Ordering by number: this is Y10301070, the Tamco/Toku throttle valve spring. It governs how air reaches the working end of the chipping hammer. Wear on the sealing land is the usual cause of a throttle that leaks with the trigger released.
It is called out in the parts diagram for the THH 1 2 3 4 Chipping Hammer and THA 1 2 3 4 Chipping Hammer, and on 1 other machine. Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
If you need the parts around it, the full diagram library has the full breakdown library, and the Tamco/Toku tool range covers the machines themselves. Denver stock, with same-day shipment on in-stock orders in by 4 PM ET.
