2) Method of lubrication to the oil tank
(DDL-9000B-S and DDL-9000B-M only)
1. Remove the lubrication hole cap
and replenish the JUKI New
Defrex Oil No. 1 (Part No.: MDFRX160000) or the JUKI Machine Oil
7 (Part No.: MML007600CA) with the use of an accessory oilcan.
2. Feed the oil until the tip of the oil level indicator bar
stays between
the upper and lower engraved marker lines A and B of the oil gauge
window . Be careful at that time that no dust and others enter the
interior.
3. Lubrication is needed if the tip of the oil level indicator bar comes
below the lower engraved marker line B of the oil gauge window
while the sewing machine is used.
(Cautions) 1. When using a new sewing machine or the one that
has not be used for a long time, trial running is
required at the speed of 2000sti/min or below.
2. The hook oil shall be the one recommended by Juki.
3. Clean oil shall be replenished at all times.
4. Never operate the sewing machine while the
lubrication hole cap is removed. Carefully manage
this cap not to loose it.
(For reference) Even after making the sewing machine fall down, it is
possible to check the quantity of oil in the oil tank.
The quantity of oil is adequate if the oil level stays
between the MAX and MIN lines.
3) Method of oil drainage from the oil tank
(DDL-9000B-S and DDL-9000B-M only)
When carrying the sewing machine or during maintenance servicing,
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 of the oil tank to drain oil.
4. A maximum of 200ml of oil (to the MAX line) is contained in the oil
tank .
(Cautions) 1. Be careful not to forget to tighten the oil drain screw
.
Otherwise, this can be a cause of oil leakage.
2. Do not tighten the oil drain screw too much.
Otherwise, this can be a cause of oil leakage as a
result of breakage.
o If too much oil is replenished, there
will be oil leakage from the air re-
lief hole of the oil tank . In addi-
tion, there can be possibility of fail-
ure in adequate lubrication.
oViolent lubrication can result in
overflow from the lubrication hole.
o Lubricant shall be removed,
without fail, when transporting the
sewing machine.
Due to vibration during transportation,
oil leakage may be caused through
the air relief hole located on top of
the oil tank .
