3.加油方法 Lubrication
注 意 CAUTION
在加油未完成前，請勿插上电源。
当誤踩下踏脚板时，縫紉机动作会导致人员受伤。
使用润滑油时，請务必戴好保护眼鏡和保护手套等，以防润滑油落入眼中或沾在皮肤上，这是引起發炎的原
因。
另外，润滑油不能飲用，否则会引起呕吐和腹泻。
将油放在儿童拿不到的地方。
在剪去油罐的油嘴口时，請一定要拿住油嘴的根部。
如果拿住油嘴口，剪刀容易伤到手，成为受伤的原因。
Do not connect the power cord until lubrication has been completed, otherwise the machine may operate if the treadle is
depressed by mistake, which could result in injury.
Be sure to wear protective goggles and gloves when handling the lubricating oil and grease, so that they do not get into your
eyes or onto your skin, otherwise inflammation can result.
Furthermore,do not drink the oil or eat the grease under any circumstances, as they can cause vomiting and diarrhea.
Keep the oil out of the reach of children.
When cutting the nozzle of the oil tank, hold the base of the nozzle securely.
If you hold the end of the nozzle, injury from the scissors may result.
初次使用縫紉机前需添加机油以保證机器各部机械部件的润滑，
以延長机器壽命

3.加油过程中觀察油量視窗（2），使油量計（3）稳定在上、下
基線之間
注：油量計不可超过視窗上基線
如油量計（3）低於下基線，则必須添加机油
Before the first time use this sewing machine, you need to add
oil to ensure the lubrication of the mechanical parts of the
machine,to prolong the service life of the machine
1. open the oil rubber (1)
2. add oil into the machine
3. look at the oil window (2) during adding oil,to make the oil
guage (3) is steable between the top and bottom baselines
Note: the oil guage can't be over the top baseline in the window
If the oil gauge (3) is lower than the buttom baseline,machine
must be added oil

4.面線的穿法 THREADING THE UPPER THREAD
注 意 CAUTION
在穿線过程中，請切断电源。当誤按动起动开关时，縫紉机动作会导致人员受伤。
Turn off the power switch before threading the upper threadl.
The machine may operate it the treadle is depressed by mistake,which could ressult in injury.
·在穿引面線之前轉动手輪，抬高挑線桿（1）。
这样会使穿引更加容易，並防止面線在縫紉开始时
脫落
·Turn the machine pulley and raise the thread
take-up(1) before threading the upper thread.

当針桿（1）从最低位置向上移动1.8mm（2.2mm用M和H規 格 ），
到达基線（b）与針桿軸套（2）下端对齊的位置时， 梭尖端
（3）应与机針中心（4）对齊，如图所示。
（此时，針孔上边緣与 梭尖的距離为0.5至0.7mm。）
1.轉动縫紉机手輪，使針桿（1）从最低位置上升到如图
所示的基線（b）与針桿軸套（2）的下端保持对齊为止。
2. 鬆固定螺釘（5)[3个]，使 梭尖（3）与机針（4）的
中心一致。
此时， 梭尖（3）与机針（4）之間的間隙为0 ~ 0.05mm
3.拧紧固定螺釘（5）[3个]。
The tip of the rotary hook (3) should be aligned with the center
of the needle (4) when the needle bar (1) moves up 1.8mm
(2.2mm for -M and -H specifications) from its lowest position
to the position where reference line (b) is aligned with the lower
edge of the needle bar bush (2) as shown in the illustration.
(The distance from the upper edge of the needle hole to the
rotary hook tip will be 0.5 to 0.7mm at this time.)
1.Turn the machine pulley to raise the needle bar (1) from its
lowest position until reference line (b) is aligned with the lower
edge of the needle bar bush D (2) as shown in the illustration.
2.Loosen the set screws (5), and then align the tip of the rotary
hook (3) with the center of the needle (4).
The distance between the tip of the rotary hook (3) and the
needle (4) should be approximately 0-0.05mm.
3. Securely tighten the set screws (5).

9. Adjusting the rotary hook lubrciation amount
CAUTION
Be careful not to touch your fingers or the lubrication amount check sheet against moving parts such as the rotary
hook or
the feed mechanism when checking the amount of oil supplied to the rotary hook. If care is not taken, injury
may result.
Use the following procedure to check the amount of oil being supplied to the rotary hook when replacing the rotary hook or
when changing the sewing speed.
<Checking the lubrication amount>
1. Remove the thread from all points from the thread take-up
lever to the needle.
2. Use the lifting lever to lift the presser foot.
3. Run the machine at the normal sewing speed for
approximately 10 minutes without sewing any material
(following the same start/stop pattern as when actually
sewing).
4. Place the lubrication amount check sheet (1) to the left of
the rotary hook (2) and hold it there. Then run the sewing
machine at the normal sewing speed for 10 seconds.
(Any type of paper can be used as the lubrication amount
check sheet (1).)
5. Check the amount of oil which has spattered onto the
sheet.
If adjustment is necessary, carry out the following operations
in "Adjusting the lubrication amount".
NOTE:
If the lubrication amount does not match the correct
amount shown in the illustration at left (if the amount of
spattered oil is too much or none at all), turn the adjusting
screw (3) clockwise to fully tighten it, turn it back
counterclockwise by 3 1/2 turns, and then carry out the
following adjustment.
<Adjusting the lubrication amount>
1. Tilt back the machine head.
Remove the rubber cap (3).
2.
Turn the adjusting screw (4) to adjust the lubrication
amount.
・ If the rotary hook adjusting screw (4) is turned
clockwise, the lubrication amount becomes greater.
・ If the rotary hook adjusting screw (4) is turned
counterclockwise, the lubrication amount becomes
smaller.
3.
Check the lubrication amount again according to the
procedure given in "Checking the lubrication amount"
above.
* Turn the rotary hook adjusting screw (4) and check the
lubrication amount repeatedly until the lubrication
amount is correct.
