Never use a spark plug without damping resistance, or
it will cause no AC output.
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 0.6-0.7 mm (0.024-0.028in). Correct as necessary by carefully
bending 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 improp-
erly tightened plug can become very hot and possibly
damage the generator.
Never use a spark plug with an improper heat range.
OFF:
Note:Smart throttle system does not operate. Engine speed is kept over rated speed.
4.SPARK ARRESTER MAINTENANCE(Equipped type only)
If the generator has been running, the muffler will be
very hot. Allow it to cool before proceeding.
The spark arrester must be serviced every 100 hours
to maintain its efficiency.
WARNING
CAUTION
Smart throttle
Engine speed is kept at idle automatically when the electrical appliance is disconnected
and it returns to the proper speed to power of the electrical load when electrical
appliance is connected. This position is recommended to minimize the fuel consumption
while in operation.
WARNING
Smart throttle system does not operate effectively, if the electrical appliance
requires big momentary electric power.
When high electrical loads are connected simultaneously, turn the Smart-
throttle switch to the OFF position to reduce voltage vibration.
In DC operation, turn the Smart-throttle switch to the OFF position.
