Safety
rules
for
the
operation
of
the
floor
grinder
Attention!
The
ALPHA
®
floor
grinders
are
constructed
according
to
existing
safety
rules
and
regulations.
These
technical
precautions
should
not
be
removed
or
changed
under
any
circumstances.
While
operating
the
machines
the
following
points
should
also
be
kept
in
mind:
1.
The
grinders
should
always
be
operated
with
all
safety
covers
and
technical
precautions.
2.
During
transport,
cleaning,
repair
or
maintenance
the
grinder
must
be
disconnected
from
the
mains.
That
also
applies
to
the
changing
of
tools.
3.
The
safety
ring
(Diagram
No.
17)
can
only
be
removed
while
operating
the
machine
directly
against
the
wall.
While
operating
the
machine
without
the
safety
ring
dust
can
be
generated.
In
this
case
the
operator
must
wear
a
mask.
In
all
other
cases
the
grinder
must
be
operated
with
the
safety
ring.
4.
The
operator
should
never
leave
the
machine
unattended
during
operation.
5.
Before
leaving
the
machine
all
rotary
parts
should
be
brought
to
a
stand
still.
Electric
models
must
be
disconnected
from
the
mains.
Make
sure
that
the
machine
cannot
roll
or
move
by
itself.
6.
After
any
maintenance
and
adjustment
all
safety
covers
must
be
reattached.
7.
Ear
protectors
must
be
worn.
8.
Eye
protectors
must
be
worn.
9.
Safety
shoes
with
steel
caps
must
be
worn.
10.
In
the
event
of
a
large
amount
of
dust
during
operation,
connect
a
dust
collector
to
the
grinder.
11.
Depending
on
the
floor
(floor
coating)
grinding
can
produce
gases.
The
operator
must
be
held
responsible
if
these
generated
gases
are
dangerous
and
if
protection
is
necessary.
Grinding
floors
containing
asbestos
is
especially
dangerous
and
can
cause
health
problems.
Special
masks
must
be
worn
which
keep
the
breathing
air
clean.
A
dust
collector
must
be
used
and
should
be
equipped
with
filters
suitable
for
asbestos
dust.
