13. Timing - Adjusting Loop Lift and Needle Distance
Helpful notes before proceeding;
Note 1: Some hooks are tighter than others on the
hook-shaft. You may be tempted to pry on the hook
mechanism. If you pry on the hook it may become
damaged, irreparable and unusable.
Note 2: 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 3: When the hook screws have been loosened,
the adjustments of the loop lift and needle distance
are possible since the hook can be moved radially as
well as axially.
Note 4: If needle height is not set roughly close first,
it will not be possible to set needle distance correctly
because needle distance is set so the hook point lightly
brushes inside the needle scarf.
Adjusting Loop Lift and Needle Distance:
1. If still in place from the check, remove the clamp.
Make sure the basket is rotated down.
2. Loosen the two screws on the hook base. (2 mm
handle hex tool)
Replace the clamp and reset with
the 2.2 feeler gauge as described in Section 11:
Timing - Checking Loop Lift and Needle Distance,
making sure to turn the hand wheel in the direction
of motion.
3. 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
13.1 above.
