Difficult driving

Pins that jam or require excessive force to drive may be dull/worn out.

Inconsistent driving

Pins not driving fully or at uneven depths could indicate dull points.

Missing pins

Check inside stapler body for any loose pins after each use.

Pin breakage

Broken pins left inside material means it’s time for new ones.

Loose pins fall out

Properly formed pins should stay snugly fixed in stapler head.

Staples don’t close fully

Dull pins can’t clench staple ends tightly together.
