Proper Machine Setup: Upper Thread
Upper Tensioner
Thread only makes ½ turn
– make sure it passes to
the left between the 2
metal discs.
Lower Tensioner
Thread makes 1 full turn
clockwise around the base
of the knob – make sure it
runs in the V-shaped
groove of the spoked
wheel.
Thread Break Sensor
Thread this like the upper
tensioner – ½ turn to the left.
Make sure the thread falls in the
groove as shown.
UPPER THREAD – complete route through moving head
-
Proper Thread Routing:
All threads
must
be routed
correctly at all points along the path through the sewing
head.
-
Practice good thread “Discipline”:
After threading
all needles, ensure there is no slack anywhere along
the thread path. Make sure to:
-
Pull all threads
– to ensure thread feeds
smoothly and turns the break sensor, and all
slack is removed from around thread cones
-
“Dock” all thread ends
from each needle onto
the thread-holding spring. Prevents thread from
coming loose and catching where not desired.
Take-Up Levers
Thread makes 1 full turn clockwise
around the base of the knob – make
sure it runs in the V-shaped groove of
the spoked wheel.
