the keyless chuck on my BOSCH PSB 600 RES doesnt lock?
the keyless chuck on my BOSCH PSB 600 RES doesnt lock or open or engage when i press and hold the button also the screws holding the drill body together have unusual heads wich normal screwdrivers could not engage, would i have to buy a special screwdriver to open these. thanks, jim.
