b.
Sewing head only
The sewing
head
requires a drive motor that must meet the following specifications:
motor rating¾
HP
and
rated
load
speed 2.800
rpm.
Use a pulley
80
mm
in
diameter
to
match the V
belt.
Verify direction of rotation (FIG 1.1)
Prior
to
starting
the
sewing machine, always make sure
to
pour about 1,5 I of
oil
into
the machine.
See previous paragraph for more information about this.

Lubricating the sewing head
Utilising splash lubrication, the sewing head
is
designed for optimum lubrication of
all
the components concerned.
To
get the maximum performance, never
run
the
machine with oil level lower
than
the minimum level
line.
The sight-glass allows quick
determination of
the
oil level (see
FIG
1.1+1.4).
ATTENTION: the machine should NEVER RUN WITHOUT
OIL.
The machine will loose daily a small amount of
oil.
An
inspection at periodical intervals
is
recommended. If required, refill the oil reservoir
by
unscrewing the filler
plug
marking OIL just above the sight-glass.
Very important: oil type SP68.
The type of
oil
to
be
used
in
this sewing machine should
be
of following viscosity:
SP68.
Recommended
oil
types: CASTROL-ALPHA SP68 or any similar
oil
grade.
ATTENTION:
Use
of low-viscosity oils
will
result
in
poor lubrication properties
and
excessive wear, which
in
turn will necessitate early renewal of the internal parts.
Conversely, use of high-viscosity oils
will
lead
to
lines clogging, which
in
turn will
necessitate early renewal of the spare parts from lack of lubrication.
VERY IMPORTANT:
OIL
should
be
completely removed
and
new oil should
be
added
( 1.5
I.)
ONCE A MONTH. This is best done after a
few
hours
of
operation
Remove the
plug
for oil draining underneath the machine
and
let the oil leak
in
a
bucket. Replace the
plug
and add
new oil (1.5
I)
through the
plug
marked
OIL.
If
the oil
is
strongly polluted, it
is
recommended
to
remove
the
cover underneath the
machine
and
to
remove
all
excess deposit, which has accumulated
on
the cover.
Change the gasket (25839J)
and
close the cover. Place the machine
on
the table
and
refill the machine with oil as described above.
