1.
Since
these

are
precisely
factory
adjusted,
in
general,
they
should
not
be
re-adjusted.
If
it is

required,
a

2.
To
facilitate
adjustment,
the

should
be
placed
in
a
vertical
position.
3.
For
the

mounted
on
both
left

use
the
same

Before
all
the
following

perform
next
instructions
in
order
to
activate
