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.

SHOCK HAZARD. DO NOT EXPOSE THE MACHINE TO RAIN OR OPERATE THE MACHINE IN

DAMP LOCAT I O N S .

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, t h e

machine will have a grounding plug that looks like the plug

illustrated in F i g . 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. T h e

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. W h e n e v e r

t h e a d a p t e r i s used, it must be held in place with a metal

s c r e w.

N O T E : In Canada, the use of a temporary adapter is not

permitted by the Canadian Electric Code.

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

o r d i n a n c e s .

Do not modify the plug provided - if it will not fit the outlet,

have the proper outlet installed by a qualified electrician.

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

g r o u n d i n g i n s t r u c t i o n s a r e n o t completely understood, o r i f

i n d o u b t a s t o w h e t h e r t h e m a c h i n e is properly grounded.

Use only 3-wire extension cords that have 3-prong

grounding type plugs and matching 3-c o n d u c t o r

receptacles that accept the machine’s plug, as shown in

Fig. A .

Repair or replace damaged or worn cord immediately.

POWER CONNECTIONS

Your machine is wired for 120 Volt, 60 HZ alternating current. Before connecting the machine to the power source,

make sure the switch is in the “OFF” position.

GROUNDING INSTRUCTIONS
