SAFETY REGULATIONS
Failure to comply with the e afety regulation may cau e injury to
individual or damage to the machine
The machine must be installed by specifically trained specialized personnel, after having carefully read the instructions.
The machines have been designed and built to meet safety requirements for operation in dry and accurately cleaned
environments and for sewing dry fabric.
The machines are equipped with accident prevention guards; the user must not, for any reason, disassemble, remove
deform or disable the guards, even partially, since risks may arise from such for the operator or any other individuals.
The machine must be used exclusively for the use it is intended for, complying with all the safety regulations in force and
manufacturer’s instructions to avoid risks of accident. In particular, the machine must never be used:
- holding or pulling the fabric while sewing;
- with incorrect clothing, i.e. loose and flowing, long hair not tied back, etc.;
- continuously by disabling the start pedal (for example by putting a weight on it);
-keeping a hand on the hand wheel with the machine running;
-feeding the fabric using tools or equipment (tweezers, scissors, screwdrivers, etc.).
The machine must absolutely be turned off using the main switch before carrying out any replacement, disassembly or
assembly operation, for example, replacement of the needle, sewing parts (presser foot, thread loading bobbin, chain-
stitch guide, crochet, needle plate, etc.), threading etc. when you leave the work area and when maintenance work is
done.
Maintenance work must be carried out by properly trained personnel.
Before working on the electrical system, or in general on any live parts, the plug must absolutely be removed from the
socket. Work on the electrical system must be done by specialised electricians.
Work on live parts and devices is forbidden.
Before reconnecting to the mains make sure that all the guards have been closed and any protection devices which have
been removed are refitted.

20 TECHNICAL FEATURES

1 – SEWING MACHINE INSTALLATION
BENCH AND LAMP ASSEMBLY (Fig. 1)
Secure the table (1) to the bench using the holes set
up for securing the hinges, fit the drawer holder
support (2), fit the multiple bobbin holder (3) in the
lower part of the head, so that the chromed rod for
threading the thread is in a vertical position above the
head, fit the front work surface (4), complete with
overturning part, to the screws on the bench.
Loosen the fixing screw of the lamp (5), turn it to work
and retighten the screw previously loosened.
Use a soft cloth to clean the work area (presser foot
and needle part unit)
MOTOR VOLTAGE
Electrical supply: 220 AC
TEST RUNS
The sewing machine is controlled by a motor with
CPU used fr progressive control of the speed the
pedal (6) Fig. 1.
Insert the light plug in the mains socket, insert the
air tube with and operating pressure of 5 atm. (7)
Fig. 2.
With the machine turned,pushing the pedal forward,
the speed of the sewing machine increases
progressively until the maximum pre-set rpms are
reached; when it is released the sewing machine
goes into the low needle position, both in the 1
st
and
2
nd
cycle, at a constant speed.
With a back heel movement of the pedal (i.e.
backwards) the needle moves to the threading
position.

2 – DESCRIPTIVE CHART OF WORK CYCLES
DESCRIPTION
The formation of the stitch occurs in two work cycles.
1
t
cycle: Formation of the stitch on the upper part of the fabric.
The 1
st
cycle starts with the threaded needle which descends from the
P.M.S. with the hook (46) which starts the stroke to pick-up the thread
on the needle and end with the needle returning to the P.M.S.
without the thread, while the upper hook is in the standby position
behind the needle.
Fig. 3 - 3A - 3B.
2
nd
cycle: Formation of the stitch on the lower part of the fabric.
The 2nd cycle starts with the needle without thread which descends
from the P.M.S. with the hook (46) in standby position behind the
needle and ends with the threaded needle returning to the P.M.S.,
while the hook (46) starts the stroke to pick-up the thread on the
needle Fig. 4 - 4A - 4B.
To complete the two work cycles the needle bar, upper hook and
rotating hook ( 47) carry out the following movements:
A) The needle bar makes two back and forth strokes.
B) The upper hook (46) makes only one back and forth stroke.
C) The rotating hook (47) makes two completed 360° turns.

4 – ADJUSTING NEEDLE AND POINT
Needle replacement (Fig. 5)
Loosen clamp 26 and remove the needle by pulling it up.
Select the needle size with the corresponding needle guide from those
indicated in the table.
Insert the needle with the flat part of the shank towards the left in the
clamp 26 and needle guide hole 17.
Place the needle firmly against the ring 25.
Lift the clamp 26 and tighten the screws with moderation.
Point replacement (Fig. 6 / 6A / 7 / 8)
Carefully clean the needle guide groove.
Insert the point in the needle guide groove so that it protrudes slightly
from the rear part.
Lock screw 19 being careful that the point does not move.
Insert the needle and make sure that the pressure the point exerts
on the needle is light.
Insert the needle guide on the needle bar and put the needle in its
position.
Tighten screws 26 and 27.
Lift the needle guide up making sure it moves freely.
N.B.:
At the end of needle and point replacement operations make sure
the needle guide moves on the needle.
Bring the needle to PMS.
Remove the point lift cylinder cap.
Loosen screw 27.
Lift the needle guide until touching the needle clamp and tighten
screw 27.
Make sure lifting and lowering movements are smooth.
Point height (Fig. 7 / 8)
The height of the point (18)
needs to be established in
relation to the needle. The
adjustment is exact when the
point closes the space between
the two needle hooks,
surpassing the point of the lower
one by 0.8-1.2 mm (varies
based on needle size) and the
needle bar is at P.M.S. Fig. 7.
The adjustment is made using
the aluminium cap (10). By
rotating clockwise the point
rises, anti-clockwise it lowers.
Lock the adjustment
by tightening the screw (36)
inside the cap. Fig. 12.

5 – ADJUSTING NEEDLE BAR HEIGHT
Turn the hand wheel until the needle bar is at its P.M.S.
Loosen the guide clamp screw (20).
Adjust its height so that the distance between the needle tip and needle plate measure with a calliper (29) Fig. 9 is in
compliance with the timing table (e.g. 15.8 mm).
Carefully tighten the clamp (20) to avoid deforming the external part of the needle bar. When carrying out these
adjustments it is advisable to slightly direct the needle bar towards the left.
With the needle bar at P.M.I. the reference notch ( 30 ) on the hand wheel needs to be aligned with the reference notch
(31) on the sewing arm.
Example of needle bar height to 15,8 mm.
