INDEX
OF
PROBLEMS
AND
SOLUTIONS
8.1
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
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
can
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
are
needed
you
have
to
replace
all
the
cables
with
bigger
gage
rated
cables
for
the
length
and
amperage.

DISMOUNTING
TOOL
HOLDER
TO
CHANGING
V
‐
RINGS
AND
FELT
‐
RINGS
To
check
or
replace
the
buffers
and
the
elastic
elements,
the
tool
holders
have
to
be
dismounted.
You
will
need
a
13mm
deep
metric
socket
with
an
outside
diameter
of
no
more
than
3/4in
to
unscrew
the
four
bolts
(Fig.8.2.1)
and
remove
the
holder
(Fig.8.2.2)
When
the
tool
holder
is
dismounted,
you
can
change
the
sealers
(V
‐
Ring
and
Felt
‐
Ring).
By
loosening
four
Hex
cap
flange
bolts
(Fig.8.2.3)
the
adaptor
comes
loose.
Unscrew
the
six
screws
of
the
cap
(Fig.8.2.4)
holding
the
felt
‐
ring.
Take
out
the
Felt
‐
Ring,
adaptor
and
V
‐
Ring.
Mount
the
V
‐
Ring
with
the
smallest
lip
of
the
V
to
the
inside
(Fig.8.2.5)
‐
simply
push
the
V
‐
Ring
so
the
top
is
on
the
same
level
as
the
pulley
top
(Fig.8.2.6).
Then
take
the
adaptor
and
push
the
V
‐
Ring
down
with
the
adaptor
(Fig.8.2.7).
The
lowest
lip
of
the
V
‐
Ring
should
only
barely
touch
its
gliding
surface.
Mount
the
adaptor
and
the
Felt
‐
Ring
on
top
(Fig.8.2.7).
Close
the
sealers
with
the
cap
(Fig.8.2.8)
and
screw
the
bolts.
Always
use
the
original
bolts.
Do
not
push
the
V
‐
ring
down
with
fingers.
8.3
DISASSEMBLING
AND
MOUNTING
TOOL
HOLDER
TO
CHANGE
BUFFERS
AND
ELASTIC
ELEMENT
When
the
TOOL
HOLDER
is
disassembled
you
can
change
defective
parts
–
elastic
element,
buffers,
etc.
Lift
the
locking
pin
(Fig.8.3.1)
to
dismount
the
retaining
washer
(Fig.8.3.2).
Take
out
the
screws
on
the
buffers
and
the
nuts
of
the
elastic
element
(Fig.8.3.3;Fig.8.3.4).
Remove
the
elastic
element
from
the
QC
plate
(Fig.8.3.5).
While
the
holder
is
dismounted
(Fig.8.3.6;Fig.8.3.7)
clean
the
parts
and
replace
the
defective
with
new
ones.
Assemble
the
holder
with
new
buffers
with
new
screws
and
new
elastic
element.
Put
the
retaining
washer
(Fig.8.3.8)
and
push
the
locking
pin
(Fig.8.3.9).
This
will
prevent
the
fall
of
the
washer
when
mounting
the
holder
on
the
machine.
