NOTE: Read this manual thoroughly before sewing on the UNION for the first time!
to Prepare for Sewing:
• Grip the top thread behind the presser foot with the left hand
• Slowly turn the balance wheel counterclockwise one full rotatation.
• The loop should catch the bobbin thread and pull it through the hole in the needle plate
• Lift the foot and pull about 8" (200 mm) of thread (from both top and bottom) through to the back of
the machine
• NOTE: When the take up (UL-135/UL-141) is at it's highest point, the thread is locked. Turn the
balance wheel to lower the take up and release the thread.
• Turn the balance wheel unitl the awl is about to enter the work first. The machine is now ready to sew.
to Commence Sewing:
• Lift the presser foot, place material under the presser foot, then lower presser foot
• Hold the loose thread in the left hand and commence sewing. The machine will pull the top thread on
the first stitch.
• Let the machine do the feeding and do not twist or distort the work. All that is required of the operator
is to guide the work, and the machine will feed properly and sew a consistent, even stitch.
• NOTE: The machine may be in perfect adjustment and still fail to sew satisfactory if the operator is
careless in handling the work, or does not adjust the machine to accommodate for a difference in
work.
to remove the Work:
• Stop the machine when the take up (UL-135/UL-141) is at it's highest point and the thread is locked.
• Turn the balance wheel to lower the take up and release the thread.
• Remove your work and cut your thread with about 8" (200mm) left loose on the machine.
to Lock the Stitch:
• Although it is not always required, it may be necessary to lock your first and last stitch in some
applications. This method prevents the threads from coming apart on the ends, and can be done
manually.
• Simply make the first stitch, stop the machine just before the awl desends into the material, raise the
presser foot, position the work so that the awl will descend next to the first hole of the last stitch made,
and then continue sewing along the desired line.
• The awl should descend just to the side of the first stitch, otherwise, if the awl was set directly over
the thread it would cut through the previous stitch. If done correctly, the two stitches will be uniform so
that they will appear as one.
• It is also possible to lock the stitch by tying the end threads together, melting synthetic thread ends, or
locking the end with a rivet or similar fastener.
