I recently bought a 'Bosch PSB 1800 LI-2 Cordless Lithium-Ion Hammer Drill Driver' from amazon and it sparks and produces a quick flame inside the ventilated area at the back after pulling the trigger. Is this normal? Having googled it, it appears opinion is divided on this?
I emailed Bosch a couple of weeks ago and haven't received a response.
Any input would be appreciated.
