Construction
This
two-speed
percussion
drill
is
an
electric
tool
of
Class
II
with
protective
insulation
without
earth
wire
and
in
accordance
with
VDE
regulations
0740.
The
protecti
ve
insulation
is
addi-
tional
to
the
normal
insulation
and
is
attained
by
the
shockproof
motor
housing
made
of
Polyamide
and
by
insulating
the
arma-
ture
shaft
against
the
gearing.
The
drill
is
tested
with
the
pre-
scribed
test
voltage
of 4000
V.
The
machine
is
radio
suppressed
according
to
radio
interference
degree
N.
It
is
supplied
with
a
two-core cable
without
earth
wire
and must
not
be
ear
thed
.
Type
DSk
736
for
low
tension (voltag
e 42
Volts)
is
of
the
same
design
but
without
double
insulation
and
not
radio
suppressed.
To
prevent
damage
to
the
insulation
no
additional
marking
pl
ates
and
signs
must
be
riveted
or
screwed
on the
housing.
We
recommend
the
use
of
transfers
only.

volt
age
marked
on
the rati
ng
plate.
The tool
can
be
plugged into
plain
or
safet
y
sockets
.
Switch
must
be

position
when
connecting!
Remove
the
grease
of
the
cones
before
dismantling
the

Maintenance
Before
carrying
out
any
maintenance work
always
remember
to
pull
out
the
plug.
To
guarantee
the
security
provided
by
the
double
insulation
clean
the
machine
regularly every
300
dut
y
hours. This
is
done
with a brush
or
by
blowi
ng
out
the
carbon
hold
ers and
the
insulated parts with dry pn
eumatic
air.
After
checking
the
carbon
brushes
make
sure
to refit t
hem
in their
original
position
and
check
that
they mo
ve
easily in the
ir
hold
er.

when
they
have
worn
down
to 7 mm
(1/4").
Please,
only
use
original
Fein
carbon
brushes.
After
fitting new
brushes
run
tool
unloaded
for
about
15
min~tes
to
allow
brushes
to
bed
in.
One
pair
of
spare
carbon
brushes
(21)
will

found
in
the
cover
of
the
handle,
please,
do
not
forget
to
reorder
them
in
time.
In

5. Lubrication
We
recommend
to
renew
the
gear. grease
after
300
duty
hours.
Please,
only
use
the
Fein
special
grease
FG
12.
For
ball
bearing
s
which
should
be
lubricated
after
approx.
900
duty
hours
we
re -
commend
our
ball
bearing
grease
FK
3.
The
ball
bearings
are
to
be
rinsed
in
clean
solvent
and
packed
with
new
grease.
The
space
between
inner
and
outer
ring
is
to
be
one
third filled
with
grease
in order to
prevent
that
the
bearings
do
not
over-
heat.
