Clean Spark Arrester Screen
The engine exhaust muffler may be equipped a spark arrester
screen. If equipped, inspect and clean the screen every
50 hours of operation or once each year, whichever comes
first.
If you use your air compressor 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.
If the engine has been running, the muffler will be very hot.
Allow the muffler to cool before servicing the spark arrester.
1. Remove spark arrester screen for cleaning and inspection.
2. 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.
3. Reattach spark arrester screen to muffler.
NOTE: You can purchase a new spark arrester screen by
contacting your local Briggs & Stratton service center.
Air Cooling System
Over time debris may accumulate in cylinder cooling fins and
cannot be removed without partial engine disassembly. For
this reason, we recommend you have an authorized Briggs &
Stratton service dealer clean the cooling system per
recommended intervals (see Maintenance Schedule in
beginning of Maintenance section). Equally important is to
keep top of engine free from debris. See Cleaning.
WARNING
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 (1.5 m) of clearance on all sides of air
compressor 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.
