6. MACHINE OIL AND FILTER REPLACEMENT
6.1 OIL SUPPLY
The lubricating oil recommended for our
sewing machines is TELESSO 33. To supply
1. Remove the oil pot on top
of the machine top cover.
Insert a funnel into the
opening and pour the oil
into the funnel.
2. Pour in the oil only
until the oil level reaches
between the two marks on the
oil gauge.
3. Replace the oil pot.
Fig. 3
Note: While the machine is in operation, watch to see the
oil is splashing on the inside of the oil pot.
6.2 DRAINING THE OIL
To drain the machine oil, remove the oil drain plug from the
front of the reservoir.
6-3. REPLACING THE FILTER
1. Remove the cover plate,
"A" on the bottom of the oil
reservoir. Filter "B" can
now be seen.
2. Remove the filter by
gently pulling it from
the feed port stem, "C".
3. Replace a new filter onto
the feed port stem.
NOTE:
1. Always check the oil gauge before using the machine to
ensure the oil level is correct.
2. Use only the oil specified or its equivalent.
3. there is no oil splashing in the oil pot, even though the
oil level is correct, this suggests there is a clog in the
oil filter or oil line. Clean or replace the oil filter.
The .inside of the oil reservoir should also be cleaned
.periodically.

7. THREADING AND TENSION ADJUSTMENT
7-1 THREADING
Place the thread through the eyelets and guides according
to the diagram below< Lines "D" represent needle threads,
line "E" is the top cover thread, and line "F" is the
looper thread.

7-2. TENSION ADJUSTMENT OF THE THREAD
The appropriate thread tension varies according to the
sewing conditions (the kind of fabric, the type of thread,
the stitch length used, etc.). Adjust the thread tension
with the tension regulator nut to suit the sewing conditions.
A
Turning the regulator nut clockwise
increases the tension. Turning the
regulator nut counter clockwise
decreases the tension*
NOTE: The thread tension should
be maintained as low as possible
to form a good stitch. Setting
the thread tension unnecessarily
high is likely to cause thread
breakage or skipping.

FIG. 24
THE EXTREME LEFT POSITION OF THE MOVABLE
KNIFE IS SHOWN IN FIGURE 1 ABOVE.
THE CORRECT POSITION IS AS FOLLOWS: THE
MOVABLE KNIFE MUST PASS THROUGH THE
NEEDLE THREAD LOOP(S) AND STOP IN SUCH A
POSITION THAT THE LOOPER THREAD IS BEHIND
THE LOOPER THREAD BLADE AND THE NEEDLE
THREAD(S) ARE BEHIND .THE NEEDLE THREAD
BLADE.
PLEASE OBSERVE THE FIVE POSSIBLE CASES
ILLUSTRATED AT THE RIGHT:
In Case (a), neither the needle thread
nor the looper threads are cut.
In Case (b), both the needle thread
and the looper thread are cut. However,
since the looper thread is not being cut
by the looper thread blade, it will not
be caught under the plate spring for
holding and will not be picked up with
the next stitch.
In Case (c), neither the needle thread
nor the looper threads are cut.
In Case (d), both the needle thread and
the looper thread will be cut. However,
because the movable knife did not pass
though the needle loop, the needle
thread will be cut in the wrong position
and an irregular feeding of the remain
ing needle thread will result.
In Case (e), the knife is in the correct
position and all of the threads will be
cut properly and the looper thread will
be caught and kept under the plate spring.
