Milwaukee Detent Release Trigger
Model Number: 45-72-0100
The Milwaukee 45-72-0100 is a genuine OEM Detent Release Trigger for the 2739-20 M18 FUEL 12 in. Miter Saw with One-Key. The detent release trigger is the lever at the front of the miter table that the operator presses to disengage the miter detent, releasing the table from its preset positive-stop angles so it can swing freely to a new miter setting. It works alongside the miter lock handle as part of the saw's detent system, and its friction surfaces ride against the detent mechanism, so Milwaukee specifies greasing those surfaces during assembly. A cracked, worn, or broken detent release trigger makes it hard to release the table from its detents or to set an accurate miter angle, which directly affects cut accuracy. Replacing it with the genuine Milwaukee OEM trigger restores the correct lever geometry and clean detent release, where an off-spec part may not actuate the detent or seat correctly.
This detent release trigger is identified as the Detent Release Trigger, Figure 85, on the Milwaukee service parts list for the 2739-20 M18 FUEL 12 in. Miter Saw with One-Key, serial K18A, bulletin 54-40-2810. It is specific to this saw: other Milwaukee miter saws use similar-looking detent release triggers with different part numbers, such as the 45-72-0091 on the 7-1/4 in. 2733-20, so order by the exact part number for your saw rather than by appearance. On the saw it works with the miter detent spring, the miter detent ramp, and the lock rod guide, which are separate items; coat the friction surfaces of the miter lock handle and detent release trigger with grease on reassembly as Milwaukee directs. Because Milwaukee specifies service parts by serial number as well as catalog number, verify your catalog and serial number against the official Milwaukee service parts diagram before ordering, since running production changes can alter part compatibility within the same catalog number.
