Safety

Grounding Instructions

THIS PRODUCT IS FOR COMMERCIAL

USE ONLY.

ELECTRICAL:

In the USA this machine operates on a standard 15

amp 115V, 60 hz, A.C. power circuit. The amp, hertz,

and voltage are listed on the data label found on each

machine. Using voltages above or below those

indicated on the data label will cause serious damage

to the motors.

EXTENSION CORDS:

If an extension cord is used, the wire size must be at

least one size larger than the power cord on the

machine, and must be limited to 50 feet (15.5m) in

length.

GROUNDING INSTRUCTIONS:

This appliance must be grounded. If it should malfunc-

tion or break down, grounding provides a path of least

resistance for electric current to reduce the risk of

electric shock. This appliance is equipped with a cord

having an equipment-grounding conductor and

grounding plug. The plug must be inserted into an

appropriate outlet that is properly installed and

grounded in accordance with all local codes and ordi-

nances.

This appliance is for use on a nominal 120-volt circuit,

and has a grounded plug that looks like the plug in "Fig.

A". A temporary adapter that looks like the adaptor in

"Fig. C" may be used to connect this plug to a 2-pole

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 (Fig. A)

can be installed by a qualified electrician. The green

colored rigid ear, lug, or wire extending from the

adapter must be connected to a permanent ground

such as a properly grounded outlet box cover.

Whenever the adapter is used, it must be held in place

by a metal screw.

Improper connection of the equipment-grounding

conductor can result in a risk of electric shock.

Check with a qualified electrician or service person

if you are in doubt as to whether the outlet is

properly grounded. Do not modify the plug

provided with the appliance - if it will not fit the

outlet, have a proper outlet installed by a qualified

electrician.
