10. Lubrication
1) Before running the sewing machine, remove
rubber plug
❶
from the top of the machine arm,
and add oil through the oil inlet using accessory
funnel
❸
supplied with the sewing machine.
2) Visually check the oil quantity through oil sight
window
A
on the top surface of the bed.
Oil sight window
A
has two lines.
• Upper line : MAX. line
B
• Lower line : MIN. line
C
While visually observing the oil quantity through
oil sight window
A
, add oil until the blue line
D
meets MAX. line
B
(state
③
).
* When oil is added until MAX. line
B
is reached,
the oil quantity becomes 450 cc.
* Check the oil quantity while the sewing machine
is at rest.
3) When you operate the machine after lubrication,
you will see splashing oil through oil sight window
❷
if the lubrication is adequate.
* Note that the amount of the splashing oil is
unrelated to the amount of the lubricating oil.
4) When the remaining oil quantity reaches MIN.
line
C
or lower, red line
E
appears to warn the
oil shortage (state
①
).
If red line
E
appears on oil sight window
A
after
finishing sewing machine operation, add oil until
state
③
is restored.
1. When you use a new sewing machine
or a sewing machine after an extended
period of disuse, use the sewing ma-
chine after performing break-in at 2,000
sti/min or less.
2. For the oil lubrication, purchase
NEW
DEFRIX OIL No.1 (Part No. : 40157520)
or JUKI CORPORATION GENUINE OIL
7 (Part No. : 40102087).
3. Be sure to lubricate clean oil.
4. Be aware oil leakage can occur if the
surface of added oil quantity exceeds
MAX. line
B
.
5. Transporting the sewing machine with
the sewing machine filled with oil can
give rise to the risk of oil leakage. Be
sure to discharge oil from the sewing
machine through drain cock
❹
.
WARNING :
1. Do not connect the power plug until the lubrication has been completed so as to prevent acci-
dents due to abrupt start of the sewing machine,
2. To prevent the occurrence of an inflammation or rash, immediately wash the related portions if oil
adheres to your eyes or other parts of your body.
3. If oil is mistakenly swallowed, diarrhea or vomitting may occur. Put oil in a place where children
cannot reach.
