GENERATOR CONTROL PANEL
Mounted on the generator control panel (Figure 2) are
the following features:
Figure 2- Typical Control Panel
• FUEL PRIMER
Before starting a cold engine (it has not been started
in more than two weeks), you must press this switch
to bring fuel from the tank to the fuel pump. This rock-
er type switch springs back into its original 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 BREAKER
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
The engine is equipped with an automatic choke that
consists of two main components - choke solenoid
and prechoke.
OPERATING INSTRUCTIONS
• CHOKE SOLENOID
During engine cranking (start/stop switch at START),
a solid state choke module 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 crank-
ing. When the engine starts, the choke cycling stops.
• PRECHOKE
The choke system also has a temperature sensitive
metal strip that adjusts the choke valve angle accord-
ing to ambient temperatures (i.e., in cold 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 OF 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 serviced 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 installations, the generator engine
may "share" the vehicle's gasoline fuel tank with the
vehicle engine. Some installations may provide sepa-
rate 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.
