Adjustment Procedure
2) Method of lubrication to the oil tank
Fill the oil tank with oil for hook lubrication before operating the
sewing machine.
Remove oil hole cap ❶ and fill the oil tank with JUKI NEW DE-
1.
FRIX OIL No.1 (part number : MDFRX1600C0) or JUKI COR-
PORATION GENUINE OIL 7 (part number : 40102087) using
the oiler supplied with the machine.
2. Fill the oil tank with the oil until the top end of oil amount indi-
cating rod ❸ comes between the upper engraved marker line
A and the lower engraved marker line B of oil amount indicat-
ing window ❷.
If the oil is filled excessively, it will leak from the air vent hole in
the oil tank or proper lubrication will be not performed. In addi-
tion, when the oil is vigorously filled, it may overflow from the oil
hole. So, be careful.
3. When you operate the sewing machine, refill oil if the top end
of oil amount indicating rod ❸ comes down to the lower en-
graved marker line B of oil amount indicating window ❷.
(Cautions)1. When you use a new sewing machine or a sewing
machine after an extended period of disuse, use
the sewing machine after performing break-in at
2,000 sti/min or less.
2. For the oil for hook lubrication, purchase JUKI
NEW DEFRIX OIL No. 1 (part number : MD-
FRX1600C0) or JUKI CORPORATION GENUINE
OIL 7 (part number : 40102087).
3. Be sure to lubricate clean oil.
4. Do not operate the machine with the oil hole cap
❶ removed. Never remove cap ❶ from the oil inlet
in any case other than oiling. In addition, take care
not to lose it.
3) Method of oil drainage from the oil tank
When carrying the sewing machine or during maintenance ser-
vicing, it is possible to remove the lubricant from the oil tank.
1. Let the sewing machine fall down.
2. Insert the oil pan in the undercover.
3. Turn the oil drain screw ❹ of the oil tank ❺ to drain oil.
4. A maximum of 200ml of oil (to the MAX line) is contained in the
oil tank ❺.
(Cautions)1. Be careful not to forget to tighten the oil drain
screw ❹. Otherwise, this can be a cause of oil
leakage.
2. Do not tighten the oil drain screw ❹ too much.
Otherwise, this can be a cause of oil leakage as a
result of breakage.
Results of Improper Adjustment
◦ If too much oil is replenished,
there will be oil leakage from the
air relief hole of the oil tank ❺. In
addition, there can be possibility
of failure in adequate lubrication.
◦ Violent lubrication can result in
overflow from the lubrication hole.
◦ Lubricant shall be removed,
without fail, when transporting the
sewing machine.
◦ Due to vibration during transpor-
tation, oil leakage may be caused
through the air relief hole located
on top of the oil tank ❺.
