I bought an Amtech 750w hammer drill. How do I insert a drill bit into it? The instruction booklet does not say how to tighten the chuck.

Hi Kothai, our mains hammer drill (V6020) is 710W, not 750W. This drill has a keyed chuck and the chuck key is supplied with the kit. You insert the drill/ screwdriver bit into the chuck and turn it clockwise to close the jaws and then use the chuck key to tighten it fully.
