Changing the maximum feed amount
If the feed dog has been replaced by one that does not match the feed amount that is currently being used, the feed dog may
touch the needle plate if the stitch length dial or condense dial are mistakenly set to settings that are larger than the maximum
feed amount for the feed dog, and this could cause problems such as damage or noise.
In order to prevent dial setting errors such as this, change the maximum feed amount setting for the sewing machine to match
the maximum feed amount for the feed dog.

5-2-4. Setting the zigzag base line position
The zigzag base line is the “center” of the zigzag stitch, or in other words, it is like a center line drawn through the sewing
pattern.
By moving the zigzag base line position, you can move the sewing pattern to the left and right within the maximum range for
the pattern width.

The currently-set zigzag base line
position will appear in the main
display (1).
(For example, [ L2.0] indicates
that the pattern position is 2.0 mm
to the left, and [ r2.0] indicates
that the pattern position is 2.0 mm
to the right.)

NOTE:
• The zigzag base line position cannot be changed if the indicator is not illuminated, even when the zigzag base line position
is being displayed in the main display . When changing the zigzag base line position, press the zigzag width/zigzag base
line position key so that the indicator is illuminated, and then change the setting.
• If the needle bar is at the needle up stop position, the needle bar will move to the sewing start position when the zigzag
base line position is changed.
If the needle bar is not at the needle up stop position, the needle bar will move to the sewing start position after it next
moves to the needle up stop position.
Relationship between zigzag base line position and zigzag width (when the maximum zigzag width is 8 mm)
By way of example, consider a sewing pattern (Figure A) with a zigzag base line position set to [ 0] and a zigzagwidth set
to [4.0 ]. If the zigzag base line position is set to [ L2.0], the pattern will be moved over toward the left edge (Figure B).
The sewing pattern cannot move any further to the left even if a larger setting is made. (Even if the zigzag base line position is
set to [
L3.0], the sewing pattern position will be the same as if the setting had been [
L2.0]. (Figure C.)
However, in this case, if the zigzag width is set to [2.0
], a sewing pattern such as that shown in Figure D will be produced.

Depress the treadle to start sewing the start backtack stitches.
After this, stitches will be sewn at the pitch set by the stitch length dial (1).
NOTE:
• The sewing machine will continue operating until the set number of start backtack
stitches has been sewn, even if the treadle is returned to the neutral position. (The
sewing machine operates at a speed of 1,200 rpm when sewing start backtack
stitches.)
• Stop in the needle up stop position at that point. (For the 8560A, the thread will be
trimmed and then the needle will stop in the needle up stop position.) (If the zigzag
stop position has been set, the needle will stop in the set position.)

CAUTION
Attach all safety devices before using the sewing machine. If the machine is used without these devices attached,
injury may result.
Turn off the power switch at the following times.
The machine may operate if the treadle is depressed by mistake, which could result in injury.
• When threading the needle
• When replacing the bobbin and needle
• When not using the machine and when leaving the machine unattended
Do not touch any of the moving parts or press any objects against the machine while sewing, as this may result in
personal injury or damage to the machine.
Never touch the knife on the face plate when opening the thread takeup guard cover at times such as when taking
up slack in the thread, otherwise injury may result.
Use both hands to hold the machine head when tilting it back or returning it to its original position. If only one hand
is used, the weight of the machine head may cause your hand to slip, and your hand may get caught.
1. Press the ON power switch.
(Refer to page 12.)
2. Use the operation panel to make the necessary settings
such as sewing pattern and zigzag width.
(Refer to page 21.)
3. Set the stitch length using the stitch length dial.
(Refer to page 19.)
4. Depress the treadle to start sewing.
