OPERATING MANUAL OPERATION STEM

PROCEDURE
• Turn off the power. With power on, the manual operation stem cannot be operated.
• Shape of the manual operation stem is 8 mm square. Use an adequate wrench.
• Moving the output stem to the direction of full-open, turn the manual operation stem to the right viewing from the top of
the cover.
• Rotate the manual operation stem while visually checking the indicator (O-S) and the pointer on the top of the cover, and
confirming the direction, and the angle (90° to 0°).
• A mechanical stopper is provided inside the machinery to prevent excessive movement when using the manual operation
stem. Continuing turning the manual operation stem strongly even though it has hit the mechanical stopper, the inside
the machinery may cause malfunction.
