Extension cords
The use of an extension cord is not
recommended for the PJ882 Jointer. But if one
is necessary, make sure the cord rating is
suitable for the amperage listed on the
machine’s motor plate. An undersized cord will
cause a drop in line voltage resulting in loss of
power and overheating.

Use the chart in Figure 8 as a general guide in
choosing the correct size cord. If in doubt, use
the next heavier gauge. The smaller the gauge
number, the heavier the cord.

model of the PJ-882 Jointer is designed to run
on 230 volt power only.

If the Jointer is to be hard-wired, make sure the
fuses have been removed or the breakers have
been tripped in the circuit to which the Jointer
will be connected. Place a warning placard on
the fuse holder/circuit breaker to prevent it being
turned on while the machine is being wired.

The Jointer with a 230 volt plug should only be
connected to an outlet having the same
configuration. No adapter is available or should
be used with the 230 volt plug.

It is recommended that the three phase jointer,
when operated at 230 volts, be connected to a
dedicated, minimum 20 amp circuit with a 20
amp circuit breaker or time delay fuse. When
operated at 460 volts, connect the jointer to a
dedicated, minimum 15 amp circuit with 15 amp
circuit breaker or time delay fuse. Local codes
take precedence over recommendations.
