POWER CONNECTIONS

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
motor to the power line, make sure the switch 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 motor.

WARNING: DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN DAMP LOCATIONS.

MOTOR SPECIFICATIONS

Your machine is wired for 115 volt, 60 HZ alternating current. Before connecting the machine to the power source,
make sure the switch is in the “OFF” position. 

GROUNDING INSTRUCTIONS

WARNING: THIS MACHINE MUST BE GROUNDED WHILE IN USE TO PROTECT THE OPERATOR FROM
ELECTRIC SHOCK.   

2. Grounded, cord-connected machines intended for use
on a supply circuit having a nominal rating less than 150
volts:

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. A temporary adapter, which looks like
the adapter illustrated in Fig. B, may be used to connect
this plug to a matching 2-conductor receptacle as shown
in Fig. B if a properly grounded outlet is not available. The
temporary adapter should be used only until a properly
grounded outlet can be installed by a qualified electrician.
The green-colored rigid ear, lug, and the like, extending
from the adapter must be connected to a permanent
ground such as a properly grounded outlet box. Whenever
the adapter is used, it must be held in place with a metal
screw.

NOTE: In Canada, the use of a temporary adapter is not
permitted by the Canadian Electric Code.

WARNING: IN ALL CASES, MAKE CERTAIN THE 

RECEPTACLE IN QUESTION IS PROPERLY

G R O U N D E D . I F Y O U A R E N O T S U R E H AV E A
QUALIFIED ELECTRICIAN CHECK THE RECEPTACLE.

1. All grounded, cord-connected machines: 

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 machine is
equipped with an electric cord having an equipment-
grounding conductor and a grounding plug. The plug must
be plugged 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 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 machine is properly grounded.

Use only 3-wire extension cords that have 3-prong grounding
type plugs and matching 3-conductor receptacles that
accept the machine’s plug, as shown in Fig. A.

Repair or replace damaged or worn cord immediately.
