9. Adjustment of the Loop Lift and Needle Distance – Continued
Note:
If needle height is not set roughly close fi rst, it will
not be possible to set needle distance correctly.
If a correction is needed:
If still in place from the check, remove the clamp. The
basket must be rotated down in order to make setting the
needle distance properly possible.
See previous page for
information and pictures on rotating the basket down
.
Note:
Once the basket has been turned down it must be
held while turning the hand wheel to prevent it from
turning and colliding with the needle.
Note:
When the hook screws have been loosened, the ad-
justments of the loop lift and needle distance are possible
since the hook can be moved radially as well as axially.
Note:
Some hooks are tighter than others on the hook-
shaft. You may be tempted to pry on the hook mecha-
nism. If you pry on the hook it may become damaged,
irreparable and unusable.
• Loosen the two screws on the hook base.
(2 mm handle
Allen) (Figure 9.10)
Replace the clamp and reset with the
2.2 feeler gauge as described on page 28, making sure to
turn the hand wheel in the direction of motion.
• Set the hook to the correct positions by sliding the hook
axially (needle distance) on its shaft, as well as radially
(loop lift), setting the hook point relative to the needle, as
described on the next page. For radial position of loop lift
see
Figure 9.8.
