four
readings
are
possible
:

OP.7
Proceed
with
the
OP
program.
It
is
recommended
that
the
tire
be
turned
over
on
the
rim
.OP.7
‐
II
Proceed
with
the
OP
program.
It
is
recommended
to
shift
the
tire
on
the
rim
(manual
rotation).
H0
Optimum
condition
has
been
achieved
and
cannot
be
improved.
H2
Silent
running
cannot
be
improved.
Press
STOP
(5)
to
exit.
However,
it
is
possible
to
readjust
the
tire
relative
to
the
rim
to
achieve
significant
weight
minimization
(i.e.:
smaller
balance
weights)
without
having
an
adverse
effect
on
silent
running.
Depending
on
the
readings,
there
are
several
possibilities
for
proceeding
with
the
program.
These
possibilities
are
described
below.
Reading
II
‐
OP.7(Fig.
5
‐
37).Turn
the
tire
over
on
the
rim
(the
left
display
bars
are
rotating).Option1:Turn
the
tire
over
on
the
rim
(normal
program)
.Read
just
the
wheel
according
to
the
left
direction
indicator
and
make
a
double
mark
on
the
left
side
of
the
tire
exactly
perpendicular
to
and
above
the
main
shaft.
Remove
the
wheel
from
the
machine.
Turn
the
tire
over
on
the
rim
and
readjust
until
the
double
mark
coincides
with
the
valve.
Clamp
the
wheel
on
the
balancer
and
read
just
it
so
that
the
valve
is
exactly
perpendicular
to
and
above
the
main
shaft.
Press
the
ENTER
key
(1)
to
acquire
the
valve
position.
Reading
OP.8
appears
(Fig.5
‐
34).Spin
the
wheel
(START).
If
balancing
optimization
(silent
running)
has
been
carried
out
correctly
(according
to
the
program
cycle),
after
the
check
run
the
machine
automatically
returns
to
the
type
of
weight
positioning
previously
selected
and
indicates
the
residual
dynamic
imbalance
on
the
wheel.
Balance
the
wheel
according
to
the
readings.
Both
optimization
and
balancing
are
accomplished.
Message
E9
means
that
at
least
on
error
occurred
during
the
optimization
cycle.
Press
the
STOP
key
(5)
to
exit
the
optimization
program
and
repeat
optimization
if
necessary.
