3. If oil is mistakenly swallowed, diarrhea or vomitting may occur. Put oil in a place where children cannot reach.
Fill the oil tank with oil for hook lubrication before operating the sewing machine.
1) Remove oil hole cap 1 and ll the oil tank with JUKI New Defrix Oil No. 1 using the oiler supplied with the machine.
2) Fill the oil tank with oil up to the place where the top of oil amount indicating rod 3 aligns with the upper engraved line of oil amount indicating window 2. If the oil is lled excessively, it will leak from the air vent hole in the oil tank or proper lubrication will be not performed. So, be careful.
3) When you operate the sewing machine, rell oil if
the top end of oil amount indicating rod 3 comes down to the lower engraved marker line of oil amount indicating window 2.

Standard delivery level of the key lock is “1”. When the level of the key lock is the case other than “0”, be sure to change the level to “0” to perform the operation below.
The continuous stitching is a function created by supposing the case where the different patterns are con­nected and sewn, or the case where the sewing is performed beyond max. number of stitches per pattern, 500 stitches. Therefore, the connected patterns are recognized as one pattern. Continuous stitching can sew the different zigzag patterns in combination.
Changeover of the respective patterns can be set with the number of stitches. Continuous stitching can combine as many as 20 steps and 500 stitches per step can be set. In addition, up to 10 patterns can be registered. To perform the continuous stitching, it is necessary to register in advance the pattern to be used in each step.

(3) Detailed explanation of selection of functions

Selection of the soft-start function (Function setting No.1 N-SOFT)
1
The needle thread may fail to interlace with the bobbin thread at the start of sewing when the stitching
pitch (stitch length) is small or a thick needle is used. To solve such problem, this function (called “soft-start”)
is used to limit the sewing speed, thereby assuring successful formation of the starting stitches.
0 : The function is not selected.
1 to 9 : The number of stitches to be sewn under the soft-start mode.
The sewing speed limited by the soft-start function can be changed. (Function setting No.37 S-SOFT)
Data setting range
150 to 5,500 sti/min <50 sti/min>
Flicker reducing function (Function setting No.5 T-ACC)
2
The function reduces ickering of the hand lamp at the start of sewing. The higher the set value increases,
the more effective the function will work.
Setting range
0 to 8
0 : Flicker reducing function does not work.
to
8 : Flickering is effectively reduced.
The more effective the icker reducing function works (the more the set value is made), the lower the start-up speed of the sewing machine will become.
Setting of the needle bar stop position when the sewing machine stops (Function setting No.10 NPS)
3
The position of the needle bar when the pedal is in its neutral position is specied.
0 : Down The needle bar stops in the lowest position of its stroke.
1 : Up The needle bar stops in the highest position of its stroke.
If the stop position of the needle bar is set to the highest position, the thread trimming action will be taken after the needle bar comes down once to the lowest position.
Sound of click of the key switch mounted on the PSC box (Function setting No.11 SOUND)
4
This function selects whether the sound is effective or ineffective when operating the four key switches
mounted on the PSC box.
0 : off The sound of click is ineffective.
1 : on The sound of click is effective.

Optional switch function selection (Function setting No.12 SW 2) : It is used only when it is com-
5
bined with the machine head provided with the optional switch. (Optional SW kit Part No. : 40003640)
A. In case of the machine with the auxiliary thread take-up lever
Optional SW
B. In case of the machine without the auxiliary thread take-up lever
Optional SW
Functions to be assigned to the optional switch can be selected from the following functions.
0 : No function (Standard setting)
1 : Needle up / down compensating stitching : Every time the switch is pressed, normal feed
stitching by half stitch is performed. (Same operation as that of up/down compensating
stitching switch on the panel.)
2 : No function
3 : No function
4 : Thread trimming function : This function is actuated as the thread trimming switch.
5 : Presser foot lifting function : This function is actuated as the foot lifter switch.
6 : One stitch compensating stitch : Every time the switch is pressed, one stitch stitching opera-
tion is executed.
7 : No function
8 : Pedal neutral presser lifting function selection
Do not set to 2, 3, and 7. If these numbers are set, trouble or accident will be caused.
Neutral automatic presser lifting function (with AK device only) (Function setting No.21 N-NPL)
