15. Oil mass adjustment of rotating hook
1. Adjustment method
1) Adjust the oil mass of rotating hook using adjusting
screw ①: Screw down (turn it to the right) adjusting
screw ① to raise the oil mass,or unscrew (turn it to
the right) the adjusting screw to lower the oil
mass. Amount repeatedly until the lubrication
amount is correct.
2) Check the lubrication amount again after the sewing
machine has been used for approximately two
hours.
2. Confirming the Oil Mass
1) Remove the thread from all points from the thread
take-up to the needle.
2) Use the lifting lever to lift the presser foot.
3) Run the machine at the normal sewing speed for
approximately 3 minute without sewing any material
(following the same start/stop pattern as when
actually sewing)
4) Place the lubrication amount check sheet ②
underneath the rotary hook ③ 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 ②)
5) Check the amount of oil which has spattered onto
the sheet ②.
Caution:
1. Prior to the above-mentioned operation, remove the
knockout plate and check whether there is oil in the oil
box.
2. Do not use fingers to touch the hook or other running
components of feeding mech anism when checking
the amount of oil for the hook to avoid the accident.
3. 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.

3. Guide sample of oil mass adequacy
1) The guide sample shown in the right-hand
figure(see Fig. 24) may be finely adjusted
(increased or reduced) as per different sewing
processes; however, excessive increase or
reduction shall be avoided. Too little oil mass may
lead to rotating hook heating, and over
much oil mass may lead to contamination of the
sewing materials.
2) Test the oil mass 3 times using special oil mass
confirmation paper till the oil traces indicated by
the special paper show no changes.

4) Securely tighten the screw ②.
Caution:
1. To prevent the unexpected startup of sewing machine, switch off the power supply before the operation is
conducted.
2. The take-up spring is already adjusted properly before the machine leaves the factory as a rule, and it requires
readjustment only for sewing of special materials or usage of special stitch threads.
23. Adjust the synchronization of the needle and hook
1. Unscrewing the two positioning screw ① of hook.
2. Rotating the hand wheel to make needle bar ② lift from the lowest place, when using needle DBX1 and DPX5, the
mark B on needle bar ② should match to the bottom of lower needle bar ② bushing, when using needle DAX1, the
mark D on needle bar ② should match to the bottom of lower needle bar ② bushing.
3. Moving the hook to match the hook point ③ with center of needle ④. Meantime, make the space between the hook
point ③ and needle ④ 0~0.05mm.
4. Tightening two positioning screw ① of hook.
Caution:
1. To prevent the unexpected startup of sewing machine, switch off the power supply before the operation is
conducted.
2. If the clearance between notch on needle and thread hooking tip of rotating hook is too small, rotating hook tip may
be worn; if the clearance is excessive, skipped stitch may take place.
