120VOLT MACHINES
INSTRUCTIONSFORCONNECTION
TO THE POWER SUPPLY
ANDTHEELECTRICALGROUND
The machine must be connected to the electrical ground to
protect the operator from electric shock. The machine has
an approved power cord with three conductors and a plug
with three terminals. Connect the plug to a receptacle that
has three holes and is connected to the electrical ground.
For maximum protection against electric shock, use a cir-
cuit that is protected by a ground fault circuit interrupter.
Thegreen (or green andyellow)conductor in the cordisthe
ground wire. Never connect this wire to any terminal other
thanthe ground terminal.
This machine uses a 120 volt AC 60 cycle electrical circuit.
Make sure you have the correct frequency and voltage be-
fore connecting the power cord to an outlet. The machine
has a plug as shown in Figure 4. If a receptacle connected
tothe electricalground as shownin Figure4is notavailable,
haveone installedbyanelectrical contractor. Donot use an
adapter.
WARNING: To prevent possible electric shock,
protect the machine from rain. Keep
the machine in a dry building.
WARNING: To prevent possible electric shock,
always use a 3-wire electrical system
connected to the electrical ground.
Formaximum protectionagainst elec-
trical shock, use a circuit that is pro-
tected by a ground fault circuit inter-
rupter. Consult your electrical con-
tractor.
WARNING: Do not cut, remove or break the
ground pin. If the outlet does not fit
the plug, consult your electrical con-
tractor.
WARNING: Have worn, cut, or damaged cords
and plugs replaced by an authorized
service person.
EXTENSIONCORDS
Useonly anapproved extensioncordwith threeconductors,
aplug with three terminals,and a connector bodywiththree
holes. The machine has a power cord with wire size 16
AWG (AWG means American Wire Gauge).
WARNING: If you use an extension cord, use an
extension cord with minimum wire
size 16 AWG. Do not use an exten-
sion cord longer than 50 feet. Do not
join two extension cords.
