Be sure your nail gun is operating at the correct air pressure

Low air pressure can cause the following problems:

  • Gun does not work at all
  • Driver won’t retract after firing
  • Driver retracts slowly
  • Poorly sunk nails
  • Splitting wood

High air pressure can cause these symptoms:

  • Air leaks
  • Broken parts or casing
  • Heavy wear



All guns only need a couple of drops before each day of use or per 1,000 nails

Low lubrication symptoms:

  • Air leaks
  • Driver jams
  • Pusher guide malfunctions
  • Nail loading errors
  • Not firing


Correct Nails

  • Nail jams
  • Misfires
