While looking from the coupling side of the vacuum pump assembly, rotate the coupling clockwise.

Standard:

Rotates without locking.


NOTICE:
·

As the vacuum pump vane cap may become damaged, do not rotate the coupling counterclockwise.

·

Even if rotation fluctuates between heavy and light, it is not a malfunction unless the coupling locks.
