Construction
The
two
speed hand
drill
DSk
672
is
an electric tool of Class
II
with protective 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 b
e
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.
Type
DSk 772 for low tension (42
V)
is of
the same
design but
not radio suppressed.
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.

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
mov
e
easily in
their
holder.
After
fitting new
brushes,
run tool unloaded
for about
15 minutes
to
allow
brushes to b
ed
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 regular
intervals.
After
900 duty hours
the
machine should be completely
dis-
mantled
as
described under paragraph
6
and
all
parts should
