CONTROL PANEL FEATURES
Low Oil Shut Off System
The low oil shut off is designed to prevent the engine from being
damaged because of a lack of oil in the crankcase. Before the oil
level falls to an unsafe level the engine will shut off.Although the
engine is automatically shut off, the engine switch will still remain
in the ON position.
Turn off the generator immediately and add the proper amount of
oil to the engine.
Refer to the Maintenance Schedule and the Engine Oil section.
V.F.T. Digital Meter Display
The V.F.T. digital meter displays the running voltage, the running
frequency and both the current time of use and the continuous
time of use for maintenance purposes.
Circuit Breaker
The circuit breaker protects the individual circuit protectors and
the 30A120V/240V receptacle. The circuit breaker will
automatically switch OFF if the circuit is overloaded or if the
appliance plugged into the circuit is faulty. If the circuit breaker is
switched OFF automatically, check that the appliance is working
properly and that it does not exceed the rated load capacity of the
circuit before switching the circuit breaker ON again.
Circuit Protector
The circuit protectors will automatically switch OFF if the individual
circuit is overloaded or the appliance plugged into the circuit is
faulty. If the circuit protector is switched OFF automatically, check
that the appliance is working properly and that it does not exceed
the rated load capacity of the circuit before resetting the circuit
protector by pressing the reset buttons.

OPERATING THE GENERATOR
Pre-Operation Checklist
Engine Oil Recommendations
SAE 10W-30 standard motor oil is recommended for normal
operating conditions and temperatures (between 0°F and 100°F). Checking Oil Level
1. Have your generator on a flat, level surface. Stop generator
from running.Allow to completely cool.
2. Remove the oil filter cap and wipe the dipstick clean with a
clean cloth.
3. Check the oil level by inserting the dipstick in the filter neck
without screwing it in, then remove it. If the level is below the
lower level line, add the recommended oil until the level
reaches the upper mark on the dipstick.
4. When filled to the upper level line, the generator holds a
maximum of .32 oz (1 L) of oil.
5. Refer to the Maintenance Schedule for regular service
intervals.

13Customer Support: 1-866-409-4581
GENERATOR
Fuel
This engine is designed to run properly using unleaded gasoline
with an octane number of 87 or higher.
Leaded gasoline or lower octane gasolines are not recommended
and can cause unusual wear on the exhaust system and spark
plugs.
Note: Occasional light spark knocks, “pinging” and metal tapping
noises are normal while operating under heavy loads. If “pinging”
or “knocking” or loud metal tapping occurs during steady engine
speeds under normal load, shut off the engine and replace fuel
with fresh gasoline.
If these noises persist go to an authorized GMC╟Portable
Gasoline Generator Service Center.
Gasoline Containing Alcohol
Oxygenated fuel is blended with alcohol or other additives to
increase octane quality, enhance combustion, and reduce
exhaust emissions. If you use oxygenated fuel, it must have an
octane of 87 or higher as recommended above.
Gasoline containing more than 10% Ethanol (Gasohol) is not
recommended. Gasoline containing 5% or less of Methanol must
contain co-solvents and corrosion inhibitors to protect the fuel
system. Never use gasoline with more than 5% Methanol.
Adding Fuel
1. Have your generator on a flat, level surface.
2. Check fuel tank gauge.Add fuel if the level is low.
3. Remove the fuel cap and filter. Clean filter and replace. Fill
tank. Do not overfill.
4. After refueling, replace the fuel tank cap tightly.
5. Fuel tank capacity is 7.4 gal.

14 Customer Support: 1-866-409-4581
GENERATOR
Generator Exhaust
Generator exhaust contains carbon monoxide (CO). This is a
poison you can not see or smell. If you can smell the generator
exhaust, you are breathing CO. However even if you cannot
smell the exhaust, you could be breathing CO.
nNEVER use a generator inside homes, garages, crawlspaces,
or other partly enclosed areas. Deadly levels of carbon
monoxide can build up in these areas. Using a fan or opening
windows and doors does NOT supply enough fresh air.
nONLY use a generator outside and far away from windows,
doors, and vents.These openings can pull in generator
exhaust. Even when you use a generator correctly, CO may
leak into the home.ALWAYS use a battery-powered or
battery-backup CO alarm in the home.
nIf you start to feel sick, dizzy, or weak after the generator has
been running, move to fresh air RIGHTAWAY. See a doctor.
You could have carbon monoxide poisoning.
Select a safe and suitable location
The generator should only be operated outdoors on a firm, level
surface in a well-ventilated area.At least 5 feet of clearance
should be maintained in relation to any structures or objects, and
this includes space above the generator. The generator could
ignite nearby materials.
nDO NOT operate the generator in wet weather or in wet
conditions.
nDO NOT place or store any items on the generator.
nKeep children and pets away from the generator.
nCheck the wheels before use.
nHearing protection is recommended.

Before Operation
nCheck with your local authority and local utility company
before using your generator. There may be local regulations
regarding generators.
nAdditional requirements may apply to construction sites.
nConsult a qualified electrician if you have questions regarding
the proper use of the generator, including any electrical
devices to be connected.
When this generator is used to supply a building wiring
system:
nTransfer switch MUST be used when connecting generator to
a building’s electrical system.
nGenerator must be installed by a qualified electrician and
connected to a transfer switch as a separately derived system
in accordance with the National Electrical Code, NFPA70.
nThe generator should be connected through a transfer switch
that switches all conductors other than the equipment
grounding conductor.
Grounding
nAlways ground the generator.
The faceplate of your generator is marked with the
following grounding symbol, which is located above the
grounding terminal:
nAttach a heavy gauge copper wire (12AWG minimum) to this
terminal and link it to a copper rod driven into the ground.
Consult an electrician to ensure compliance with local codes
and regulations.

Starting the Generator
1. Make sure theAC circuit breaker is in the OFF position.
2. Turn the fuel valve lever to the ON position. 3. Pull choke lever out to the CLOSED position.
4. Turn the engine switch to the ON position.

17Customer Support: 1-866-409-4581

5. For Recoil Starter – Pull the starter grip lightly until resistance
is felt, then pull rapidly.
6 .Push the choke lever to the OPEN position as engine warms
up.The choke is used to provide the proper mixture when the
engine is cold. It can be opened and closed by operating the
choke lever manually. Move the lever to the closed position to
enrich the mixture for cold starting.

Using Electric Power
AC Application
1. Check voltmeter for proper voltage.
.
4. Turn theAC circuit breaker to the ON position.
5. Turn on the ON switch(es) to the appliance(s) that are
connected to the generator.
Notes:
nDo not exceed the generator’s capacity.
nCalculate the total wattage of all the devices you will connect
to the generator. Make sure that the total wattage is below the
capacity of the generator.
nIf the generator's capacity is exceeded or “overloaded” the
circuit breakers will stop the flow of electricity from the
generator to the appliances. If this happens, power OFF the
generator and disconnect the appliances. Wait a few minutes
and then push the RESET circuit breaker switch.
nMany electrical devices require more starting watts than
running watts, a phenomenon known as “surge watts” or
“starting watts.” Make sure to account for this when calculating
the amount of watts that will be applied.
nIf an appliance begins to operate abnormally or becomes
sluggish or stops suddenly, turn off the appliance immediately
and disconnect the appliance from the generator.
2. Turn OFF the switch(es) on the electrical appliance(s)
before connecting to the generator
3. Insert the plug(s) of the electrical appliance(s) into the
receptacle(s).
