"DRILL" is foot-switch.\nPress it to move drill down,\nrelease to return it to start position.\nDouble-click turns drill motor on/off.\n
Text Notes 6350 7250 0 60 ~ 0
Two buttons on tray have following functionality:\nBTN1 - setup zero point (move slowly + set coordinate\n to 0 after footswitch released); next pressing returns\n device to normal state;\nBTN2 - switch between regulation of drill speed/stepper speed;\nBTN1+BTN2 (simultaneously) - move tray up/down.\n\n"volume" varistor allows to regulate motor speed.\nDefault is max drill speed, varistor regulates stepper speed.
