Pull the trigger and the drill spins; release the trigger and the drill spins. I can see that being a recall. Bosch advises “Stop using immediately” if you own their hammer drill model 1191VSRK. Even if yours hasn’t malfunctioned yet, you might consider contacting Bosch — and if it starts running as soon as you plug it in, you should absolutely call them.
The malfunction seems to appear only in the serial number series starting with “7” — 7XXXXXXXX — and the K on the end of the model number means the drills were included in kits. Check out the release on the Bosch site if you might be affected.
