If the feeder box becomes sluggish in operation, spray car wax (spray type wax) on its sliding surfaces. 17) This tool can be used to drive at a position 15 mm away from the wall as shown in Fig. CAUTION: Driving at a position closer than 15 mm to the wall or driving with the stopper base in contact with the wall may damage the screw heads and cause wear on the bit. This may also lead to poor fastening of screws and malfunction of the tool. While keeping it in this position, turn the adjusting knob until the bit tip projects approx. If the screw head projects above the surface of the workpiece, turn the adjusting knob in the "A" direction; if the screw head is countersunk, turn the adjusting knob in the "B" direction. 7) Roll up the screw strip in a form of coil counterclockwise and place it inside the magazine. 8) Run the end of the screw strip on the slotted passage starting from above the magazine.
