Construction
The
sheet
metal
shear
QSz
636-1
is
an
electric -tool
of
Class
II
and
is
in
accordance
with
the
VDE
regulations
0740.
The
protec-
tive
insulation
is
additional
to
the
normal
insulation
and
pro-
tects
the ope
rator
against
electric
accidents
which
may
be
caused
by
defects
in
the
normal
insulation.
The
pole
housing
is
insulated
by
the
motor
housing
made
of
shockproof
Polyamide
and
the electric
parts
of
the
armature
are
protected
by a sepa-
rating
insulation
against
the
drive
shaft.
The
machine
is
supplied
with a two-core
cable
without
earth
wire
and
must
not
be
earthed.
The
high
voltage
test
is
made
with
the
prescrib
ed
test
voltage
of
4000
Volts.
The
machine
is
radio-suppressed
accor-
ding
to
radio
interference
degree
0875.
Type
QSz
736-1 (42 V)
is
of
the
same
design,
but without
double insu
lation.
This
type
must
be conne
cted
with a two-core
cable
without
earth
wire.
To
prevent
the
overbridging
of
the
insulation
no
additional
marking
plates
and
signs
must
be
riveted
or
screwed
on
the
housing.
We
recommend
the
use
of
transfers
only.

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
in-
serted
and
adjusted
in
accordance
with
the
instructions. Stops
or
jams ·only
occur
when
shear
is
worked
in
the
wrong
position
a
nd
will
be eliminated
as
soon
as
the
shear
is
brought
by the
right
tou
ch
in
the
right
position.
Do
not
use
force!
If
necessary
switch
off
motor
and
restart
cutting
operation.

An
eccentric
axle
(43)
is
to
be
seen
at
the
end
side
of
the
housing;
it
should
be
turn
ed
with a screwdriver, so
that a wide
gap
is
reached
between
plunger
and
shoe
. Insert
the

so
that the

of
the
blades
overcross
at
0,1
mm (0,004 in.)
to
0,6

(0,02 in.).
A
little
distance

up
to
0,3

When

The

is
to
say,
the
gap
"L"
between
the
cutting

of the
two

(L,

be
proper

is
very
important
for a fa
