Thermal Protection

Milwaukee’s REDLINK™ Intelligence software communicates between the tool and the battery to improve both motor and battery performance, increasing efficiency, productivity, run-time and safety. The system detects overheating and shuts the tool down to protect against excessive heat until safe to use again.

Its important to note that this feature protects your investment and lets you know your pushing the tool too hard.

Run Time Results

Run-time Results

We installed 1198 brads and experienced 16 thermal shutdowns. One impressive result was that not one jamb was encountered during this testing or later during our finish carpentry work on subsequent job site usage.

From the first fastener installed to the last, all of the fasteners were installed consistently at the same depth setting. The only exceptions were when an operators lifted the nailer off the surface while fastening. [operator error]

Brad magazine

Nail Capacity

The Milwaukee FUEL 18 Gauge Brad Nailer 2740-21CT installs 18 gauge fasteners from 5/8” to 2-1/8” brads, the magazine is capable of holding 110 brads.

Loading the nails is straight forward and the nailer will stop firing [dry fire lock-out] there are 4 to 5 brads left. Fastener dry fire lock-out is indicated when the brad nailers work piece contact will not compress. Clearing jams is simple though unlatching the “lamb latch,” clip but as mentioned earlier, we fired approximately 1800 brads while testing this unit and never encountered a fastener jamb.
