GROUNDING INSTRUCTIONS

86309230 CV71/2 02/19/08 2-3

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

malfunction 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 ordinances.

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 adaptor 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 adaptor 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 adaptor must be

connected to a permanent ground such as a

properly grounded outlet box cover. Whenever

the adaptor 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.
