2. Construction
The
sheet
metal
shear
QSz
663 is
an
electric
hand
tool fitted
with
protective insul
ation
according
to Cla
ss
II
of
the
VDE
Specifications
0740.
In addition
to
the
norm
al i
nsulation the tool is equipped
with
a
further
protective
insu,lation.
Thereby
the
touchable
external
metal
housing is
separated
from
all
internal
parts,
which
can
become live
in
case
of
failure.
The
dustproof
switch
is
built
into
the
plastic handle.
The
tool
is
not
to
be
earthed
and
must be connected
with a two
-core
cable
:
without
earth
wire.
The
r~dio
suppression
of
the
machine
is
in accordance with radio
suppression degree
N.
Type
QSz
63 K
for
low
tension
(voltage
42 V) is
of
the same design,
but
without
double insulation.
To
prevent
the
overbridging
of
the ins
ulation
no
additional
marking
plates
and
signs must be
riveted
or
screwed
on
the
housing. We re-
commend
the
use
of
transfers
only.
3. 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.
Switch must be in
the
"Off"
position
when
connecting.
The
machine
performs
quick
and
clean cuts
when
blades are inserted
and
adjusted in accordance
with the instructions . Stops
or jams
only
occur w
hen shear
is
worked
in
the wrong position a
nd
will be
eliminated as soon as
the
shear is
brought
by the rig
ht
touch in
the
right
position. Use
no
force!
If
necessary switch off
motor
and
restart
cutting operation.
Attention.
Do
not
cut welding seams.

then
be tightened.
Hereafter
the
fixed bl ade should finally be
adjusted
by
set screw
(108) so
that
the
gap

1/10
of
the
sheet thickn
ess
to
be cut.
(e.g. sheet metal
of 2 mm
thickness-

Attention!
Never
work
with
blunt
blades!
For
resharpening, the
blades
ca
n be removed
after
unscrew
ing
the two screws (117). When
sharpening
use
plenty of
coolant a
nd
strictly obse
rve the prescrib ed
cutting
angle.
If
blades are resha
rpened
in
time,
breaking

is
avo
ided
. The fixed blade
and
the
plunger
bla
de
are
interchangeable.
No
claims can be
entertained
for
damage
due
to
work with
materia
l
of
too much strength
or
sheet too thick
or
work
with blunt
blades.

Re-assemble in reverse sequence.
After

should
be
cleaned

For
this
purpo

the
machine is
dismantled
as described

and
the
