To loosen top thread tension
To loosen the top tension, turn the top thread tension
knob (see page 10, Figure 2, #5) counter-clockwise.
N OTE : Before adjusting the top tension, remember to floss or pull the top thread up into the tension discs
otherwise the top thread will float outside the discs providing little or no top tension. This could cause
significant tension or nesting problems on the bottom side of the quilt. If the top tension is too loose
(causing loops of thread on the underside of the quilt) and no amount of tightening the top thread tension
knob seems to affect it, there’s a good chance that the thread is riding on the outside of the tension discs
and has not been “flossed” so the thread is lying between the discs properly.
Maintenance
NOTE : Turn off the machine and unplug the power cord when performing maintenance on the machine.
Cleaning and Lubricating the Machine
Use only good quality light sewing machine oil in the Baby Lock Tiara III. Internal oiling is not necessary on the Baby
Lock Tiara III except when the machine is taken to your authorized Baby Lock retailer for routine maintenance and
cleaning. The hook assembly, however, needs regular lubricating. Failure to keep the hook assembly lubricated can
cause severe damage to the machine.
To lubricate, turn off and unplug the machine. Remove
the bobbin and bobbin case before oiling. Clean around
the hook assembly with a soft brush to remove lint. Put
a very small drop of oil on the hook in the region where
the bobbin basket assembly and the rotating hook meet
(see Figure 20). The bobbin basket is the portion of
the hook that the bobbin case snaps into. The bobbin
basket remains stationary while the hook rotates around
the basket. The oil lubricates the region where these
two components interlock. A drop of oil in the region
indicated will work its way back into the interlocking
area of the hook and bobbin basket.
