Connection
and
Operation
Main
voltage
must
correspond
to
the
operating
voltage
marked
on
the
rating
plate.
The
tool
can
be
plugged
into
plain
or
safety
sockets
without
protective
contact.
Switch
must
be
in
the
"Off" position when
connecting
.
To
prevent
damage
to
the
insulation
no
additional

king plat-
es
must
be
riveted
or
screwed
to
the
casing.
We
recommend
the
use
of
transfers
only.
The
machine
performs
quick
and
clean
cuts
when
bla
des
are
inserted
and
adjusted
in
accordance
with
the
instru
ctions. Stops
or
jams
only
occur
when
shear
is worked
in
the
wrong
pos
ition
and
will
be eliminated
as
soon
as the
shear
is
brought
in the
up-
right
position.
Do
not
use
force!
If
necessary
switch
off
motor
and
restart
cutting
operation.
