OPERATING INSTRUCTIONS
GENERATOR CONTROL PANEL
Mounted on the generator control panel (Figure 1) are
the following features:
Figure 1 — Typical Control Panel
FUEL PRIMER
Before starting a cold engine (if it has not been start­
ed in more than two weeks), you must press this
switch to bring fuel from the tank to the fuel carbure­
tor. This rocker type switch springs back into its origi­
nal position when you release it.
START/STOP SWITCH
To crank and start the engine, hold this switch at its
START position. Release the switch when the engine
starts. To stop an operating engine, press and hold
the switch in its STOP position until the engine shuts
off. The switch center position is the RUN position.
FUSE
Protects the engine DC control circuit against electrical
overload. If the fuse element has melted open due to
overloading, the engine cannot be cranked. If you must
replace it, use only an identical replacement fuse.
CIRCUIT BREAKERS
Protects generator's AC output circuit against over­
load,
i.e., prevents unit from exceeding
wattage/amperage capacity.
HOUR METER
Indicates the time the engine-generator has operated,
in hours and tenths of hours. Use the hourmeter
along with the periodic maintenance schedule for your
generator set.
AUTOMATIC CHOKE (GASOUNE ONLY)
The engine is equipped with an automatic choke (not
shown) that consists of two main components —
choke solenoid and prechoke.
■ CHOKE SOLENOID (GASOLINE ONLY)
During engine cranking (start/stop switch at START),
a solid state control circuit board signals the choke
solenoid to actuate and cycle (choke on/choke off)
until engine starts. The choke solenoid thus opens
and closes the carburetor choke valve only when the
engine is cranking. When the engine starts, the
choke cycling stops.
■ PRECHOKE (GASOLINE ONLY)
The choke system also has a temperature sensitive
metal strip that adjusts the choke valve angle accord­
ing to ambient temperatures (i.e., in cofd ambient
temperatures the choke valve closes more). Once
the engine starts, an element heats the temperature-
sensitive strip to a normal operating condition, open­
ing the choke valve. This may take about 3 minutes
in cooler weather.
BEFORE STARTING THE ENGINE
IMPORTANT: INSTRUCTIONS AND INFORMATION
IN THIS MANUAL ASSUME THE GENERATOR HAS
BEEN
PROPERLY INSTALLED, CONNECTED,
SERVICED, TESTED AND ADJUSTED BY A QUALI­
FIED INSTALLATION TECHNICIAN OR INSTALLA­
TION CONTRACTOR.
■ INSTALLATION________________________
Generator installation must have been properly com­
pleted so it complies with all applicable codes, stan­
dards and regulations and with the manufacturer's
recommendations.
■ ENGINE LUBRICATION_________________
Have engine crankcase properly sen/iced with recom­
mended oil before starting. Refer to "Maintenance"
and "Specifications" sections for oil servicing proce­
dures and recommendations.
CAUTION: Any attempt to crank or start the
engine before you have properly serviced it with
the recommended oil may result in engine failure.
FUEL SUPPLY
The engine must have adequate supply of proper fuel
to operate. Before starting, check that sufficient fuel is
available.
NOTE: On some aasoline installations, the generator
engine may “share’^the vehicle’s gasoline fuel tank with
the vehicle engine. Some installations may provide
separate fuel tanks for generator and vehicle engine.
■ COOLING AND VENTILATING AIR
Air inlet and outlet openings in the generator compart­
ment must be open and unobstructed for continued
proper operation. Without sufficient cooling and venti­
lating air flow, the engine-generator quickly overheats,
which causes it to automatically shutdown. Overheating
could also damage the unit or your vehicle.
