INDEX
OF
PROBLEMS
AND
SOLUTIONS
9.1
REPLACING
POWER
CORD
AND
PLUGS
When
replacing
the
power
cord
or
plugs
always
use
cords
and
plugs
with
specifications
as
the
original
ones.
Never
use
lower
quality
or
different
type
cord
and
plugs.
In
addition,
take
into
consideration
is
the
distance
of
the
appliance
from
the
electrical
source.
The
greater
the
distance,
the
greater
the
resistance
and
the
less
current
that
will
be
available
at
the
other
end,
there
will
be
a
voltage
drop
and
the
inverter
will
sign
alarm
mode.
This
also
happen
if
several
machines
are
working
on
the
same
line
or
when
the
generator
is
underrated.
In
general
our
standard
power
cable
can
be
doubled
in
length,
if
longer
lengths
needed
you
have
replace
all
the
cables
with
cables
with
bigger
gage
rated
for
the
length
and
amperage.

DISMOUNTING
AND
MOUNTING
TOOL
HOLDER
TO
CHANGE
BUFFERS
AND
SPIDERS,
CHANGING
V
‐
RINGS
AND
FELT
‐
RINGS
To
check
or
replace
the
buffers
and
the
spiders,
the
tool
holders
have
to
be
dismounted.
Remove
the
countersunk
screws
on
top
of
the
buffer
(Fig.9.2.1).
Take
the
disc
off
(Fig.9.2.2),
the
spider
can
be
removed
or
replaced
(Fig.9.2.3).
By
loosening
four
Hex
cap
bolts
(Fig.9.2.4),
the
disc
comes
loose
(Fig.9.2.5)
and
the
buffers
can
be
replaced
(Fig.9.2.6).
Attention,
by
mounting
use
always
the
“blue”
thread
locking
adhesive,
except
on
the
bolts
to
lock
the
buffers
(Fig.9.2.5).
Always
use
the
original
bolts.
Depending
on
the
number
(3,
4
or
6)
of
buffers,
the
holder
can
be
more
flexible
or
rigid.
When
the
tool
holder
is
dismounted,
you
can
change
the
sealers
(V
‐
Ring
and
Felt
‐
Ring).
Take
out
Felt
‐
Ring,
Adaptor
and
V
‐
Ring.
Before
mounting
check
on
which
side
the
adaptor
is
fitting,
remember
the
correct
side.
Mount
the
V
‐
Ring
with
the
smallest
lip
of
the
V
to
inside
(Fig.9.2.7)
just
push
the
V
‐
ring
so
the
top
is
on
the
same
level
as
the
pulley
top
(Fig.9.2.8).
Then
take
the
adaptor
in
the
correct
way
and
push
the
V
‐
Ring
down
with
the
adaptor
(Fig.9.2.9).
The
lowest
lip
of
the
V
‐
Ring
should
only
barely
touch
its
gliding
surface;
also
never
push
the
V
‐
Ring
down
with
fingers.
Mount
now
the
Felt
‐
ring
on
top
(Fig.9.2.10).
Close
the
sealers
with
the
cap
(Fig.9.2.11).
