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.
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
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.

Maintenance
and
Lubrication
The machine
must
be
(according
to use)
greased
once
. a
day
at
the
grease
point
with a grease
gun (grease
Sst
1).
It
should
be
greased
when
the
machine
runs
in
no
load,
till
clean
grease
goes
out
at
the
plunger.
Before
carrying
out
any
maintenance
work,
always
remember
to
pull
out
the
plug.
After
300
working
hours
clean
cool
air
openings
at
the
motor
housing.
Blow
out
the
motor
with
dry
pneumatic
air.
Renew
gear
grease. For
this
purpose
take
out
shear
head
according
to
§ 6 (4).
Only
use
Fein spec
ial
grease
Sst
1.
This
grease
must
not
be
mixed
with
other
greases.
Quantity
of

After
900
working
hours
take
apart
the
machine
accord
ing
to
§ 6
and
clean
thoroughly.
Clean
parts
of
the
gearing and ball
bearings
in
clean
solvent
and
pack
with
fresh
grease
Sst
1.
The
space
between
inner and
outer
ring
is
to
be
filled
one
third
with
grease
in
order
to
prevent
overheating
of
the
bearings.
Clean
electric
parts
only
dry.
For
checking the
carbon
brushes, the
carbon
holders
(10, 10 a)
can
be
taken
out
after
unscrewing the
screws
(13).
Make
sure
that
the
carbon
brushes
are
refitted
in their
original
place
and
th
at
they
move
easily
in
their
holder.
They
should
be
replaced
at
the
latest,
when they have
worn
down
to 7 mm
('// ').
Please
only
use
original
Fein
carbon
brushes
(Order
Reference
EZ 11-
62).
After
fitting
new
brushe
s,
run
tool
unloaded
for
about
15
minutes
to
allow
brushes
to
bed
in.
One
pair
of
carbon
brushes
will
be
found
in
the
motor
housing;
please, do
not
forget
to
reorder
them
in
time.
In
order
to
prevent
accidents,
check
cable
at
regular inter
val
s.
To
replace
the
cable,
unscrew
the
screws
(22)
and
(23)
and
re
move
the
