7 b. . Adjusting the Presser Bar Height
Version B (Newer Machines)
(Tools required: 3 mm handle allen, 0. 5mm feeler gauge)
Check:
Figure 13.1
When the needle bar is in its lowest position, the
sewing foot should be no higher than 0.5mm above the
needle plate as shown in Figure 7.3. It is permissible
for the sewing foot ring to lightly touch the needle plate.
Note: the factory default on the sewing foot: screwed
into the presser bar 7 revolutions. To check the foot,
without removing it, there should be about 13-15
threads of the foot exposed below the hopping foot jam
nut.
It is important to check this before resetting the
presser bar height in case the end user has changed the
foot height. Improper setting of the presser bar height
and foot height can cause stitch problems including
skipped stitches.
Figure 7.3
If a correction is necessary:
•
Turn the handwheel until the needle bar is at its
lowest position.
•
Place the (
0.5mm feeler gauge)
under the
hopping foot. Figure 7.3
•
Loosen screw C through the machine front cover
(3mm allen driver)
Figure 7.4
•
Wiggle the presser bar up or down to the desired
position.
•
Tighten screws C. Figure 7.4 – push down lightly
on the tool blade towards table while tightening.
7 c. Adjusting the Presser Foot (Sewing Foot)
The HQ-Sixteen features the “
KinetiQuilt”
hopping
mechanism, allowing the sewing foot to move (hop) up,
down, and dwell on the fabric when the needle is in the
fabric. This allows fabric to move through the machine
similar to a normal sewing machine with a feed dog.
The dwell time allows for a longer hesitation of the foot
on the fabric and completion of the stitch cycle. The
results are better tension, less needle breakage, and
increased hook life.
If a correction is necessary:
•
Install the loop lift clamp onto the right angle bend of
the sewing foot as shown in Figure 7.5. While
holding the clamp and foot, loosen the jam nut.
Screw the foot shaft to the desired height. Tighten
the jam nut.
(clamp, 8mm open end wrench)
Note: Under NO circumstance loosen or tighten the jam
nut without HOLDING the sewing foot as indicated.
