2. Construction
This screw-driver
is
an electric
tool of Class
II with
protective
insulat-
ion without
earthing
conductor
and
is in
accordance
with
the VDE
regulations
0740.
The
protective
insulation is
attained by
the
shock-
proof motor
housing
made of Polyamide and by
insulating
the
arma-
ture
against
the
pinion.
The
protective
insulation
is
tested with the
prescribed test
voltage of
4000 V.
The
machine
is
radio
suppressed in
accordance with radio
interfer
ence
degree
N. It
is
supplied
with
a
two-core
cable
w
ithout
earthing
conductor and
must not
be earthed.
T ype ASs 736 for low tension (42 V)
is
of
the
same
design, but
with~
out
double insulation
and
not radio
suppressed.
The machine
is
provided
with
a
reversing
switch for
clockw ise
and
anticlockwise
rotation. It must not be operated when the machine
is running.
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
Before
plugging
m
t he
tool
check that voltage
stated
on the rating
plate
is
in
accordance
with t
he
voltage of
the
mains
supply
.
Switch must be in the "Off" position
when

Adjustment
of the torque
The machine is
provided with
a positive clutch. The
torque is adjusted
by changing the position of the clutch claws; the deeper the
gripping
of the
claws, the
higher the
torque.
In
order to
adjust the
claws loosen
securing
screw
(56),
then turn
screw (55).
Mor
eover, the torque is
dependent
on
the
pressure of
the
driver
against
the
screw.
5. Maintenance
Before carrying
out
any maintenance work always remember
to pull
out
the
plug.
Every
300 duty hours
blow or brush out
the
tool
with
special attention
to
carbon brush
holders and
insulated
p
arts
in order
to
guar
antee the
safety
given by
the protective insulation.
After
checking
the
carbon
brushes
m
ake
sure to
refit
them in their
original position and
check
that they
move
easily
in
their
holder
.
They
should
be replaced at the
latest when
they
have
worn dow
n
to
7
mm (1/4").
Please,
only use original
Fein carbon brushes.
After
fitting
new
brushes,
run
tool unloaded
for
about
15
minutes
to
allow
brushes
to bed
in.
One
pair
of spare
carbon
brushes
will
be
found in
the
cover
of
the handle; please,
do
not
forget
to
reorder them
in
time.
From
August 1970,
gear
and ball bearings are provided
with
