CORD SETS AND CONNECTOR PLUGS
120 VOLTS DUPLEX RECEPTACLE
Use only high quality, well-insulated, extension cords
with the 120-volt =duplex" type electrical receptacles
(Fig. 1). All cord sets used should be rated 125 volts at
15 a-c amps or greater for most electrical devices.
Keep extension cords as short as possible, preferably
less than 15 feet long to prevent voltage drop and wires
from overheating.

GROUNDING THE GENERATOR
The National Electrical Code requires that the frame and
external electrically conductive parts of this generator be
properly connected to an approved earth ground. Local
electrical codes may also require proper grounding of the
unit. For that purpose, a GROUNDING WING NUT is
provided on the base of the cradle (Fig. 3). Generally,
connecting a No. 12 AWG (American Wire Gauge)
stranded copper wire to the grounding lug and to an earth-
driven copper or brass grounding rod (electrode) provides
adequate protection against electrical shock. Be sure to
keep ground wire attached when you connect electrode.
However, local codes mayvary widely. Consult witha local
electrician for grounding requirements inyourarea. Proper
grounding of generator will help prevent electrical shock in
the event of a ground fault condition in the generator or in
connected electrical devices. Proper grounding also helps
dissipate static electricity, which often builds up in un-
grounded devices.

BEFORE STARTING ENGINE
ADD OIL:
Place generator on a level surface and remove one of
the yellow Oil Fill Caps (Fig. 4) and add engine oil until
level is at point of overflowing. Check engine oil level
before startingeach time thereafter. Ifoillevel is below
point of overflowing, fill to proper level. The recom-
mended oils include (during summer months) SAE 30
oil. SAE 10W-30 is an acceptable substitute. During
winter months use SAE 5W-20 or 5W-30. DO NOT
USE 10W-40. Crankcase oil capacity is about 620ml
or 21 fluid ounces.
FIG. 4
CAUTION: ANY AI-rEMPT TO CRANK OR START

• When engine starts, open choke gradually.
CONNECTING ELECTRICAL LOADS
Letengine stabilize and warm up for about five minutes
after starting.
Plug in and turn on the desired 120 or 240 volts, single
phase, 60 Hertz, a-c electrical loads.
DO NOT connect 240 volts to 120 volts duplex recep-
tacles.
DO NOT connect 3-phase loads to panel receptacles.
DO NOT connect any 50 Hz loads to the generator.
Add upthe rated watts of all lights,tool, appliance and
motor loads you are powering at one time. This total
shouldNOT be greater than (a) generator"_rated watt-
age capacity or (b) circuit breaker rating of the recep-
tacle supplying the power.
STOPPING THE ENGINE
• Disconnect all electrical loads and let engine run at
no-load for about five minutes to stablize intemal tem-
peratures of engine and generator.
• Turn off the engine by moving the Run/Stop switch to
STOP position.

OPERATION
LOW OIL PRESSURE SHUTDOWN SYSTEM
The engine isequipped with a low oil pressure sensor that
shuts down the engine automatically when the oil pressure
drops below 6 psi. If the engine shuts down by itself and
the fuel tank has enough gasoline, check engine oil level.
INITIAL STARTUP
A delay built inthe shutdown system allows oil pressure to
buildduringstarting. The delay allows the engine to runfor
about 10 seconds before sensing oil pressure.
SENSING LOW PRESSURE
If the system senses low oilpressure during operation, the
engine shuts down. As the system shuts down, the low oil
light comes ON. However, once the engine has stopped
rotating, this lightwill go OFF.
RESTARTING
Ifyou try to restart the engine within 5 seconds after it shuts
down, the engine may NOT start. The system needs 5 to
10 seconds to reset.
If you do restart the engine after such a shutdown and
have not corrected the low oil pressure, the engine
runs for about 10 seconds as described above and then
stops.
DON'T OVERLOAD THE GENERATOR
Overloading a generator in excess of its rated wattage
capacity can result in damage to generator and to con-
nected electrical devices. Observe the following, to prevent
overloading the unit:
• Add up the total wattage of all electrical devices to be
connected at one time. This total should NOT be
greater than the generator's wattage capacity.
• The rated wattage of lights can be taken from light
bulbs. The rated wattage of tools, appliances and
motors can usually be found on a data plate or decal
affixed to the device.
• If the appliance, tool or motor does not give wattage,
mulitply 120 volts times ampere rating to determine
watts (volts x amps = watts).
• Some electric motors, such as inductiontypes, require
about two-and-a-half times more watts of power for
startingthan for running. This surge of power lasts for
onlya few seconds when startingsuch motors. Be sure
you allow for this high starting wattage when selecting
electrical devices to connect to your generator. First
figure the watts needed to start largest motor. Add to
that figure runningwatts of allother connected loads.
• The GUIDE below is provided to assist you in deter-
mining how many items your generator can operate at
one time.
