You also need to be particularly careful about the porter cable staple gun barrel since it might have something stuck inside the barrel, or the pins might be getting damaged or bent, which might cause you to have some issues.

That is why you will need to make sure that you disassemble the battery and the magazine properly.

  1. Check The Magazine

At this point, you need to check the magazine to figure out the issue with the unit not working.

It can be more than just a little challenging to limit issues with the magazine, and you will need to make sure that the hardware itself is in good shape.

Sometimes, the fix is as simple as readjusting the magazine. However, if the magazine seems to be clogged and you’re not that lucky with a fix, then the situation can be a bit more complete.

You will have to make an investment in the new magazine, and there are no quick fixes here.


While some users have pointed out that gently tapping the unit is more than enough to fix the minor clogging issues, this fix is not that reliable.

You can always try your luck, but the more consistent solution here is to get a new magazine by reaching out to the dealer.

  1. Use Lubricant

It is also possible that you just need to lube up the unit to get a consistent response from the device. There are no quick methods when you’re dealing with a unit in poor condition.

The only reasonable thing that you can do to fix these issues is to access the head valve and lube it up.


Using lubricant might seem like a basic fix, but it has helped too many owners get through minor complications with the jammed unit.

From there, you can also check on the grease status. The situation with grease mixing up with debris to develop gunk on the pivot points is pretty common.

It will lead to a ton of issues down the road, and you will not be able to get any response out of the system.

So, all that you need to do is to keep using lubricant and address this issue by removing the old chunks of grease. 


Hopefully, all errors will be addressed right here, and you will not have to deal with more errors down the road.

Fixing the unit is pretty easy as long as you’re keeping track of these basic maintenance cycles.

  1. Check the Trigger

Next, you need to also check the trigger for possible issues. Over time, the trigger can get stiff or damaged.

This is especially true if the conditions around the workshop are a bit harsh and the moisture content is a bit high. So, you will have to replace the switch assembly to get the right response.

Even when you’re keeping track of all the points above, you will not get the staple gun to work when the switch is not engaging the tool.

If that is the case, you will just have to fix the trigger and make sure that the gun gets engaged as soon as you press the button.

If you’re lucky, you will also be able to fix this issue by blasting around the trigger with compressed air.

That will loosen up the debris behind the unit, and you will have a decent shot at getting the right response from this device. 

  1. Claim Warranty

He will not only help you figure out the issue, but he will also guide you through each step. From there, you can also demand a replacement if the unit is defective.

Wrapping Up

Ideally, you should be able to fix the situation with the Porter Cable staple gun by checking up on the battery status.


Even if you follow through with all of the maintenance cycles, fixing the battery can be a bit hard at times. You will need to make sure that the power going into the system is optimal. 

Otherwise, you will remain stuck in these issues, and the unit will not respond to any input. From there, you can go about fixing the hardware side of things and make sure that the barrel is clean.

If there is gunk or debris stuck in the barrel, then you will not be able to fix the unit until the chamber is clean.

From there, you can also check for cracks and damaged sections. Issues with hardware damage can be pretty hard to fix at times.
