Clean Spark Arrestor Screen
The engine exhaust muffler has a spark arrestor
screen. Inspect and clean the screen every 50
hours of operation or once each year, whichever
comes first.
NOTE: If you use your generator on any forest-
covered, brush-covered or grass-covered unimproved
land, it must have a spark arrestor. The spark arrestor
must be maintained in good condition by the owner/
operator. The proceeding is required by the law in the
state of California. Other states may have similar laws.
Federal laws apply on federal lands.
WARNING
: Let the muffler cool before working
on it. Contact with a hot muffler or engine can
cause severe burns.
To clean and inspect the spark arrestor:
• Remove four screws that attach the spark arrestor
screen.
• Inspect screen and replace if torn, perforated or
otherwise damaged. DO NOT USE a defective
screen. If screen is not damaged, clean it with
commercial solvent.
• Reattach the screen with four screws.
Engine Governed Speed
CAUTION
! The engine speed was properly
adjusted at the factory and should require no
additional adjustment. Do not attempt to change
engine speed. If you believe the engine is
running too fast or too slow, take your engine to
an authorized service center for repair and
adjustment. CHANGING THE ENGINE
GOVERNED SPEED WILL VOID THE ENGINE
WARRANTY.
Your engine runs at a constant speed. This constant
operating speed is maintained by a mechanical fixed
speed governor. DO NOT try to adjust the governed
speed setting for the following reasons:
• Operating the engine at high engine speeds is
dangerous and increases the risk of personal injury
or damage to the equipment.
• Operating the engine at low engine speeds with
heavy loads may shorten the engine's life.
Incorrect speed settings also affects electrical
operation of your generator as follows:
• Operating at high speeds results in an over-
frequency and over-voltage condition.
• Operating at low speeds causes an under-
frequency and under-voltage condition.
IMPORTANT
: Incorrect frequency and/or voltage may
damage some connected electrical loads.
If you suspect engine speed is incorrect, take the
generator to an authorized service facility for
repair and adjustment.
