Fuel
Gasoline
Fuel requirements are as follows:
• Clean, fresh, unleaded gasoline.
• Minimum rating of 87 octane/87 AKI (91
RON).
• Up to 10% ethanol (gasohol) is acceptable
(where available; non-ethanol-premium fuel
is recommended).
• DO NOT use E85.
• DO NOT use a gas oil mix.
• DO NOT modify engine to run on alternate
fuels. Stabilize fuel prior to storage.
1. Verify unit is OFF and cooled for a mini-
mum of two minutes prior to fueling.
2. Place unit on level ground in a well venti-
lated area.
3. Clean area around fuel cap and remove
cap slowly.
4. Slowly add recommended fuel (A). Do not
overfill (B). See Figure 2-12.

Figure 2-12. Add Recommended Fuel
NOTE: Allow spilled fuel to evaporate before
starting unit.
IMPORTANT NOTE: It is important to pre-
vent gum deposits from forming in fuel
system parts such as the carburetor, fuel
hose or tank during storage. Alcohol-
blended fuels (called gasohol, ethanol or
methanol) can attract moisture, which
leads to separation and formation of acids
during storage. Acidic gas can damage the
fuel system of an engine while in storage.
To avoid engine problems, the fuel system
should be emptied before storage of 30
days or longer. See the Storage section.
Never use engine or carburetor cleaner
products in the fuel tank as permanent
damage may occur.
Liquid Petroleum Gas (LPG)
NOTE: LPG regulator inlet pressure is approx-
imately 30 psi at 0 °F, and 218 psi at 100 °F.
• Use only standard 20 or 30 pound capacity
LPG tanks with Type 1, right hand Acme
threads with this generator. Verify re-qualifi-
cation date on tank has not expired. Do not
use rusted or damaged cylinders.
• All new cylinders must be purged of air and
moisture prior to filling. Used cylinders that
have not been plugged or kept closed must
also be purged.
• The purging process should be done by the
propane gas supplier. (Cylinders from an
exchange supplier should have been
purged and properly filled by supplier).
Connect LPG Tank
1. Remove safety plugs or caps from cylinder
valve, generator mounted regulator, and
regulator connecting hose ends.
2. With LPG tank closed, attach LPG regula-
tor connecting hose into valve. Turn plastic
coupling from the hose right (clockwise) to
tighten hose assembly onto LPG tank.
See Figure 2-13.
Figure 2-13. Connect Hose Assembly to LPG
Tank
3. Connect opposite regulator connecting
hose end to generator at mounted LPG
primary regulator with a 3/4 in. (19mm)
wrench (not supplied). See Figure 2-14.

Grounding the Generator When
In Use
The generator is equipped with a terminal for
the connection of a grounding electrode sys-
tem. NEC Article 250.34 (A) does not require
the frame of the generator to be connected to
a grounding electrode system when the gen-
erator only supplies power to cord and plug
connected equipment through the receptacles
on the generator.
When the generator supplies power to a 3-
pole manual transfer switch or distribution
panel boards for temporary power, a ground-
ing electrode system shall be installed and
connected to the grounding electrode terminal
on the generator. See NEC 250.30, 250.34
and 250.52 for clarification. See Figure 3-1.
• Neutral Bonded to Frame.

Special Requirements
Review all Federal and State Occupational
Safety and Health Administration (OSHA) reg-
ulations, local codes, and ordinances applica-
ble to the intended use of the generator.
Additional regulations may apply if the genera-
tor is used at a construction site.
Consult a qualified electrician, electrical
inspector, or the local agency having jurisdic-
tion for additional requirements that may be
unique to your area, such as whether the gen-
erator is required to be registered with local
utility.
Connecting the Generator to a
Building Electrical System
It is recommended to use a manual transfer
switch when connecting directly to a building
electrical system. Connecting a portable gen-
erator to a building electrical system must be
made in strict compliance with all national and
local electrical codes and laws, and be com-
pleted by a qualified electrician.

Know Generator Limits
Overloading a generator can result in damage
to the generator and connected electrical
devices. Observe the following to prevent
overload:
• Add up the total wattage of all electrical
devices to be connected at one time. This
total should NOT be greater than the gener-
ator's wattage capacity.
• The rated wattage of lights can be taken
from light bulbs. The rated wattage of tools,
appliances, and motors can be found on a
data label or decal affixed to the device.
• If the appliance, tool, or motor does not
give wattage, multiply volts times ampere
rating to determine watts (volts x amps =
watts).
• Some electric motors, such as induction
types, require about three times more watts
of power for starting than for running. This
surge of power lasts only a few seconds
when starting such motors. Make sure to
allow for high starting wattage when select-
ing electrical devices to connect to the gen-
erator:
1. Figure the watts needed to start the largest
motor.
2. Add to that figure the running watts of all
other connected loads.
The Wattage Reference Guide is provided to
assist in determining how many items the gen-
erator can operate at one time.
NOTE: All figures are approximate. See data
label on appliance for wattage requirements.
