Adjusting the Hook Timing
1. Clean any thread debris or lint from the hook
area with compressed air.
2. Loosen the three screws at the rear of the
hook. This will permit advancing or retarding
the hook.
3. Remove Back Center Cover.
4. Rotate main motor pulley to where the
indicator points to 24 degrees. The point of
the hook should be directly behind the needle.
If not, the hook needs to be adjusted
accordingly.
5. Check the hook-to-needle clearance. There should be
approximately one half to one thread-width clearance
between the hook point and the back of the needle.
Improper adjustment would cause the hook point to
miss the small loop and create a skipped stitch.
6. When the correct position has been attained, tighten
the three screws on the hook.
7. Replace the throat plate.
8. Using a lettering or a digitizing system, create an
H O X
test as follows:
• Using a block alphabet, program “H O X” in capital letters, 20mm high, into the
machine. These letters are used because they encompass all the various directions of
the pantograph.
• Sew the letters.
•
Check for any irregularities in the sewing. If the machine is not properly timed, it
will result in skipped stitches.
Position Finger Adjustment
The adjustable position finger is mounted in front of the hook assembly to secure the hook
basket in place and balance the bobbin thread down the center of the embroidery. The
position finger is adjustable in two directions, left to right, and front to back. Adjustment of
the position finger is required if the bobbin thread is running left or right of center, or if the
position finger was removed during the replacement of the hook assembly.
Sometimes the finger moves out of adjustment. When correct, the position finger nose, the
protruding part, lines up centered with the hook assembly shaft.
