How to Unjam a Bostitch Stapler

Bostitch is owned by tools-giant Stanley. Construction staplers include 16-gauge medium. The staples for it are either ½ inch in width or 1 inch in width. There is a 17-gauge stapler and its staples have a 7/16-inch narrow crown. Applications include box frame staplers, lathing staplers, which can be used for light-duty structural assembly, and sheathing staplers, which are also used for siding. They also make desk staplers and heavy-duty manual staplers. Sometimes the staplers will jam, despite being called jam-free.

Things You'll Need

• Punch
• Hammer

Instructions

1. Disconnect the construction stapler from the air supply. Use a hammer and punch to do this. Ignore this step for nonconstruction staplers.

2. Push the driver upwards and past the jammed staple. Do this by putting the punch at the tip of the driver, which you should see coming out of the nose. In the case of a desk stapler, or manual stapler, remove the pusher or follower block, and remove the remaining staples. Insert a pencil behind where the staples come out under the magazine and press down a few times with the pencil.

3. Tap the hammer against the punch and the jam should clear. Only hit the driver. It's the only moving part there.

Tips & Warnings

• Don't hit the jammed staple in a construction stapler; it can make the problem worse.
