How to Unjam Blades on an Electric Hedge Trimmer


When your shrubs get a little unruly, an electric hedge trimmer will zip right through the branches and make the shrubs look well-manicured once again. An electric hedge trimmer works with "scissoring action" which means two blades contact each other to shear off what's in between. Occasionally, if a large enough branch gets caught in the blade, the hedge trimmer won't be powerful enough to cut through it and the hedge trimmer will jam. If this happens, rest assured that it is easy to unjam the blades again.

Step 1

Turn the power off to the electric hedge trimmer and unplug the cord from the power outlet.

Step 2

Look over the blades of the hedge trimmer to find the object that is causing the jam. You will most likely notice a branch stuck between two blades.

Step 3

Grasp the end of the lodged branch and pull it back toward the shrub. It should pull out of the hedge trimmer blades.

Step 4

Use a small flat head screwdriver to pry and work out branches that won't pull out by hand.

Step 5

Inspect the blades for damage before you plug in the hedge trimmer and resume trimming your shrubs. Tighten the blades down and adjust them to restore them to their pre-jammed state. There should be adjustment nuts along the length of the hedge trimmer.

Step 6

Wipe down your hedge trimmer blades after each use with a rag to remove loose debris. Lubricate the blades with a penetrating oil to keep them rust free and well-lubricated.

Tips and Warnings

  • Wear gloves when removing the branches from the hedge trimmer. The blades are extremely sharp and can cause serious cuts. Don't twist the blades to remove the stuck branch. The blades could bend or break.
