The standard for adjusting the clearance between the needle and the blade point of the shuttle
Use a standard Schmetz 794-Nm230 needle.
(1) Adjust the clearance (NO. ) between the convex section of needle (NO. ) and driver
(NO. ) to 0.
(2) Align the needle center with the blade point of shuttle (NO. ) and press the NO. section of
the needle against the driver (NO. ).
(3) Adjust the clearance NO. section to a minimum, with the needle (NO. ) pressed against
the driver (NO. ), making sure that the needle (NO. ) does not contact the blade point of
the shuttle (NO. ).
By this adjustment the needle-to-shuttle blade point clearance will be 0.25~0.35 mm.
