Carburetor Adjustment - Craftsman 580.675610 Operator's Manual

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.
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.
Contact with muffler area can result in serious
burns.
Exhaust heat/gases can ignite combustibles,
structures or damage fuel tank causing a fire.
• DO NOT touch hot parts and AVOID hot exhaust gases.
• Allow equipment to cool before touching.
• Keep at least 5 feet (152 cm) of 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.
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".
Check Valve Clearance
Regular valve clearance check and adjustment will improve
performance and extend engine life. This procedure cannot
be done without partial engine disassembly and the use of
special tools. For this reason we recommend that you have a
Sears or other qualified service dealer check and adjust valve
clearance at recommended intervals.

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 a Sears or other
qualified service 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.
