ENGINE EXHAUST GAS
Before starting the generator 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 vehi­
cle 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 DANGER­
OUS GAS, IF BREATHED IN SUFFICIENT CONCEN­
TRATIONS, CAN CAUSE UNCONSCIOUSNESS OR
EVEN DEATH. DO NOT OPERATE THE GENERA­
TOR IF ITS EXHAUST SYSTEM IS LEAKING OR
HAS BEEN DAMAGED. SYMPTOMS OF CARBON
MONOXIDE POISONING ARE (A) INABILITY TO
THINK COHERENTLY, (B) VOMITING, (C) TWITCH­
ING MUSCLES, (D) THROBBING TEMPLES, (E)
DIZZINESS, (F) HEADACHE, (G) WEAKNESS AND
SLEEPINESS. IF YOU FEEL ANY OF THESE SYMP­
TOMS, MOVE INTO FRESH AIR IMMEDIATELY. IF
SYMPTOMS PERSIST, GET MEDICAL HELP.
STARTING
IMPORTANT: Read the vehicle manufacturer’s
instructions. The owner/operator should become
familiar with the vehicle in which this generator is
installed. Differences exist between vehicles. For
example, some vehicles 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 generator to power certain DC lighting and
other DC loads.
To crank and start the generator engine, proceed as
follows;
1. Turn OFF electrical loads, using whatever means provid­
ed in your vehicle (such as a main line circuit breaker or
transfer switch.
NOTE: If you start the engine with the start/stop
switch on the generator control panel, turn OFF loads
by setting the panel’s main breaker to the “OFF” or
“OPEN” position. Electrical load circuits will be turned
ON after the generator has started, stabilized and
warmed up.
NOTE: You only need to use the fuel primer during
the initial startup, after the unit has not been used for
an extended period of time (two weeks) or the fuel
line has been disconnected. The primer is used to
prime the fuel pump and carburetor.
2. 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 may damage the starter motor.
3. Let the engine run at no-load for a few minutes to stabi­
lize and warm up the engine.
4. Turn ON electrical loads, using whatever means provided
(such as a main circuit breaker or transfer switch).
NOTE: If you start a warm generator engine, you
may press the start switch only slightly to engage the
ignition system. However, you should press and hold
the starter switch for a minimum of two (2) seconds to
energize the field boost system. If you start the
engine without energizing the field boost system, the
generator produces no AC output.
STOPPING THE GENERATOR
1. Turn OFF all electrical loads, using whatever means pro­
vided (such a main circuit breaker or transfer switch).
2. Let the generator run at no-load for a few minutes, to sta­
bilize internal engine-generator temperatures.
3. Place start/stop switch in its STOP position.
APPLYING LOADS TO GENERATOR
When applying electrical loads to the generator,
observe 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 correct 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 appliances.
If electrical loads are applied at reduced operating
speeds, such loads imposed on the engine when suf­
ficient power is not available may shorten engine life.
Never turn ON electrical loads until after the genera­
tor engine has started and stabilized ON-speed.
ATTENTION REQUIRED AFTER
SUBMERSION
If the motor home generator has been submerged in
water, it must NOT be started or operated. Following
any submersion in water, have an authorized Generac
Service Facility thoroughly clean and dry the generator.
OPERATION IN HIGH GRASS OR BRUSH
Never operate the generator while the vehicle is
parked in high grass, weeds, brush or leaves. Such
materials can ignite and burn from the heat of the
exhaust system. The generator exhaust system
becomes extremely hot during operation and remains
hot for a long time after it has shut down.
OPERATING PRECAUTIONS
Never operate the motor home generator set while
the vehicle is parked over dry leaves, dry grass or
any other combustible substance. The generator’s
exhaust system becomes extremely got and can
cause fire if it is too close to combustible materials.
