4-2 INSTALLAHON OF THE NEEDLES
Install the needles so that their Clearance Above
the Eye (CAE) is exactly in the back. Be sure to
insert the needle all the way into the needle clamp
so that it touches its base. Then tighten set screw A.

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.
5
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.

8. ADJUSTMENT OF THE LOOPER POSITION
8-1 THE LOOPER-NEEDLE DISTANCE
At the time the looper is in
its extreme right position,
the needles must be in their
lowest psotion. At this
time, the looper-needle
distance, "D", from the tip
of the looper to the right
side of the most right needle
must be Amm. This adjustment may be made by loosening the looper
drive lever clamp screw, "E" and repositioning the looper holder.
8-2 THE LOOPER-NEEDLE CLEARANCE
128mm
o
Fig. 7
The looper must pass behind the needles to catch the needle
loop to form the stitch. The looper position must be adjusted
so that at this time the clearance between the tip ofthe looper,
"A" below, and the needle, "C", is 0 to 0.05mm.

This adjustment may be made by loosening the clamp screw, "H",
on the looper rocker lever, "B", and repositioning the looper
behind the needles.

The correct needle bar heights for the various needle gauges
are listed below. To adjust, remove the machine head cover.
Next, loosen the clamp screw,"?", shown in figure 11*
Move needle bar,"G", to the appropriate height and retighten
the clamp screw.

NOTE: The needle bar
height is the dimension
from the top face of the
needle plate to the tip
of the left-^ost needle,
(see Figure 10)

The feed length adjustment of the R-9000 series machines
is by a pushbutton system. To adjust, lower the front cover
on the bed of the machine. You will see pushbutton,"A", shown
in the illustration. Push the button and turn

the handwheel until the pin falls into place. Then turn the
handwheel while holding down the button. Turning the handwheel
in the "I" direction makes the stitch larger. Turning the hand-
wheel in the "H" direction -6- makes the stitch shorter.

1 1 ADJUSTMENT OF THE DIFFERENTIAL FEED
Expose the access port by removing the rubber plug as shown
in Figure 13. At this time you can see nut "B". To adjust
the differential feed, loosen nut "B" and move the lever up

or down the differential guide plate. Moving the lever up
increases the differential. Moving the lever down decreases the
differential. Retighten nut "B",
12. ADJUSTMENT OF THE FEED DOG HEIGHT
As shown in Figure 14, the height of the
feed dog should be one full
tooth height or 0.8 to 1.2mm.
The height of the main feeder
is adjusted by loosening set
screw "A".
The height of the differential
feeder is adjusted by set
screw "B".

adjustment of the needle guard
As the looper is moving from right
to left behind the needlesi the tip
of the looper will reach the center
line of the first (right-most)
needle. At this time, the needle
guard' must be in contact with the
needles. The dimension from the
point of the contacting surface to
the tip of the needles should be
0.8 to 1mm and the right-most
needle should be pushed slightly
forward 0.1 to 0.3mm by the needle
guard» as shown in Figure 16.
Adjustments of the needle guard height and angle
with respect to the needle line are made with set
screw A. Front-back position adjustment is made
with set screw "C". Retighten all set screws
after adjusting.

15. ADJUSTMENT OF THE TAKE UP 6-7o/d
As shown in Figure 17, the dimension
between the bottom of the retainer "B",
and the take up plate, "E", should be
6 to 7mm. Adjust this dimension with
set screw "F". Also, as shown, the eye
of the looper thread guide, "A", should
be in line with the center of the main
shaft. Adjust the position of the thread
guide with the set screw "G".

As shown in Figure 18, the looper thread
should be released from the take up cam when the tip of the
left-most needle I reaches the bottom surface
of the looper at V the time the needles are
on their downward stroke.

POSITION OF THE NEEDLE LEVER EYELET
At the time the needle lever eyelet is in its upper-most
