Head Directions
The head can be mounted in four directions. To remove the head,
turn the head by 45° as shown in figures A and B below.
To change the direction of the head, make sure that the
protruding part of the rotating lever engages with the groove of
the plunger. Then turn the head clockwise or counterclockwise to
the desired direction. At that time, make sure that the groove of
the plunger is located under the rotating lever. If the direction of
the head is not set when the plunger is rotated by 45°, the groove
of the plunger presses the rotating lever. The head, plunger, or
the built-in switch may be damaged as a result.
