Clean/Replace Spark Plug
Change the spark plug every 100 hours of operation
or once each year, whichever comes first. This will
help your engine to start easier and run better.
1. Clean area around spark plug.
2. Remove and inspect spark plug.
3. Check electrode gap with wire feeler gauge and
set spark plug gap to 0.030 inch (0.76mm) if
necessary.
4. Replace spark plug if electrodes are pitted, burned
or porcelain is cracked. Use a recommended
replacement plug.
5. Install spark plug and tighten firmly.
NOTE: You can purchase a new spark plug by calling
1-800-4-MY-HOME (469-4663).
Clean Spark Arrester Screen
The engine exhaust muffler has a spark arrester
screen. Inspect and clean the screen every 100 hours
of operation or once each year, whichever comes first.
WARNING
Running engines produce heat.
Temperature of muffler and nearby areas
can reach or exceed 150°F (65°C).
Severe burns can occur on contact.
Exhaust heat/gases can ignite combustibles,
structures or damage fuel tank causing a fire.
• DO NOT touch hot surfaces and avoid hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 5 ft. (152 cm) clearance on all sides of
generator including overhead.
• Code of Federal Regulation (CFR) Title 36 Parks,
Forests, and Public Property require equipment powered
by an internal combustion engine to have a spark
arrester, maintained in effective working order, complying
to USDA Forest service standard 5100-1C or later
revision. In the State of California a spark arrester is
required under section 4442 of the California Public
resources code. Other states may have similar laws.
NOTE: You can purchase a new spark arrester screen
by calling 1-800-4-MY-HOME (469-4663).
If you use your generator on any forest-covered, brush-
covered, or grass-covered unimproved land, it must
have a spark arrester. The spark arrester must be
maintained in good condition by the owner/operator.
Clean and inspect the spark arrester as follows:
1. To remove muffler heat shield from muffler, remove
four screws that connect guard to muffler bracket.
Muffler
2. Remove four screws that attach spark arrester
screen.
3. 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.
4. Reattach screen and muffler guard.
Air Cooling System
Over time debris may accumulate in cylinder cooling
fins and cannot be observed without partial engine
disassembly. For this reason, we recommend you
have a Sears or other qualified service dealer clean
the cooling system per recommended intervals (see
"Maintenance Schedule" on page 15). Equally
important is to keep top of engine free from debris.
See "Generator Cleaning".
Carburetor Adjustment
The carburetor on this engine is low emission. It is
equipped with a non-adjustable idle mixture valve and
governed idle, if equipped. Governed idle and top
speed have been set at the factory. If adjustment is
required, see any Sears or other qualified dealer.
Excessively high operating speeds increase risk of
injury and damage to generator.
Excessively low speeds impose a heavy load.
• DO NOT tamper with governed speed. Generator
supplies correct rated frequency and voltage when
running at governed speed.
• DO NOT modify generator in any way.
