Husqvarna 525LST 25.4 cc 17 in Gas String Trimmer HIGH VIBRATION Error Fix: Excessive Vibration

The trimmer vibrates excessively during operation — worn clutch drum bearings, a damaged drive shaft bearing, or loose hardware cause abnormal vibration; the 525LST has a straight shaft with a flex cable drive; a worn bearing where the shaft enters the trimmer head housing causes wobble and vibration; also check the trimmer head for balance — an uneven line load creates vibration at high RPM
