Extension Cord Selection
Refer to the above table to ensure the extension cord
used has the capacity to carry the required load.
If the size of the cable is inadequate it can cause
a voltage drop, which can damage the electrical
device and cord.
Moving the Generator
• Disconnect any electronic devices from generator
then turn generator off.
• Turn fuel valve to the “OFF” position.
• Tilt generator until it balances on wheels. Roll
machine to desired location.
• If the generator must be carried, fold handle to
the down position. Never lift or carry generator
by its handle.
This product is heavy and requires at least two
people to lift. Lift and lower with your legs,
not your back, to avoid injury. This is done by
bending at the knees, not your back.
Don’t Overload the Generator
Make sure you can supply enough rated watts and
surge watts for all electrical devices connected to the
generator. Rated watts refer to the power a generator
must supply to keep a device running. Surge watts
refer to the power a generator must supply to start
an electrical device. This power surge for starting a
device usually lasts between 2-3 seconds but this
additional output must be taken into account when
selecting the electrical devices you plan to attach to
the generator. To prevent overloading the generator
take the following steps:
1. Add up the total rated wattage of all electronic
devices that will be connected to the generator
simultaneously.
2. Estimate surge watts by adding the item(s) with
the highest output (it is unnecessary to calculate
the surge output for all devices as they should
be connected one at a time).
3. Add the Surge Watts to the total Rated Watts
in step 1. Keep the total load within generator’s
power capacity.

Operation Cont.
Operating Voltage and Frequency
Operating voltage and frequency requirement of
all electronic equipment should be checked prior
to plugging them into this generator. Damage may
result if the equipment is not designed to operate
within a +/- 10% voltage variation, and +/- 3 Hz
frequency variation from the generator name plate
ratings. To reduce the risk of damage, always have
an additional load plugged into the generator if solid
state equipment (such as television set) is used. A
power line conditioner is recommended for some
solid state applications.

Never exceed generator’s wattage/
amperage capacity. This could damage
the generator and connected electrical devices.
• Verify the operating voltage and frequency
requirements of all electrical devices prior to
plugging in to the generator.
Hour Meter (Figure 17)
Use this meter along with the manual to determine
when and what type of service on the unit is needed.
The display will show the word “Lube” at the first 25
hours of operation and again at every 100 hours of
operation after.
Power Management
• Start the generator without anything connected.
• When the engine has stabilized, plug in and turn on
the first load. It is strongly recommended to plug
in devices starting with the largest load first and
the smallest load last to help prevent overloading
the generator.
• Allow the generator output to stabilize (engine
and attached devices run evenly) before plugging
in the next load.
Charging a 12 Volt Battery (Figure 18)
This generator can be used to charge a 12 volt
automotive/storage batteries with the following steps:
• Inspect fluid level of the battery cells.
• Add ONLY distilled water to any cell where fluid
level is low. Never add tap water.
• Use a wire brush to clean the battery terminals
if they are corroded.
• Connect the Battery Charging Cable to the 12
Volt DC posts.
• Connect the red cable clamp to the positive (+)
battery terminal.
• Connect the black cable clamp to the negative
(-) battery terminal.
• Start generator engine. Let the engine run while
the battery charges.
• Battery is considered fully charged when the
static voltage is >12.7 vdc.
Cold Weather Operation
Under humid conditions where temperatures drop to
40ºF (4ºC) the carburetor and/or crankcase breather
system may begin to freeze. To prevent cold weather
performance issues, take the following steps:
1. Replace any old fuel with clean, fresh fuel.
2. Use SAE30 or SAE 10W-30 engine oil. Check oil
daily or after every 8 hours of use.
3. Ensure generator is serviced according to the
maintenance schedule under “Maintenance”
section of the manual.
4. Shelter unit from elements.

Maintenance Schedule
Pre-Operation Steps
Before starting the engine, perform the following
pre-operation steps:
• Check the level of the engine oil and the fuel tank
level. Check for any leakage.
• Make sure the air filter is clean.
• Remove any debris that has collected on the
generator and around the muffler and controls.
Use a vacuum cleaner to pick up loose debris. If
dirt is caked on, use a soft bristle brush.
• Inspect work area for hazards.
After Each Use
Perform the following procedure after each use:
• Turn the FUEL VALVE Knob to “OFF”
• Switch OFF the engine
• Switch Off the battery
• Wait for the generator to become cool to
the touch
• Store unit in a clean and dry area.
Before inspecting or servicing this
machine, make sure the engine is off and
no parts are moving. Disconnect the spark plug
wire and move it away from the spark plug.

High Altitude Operation
At high altitude, the standard carburetor air/fuel mixture
will be too rich. Performance will decrease, and fuel
consumption will increase. A very rich mixture will also
foul the spark plug and cause hard starting. Operation
at an altitude that differs from that at which this
engine was certified, for extended periods of time,
may increase emissions. High altitude performance
can be improved by modifying the carburetor.

Maintenance Cont.
Note:
• Below 40º F (4º C) the use of SAE 30 will result
in hard starting.
• Above 80º F (27º C) the use of 10W-30 may
cause increased oil consumption. Check oil level
more frequently
Checking the Spark Plug
• Disconnect the plug wire from the spark plug.
• Before removing the spark plug, clean the area
around its base to prevent debris from entering
the engine.
• Clean carbon deposits off the electrode with a
wire brush.
• Check the electrode gap and gently adjust gap
to 0.70mm-0.80mm (.030-.031”) if necessary.
• Reinstall spark plug and tighten to Torque
22–27 Nm (16-20 ft-lb).
• Reconnect spark plug wire.
• If the spark plug is worn replace only with an
equivalent replacement part. Spark plug should
be replaced annually. (BOSCH F7TC, NGK
BP6ES, CHAMPION N9YC or equivalent)
Changing Oil
• Run the generator until the engine is warm, then
shut OFF.
• Place generator on a firm and level surface,
raised on blocks for easier access.
• Remove the crankcase dipstick.
• Place an oil pan underneath the oil drain hole to
collect used oil.
• Remove the oil drain plug and allow oil to drain
completely.
• Reinstall oil drain plug, tighten securely.
• Carefully add SAE 30 or 10W-30 engine oil to
empty reservoir until the oil reaches the threads
of the oil fill hole (Crankcase Dipstick hole).
• Replace crankcase dipstick.
