How To Repair Trimmer When Blades Will Not Stop

Carburetor
If your hedge trimmer blades will not stop turning when the engine is idling, it may mean the carburetor needs to be adjusted. The clutch engages the blades when the engine has reached the correct speed. If the carburetor is adjusted too high, the idle speed may be too fast which will stop the clutch from disengaging, causing the blades to continuously move. Refer to your user manual for information on how to perform this type of adjustment and if it is needed. Keep in mind that EPA law now requires that all carburetor adjustments be made by a trained professional.

Clutch
If the blades on your trimmer will not stop moving when the throttle is released, there may be an issue with the clutch. The clutch is engaged when the crankshaft reaches a certain rotational speed. If the blades are continuously moving, the clutch may be broken. To access the clutch, remove the gearbox and in some cases some of the engine shrouds depending on the model. The clutch sits on beneath the crankshaft. The springs on a clutch can wear over time and the entire component may need to be replaced eventually.
