plug
wiring
should
be
effected
according

Before
connecting the
sewing
machine
to
an electrical supply ensure that
the
voltage
marked
on
the rating
label
of the machine
is
the correct
voltage for
your
electrical supply. If
it is
not,
do not
use the
machine
but
refer
back
to your
dealer.
Connecting
to your
Electricity supply
The sewing
machine
has a
flexible
two
core
mains
lead
permanently
connected
to the
foot
control.
At
the
free end
of the lead
a
suitable
plug
should
be fitted.
Important
The
wires in
the mains
lead of
this appliance
are coloured
in accordance
with the
following
code:
BLUE:
NEUTRAL
BROWN:
LIVE
As the
colours
of
the wires
in the
mains lead
of
this appliance
may
not corres
pond with
the
coloured
markings
identifying
the terminals
in
your
plug, proceed
as
follows:
The
wire which
is
coloured
blue
must
be
connected
to
the terminal
which
is
marked
with
the letter
N
or
coloured
black. The
wire
which
is coloured brown
must
be connected
to the
terminal
which is
marked with
the
letter
I
or
coloured
red.
If
using
a 3-pin
plug do not
make
any connection
to
the
terminal
marked with
the
letter E
or by
the earth
symbol
*
or
coloured
green
or green
and
yellow.
Your
Husqvarna
sewing
machine
is
double
insulated and no
earth connection
is
necessary.
If
a 13 amp
fused
plug is used,
it should
be
fitted with
a 3
amp fuse.
It is in
your
own
interest
to ensure
that
the
plug
is correctly
fitted
to
the mains
lead. If
in
doubt
consult
aqualified
electrician,
as Husqvama Limited
cannot
regard
the
repair of
faults
on the
plug
connection
as a

under
the
terms
of the guarantee.
This appliance
conforms
with the requirements
of E.E.C.
directive
No.
761889
relating
to
radio interference.
