface for contact actuation. Check for nail jams in the magazine or driver track.

Nails not fully driving or countersinking.

Increase the operating air pressure (within the 100psi limit). Adjust the drive depth thumbscrew to a deeper setting. Ensure you are using the correct nail length for the material.

Air leaking from the tool.

Disconnect the air supply. Check all hose connections for tightness. Inspect the tool for visible cracks or damage. If leakage persists, internal seals may need servicing.

Frequent nail jams.

Ensure you are using the correct gauge (18) and length (10-50mm) of nails. Verify the nails are loaded correctly and the magazine feeder is clean. Do not force nails into the magazine.

Pros and Cons

Setup, Compatibility & Care

Setup:

  1. Connect Air Supply: Attach a compatible air hose (not included) to the 1/4""BSP air inlet. Ensure the compressor is set to the recommended operating pressure range of 60-100psi.
  2. Lubrication: Before first use and periodically, add 1-2 drops of specialized air tool oil into the air inlet to lubricate internal mechanisms.
  3. Nail Loading: Open the magazine by sliding the feeder, insert the appropriate 18-gauge nails (10-50mm), and close the magazine securely.
  4. Depth Adjustment: Use the thumbscrew to set the desired nail drive depth. Test on scrap material.

Compatibility:

  • Nails: Compatible with 18-gauge nails ranging from 3/8"" to 2"" (10-50mm).
  • Air Pressure: Requires 60-100psi operating pressure.
  • Air Inlet: Standard 1/4""BSP.

Care:

  • Cleaning: After each use, wipe down the exterior with a dry or slightly damp cloth. Ensure the tool is disconnected from the air supply before cleaning.
  • Maintenance: Periodically check for debris in the magazine and near the firing mechanism. Ensure the exhaust port is clear.
  • Storage: Store the nail gun in its supplied case in a dry environment when not in use. Disconnect the air hose after use.
