a. Enter 201 in the Set Position box, then click the Go to Position button. Check the number dis-

b. This number may not be the exact number you entered. If it is not, use the microstep forward

Arrow button) to increase the z position by tenths of degrees until the correct hook timing
position (201.5) is displayed in the Current Z Position box.
12. Adjust the hook to needle gap with a shortened 1.5mm bent Allen key to access the adjustment
set screw (highlighted in green in the image below). As you adjust the screw, the hook will move
gradually forward or backwards. Adjust until the gap between the needle and hook point is
0.1mm (.004”).
