This repair part is made by the Original Equipment Manufacturer (OEM) to return your equipment to peak performance levels after normal use. When installing it, remember to do so in a well lit and ventilated space, while taking proper safety precautions like eye protection and chemical-resistant gloves as appropriate. Using only Genuine OEM parts, the same that would be used by an Authorized Dealer performing a warranty repair, will ensure the optimal performance and prolong the life of your equipment.
