2. Construction
The High Frequency Grinder MSfo
870
is a high
capacity
tool
with
earth
cable
according
to the
VDE
regulations 0740.
For safety reasons the machine
is provided
with
an earth wire,
which is
yellow and green.
At
one
side it is
connected
to the
metal housing
of the
tool and at
the
other side
it
must be con-
nected
to the
protecting contact of
the
plug.
Machines for
42 Volts
(Class III)
have no
earthing
conductor.
Gears
are lapped for accurate meshing; both parts to be
supplied
as
pairs only. Gears
and
bearings are protected against dust
and
loss of
grease.
Part
of
the
cooling air is
led by
conducts
through the
gearing
in
the gear
head
for additional cooling.
3. Connection
and Operation
First check that
details on rating
plate
correspond to those of
the high frequency
supply.
To
avoid overloading
of the grinder
we
recommend
the installation
of a
safety switch.
Switch
must
be in the "Off" position when
connecting.
Check
that
the
tool rotates in direction marked
by arrow on the
machine, otherwise the tool may become
loose
.
To
check
rotation
switch on tool
briefly.
If
it does not follow arrow, reverse by
changing over two
leads
in the plug.

Please see instruction BE
22
for the high frequency
installation.
To
avoid overloading of the
grinder
we recommend
the
installa-
tion of
a
safety
switch
(see also separate
instruction
B
22).
Do not exceed the dimensions of grinding wheels stipulated.
When working with
crank
wheel hold
tool
in such
a
position
that the grinding wheel works under
an angle
of
15-
30
°.
For
cutting off
stone use
our wheel guard with adjustable
support.
4. Maintenance and Lubrication
The angle
grinder
requires
adequate mainten
ance.
Before star-
ting any maintenance work pull plug from
socket.
To
replace
cable
see
instructions.
of paragraph 5,
section
2.
After fitting new
cable check
connection
of conductor as well
as
of earth wire.
The
gearing should
be particularly well
greased.
Every 300
working
hours renew gear
grease.
Use
only
the prescribed
quality
FG
9.
To prevent
mixture
of
greases,
lubricate
the roller
bearings in the
gear
head
also
with
our special
grease
FG 9.
When
checking
or
renewing
the
grease, take out
screws
(48) on
bearing cap
(35)
.
Take
off
complete cap
with drive
shaft
(42)
and
remove old grease.
