Service Air Cleaner
Your engine will not run properly and may be damaged if
you run it using a dirty air cleaner.
Check the air cleaner every use and clean or replace the
air cleaner every 25 hours of operation or yearly,
whichever comes first. Clean or replace more often if
operating under dusty or dirty conditions.
To clean or replace air cleaner:
1. Loosen air cleaner cover screws and remove cover.
2. Remove the foam air cleaner and retainer.
3. Wipe clean inside of air cleaner housing and cover
thoroughly.
4. Wash air cleaner in a solution of household detergent
and warm water, then rinse thoroughly. Squeeze dry in
a clean cloth.
5. Saturate air cleaner in clean engine oil and squeeze in a
clean, absorbent cloth to remove all excess oil. DO
NOT twist.
IMPORTANT: The engine will smoke during initial start-
up if too much oil is left in the air cleaner.
NOTE: If you need to order a new air cleaner, please call
1-800-743-4115.
6. Reinstall the retainer, air cleaner and cover. Tighten
the air cleaner cover screws.
Clean Spark Arrester Screen
The engine muffler is equipped with a removable spark
arrester screen. Inspect and clean the screen every
10 hours of operation or every 3 months, whichever comes
first, as shown in Figure 16:

1. Loosen screw on muffler tail pipe and remove spark
arrester screen.
2. Use a brass or stiff-bristle brush to remove carbon
deposits from spark arrester surface.
3. Inspect spark arrester for breaks or tears and replace
if necessary.
NOTE: If you need to order a new spark arrester, please
call 1-800-743-4115.
4. Install clean screen in reverse order of removal.
NOTE: If you use your generator on any forest-covered,
brush-covered or grass-covered unimproved land, it must
have a spark arrester installed. The spark arrester must be
maintained in good condition by the owner/operator.
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 an authorized
Briggs and Stratton Power Products service dealer clean
the cooling system (Figure 17) per recommended intervals
(see "Maintenance Schedule" on page 15). Equally
important is to keep top of engine free from debris. See
"Generator Cleaning".
