In this blog post, we’ll go through the basics of troubleshooting and fixing staples guns so you can get back to using yours quickly!

How to Fix a Staple Gun Spring

Where Does the Small Spring Go in a Stapler?

The small spring in a stapler is located at the back of the device. It can generally be seen if you flip the stapler upside down and peer inside. The spring looks like a coil, usually made from metal or plastic, which helps to provide tension so that the staples are pushed out when pressure is applied. If this spring is damaged or missing, the stapler will be unable to function properly. Replacing the spring can help restore your stapler to working order.

In order to find a replacement spring for your stapler, you’ll need to know the make and model of your device. Once you have this information, head online and search for a replacement spring that matches the specifications of your specific stapler. Make sure you read the reviews before purchasing so that you are sure it will fit correctly.

If replacing the small spring does not fix your stapling problem, there may be other issues at play. Check out our guide on “How to Fix a Staple Gun Spring” for more tips and tricks on restoring your stapler to full working order.

10 Methods How to Fix a Staple Gun Spring

1. Check the Spring

The first thing you should do is check the spring to see if it is broken or damaged in any way. If the spring is damaged, it will need to be replaced. You can purchase a new spring from your local hardware store or online. If the spring is not damaged, then you will need to move on to the next step. Try to avoid using your staple gun if the spring is broken or damaged in any way, as it could cause damage to the gun.

You Can Purchase a New Spring

It’s also important to note that the spring may not always be visibly damaged, but it could still be the cause of your stapler’s malfunction. In this case, you will need to test and troubleshoot other potential issues before replacing the spring.

2. Check the Trigger

The next thing you should check is the trigger. If the trigger is not working properly, it could cause the staple gun to misfire. You can usually tell if the trigger is not working properly by looking at it. If there are any signs of wear or damage, you will need to replace the trigger. To do this, remove the screws holding the trigger in place and then replace them with a new one. You may need to use a screwdriver for this.

It’s important to be gentle when removing and replacing the trigger, as it is a delicate part that can easily break if handled too roughly. You may also need to refer to the manual for your specific staple gun model, as some triggers can be more complex to replace than others.

3. Clean the Gun

Another potential cause of a misfiring staple gun is dirt or debris build-up in the gun. Be sure to clean the gun thoroughly before troubleshooting any further. Using compressed air, blow through the gun to remove any loose debris. To clean out hard-to-reach areas, use an old toothbrush or pipe cleaner. Be sure to place a towel or cloth underneath the gun when cleaning it, as dirt and debris may fall out during the process. Once the gun has been thoroughly cleaned, dry it off with a soft cloth or paper towel. Finally, lightly lubricate any moving parts with a few drops of gun oil.

It’s important to keep your staple gun clean and well-maintained to avoid any potential issues with the spring or other parts of the device. Regularly cleaning and lubricating your staple gun can help prolong its lifespan and prevent any malfunctions.

4. Replace the Staples

If the staples are old or damaged, they could be causing the staple gun to misfire. Try replacing the staples with new ones to see if that fixes the problem. Before you do, make sure the staples are the right size for your particular staple gun. To find out what size staples to use, refer to your staple gun’s manual. Once you’ve purchased the right size staples, carefully load them into your staple gun following the instructions in your manual. If needed, use tweezers, needle-nose pliers, or an awl to place the staples into the gun.

But if your staple gun uses a long strip of staples, you may need to replace the entire strip rather than individual staples. Refer to the manual for your specific staple gun model for instructions on how to properly load new staples.

5. Adjust the Tension Knob

The tension knob may need to be adjusted if the staple gun is not firing correctly. Try turning the knob clockwise or counterclockwise until the problem is resolved. If the tension knob does not adjust easily, this may be due to a faulty or broken part inside the gun. In this case, you should take the staple gun to a professional for repair. Make sure that you use the correct parts when replacing or repairing any components of your staple gun.

 Tension Knob May Need to Be Adjusted

It’s important to use caution when adjusting the tension knob, as too much pressure or force could cause damage to other parts of the staple gun. You may also need to refer to the manual for specific instructions on how to properly adjust the tension knob for your particular staple gun model.

6. Lubricate the Gun

If the staple gun is dry, it could be causing it to misfire. Try lubricating the gun with light oil or WD-40 to see if that fixes the problem. If it does not, the spring may need to be replaced.  Also, check the air vents (if it is an electric model) to make sure they are not blocked. While you are at it, check the staples to make sure they are not bent or worn. However, if the spring is no longer functioning correctly, it will have to be replaced.

