FOREWORD
This technical
manual
has
been
prepared
to
guide
you
in the maintenance
of
your
new
UNION
SPECIAL
machine. Careful
attention
to the
instructions
for
operating
and
adjusting these machines will enable
you
to maintain the
superior
performance
and
re-
liability
designed
and
built
into
every
UNION
SPECIAL
machine.
The
Adjusting
Instructions
portion
of
this
manual
explains in
detail
the proper
setting
for
each
of
the
components
related
to forming the
stitch
and
completing the
functions
of
the machine.
The
text
of
the Adjustments
is
divided
into
two
sections -
Check
and
Procedure.
The
Check
depicts conditions
when
the
parts
are
adjusted cor-
rectly.
The
Procedure
is
given to explain the proper steps to
be
taken in the event
adjustments are required. Figures
are
used to
illustrate
the adjustments using
refer-
ence
letters
to
point
out
specific
items discussed.
Adjustments are presented in
sequr:mce
so
that
a logical progression
is
accom-
pli
shed.
Some
adjustments performed out of sequence
may
have
an
adverse
effect
on
the
function of
other
related
parts.
Implementation
of
preventative maintenance procedures
can
bring about
signifi-
cant
improvements
in operator
productivity
by
avoiding
costly
equipment breakdowns.
Whenever
it
becomes
necessary to
make
repairs
or
replace
parts
on
your machine,
be
sure to
insist
on
genuine
UNION
SPECIAL
Repair
Parts.
These
parts
are
designed speci-
fically
for
your
machine
and
manufactured with utmost precision to assure long
last-
ing
service.
To
simplify
identification
of
repair
parts,
the
mechanisms
are
illustrated
by
exploded views.
These
illustrations
will
usually
be
shown
in conjunction with a
KEY
VIEW
which
presents the
mechanisms
of
the
machine
assembled.
The
specific
parts
illustrated
on
this
page
