7-20. Adjusting the positions of the work clamp plates
Adjust the positions of the work clamp plates (3) so that the throat plate (1) and needle plates (2) do not touch during sewing.
The standard adjustment is when there is a gap of 0.8 mm between the throat plate (1) and the needle plates (2) (when the
cutting space is set to "0").
* Carry out adjustment for both the left and right work clamps. (The adjustment method described below is for the position of
the right-side work clamp plate (3).)
* Carry out adjustment with the work clamp plates (3) installed.
1. Use the parameter settings to set the cutting space to “0”.
(Refer to “5-3-1. Parameter list” in the instruction manual.)
* If you press shortcut key 3 (4), you can then change
the value simply by pressing the / keys (5).
2. Press the TEST key (6) to turn on test mode, and then
start test operation. (Refer to “5-4. Checking the sewing
pattern in test mode” in the instruction manual.)
3. Press and hold the start switch (7) until the feed base
moves to the position where the straight section of the
sewing shape is sewn, and then release the start switch