You can use a general-purpose lubricant or gun oil to lubricate your staple gun. Be sure to refer to the manual for specific instructions on where and how to apply the lubricant. It’s also important not to use too much lubricant, as this can cause the staple gun to malfunction or get clogged.

7. Check for Jams

Another potential cause of a misfiring staple gun is a jam in the mechanism. Be sure to check for any jams and clear them before troubleshooting any further. To check for jams, open up the staple gun and look through the feeder tubes. Look for any bent staples, pieces of fabric, or other foreign objects that can cause a jam. Remove the foreign object and close up the staple gun before trying to fire it again. If, after clearing out jams, the gun still misfires, move on to the next step.

However, if the jam occurs more frequently, this could be a sign of a bigger issue with the staple gun. In this case, you should take the staple gun to a professional for repair.

8. Check the Spring Lever

The spring lever is responsible for releasing the staples when the trigger is pulled. If it is not working correctly, it could be causing misfirings. Try adjusting or replacing the spring lever to see if that fixes the problem. If the spring lever is in good condition, try replacing the staples with a different size or type of staple. Make sure the staples are the correct size and type for your stapler.

Otherwise, if the spring lever is damaged or worn, it will need to be replaced. Refer to the manual for your specific staple gun model for instructions on how to properly replace this component.

9. Replace the Spring Lever Assembly

If all else fails, you may need to replace the entire spring lever assembly in order to get your staple gun back up and running again.  This is a more complicated repair and should only be attempted by experienced users. Be sure to completely disassemble your staple gun, as well as the new lever assembly, to ensure that all pieces are properly aligned. A misalignment could cause the gun to jam or not shoot staples correctly.

Completely Disassemble Your Staple Gun

Once everything is correctly in place, put the gun back together and test it out to make sure the problem has been solved. With any luck, your staple gun should be as good as new! However, if the issue persists, it may be time to retire your old staple gun and invest in a new one.

10. Contact a Professional Repair Service

If you are unable to fix your staple gun yourself, consider contacting a professional repair service for assistance with troubleshooting and repairs. They should be able to help you restore your staple gun so you can get back to using it again.

Fixing your staple gun doesn’t have to be a complicated process. Following the steps above should help you troubleshoot and fix any issues with your stapler quickly so you can get back to using it as soon as possible. Having trouble with your staple gun?

Do You Need to Hire Professional Support?

While it is possible to fix most issues with your staple gun on your own, there are some situations where it may be necessary to hire professional support. If you are not experienced in repairing tools or if the issue seems more complex than what can be fixed by following these steps, it may be best to seek help from a professional repair service.

Additionally, if your staple gun is still under warranty, it may be best to contact the manufacturer for assistance with repairs or replacements. Attempting to fix the issue yourself could potentially void the warranty and leave you without recourse if something goes wrong.

It’s always better to be safe than sorry when it comes to repairing tools, so if you are uncertain about fixing a problem with your staple gun, it may be best to seek professional support. This will ensure that the issue is properly diagnosed and fixed without causing further damage or complications.

How Much Could It Cost?

The cost of repairing a staple gun will vary depending on the type and severity of the issue. If it is a simple fix, such as replacing a worn spring or clearing a jam, the cost may be minimal. However, if more complicated repairs or replacements are needed, it could cost significantly more.

In general, DIY repairs will likely be less costly than hiring professional support. However, it’s important to consider the potential risk of causing further damage if you are not experienced in repairing tools. If in doubt, it may be best to leave the repairs to a professional.

You should also consider the cost of replacing your staple gun versus repairing it. If the issue is more severe and will require costly repairs, it may be more economical to simply replace the stapler altogether.

Things to Consider When Fixing a Staple Gun Spring:

1. Disassemble the Staple Gun and Inspect the Spring

If it looks bent or otherwise damaged, you may need to buy a new spring to replace it. Otherwise, you may be able to repair the existing spring.

2. If Repair Is Necessary, Use Pliers to Bend the Spring Back into Shape

You should proceed slowly and carefully in order to avoid damaging the spring further or even breaking it entirely. Check your progress frequently as you work.

3. Reassemble the Staple Gun and Test It Out

Test out your newly fixed staple gun spring by stapling some paper or other material to make sure it works properly. You may need to fine-tune the tension of the spring after reassembling it, so be prepared for that possibility as well. An error occurred during generation. Please try again or contact support if it continues.
