Frequently Asked Questions
How does the spring in a stapler work?
The spring creates tension and forces your staple cartridge to the dispensing head. Now when you press the trigger in your manual staple gun or press the lever in your electric or pneumatic staple gun, the hammer gets forced and pushes staples in a specific direction.
Why is my staple gun not firing?
Some critical parts like the spring, rail, and hammer need to be in great shape and assembled perfectly. So, if these parts are worn out or damaged physically, you will not be able to fire staples smoothly.
Why is my staple gun not working?
Your staple gun might not be working because there is a stray staple jamming the spring system. Simply take the spring pusher rod out of the stapler. You will need to unscrew it from the bottom of the stapler. And then use a needle nose plier to extract the stray staple from the inside of your stapler. It will work fine afterward.
What to do if an arrow staple gun is jammed?
If you have a jammed arrow staple gun, the first thing you have to do is take out the bottom of the gun. You can do it by simply pushing the bottom part downwards and it will come out easily. Next, take a screwdriver and a plier to take out the magazine screw.
