(3) Lubrications.
a. Information for lubrication; (Fig.?)
Before starting the machine, fill oil pan wit h
sewing machine (101 white oil) u p to HIGH mark A.
When you operate the machine after lnbrieatioa. you
will see splashing oil through oil eight window, Note
that the amount the splashing oil is u.nre)ated to the
amount of the lubrication oil, But if the oil level is
lower than LOW mark B, always refill th" oil. 1119 Fig.9
.. Note: New machine(or those who have not been
usedforalong time) must be operated at a •peed of 1500 .s.p.m oil and 011 for 10 minutes
at firu.
b. Adjusting the amount of oil supplied in the front of head(Fi g.8):
The amount of oil supplied in the oil rnervoir in the front of head caD be adjusted
l!y regulating valve of amount of oil(l): turn the resulating valve of amount of oil (1),
when dot A on the regulating valve is parallel to oil i.Dlet tube(2), the amount of oil is
maximun. when l'otating th<i! regulating valve, the a:mount of oi.l witt b~ ~:~duced
gntdually till the dot on the regulating valve is vertical to the oil inlet pipe, the oil
Row regulotor is closed.
c. Adjusting the oil of rotary hook {Plg 9)
White turing the adjusting screw on the lower shaft bush to •+". the amount of oil
will incrense; while turing the adjusting screw to "-" the amount of oil will decrease.
(4) Testing:
a. When m:ichine running, the balance wheel should be counter clockwise.
b. The mnchine can :not run without materials after threading.
c. At the beginning of operating, the s~ed of JD&chine can be over 2500spm. Only
after one or two months of running, the speed of the machine can be increased as per
nature of fab1·ics.
