2) Every tine the thread trimmer actuates, the machine proceeds to the subsequent pattern which has been
selected. (The step which is being executed is shown in reverse video during execution.)
Cau tion If the thread trimmer actuates before completion of a pattern, the machine will proceed to
the subsequent program.
5-3. How to use the bobbin thread counter
The machine detects the number of stitches. The preset value on the bobbin thread counter is subtracted in
accordance with the number of stitches detected. (Every time the detector detects 10 stitches, 1 is subtracted
from the preset value on the bobbin thread counter.) When the value on the counter becomes a minus value as
( ........ → 1 → 0 → –1), the buzzer (peeps three times) and the pop-up display inform that the time to change the
bobbin thread has come.
When IP-100 is mounted on LH-4168 and LH-4188, the bobbin thread counters are separately installed for lefthand bobbin and right-hand bobbin . However, the display on the panel is either one of them, and the
display can be changed with switch 1.

The bobbin thread counter cannot be
reset during sewing. In this case, make
the thread trimmer actuate once.
2) Set an initial value using counter value setting switches
笳 and 笘.

* Actually, the bobbin thread counter is affected by the material thickness and the sewing speed. So, adjust the
initial value of the bobbin thread counter in accordance with the operating conditions.
3) Once the initial value is specified, start the sewing machine.
4) When a minus value is shown on the counter, the buzzer peeps three times and the pop-up display appears,
replace the bobbin thread.
Bobbin thread replacement warning pop-up
5) After the bobbin thread has been properly replaced, press counter reset switch 笆 to return the value on the
bobbin thread counter to the initial value. Now, re-start the sewing machine.
6) If the remaining amount of bobbin thread is excessive or the bobbin thread runs out before the bobbin thread
counter indicates a minus value, adjust the initial value appropriately using counter value setting switches 笳
and 笘.
If the remaining amount of bobbin thread is excessive ..... Increase the initial value using the “+” switch.
If the remaining amount of bobbin thread is insufficient .... Decrease the initial value using “–” switch.

the pedal until the stop position of the current step.
6) When re-sewing switch 1 is turned ON again at the stop
position, the step is changed over to the subsequent step,
and the corner pattern can be continued.
* When thread breakage or the like occurs during the free
stitching operation d using re-sewing switch 1, set the
pedal to neutral and perform thread trimming operation by
depressing the back part of the pedal. Perform threading and
slightly return the material edge. Then press re-sewing
switch 1 and the free stitching can be continued. After this,
the operation is the same as steps 5) and 6).
When returning to the first step without
using re-sewing switch 1, the step
Cau tion display returns to “1” and the sewing can
be performed from the first by
depressing the back part of the pedal to
perform thread trimming.

5-6. Needle up/down compensation switch
Every time needle up/down compensation switch 笊 is
pressed, the needle goes up when it is in its lowest position
or comes down when it is in its highest position. This
compensates the stitch by a half of the predetermined stitch
length.
Note, however, that the machine does not run continuously
at a low speed even if you keep the switch held pressed.
Also, note that the needle up/down compensation switch is
inoperative after turning the handwheel by hand.
Thread trimming is operative only at the time of stitch
compensation after depressing the front part of the pedal once.

completes the automatic reverse stitching (for end).)
5-9. One-shot automatic stitching switch
• This switch is used, in the step pattern , or in the process where the material edge sensor is specified, to make
the sewing machine automatically perform sewing at the specified speed until the end of the process is
reached only by driving the sewing machine once.
5-10. Thread trimming prohibition switch
• This switch is used to temporarily make the thread trimming function inoperative.
The other performance of sewing machine is not affected by this switch.
(If the automatic reverse stitching (for end) is specified, the sewing machine will perform the automatic reverse
stitching at the end of sewing.)
• If the automatic thread trimming switch
and the thread trimming prohibition switch
the machine will not perform thread trimming but stop with its needle up.
are both specified,
5-11. Key lock
• In order to prevent the specified data on the number of stitches or the processes (A, B, C and D, or step
information) from changing by mistake, the setting switch can be locked. (Even with the setting key locked,
the pattern to be sewn and the value on the bobbin thread counter can be changed.)
• For the setting procedure, refer to 5-13 Setting for functions and set function No. 17, Key lock function (key
