Question about RTO PasLode 900420 Impulse Framing Nailer

Paslode 900420 piece fell out

I had a single nail stuck in track so I had to partially disassemble gun. As I was doing this , the lockout bar follower and a small spring fell out.

After looking at paslode schematic (part is #40 on chart), the part seems to be floating in the air and I have not figured out how to assemble gun with this part in place. Any help would be appreciated and a picture of assembled gun would be great.

Be sure to remove the metal nose piece that covers the lockout bar when assembled. It may be stuck to the other half of the gun. Replace the bar and the spring and put the metal nose piece in its position over the lockout bar. At this point the metal nose piece will be on the opposite side. This will allow you to replace the 2 halves carefully so as not to loose the spring.

Lockout Follower bar and spring location for Paslode 900420 Nailer

you can try going to and downloading a breakdown of this tool. The lockout bar and spring go under the metal plate on the side where the pusher spring is. You have to remove the nose piece (2 screws) and lift the metal plate. Towards the bottom there is a slot that the spring goes in and as you are holding the spring push on the back side and lay the lockout bar in place. Replace the metal plate and hold in place to ensure these parts more freely. Reassemble tool. Let me know if you need more assistance.

Paslode impulse 900420 cannot figure out where to put spring for lockout bar follower I know where the lockout bar goes. does not seem to be any space where the spring fits. can you tell me which...

it goes under the large plate, you need to remove the screws holding the nose in place (large black piece with screws on either side) sometimes this is a 2 piece part. Under the plate where the lockout bar sits is a small recess and you will need to start the spring and then push it into place with the lockout. Let me know if you need more assistance.

I have taken apart my paslode impulse framing nailer to remove a nail that had got lodged in the nail channel,i removed the lodged nail,but now have a part and a small spring that im not sure where they...

they go under the plate where the follower is. What you need to do is remove the screws that hold the channel to the side where the follower is located and then lift the steel plate up. Pull back on the follower and the lockout bar and spring fit into a recess that you will see (once you get it to this point you will see what I am talking about), set the spring and bar into the recess and push it a couple times to make sure installed properly. replace the laarge steel plate and hold in place while reassembing the nose piece (4 screws, 2 on each side) and then reassemble the rest of the tool. Let me know if you need more assistance. If I have helped you would you please vote accordingly, Thank you

Paslode gun will not engage the fan when tip depressed

if this is the framer, could be quite a few things. first do you have nails in the magazine, the safety might be bent not allowing full travel, the spark unit might be faulty. If you are comfortable with some partial disassembly, let me know and I will go into further detail for you on troubleshooting, you will need an allen wrench the size of the cap head screws. Let me know

How to remove follower on im 350

Remove the screw that ajoin the plastic halves. On the bottom of the gun, directly below the nail strips, there is a long greyish coloured cleat. This will slide backwards and allows the gun halves to seperate. ake care noticing where the parts are located within. There should be a dry-fire lockout tab, a small spring and load spring.

Friend took my 900420 nailer apart to clean it and when he got done, had a small spring about 3/16" x 1" left over. Does anyone have a clue where it might go?

Thin spring?
Goes in-between the Follower Guide and Button.
There are several Coil springs used in a Paslode 900420 framing nailer.

1.In-between the Upper Probe and the Lower Probe.
(Safety device you depress so the gun will shoot)
3.Lockout Bar
4.Follower Guide and Button

(There is a flat spring also. Goes in-between the Probe Stop and Probe Release)

Here let me show you,

My finish nail guns, 16 ga won't fire.

There is a little plastic piece inside above the trigger...usually this breaks. It touches a microswitch when the cylinder is closed all the way, allowing the nail to fire.

Paslode nail gun not firing

Yes you need to oil driver blade piston.
You need to check for spark. With no nail or gas in it. Take of main cylinder(4bolts on top, 2 bolts on nose. And then put in battery. And then push upper switch(behind roller at top) and the fan will come on. And then pull the trigger. You should have spark.

Paslode framing nailer loss of power.

Here's what I found at the Paslode Troubleshooting Site:
Tool will not cycle - fan runs, indicator light
is solid green.

Lockout bracket is stuck in lockout position.
Work-contacting element is bent, or build-up of
debris in track restricts operation.
Follower is not behind fasteners.
Fuel Cell empty.
Spark wire out of spark plug.
Spark plug is dirty.
No spark is generated.
Check lockout.

Remove and inspect lower probe. Clean and
lubricate track with Paslode Impulse® oil.
Repair or replace lower probe as required.
Position follower behind fasteners.
Replace fuel cell.
Remove cap and check spark lead, insert in
spark plug and replace cover.
Clean tool cylinder head and spark plug.

If this doesn't work, I suggest contacting Paslode directly 800-222-6990
