Remove and clean the lower dirt/swirl chamber.
Make sure the openings near the base of
chamber and in the air cleaner cover/housing, are
not blocked or restricted. See Figure 13.

with wing nut, then install the precleaner over the
element. If element is not secured with a wing nut,
place the precleaner over the element and install it
as an assembly into the cover/housing. Narrow

base.

Clean Air Intake/Cooling Areas
To ensure proper cooling, make sure the grass screen,
cooling fins, and other external surfaces of the engine
are kept clean at all times.
Every 100 hours of operation (more often under
extremely dusty, dirty conditions), remove the blower
housing and other cooling shrouds. Clean the cooling
fins and external surfaces as necessary. Make sure the
cooling shrouds are reinstalled.
NOTE: Operating the engine with a blocked grass
screen, dirty or plugged cooling fins, and/or
cooling shrouds removed, will cause engine
damage due to overheating.
Ignition System
This engine is equipped with a dependable electronic
magneto ignition system. Other than periodically
checking/replacing the spark plug, no maintenance,
timing, or adjustments are necessary or possible with
this system.
In the event starting problems should occur which are
not corrected by replacing the spark plug, see your
Kohler Engine Service Dealer for trouble analysis.
