DON'T OVERLOAD

GENERATOR

Capacity

You must make sure your generator can supply enough
rated (running) and surge (starting) watts for the items you
will power at the same time. Follow these simple steps:

1. Select the items you will power at the same time.

2. Total the rated (running) watts of these items.This is
the amount of power your generator must produce to
keep your items running. See Figure 11.

3. Estimate how many surge (starting) watts you will
need. Surge wattage is the short burst of power
needed to start electric motor-driven tools or
appliances such as a circular saw or refrigerator.
Because not all motors start at the same time, total
surge watts can be estimated by adding only the
item(s) with the highest additional surge watts to the
total rated watts from step 2.

Example:

Total Rated (Running) Watts = 3075
Highest Additional Surge Watts = 1800
Total Generator Output Required = 4875

Power Management

To prolong the life of your generator and attached devices,
it is important to take care when adding electrical loads to
your generator.There should be nothing connected to the
generator outlets before starting it's engine.The correct
and safe way to manage generator power is to sequentially
add loads as follows:

1. With nothing connected to the generator, start the
engine as described in this manual.

2. Plug in and turn on the first load, preferably the largest
load you have.

3. Permit the generator output to stabilize (engine runs
smoothly and attached device operates properly.

4. Plug in and turn on the next load.

5. Again, permit the generator to stabilize.

6. Repeat steps 4 and 5 for each additional load.
NEVER add more loads than the generator capacity.Take

special care to consider surge loads in generator capacity,
as described above.

*Wattages listed are approximate only. Check tool or
appliance for actual wattage.

Generator Maintenance

Generator maintenance consists of keeping the unit clean
and dry. Operate and store the unit in a clean dry
environment where it will not be exposed to excessive
dust, dirt, moisture or any corrosive vapors. Cooling air
slots in the generator must not become clogged with
snow, leaves or any other foreign material.

NOTE: DO NOT use a garden hose to clean generator.
Water can enter engine fuel system and cause problems. In
addition, if water enters generator through cooling air slots,
some of the water will be retained in voids and cracks of
the rotor and stator winding insulation.Water and dirt
buildup on the generator internal windings will eventually
decrease the insulation resistance of these windings.

To Clean the Generator

• Use a damp cloth to wipe exterior surfaces clean.

• Use a soft bristle brush to loosen caked on dirt or oil.

• Use a vacuum cleaner to pick up loose dirt and debris.

• Use low pressure air (not to exceed 25 psi) to blow
away dirt. Inspect cooling air slots and opening on
generator.These openings must be kept clean and
unobstructed.

• Used motor oil has been shown to cause skin cancer in
certain laboratory animals.

• Thoroughly wash exposed areas with soap and water.

Avoid prolonged or repeated skin contact with used
motor oil.

CAUTION

• DO NOT expose generator to excessive moisture, dust,dirt,
or corrosive vapors.

• DO NOT insert any objects through cooling slots.

Improper treatment of generator can damage it and
shorten its life.

CAUTION

WHEN ADJUSTING OR MAKING REPAIRS TO YOUR
GENERATOR

• Disconnect the spark plug wire from the spark plug and place
the wire where it cannot contact spark plug.

WHEN TESTING FOR ENGINE SPARK

• Use approved spark plug tester.

• DO NOT check for spark with spark plug removed.

Unintentional sparking can result in fire or
electric shock.

STORAGE

The generator should be started at least once every seven
days and allowed to run at least 30 minutes. If this cannot
be done and you must store the unit for more than
30 days, use the following guidelines to prepare it for
storage.

Generator Storage

• Clean the generator as outlined in “To Clean the
Generator.”

• Check that cooling air slots and openings on generator
are open and unobstructed.

Engine Storage

See engine owner’s manual for instructions.

Other Storage Tips

• Always store unit with fuel shut off valve in the “Off”

position (Figure 4, earlier).

• To prevent gum from forming in fuel system or on
essential carburetor parts, empty entire contents of both
supplied fuel stabilizer containers into fuel tank and fill
with fresh fuel. Run the unit for several minutes to
circulate the additive through the carburetor.The unit
and fuel can then be stored for up to 24 months.
Additional fuel stabilizer can be purchased locally.

• Fuel tank may swell in storage if vent is closed.When
storing generator with fuel in the tank, make sure the
vent knob is turned fully counter-clockwise.

• Store unit in clean and dry area.

• DO NOT place a storage cover over a hot generator.

• Let equipment cool for a sufficient time before placing the
cover on the equipment.

Storage covers can be flammable.
