~LUBRICATION AND RUNNING IN~
ill lubrication
Be sure to oil the following points before using your sewing machine.
1. After setting up the machine , remove adjusting cover screw e. and pour oil in up to the reference line on oil gauge e.
2. Turn the pulley until oil ca p e is up , remove oil cap e and pour oil into oil tank 0 until it is full. If th'e o il in the oil tank
decreases below tank center line e.the oil will not be drawn into the upper shaft, causing imperfect lubrication. Be sure to
keep the oil in the oil tank above oil tank center line e.
3. Pour about 5 drops of oil into 3 oil cups e and needle bar bushing oil hole e every week .
4.
Remove oil drain screw e from time to discharge the used oil which has collected in the front bed oil sump .
5. Wipe arm jaw e and rear bed oil sump e from time to time· to remove oil from them.

th e hole for the
adjusting cap screw.
4. Stitch length decreases when horizontal eccentric adjusting
screwe isturnedclockwise withscrewdriver, and increased
when
the same screw is turned counterclockwise. Exercise
care to keep the feed dogs clear of the slot in the needle
plate.
5. After the above-mentioned adJustment retighten screw e
securely.

Tight en ca p sc rew e and two set screws 8 securely.
6. Loosen
set screw •. move looper holder 8 in the arr ow direction until the distance between the needle cen ter and the looper
tip is 3.2 to 3.5 mm, and ret ighten set sc rew • securely.
f2] Needle Bar Height Adjustment
•
Looper forward travel
Looper backward travel
Adju st the needle bar height so that the looper thread eyes will match the needle eyes in the f or ward and backward travels of
the loopers.
(Adjusting m•thod)
1. Turn the pulley toward yo ur self until the loopers move forward from the rightmost position to a point where the looper
thread
eyes are in line with the needles eyes.
2. Open face plate e.loosen needle bar clamp screw e.and move need le bar e up or down until the looper thread eyes are
in line with the n ee dle eyes.

131 Timing of Loopers Running Clear of Needles
0 ,.,
-----
The loopers run in back of the needles in their forward travel and in front of the needles in their backward trave l.
Adjust the clearance between the needles and the loopers to anywhere from 0 to 0.05 mm in both the forward and backward
.ravel s.
(Adjusting method)

3. Tum the pulley toward yourself again until the tips
of the loopers come to the centers of the needles.
4. Loosen stop screw e. move needle guard 8 to the
left
or to the right, and adjust so that the clearance
between the needles
and the tips of the loopers will
be
