Adjustment Procedure
2) Method of lubrication to the oil tank
Fill the oil tank ❺ with oil for hook lubrication before operating the
sewing machine.
1. Turn on the power of the sewing machine, remove the oil hole
cap ❶, and fill the oil tank with supplied NEW DEFRIX OIL No.
1 (part number: 40214211 MDFRX1600C0) or JUKI CORPORA-
TION GENUINE OIL 7 (part number: 40102087).
(Cautions) The power is turned on, and therefore, do not put your
hand into operating parts.
2. When the oil amount in the oil tank reaches the maximum point,
the
on the panel starts blinking and an alarm sounds.
Stop filling oil.
If the oil is filled excessively, it will leak from the air vent hole
in the oil tank ❺ or proper lubrication will be not performed. In
addition, when the oil is vigorously filled, it may overflow from
the oil hole. So, be careful.
3. When the oil amount in the oil tank reaches the certain low
point, the
on the panel starts blinking and an alarm
sounds. Supply oil.
(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 : 40214221/
MDFRX1600C0), 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 servic-
ing, 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. Pull out the lubrication pipe of the oil tank ❺ and drain oil.
4. A maximum of 160 ml of oil (to the MAX line) can be contained in
the oil tank ❺.
Results of Improper Adjustment
○ 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.
