A separate electrical circuit should be used for your machines. This circuit should not be less than #12 wire and should
be protected with a 20 Amp time lag fuse. If an extension cord is used, use only 3-wire extension cords which have 3-
prong grounding type plugs and matching receptacle which will accept the machine’s plug. Before connecting the
machine to the power line, make sure the switch (s) is in the “OFF” position and be sure that the electric current is of
the same characteristics as indicated on the machine. All line connections should make good contact. Running on low
voltage will damage the machine.
DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.
3. Grounded, cord-connected machines intended for
use on a supply circuit having a nominal rating
between 150 - 250 volts, inclusive:
If the machine is intended for use on a circuit that has an
outlet that looks like the one illustrated in Fig. A, the
machine will have a grounding plug that looks like the
plug illustrated in Fig. A. Make sure the machine is
connected to an outlet having the same configuration as
the plug. No adapter is available or should be used with
this machine. If the machine must be re-connected for
use on a different type of electric circuit, the re-
connection should be made by qualified service
personnel; and after re-connection, the machine should
comply with all local codes and ordinances.

POWER CONNECTIONS
MOTOR SPECIFICATIONS
The motor supplied with your 15” Planer is either a three horsepower, single phase motor, or a three horsepower, three
phase motor. The three horsepower, single phase motor is wired for 230 Volt operation and the three horsepower, three
phase motor is wired for 200-220 Volt operation. Before connecting the machine to the power source, make sure the
switch is in the “OFF” position.
GROUNDING INSTRUCTIONS
THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.

230 VOLT, SINGLE PHASE OPERATION
If the motor on your machine is wired for 230 Volt, Single
Phase operation, the power cord from the motor is
equipped with a plug that has two flat, current-carrying
prongs in tandem, and one round or “U”-shaped longer
ground prong, as shown in Fig. A. This plug is used only
with the proper mating 3-conductor grounding type
receptacle as shown.
When the three prong plug on your machine is plugged
into a grounded 3-conductor receptacle, as shown in
Fig. A, the long ground prong on the plug contacts first
so that the machine is properly grounded before
electricity reaches it.

4. Permanently connected machines:
If the machine is intended to be permanently connected,
the machine should be connected to a grounded metal
permanent wiring system, or to a system having an
equipment-grounding conductor.
