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 in
this section. 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 or W following the cord type designation. For example – SJTW-A to indicate it
is acceptable for outdoor use.

Nameplate Ampere Rating
MOTOR
Many Porter-Cable 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 specification plate on 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.
Do not operate your tool on a current on which the
voltage is not within correct limits. Do not operate tools rated A.C.
only on D.C. current. To do so may seriously damage the tool.
