NT50AE2 Hitachi brad nailer depth adjustment

the seal inside is ether out of place or cracked gun are cheap buy a new one

Make sure your using the right gauge brads for your gun, should have sticker on rail with required brad gauge, and max length. Sometimes a brad will get jammed under drive pin where you cant see, might have to remove allen screws over pin to get jammed brad out

This happens. The follower jumps over the nails and the magazine binds.

Step 1. Remove nails, unplug hose.
Step 2. Remove the bolt at the bottom of the magazine with a 2.5mm hex key.
Step 3. Remove the magazine while holding the nail follower in place to the magazine cover.
Step 4. Carefully remove the nail follower and gently extend the yellow warning indicator and follower spring.
Step 6. Inspect the nail follower. There should be 3 indentations that are stamped into nail follower face. This is the culprit.
Step 7. With a small punch, make these three indentations deeper.
Step 8. Assemble and test. Repeat if necessary.

Hope this helps.

Can u adjust the drive depth on the tip of the gun? My nailers all have a knob to adjust the drive depth. Also, what pressure are you using? I typically shoot mine between 90 and 120 psi. Hope this helps.

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.




Good Luck

Hello. To adjust the depth of the nail you have to increase or decrease the air pressure from the compressor. Look at the compressor and you will see a knob or dial that you can turn to increase or decrease the air pressure. Do this adjustment in small increments testing the nailer by driving nails into a scrap of the same material you will be driving the nails into on the actual job. Increasing the pressure will drive the nail deeper and decreasing the pressure will drive the nail less deep. Joe

A brad nailer in good working order, set to the deepest setting and using 125psi should almost shoot the brad through the wood. If you have been oiling the gun properly (three to four drops at he beginning of your work session and again in the afternoon if under constant use) then you probably have some worn o-rings inside the gun. Porter Cable makes a driver maintenance kit (PN1001 60062) for your gun that will make it work like new.

look on the front of the tool.there is a dial right where the plastic meets the yellow housing.also look closely and you should see a diagram on the plastic telling you whitch way to go.

A good-quality starter set, including both a compressor and a small nail gun, can be bought for around 200 US dollars (USD). More sophisticated models can reach 1000 USD or more. Optional features such as a hard-shell case, safety trigger, and depth adjustment can drive the price even higher. For one-time jobs, a nail gun can also be rented at hardware stores and home repair centers.
