Generac Power Systems Q-70G Series User Manual

• 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 en¬
gine may "share" the vehicle’s gasoline fuel tank
with vehicle engine. Some installations may pro¬
vide separate fuel tanks for generator and vehicle
engine.
• Cooling and Ventilating Air: Air inlet and outlet
openings in the generator compartment must be
open and unobstructed for continued proper oper¬
ation. Without sufficient cooling and ventilating air
flow, the engine-generator quickly overheats which
causes it to quickly shutdown. Overheating could
also damage the unit or your vehicle.
• Engine Exhaust Gases: Before starting the gen¬
erator engine, you should be sure there is no way
for exhaust gases to enter the vehicle interior and
endangering people or animals. Close windows,
doors and other openings in the vehicle that, if open,
might permit exhaust gases to enter the vehicle.
DANGER: THE GENERATOR ENGINE GIVES
OFF DEADLY CARBON MONOXIDE GAS
THROUGH ITS EXHAUST SYSTEM. THIS DAN¬
GEROUS GAS, IF BREATHED IN SUFFICIENT
CONCENTRATIONS, CAN CAUSE UNCON¬
SCIOUSNESS OR EVEN DEATH. DO NOT OPER¬
ATE THE GENERATOR IF ITS EXHAUST SYSTEM
IS LEAKING OR HAS BEEN DAMAGED. SYMP¬
TOMS OF CARBON MONOXIDE POISONING ARE
(A) INABILITY TO THINK COHERENTLY, (B)
VOMITTING, (C) TWITCHING MUSCLES, (D)
THROBBING TEMPLES, (E) DIZZINESS, (F)
HEADACHE, (G) WEAKNESS AND SLEEPINESS.
IF YOU FEEL ANY OF THESE SYMPTOMS, MOVE
INTO FRESH AIR IMMEDIATELY. IF SYMPTOMS
PERSIST, GET MEDICAL HELP. _
STARTING
IMPORTANT: Read the vehicle manufacturer's instruc¬
tions. The owner/operator should become familiar with
the vehicle in which this generator is installed. Differ¬
ences exist between vehicles. For example, some ve¬
hicles may use a transfer switch to isolate dockside
power from the generator, while other vehicles may use
an isolating receptacle. Some vehicles may be
equipped with a DC converter which allows the gener¬
ator to power certain DC lighting and other DC loads.
To crank and start the generator engine, proceed as
follows:
1. T urn OFF electrical loads, using whatever means
provided in your vehicle (such as a main line circuit
breaker or transfer switch.
NOTE: If you start the engine with start/stop switch on
the generator control panel, turn OFF loads by setting
the panel's main breakers to their "OFF" or “OPEN"
positions. Electrical load circuits will be turned ON after
the generator has started, stabilized and warmed up.
2. If you have not started the engine in more than two
weeks, press the Fuel Pump Primer switch and hold
it for about 30 seconds to activate the automatic
shut-off function. However, if the engine is warm,
skip Step 2.
3. To crank and start the engine, hold the start/stop
switch at START. Release the switch when the
engine starts.
CAUTION: If the engine does not start after it has
been cranking for 15 seconds, release the start/stop
switch and try again. Holding the switch for longer
than 15 seconds can damage the starter motor.
4. Let the engine run at no-load for a few minutes to
stabilize and warm up the engine.
5. Turn ON electrical loads, using whatever means
provided (such as a main circuit breaker or transfer
switch).
STOPPING THE GENERATOR
1. Turn OFF all electrical loads, using whatever
means provided (such a main circuit breaker or
transfer switch).
2. Let the generator run at no-load for a few minutes,
to stabilize internal engine-generator tempera¬
tures.
3. Press STOP on the start/stop switch. The engine
will come to complete stop.
APPLYING LOADS TO GENERATOR
When applying electrical loads to the generator, ob¬
serve these guidelines:
• Before applying electrical loads, let the generator
stabilize and warm up for a minute or two.
• DO NOT overload the generator.
Letting Engine Stabilize: The generator supplies cor¬
rect rated frequency and voltage only at the proper
governed speed. Some electrical appliances may be
extremely sensitive to voltage and frequency. Incorrect
frequencies and/or voltages can damage those appli¬
ances.
If electrical loads are applied at reduced operating
speeds, such loads imposed on the engine when suffi¬
cient power is not available may shorten engine life.
Never turn ON electrical loads until after the generator
engine has started and stabilized ON-speed.
