LOW OIL SHUTDOWN
A low oil shutdown switch is provided to protect the engine.
When engine oil level drops too low for proper engine operation,
the low oil shutdown switch causes the engine to shut off. If oil
level is low when attempting to start the engine, the low oil level
shutdown switch prevents the engine from starting. If engine
does not start, check oil level.
NOTE: It is important to keep the unit on a level surface. The oil
level shutdown switch can prevent the engine from starting even
if oil level is sufficient, when the unit is placed on an uneven
surface.
Pre-Operation (Continued)
Generator Operation
(FRONT PANEL SWITCHES MUST BE SET TO GENERATOR AND
120V / 240V POSITIONS)
1. All load devices and extension cords should use three prong
terminals. Refer to Table 2 for extension cord and cable size
requirements.
2. Allow the engine to run for 2-3 minutes before applying any
electrical loads.
3. The 120 volt duplex receptacles are rated for 20 amps and
may be used in any combination of 120 volt loads and also
with 240 volt loads through the 240 volt receptacles.
These duplex receptacles are of the Ground Fault Circuit
Interupter (GFCI) type. Ground Fault Circuit Interrupters
can significantly reduce the possibility of injury if an
electrical short occurs. The engine must be running and the
front panel switches set to supply power to the receptacles
before the GFCI’s can be reset.
A Ground Fault Circuit Interrupter may not be
effective if the unit is not grounded! Refer to the
section entitled Grounding for proper steps to ground the unit.
The 120 / 240 volt twist lock receptacle is rated for 30 amps
and may be used in any combination of 120 volt and 240
volt loads.
4. Individual receptacles should not be loaded beyond the
amperage rating.
5. Total combined load through any combination of
receptacles must not exceed the rated load limits of the unit.
Refer to the identification plate on the unit for amp and
wattage specifications.
6. Always shut off and remove loads before starting or shutting
off the engine.
7. When plugging multiple electrical load devices into the
receptacles, be sure to connect and activate the highest
power draw item first. Allow the engine to stabilize, then
connect and activate the next highest power draw device.
The smallest power draw device should be connected to the
receptacle and activated last.
NOTE: Power draw can be calculated by multiplying volts and
amps. The resulting number is wattage.
Never exceed the posted maximum wattage for the unit or any
individual receptacle. Refer to owner’s manuals and product tags
to determine the wattage of all electrical load devices.
If actual watt ratings are not available, the Power Usage Chart,
see Table 1, may be used as a general guideline.
Remember that devices which generate heat during operation
such as heaters, incandescent light bulbs, motors and hair
dryers have a higher power draw than devices which generate
little heat during operation such as florescent bulbs, radios, and
clocks.
Long power cords and extension cords also draw additional
power. Keep cords at minimum possible length.
Refer to Table 2 for maximum limits for lengths of extension
cords.
8. Circuit protection is provided by circuit breakers. The main
circuit breaker is a rocker type rated for 30 amps. This
is the maximum total current draw for all receptacles in
combination. A 20 amp circuit breaker supplies each of the
two duplex receptacles. The circuit breaker opens when
the load exceeds its maximum capacity or a short circuit
occurs. If the circuit breaker opens, perform the following
procedures to correct the problem:
a. Shut off and disconnect all electrical loads.
b. Attempt to determine the cause of the electrical
problem - overloading or short circuit.
c. Do not use any devices that have short circuits.
Avoid overloading the unit.
d. Press the circuit breaker pushbutton or rocker to reset
the circuit breaker.
Repeated cycling of the circuit breaker indicates
a problem and may cause damage to the unit or
load devices. Do not operate the unit if repeated cycling of the circuit
breaker occurs.
