– 7 –
1. When using a new sewing machine for the rst time or using the sewing machine which has not
been used for a long time, run in the sewing machine at a sewing speed of 1,000 sti/min or less and
check the oil quantity in the hook before use.
In the case the oil does not come from the hook, turn the oil amount adjusting screw counterclock-
wise to make sure that the oil is fed from the hook. After that, adjust the amount of the oil fed from
the hook appropriately. (Refer to "■ Adjusting the oil quantity in the hook" p.8.)
2. For the oil for hook lubrication, purchase JUKI NEW DEFRIX OIL No. 1 (Part No. : MDFRX1600C0) or
JUKI MACHINE OIL #7 (Part No. : MML007600CA).
3. Be sure to lubricate clean oil.
3. PREPARATION OF THE SEWING MACHINE
WARNING :
1. Do not connect the power plug until the lubrication has been completed so as to prevent accidents
due to abrupt start of the sewing machine.
2. To prevent the occurrence of an inammation 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.
■ Lubrication procedure
Fill the oil tank with oil before operating the sewing
machine.
1) Fill the oil tank with JUKI NEW DEFRIX OIL
No.1 (Part No. : MDFRX1600C0) or JUKI MA-
CHINE OIL #7 (Part No. : MML007600CA) using
the oiler supplied with the machine from section
C.
2) Fill the oil tank with the oil until the top end of
oil amount indicating rod
❷ comes between the
upper engraved marker line
A and the lower
engraved marker line
B of oil amount indicating
window ❶.
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. In addition, when the oil
is vigorously lled, it may overow from the oil
hole. So, be careful.
3) When you operate the sewing machine, rell
oil if the top end of oil amount indicating rod
❷
comes down to the lower engraved marker line
B of oil amount indicating window
❶.
