Grounding Instructions
This jointer must be
grounded while in use to
protect the operator from electric shock.
In the event of a malfunction or breakdown,
grounding provides a path of least resistance for
electric current to reduce the risk of electric
shock. This tool is equipped with an electric cord
having an equipment-grounding conductor and a
grounding plug. The plug must be inserted into a
matching outlet that is properly installed and
grounded in accordance with all local codes and
ordinances.
Do not modify the plug provided. If it will not fit
the outlet, have the proper outlet installed by a
qualified electrician. Improper connection of the
equipment-grounding conductor can result in a
risk of electric shock. The conductor, with
insulation having an outer surface that is green
with or without yellow stripes, is the equipment-
grounding conductor. If repair or replacement of
the electric cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal.
Check with a qualified electrician or service
personnel if the grounding instructions are not
completely understood, or if in doubt as to
whether the tool is properly grounded. Use only
three wire extension cords that have three-prong
grounding plugs and three-pole receptacles that
accept the tool’s plug.
Repair or replace a damaged or worn cord
immediately.
115 Volt Operation
Referring to Figure 11:
As received from the factory, your Woodworking
Jointer is ready to run at 115-volt operation. This
Jointer, when wired for 115 volt, is intended for
use on a circuit that has an outlet and a plug that
looks like the one illustrated in (A). A temporary
adapter, which looks like the adapter shown in
(B), may be used to connect this plug to a two-
pole receptacle if a properly grounded outlet is
not available.
Figure 11
The temporary adapter should only be used until
a properly grounded outlet can be installed by a
qualified electrician. This adapter is not
applicable in Canada. The green colored rigid
ear, lug, or tab, extending from the adapter,
must be connected to a permanent ground such
as a properly grounded outlet box.
230 Volt Operation
Referring to Figure 12:
If 230V, single-phase operation is desired, the
following instructions must be followed:
1. Disconnect the machine from the power
source.
2. The Jointer motor has four numbered leads
that are factory connected for 115V
operation, as shown in (A). For 230V
operation reconnect the leads as shown in
(B). This is also shown in the diagrams on
pages 39 and 40.
3. The 115V attachment plug (C) supplied with
the Woodworking Jointer must be replaced
with a UL/CSA listed plug suitable for 230V
operation (D). Contact your local Authorized
Powermatic Service Center or qualified
electrician for proper procedures to install
the plug. The Woodworking Jointer must
comply with all local and national codes after
the 230-volt plug is installed.
4. The Jointer with a 230-volt plug should only
be connected to an outlet having the same
configuration as shown in (D). No adapter is
available nor should be used with the 230-
volt plug.
