Generac Power Systems Q-70G Series User Manual

OPERATING INSTRUCTIONS
GENERATOR CONTROL PANEL
Mounted on the generator control panel (Figure 2) are
the following features:
• Fuel Pump 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 rocker 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, place the switch in its STOP position. The
switch center position is the RUN position.
• 15 amp Fuse: Protects the engine DC control
circuit against electrical overload. If the fuse ele¬
ment has melted open due to overloading, the en¬
gine cannot be cranked. If you must replace it, use
only an identical 15 amp replacement fuse.
• Line Breakers: Protects generator’s AC output
circuit against overload, i.e., prevents unit from
exceeding wattage/amperage capacity. NP-50G
has one 20 amp breaker and one 30 amp breaker.
NOTE: If your "Q" Series generator has been recon¬
nected for dual voltage AC output (120/240 volts), you
can install line breakers having an amperage rating that
is different than stated above. The replacement line
breakers consist of two separate breakers with a con¬
necting piece between the breaker handles (so that both
breakers will operate at the same time). If the unit is
reconnected for dual voltage, it is no longer RVIA listed.
OPTIONAL REMOTE START/STOP PANEL
Optional remote mounted panels are available which
permit you to crank and start the generator from any
convenient location in the industrial vehicle. Figure 3
shows the Model 9042 remote panel which includes (a)
start/stop switch and (b) a generator run lamp.
You can also order Model 9043, a remote panel which
includes the (a) start/stop switch, (b) the generator run
lamp and (c) an hourmeter. The hourmeter provides a
continuous indication of engine-generator operating
time. Use the hourmeter for checking off periodic main¬
tenance requirements on the unit.

AUTOMATIC CHOKE
The engine is equipped with an automatic choke that
consists of two main components—choke solenoid and
prechoke.
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 cranking. When the engine starts,
the choke cycling stops.
Prechoke: The choke system also has a temperature
sensjtive metal strip that adjusts the choke valve angle
according to ambient temperatures (i.e. in cold ambient
temperatures the choke valve closes more). Once the
engine starts, an element heats the temperature-sensi¬
tive strip to a normal operating condition, opening 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, SER¬
VICED, TESTED AND ADJUSTED BY A QUALIFIED
INSTALLATION TECHNICIAN OR INSTALLATION
CONTRACTOR.
• Installation: Generator installation must have
been properly completed so it complies with all
applicable codes, standards and regulations and
with the manufacturer’s recommendations.
• Engine Lubrication: Have engine crankcase
properly serviced with recommended oil before
starting. Refer to "Maintenance'' and "Specifica¬
tions” sections for oil servicing procedures and rec¬
ommendations.
CAUTION: Any attempt to crank or start the engine
before you have properly serviced it with the recom¬
mended oil will result in an engine failure.
