Bosch PSB 1800 LI-2 Drill sparks and stops when on full power
Hi, I bought a Bosch PSB 1800 LI-2 Cordless Combi Drill a year ago, a few weeks after I bought it when I fully pressed the trigger the motor would spark and the drill would stop. I lost the receipt so couldn’t take it back. Yesterday I bought the same drill (without the batteries) from Amazon, it does exactly the same, fully depress the trigger the motor sparks and the drill stops. The drill works fine IF I don’t fully depress the trigger. The batteries are fully charged. As this is happening in both drills is it supposed to happen?!!
