RUN MACHINE AT
RECOMMENDED SPEED
1. Run new machine at a 20% less speed
than maximum for the first 4 weeks.
At the end of 4weeks, original oil
should be drained out and replaced.
Thereafter the machine may be oper
ated at normal speed.
2. Keep enough amount of oil in the ma
chine; the top of Oil Level Indicator O
should be always between the two lines
of Oil Level Sight Window. See page
12.
3. While machine running, OilMonitor©
is green, which shows the normal oil
circulation inside the machine. If Oil
Monitor © is red, something ex
traordinary may be caused in the oil
circulation; check the oil amount or
Oil Filter. See page 12.
4. Before starting machine for the first
time, or if machine is idle for more
than two weeks, manually lubricate
Needle Holder Guide Stud O, Upper
Looper Holder © and the oil hole ©.
The Oil Hole © requires daily lubrica
tion before morning start.

Table and Rest Board as shown in
Table 1.
2. Fix Rest Board 0 rigidly under
Machine Table.
3. Set Waste Chutes O O and O as
shown.
4. Put Cushion Rubbers O and 0 on
Rest Board 0 Set Machine on Board
©, making sure the holes of Oil
Reservoir fit the pins of Cushion
Rubbers O-
Note: The table of the thickness of 45mm or more is recommended for E52. Using a
thin table may cause excess vibration/noise during sewing.

DRIVING MOTOR PULLEY AND
BELTING
Each machine should use a motor and
belt of the following specifications:
1. Clutch motor: 3 phase, 2 pole, more
than 4CX) watts (1 /2HP).
2. Belt: V belt. Type M.
3. Motor pulley: as shown in Table 2.
Machine Pulley
Diameter is 55mm.
Motor Pulley Diameter should be
measured at its outer diameter.
THE TURNING DIRECTION OF
MACHINE PULLEY AND
BELTING Fig. 4
The turning direction of Machine Pulley
is clockwise, seeing the machine from its
right side.
Set Motor so that the belt can be 2cm
bend inward when you press the middle
of the belt lightly by finger.
BELT GUARD AND EYE GUARD
Fig. 5,6
For safety, fit Belt Guard and Eye Guard
properly on the machine before you start
it for the first time.

LUBRICATION
The oil was drained out from the machine
when shipped. Fill Oil Reservoir with
factory supplied oil or equivalent before
operating. Use recommended
type oil
only. Keep the enough amount of oil in
the machine; the head of Oil Level
Indicator should be always between the
two lines 'h' and '1' on Oil Level Sight
Window O.
Change oil entirely at the end of 4 weeks
from starting. After
that, change oil
every half ayear.
Lubricating oil
Use Mobil Velocite Oil No.
10 (ISO VG22) or
equivalent.
12
To fill oil: Fig.7
1. Take out Screw O and pour fresh oil
into Oil Reservoir (QOOc.c. capacity)
until the head of Oil Level Indicator
reaches the upper line 'h' of Oil Level
Sight Window O
2. Re-place ScrewO
To drain oil: Fig.8
1. Remove the machine from its stand
and set it on a table.
2. Screwout Drain Plug O and drain oil.
3. Re-place Plug ©.

Oil filter Fig. 9
Filter O should be kept clean. Lubrication
oil is filtered and delivered to all frictional
surfaces. Clogging of this filter may cause
lack of lubrication and accidental seizure
of parts.
Check and clean Filter Owhen: the oil
amount is proper but Oil Monitor does
not change into green when starting the
machine, the oil is dirty or contains foam,
or the oil jet is weak.
1. Remove Screws o and Cap O.
2. Take out Filter O. Check and clean it,
or replace it with a new one.
3. Re-placeCap 0 and Screws 0.
SILICONEOILFORH.R.
DEVICE Fig. 10
Fill the Reservoir for H.R. Device with
factory supplied Siliconeoil or equivalent.
The oiler containing 50c.c. Silicone oil is
supplied with the machine. Never use
Silicone oil for machine parts lubrication.
To fill the Reservoir:
Open Cap O and pour silicone oil from
here.

NEEDLES
The type of the factory-set needle is
Organ DCx27, Machines can also use
other similar needles to DC x 27. This,
however, may require re-adjustments of
Loopers and Needle Guards.
16
REPLACING NEEDLES
1. Loosen Screw O and
needle.
2. Insert a new needle into the needle
hole as far as it will go.
3. Tighten Screw O after making sure the
long groove on the needle is facing
you.
Note:
When loosening or tightening Screw O,
be careful to use Allen Wrench properly.
This is to avoid the screw hole of Screw
O from damaged.

THREADING
Fig. 13,14,15
Thread your machine correctly as shown
in Fig. 13, 14, 15. Incorrect threading
may cause thread breakage, skip stitches,
or uneven stitch formation.
REGULATING THREAD
TENSION Fig. 13,14,15
Changes of threads, seam width, stitch
length, etc, require re-adjustment of
thread tension.
Adjust individual thread tension as
follows:
To increase tension:
Turn Nut clockwise.
To decrease tension:
Turn Nut counter-clockwise.
Ja.l-.coJ-iifMi. 3'j . A ^ Ji L T < t s
Pass 'A' when stretch threads are used.
Also, pass 'A' when non-stretch threads are used with
the stitch length longer than 2.8mm.
