This tool has a reversing switch to change the direction
of rotation. Depress the reversing switch lever from the A
side for clockwise rotation or from the B side for
counterclockwise rotation.
When the reversing switch lever is in the neutral position,
the switch trigger cannot be pulled.

Always check the direction of rotation before

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 not operating the tool, always set the
reversing switch lever to the neutral position.
