Screwdriving operation (Fig. 6)
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 trigger just as

screw may strip out the hole or the screw and/or bit may
be damaged.
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.
