2. Construction
The hand drill
ASk
658 is
an electric
tool
of Class
II
with
pro-
tective insulation according to VDE regulations 0740. The
protective
insulation is
additional
to
the
normal
insulation and
separates all accessible parts of
the
metal casing from all
internal
parts
liable
to
become
live.
The
machine must
not
be
earthed and must
be
connected with
a
two-core
cable without earth wire.
The drill is tested
with
the prescribed
test voltage of 4000 V.
The machine is radio
suppressed according
to radio interference
degree
N.
To prevent the
overbridging of
the insulation no
additional
marking plates
and
signs must be riveted or
screwed o~
the
housing. We recommend the use of transfers
only.
Type
ASk 758
for low tension
(42
Volts) is
of
the
same
design,
but
not
radio
suppressed.
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.

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
parts in order
to
guarantee the safety given
by the
protective
insulation.
After checking
the
carbon
brushes.
make sure to
refit
them in
their
original position and check
that
they·
move
easily
in their
holder.
After
fitting new brushes, run tool unloaded
for about
15 minutes to
allow
brushes
to
bed
in.
Worn carbon
brushes
automatically switch off
the machine
after
reaching
their minimum length.
Please, only
use
original
Fein
carbon
brushes.
In
order to prevent accidents check cable and connections
at
both
sides at
r egular intervals.
After 900 duty hours the machine
should
be
completely
dis-
mantled as
described under paragraph
6
and all parts should
be
thoroughly
cleaned. Rinse
ball bearings and gears in clean sol-
vent and
pack
with fresh
grease
as
per paragraph
5.
Please be sure that all electric and plastic parts only cleaned
dry.
