First, turn the action mode changing ring so that the arrow on
the tool body points to the
ring to the proper torque level for your work. Then proceed as
follows.
Place the point of the driver bit in the screw head and apply
pressure to the tool. Start the tool slowly and then increase
the speed gradually. Release the switch trigger as soon as
the clutch cuts in.
NOTE:
• Make sure that the driver bit is inserted straight in the
screw head, or the screw and/or bit may be damaged.
• When driving wood screws, predrill pilot holes to make
driving easier and to prevent splitting of the workpiece.
See the chart.

Drilling operation

CAUTION:
• Pressing excessively on the tool will not speed up the
drilling. In fact, this excessive pressure will only serve to
damage the tip of your bit, decrease the tool
performance and shorten the service life of the tool.
• There is a tremendous force exerted on the tool/bit at the
time of hole break through. Hold the tool firmly and exert
care when the bit begins to break through the workpiece.
