Question about Dewalt D51844 Framing Nailer
Ran a few trial nails on this reconditioned unit. Went in okay, but I unloaded, disconnected, and increased depth.
Now, when I try to fire, I feel air release at trigger (on my fingers) when I depress the trigger. I'm dead in the water. Running about 100psi.
What am I doing wrong, or did this unit fail in the first ten minutes?
Adjusting the depth of the nail also changes the amount of pressure that is applied to the trigger pin. This is not actually a problem with the adjustment, however indicates that the orings in the gun are not completely sealing or is lacking lubricant. Adjust depth so that maximum pressure is asserted against the trigger pin. The trigger pin must be pushed all the way in very quickly to fire the gun. Test by removing the trigger and depressing the trigger pin by hand all the way in quickly. Enjoy

The depth to which a fastener is driven is controlled by the depth adjustment
knob (A) Fig. 19 below. The depth of drive is factory adjusted to a nomimal setting.
Test fire a fastener and check depth. If
a change is desired, rotate the
adjustment knob (A) Fig. 19: the
adjustment knob has detents every 1/4
turn. Rotate the knob clockwise (see
Fig. 19), to increase the depth of drive,
rotate the knob counterclockwise to
decrease the depth of drive. Test fire
another fastener and check depth.
Repeat as necessary to achieve
desired results. The amount of air pressure required will vary depending on the
size of the fastener and the material being fastened. Experiment with the air
pressure setting to determine the lowest setting that will consistently perform
the job at hand. Air pressure in excess of that required can cause premature
wear and/or damage to the tool.
