5. Visually inspect the spark plug. Discard it if the insulator is cracked or chipped.
Clean the spark plug with a wire brush if it is to be reused.
6. Measure the plug gap with a feeler gauge.
The gap should be 0.6~0.7mm (0.024-0.028in). Correct as necessary by carefully bend-
ing the side electrode.
7. Install the spark plug carefully, by hand, to avoid cross-threading.
8. After a new spark plug has been seated by hand, it should be tightened 1/2 turn with
a wrench to compress its washer.
If a used plug is being reinstalled, it should only require 1/8 to 1/4 turn after being
seated.
9. Reinstall the spark plug cap on the spark plug securely.
10. Reinstall the spark plug maintenance cover.
CAUTION
The spark plug must be securely tightened. An improperly tightened plug can
become very hot and possibly damage the generator.
Never use a spark plug with an improper heat range.
Never use a spark plug without damping resistance, or it will cause no AC
output.

Gasolines containing alcohol
If you decide to use a gasoline containing alcohol (gasohol), be sure it's octane rating is
at least as high as that recommended by us. There are two types of gasohol : one
containing ethanol, and the other containing methanol. Do not use gasohol that contains
more than 10% ethanol. Do not use gasoline containing methanol (methyl or wood
alcohol) that does not also contain cosolvents and corrosion inhibitors for methanol.
Never use gasoline containing more than 5% methanol, even if it has cosolvents and
corrosion inhibitors.
Fuel tank capacity: 3.7 liter (0.97 US gal, 0.81 lmp gal)
UPPER LIMIT MARK
NOTE
Fuel system damage or engine performance problems resulting from the use of
fuels that contain alcohol is not covered under the warranty. We cannot en-
dorse the use of fuels containing methanol since evidence of their suitability is
as yet incomplete.
Before buying fuel from an unfamiliar station, try to find out if the fuel contains
alcohol, if it does, confirm the type and percentage of alcohol used. If you
notice any undersirable operating symptoms while using a gasoline that
contains alcohol, or one that you think contains alcohol, replace it by a gasoline
that you know does not contain alcohol.
