Milwaukee Paddle Trigger
Model Number: 31-92-0255
The Milwaukee 31-92-0255 is a genuine OEM Paddle Trigger for the 6147-30 4.5 in. Compact Angle Grinder with Paddle Switch with lock-on. This is the molded plastic paddle the operator squeezes to run the grinder: pressing the paddle pivots it against the on-off switch to power the tool, and releasing it lets the paddle return and shut the grinder off. It works together with the paddle trigger spring, which returns the paddle to the off position, and the paddle linkage, which transfers the motion to the switch. Milwaukee lists this part specifically as the Paddle Trigger, and it is a distinct part from the grinder's lock-on button, so if your grinder will not power on or the paddle is cracked, snapped, or no longer springs back, this is the part you need. Because the paddle sits exposed on the underside of the grinder body and takes the squeeze of every trigger pull, it is a common wear and impact part that fails from drops and heavy daily use. Replacing it with the correct genuine Milwaukee OEM paddle restores the exact pivot geometry needed to actuate the switch reliably, which a mismatched aftermarket paddle cannot be counted on to do.
Because Milwaukee Tool specifies replacement parts by both catalog number and serial number, always verify your tool's serial number against the official Milwaukee service parts diagram before placing your order, since running production changes can alter part compatibility within the same catalog number. This paddle trigger is documented at Figure 32 on bulletin 54-38-2231 for the 6147-30 with serial number D05B, and it is referenced on additional Milwaukee compact angle grinders, so confirm your catalog and serial number using Milwaukee's online parts lookup before ordering. Note that the paddle trigger spring at Figure 33 and the paddle linkage at Figure 34 are not carried as individual service numbers and are instead supplied together through the 14-46-6100 Paddle Linkage/Spring Service Kit at Figure 60, which is sold separately and is the part to order if the spring or linkage is also worn. Do not confuse this trigger with the grinder's lock components: the Lock-On Button is a separate part ordered as 42-42-0495 at Figure 36, and the Lock Button Spring is ordered as 40-50-1155 at Figure 35. A set of pliers may be needed to remove a broken paddle during installation.
