Hitachi 6688231 Throttle Trigger Replacement Part

The Hitachi 6688231 Throttle Trigger is a genuine OEM replacement part designed to restore proper speed control and trigger response to Hitachi power tools. When a throttle trigger wears out, cracks, or becomes unresponsive, it can compromise both the performance and safety of your tool. This factory-spec replacement is manufactured to the same tolerances and material standards as the original, ensuring a precise fit and reliable operation once installed.

The part is broadly compatible with Hitachi power tools used across woodworking, metalworking, concrete drilling and cutting, and outdoor power equipment applications. As with any replacement part, it is important to verify that part number 6688231 matches your specific tool model by consulting the tool's parts list or service manual. Since Hitachi Power Tools has rebranded to Metabo HPT, this part may also appear under updated branding, but the part number and specifications remain the same. For tool owners who prefer OEM components over aftermarket alternatives, this throttle trigger provides a straightforward path to getting a worn or damaged tool back into reliable service.
