This authentic OEM insulator is located in the pinion gear of your handheld lawn and garden equipment in the blade housing. It acts as a protective barrier, preventing heat transfer and electrical conductivity between various components. To determine if the insulator requires replacement, keep an eye out for significant wear or any signs of abnormal heat buildup while operating your machine. To remove the insulator, consult your user manual for specific instructions on locating and accessing the insulator. Typically, the process involves unthreading the screws on the blade housing to disassemble it and carefully prying the insulator from the pinion gear. Once the new insulator is installed, reassemble your machine by following the steps in reverse order.
