MOTOR
Many

tools
will operate on
either
D.C.,
or
single phase
25 to 60
cycle
A.C.
current and voltage within plus or minus 5 percent of that shown
on
the
specificationplateon the tool. Several models, however,
are
designed
for
A.C.
current
only.
Refer to the specification plate on
your
tool for
proper
voltage
and
current
rating.
CAUTION: Do
not operate your tool on a
current on which the voltage
is not within correct limits. Donotoperatetools ratedA.C. only on
D.C.
current. To do so
may
seriously
damage the
tool.
EXTENSION
CORD SELECTION
If an extension cord is
used, make
sure the conductor size is large enough to
prevent
excessive
voltage drop which
will
cause
loss
of
power and possible
motor damage. A table of recommended extension cord sizes
will
be found
below. This
table is
based
on limiting
line
voltage drop to 5 volts (10 volts for
230
volts)
at
150%
of rated amperes.
If an extension cord is to be used
outdoors it
must be marked with the suffix
W-A
following
the cord
type
designation.
For
example
‐
SJTW-A
to
indicate
it is acceptable for outdoor
use.

OPERATING INSTRUCTIONS
FOREWORD
.
Oe
The
Porter-Cable
Model
550
Cutter®
is
designedto cut
es" wide
slots,
546"
to
¥4"
deep,
in material
that
is
54"
to
114"
thick and
at
least
Ye
wide.
An
adjustable guide
bushing
provides
accurate drill
alignment
for drilling
a %«
diameter
screw
hole.
The
cutter
should
be bolted or clamped to a workbench to
prevent
movement
during
operation.A 1"wide by 12"
longflange
Is
provided
on
each
side
of the machine for clamping; and four,
%e"
diameter
holes (72
by 10
pattern) are
provided
for bolting the
machine
to a workbench. In
some
applications it
may
be
more convenient
to
bolt
the
machine
to a
piece
of
plywood
and
then clamp the plywood
to
the
workbench.
