2. 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
w
hen
connecting.
To prevent damage to the insulation no
additional
marking plat-
es
must be riveted
or
screwed to the
casing. We
recommend the
use of
transfers
only.
The machine performs quick
and
clean cuts
w
h en blades
are
inserted and adjusted in
accordance
with the
instructions.
Stops
or jams
only
occur when
shear
is
worked
in the
wrong
position
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.

(45)
until
the corners
of
blades
at
highest
position
of plunger are 0.4
mm
(0.2 in.)
apart.
Then
fasten screw (68).
Adjust
shoe blade in order to
fit
with sheet thickness by
means
of
turning
set screw (72) until
the
gap
between
blades
is
set for
sheet of 40 kp/mm
at
0.7 mm (0.25
in.).

and c.
Control
angle
with
gauge.
Attention!
Do
not cut welding
seams.

To
grease let
the
shear run
at
no load
until
clean
grease
emerges
at
the plunger.
After 300
duty hours
clean
air
openings
of
th
e
motorhousing
and
the
motor
by blowing

t
he
tool with
dry
pneumatic air or by
means
of a
