The
angle
grinders
MSf
679
and
MSfa
679
are
electric
too
ls
of
Class
II
according
to
VDE
regulations
0740.
The
protective
insul-
ation
is
additional
to
the
normal
insulation
and
protects
the
ope-
rator
against
e
lectri
c
accidents
ca
us
ed
by
defective
normal
insul-
ation.
The
protective
insulation
is
attained
by
the
motor
housing
made
of
Polyamide-
shockproof
and
resistant
to
leakag
e
currents-
and
by
insulating
the
armature
against
the
pinion.
The
machine
is
supplied
with
a
two-core
cable
without
earth
wire
and
must
not
be
earthed.
The
dustproof
switch
is
mounted
in
the
handle.
The
machine
is
tested
with
the
prescribed
test
voltage
of
4000 V.
It
is
radio
suppressed
according
to
radio
interference
degree
VDE
0875.
The

Gears
are
l
ap
p
ed
for
accura
te
me
sh
ing;
both
parts
to
be
suppli
ed
as
pairs
only.
Gears
and
bearings
are
protected
against
dust
and
loss
of
grease.
Part
of
the
cooling
air
is
led
by
conductors
through
the
gearing
in
the
gear
h
ead
for
additional
cooling.
To
prevent
the
overbridging
of
the
insulation
no
ad
ditional
mark
i
ng
plates
and
signs
must
be
riveted
or
screwed
on
the
hou
sing.

hold
tool
in
such
a
position
that
the
grinding
wheel
works
under
an
angle
of
15-30

the
handle
is
screwed
into
the
right-hand
bore
of
the
housing
(seen
from
above)
in
order
to
prevent
the
grinding
dust
from
falling
into
the

Furthermore,
the
handle
should
be
screw
ed
into
the
righthand
bore
of
the
hou
