The following are instructions for connection to the
power supply and the electrical ground.
This machine must be connected to the electrical ground to
protect the operator from electrical shock. The machine has
anapproved powercord withthree conductorsand aplug
with three terminals. Connect the plug to a receptacle that
has three holes and is connected to the electrical ground.
Thegreen (or greenand yellow) conductorin the cordis the
groundwire. Never connect thiswire to anyterminal other
thanthe groundpin terminal.
DANGER: Improper connection of
the equipment-grounding conductor can result
in 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.

electric circuit. Make sure you have the correct frequency
andvoltage beforeconnecting the powercord toan outlet.
The machine has a plug as shown in figureA.
WARNING: Always use this machine with anAC
three-conductor electrical system connected to
the electrical ground. Replace any worn, cut or
damaged cords. Replace any damaged plugs,
receptacles or connector bodies.
WARNING: Do not cut, remove, or break the
ground terminal. Do not try to fit a three-termi-
nal plug into a receptacle or connector body
that does not fit the plug, see your Authorized
N.A.C.E. Dealer to get an authorized person to
make the connection.
WARNING: Do not move the machine over an
electrical cord. Always lift the cord over the
machine.
EXTENSIONCORDS:
Useonly anapproved extension cordwith threeconductors,
a plug with three terminals and a connector body with three
holes. This machine has a power cord with wire size 18

Cet appareil est destiné à un circuit de 110 à 120 volts et 60
cycles. S'assurer que l'appareil est branché à une prise de
courant ayant la même configuration que la fiche. Cet
appareil est muni d'une fiche de mise à la terre semblable à
celle illustrée par la FigureA.
AVERTISSEMENT: Toujours employer cet
appareil avec un système électrique AC à trois
conducteurs, raccordé à la mise à la terre.
Remplacer tout cordon usé, coupé ou
endommagé. Remplacer toute fiche ou prise
endommagée.
AVERTISSEMENT: Ne pas couper, briser, ou
enlever la prise de terre. Ne pas chercher à
brancher la fiche à trois bornes, à une prise que
ne lul correspond pas. Si la prise ne correspond
pas à la fiche, contacter votre agent de vente
