Loosen Top Thread Tension
To loosen the tension, turn the top thread tension knob
(page 10, Figure 1, #5) counter-clockwise.
NOTE: Before adjusting the top tension, remember
to floss or pull the top thread up into the tension discs
otherwise it 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 is not “flossed” between them.
NOTE: Turn off the machine and remove the power cord
when performing maintenance on the machine.
Cleaning and Lubricating the Machine
Only use good quality light sewing machine oil in the
Baby Lock Tiara II. Internal oiling is not necessary on the
Baby Lock Tiara II except when the machine is taken to
your authorized Baby Lock retailer for routine mainte-
nance and cleaning. The hook assembly, however, needs
regular lubricating. Failure to keep the hook assembly
lubricated can cause severe damage to the machine.
Maintenance
Figure 18
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 19)). 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 bas-
ket. The oil lubricates the region where these two compo-
nents interlock. A drop of oil in the region indicated will
work its way back into the interlocking area of the hook
and bobbin basket.
The frequency of lubrication depends upon the usage of
the machine. Lubricating is recommended before run-
ning the machine if it has not been used regularly, or
every other bobbin change if used frequently. After oiling,
always stitch through a scrap piece of fabric, as oil may
cling to thread. Over-oiling can cause excess dripping
from the bobbin assembly. Lack of lubricant may be
noticed by a change in the sound of the machine and will
affect stitch quality.
Cleaning the Touch-Screen Display
Use a soft clean cloth dampened with isopropyl alcohol
to gently wipe the display and remove any marks. Never
use any other chemicals to clean your display as they may
adversely affect the touch-screen response and clarity.
