• Use the reversing switch only after the tool comes to a complete stop. Changing the direction of rotation before the tool stops may damage the tool. • When you operate the tool in counterclockwise rotation, the switch trigger is pulled only halfway and the tool runs at half speed. For counterclockwise rotation, you cannot push in the lock button. This tool has a reversing switch to change the direction of rotation. Move the reversing switch lever to the position (A side) for clockwise rotation or to the position (B side) for counterclockwise rotation. Selecting action mode CAUTION: • Always set the knob fully to your desired mode symbol. If you operate the tool with the knob positioned half-way between the mode symbols, the tool may be damaged. • Do not rotate the action mode changing knob when the tool is running under load. The tool will be damaged. • To avoid rapid wear on the mode change mechanism, be sure that the action mode changing knob is always positively located in one of the three action mode positions.
