• Always wipe up any spilled fuel.
• Be sure not to ll above the upper limit mark
• Always allow room for fuel expansion.
• DO NOT use engine and or carburetor cleaning
products in the fuel tank as this could result in
permanent damage.
• It is important to prevent gum deposits from
forming in essential fuel system components,
such as the carburetor, fuel lter, fuel hose or
tank during longterm storage. Also, experience
indicates that alcohol-blended fuels (gasohol,
ethanol or methanol) can attract moisture,
which could lead to separation and formation
of acids during longterm storage.
• Acidic fuels can damage the fuel system while
in storage. Be sure to review the instructions in
the “Storage” section.
• Petrol/Alcohol Blends: up to 10% alcohol, 90%
unleaded petrol by volume is approved as a

5. GROUNDING
• The generator must be properly connected
to an appropriate ground. It helps prevent
electrical shock if a ground fault condition
exists in the generator or in connected
electrical devices, especially when the unit is
equipped with a wheel kit. Proper grounding
also helps dissipate static electricity, which
often builds up in ungrounded devices.
DANGER
ELECTRICAL SHOCK
Failure to properly ground the generator could result
in electric shocks.
A ground terminal on the frame of the generator has
been provided and can be found on the end of the
generator. For remote grounding, connect a (4 mm2)
length of heavy gauge copper wire between the
generator ground terminal and the copper rod driven
into the ground.
The National Electrical Code requires that the frame
and external electrically conductive parts of this
generator be properly connected to an approved
earth ground. Local electrical codes may also require
proper grounding of the unit. We strongly
recommend that you consult with a qualied
