CORD TRIM ADJUSTMENTS
Shear Cross-Over
Knife actuator
G
is adjusted to run parallel to the edge of the clamp plate. The shears are activated when
the race starts to turn back to the home position. As the race turns the paddle, located on the rear of the
race, engages the knife actuator which causes the shears to cross-over. Having the actuator parallel brings
the cutting edges together without causing a bind in the machine. If the shears are forced to cross-over
more than required (edges crossing over until they meet at the point), the machine will bind and damage
key parts, including the main cam. Below is an example of the shears when they are in the correct parallel
position.
To adjust, loosen nut
H
and rotate actuator to correct position. Once the correct position has been
obtained, re-tighten nut
H
.
NOTE:
The correct buttonhole lengths must be maintained. Long sewing of the buttonhole will cause the
needle to strike the shears, causing damage to both the needle bar and shears.
