Paper Element

3. After the paper element is removed, check the
condition of the inner element. It should be
replaced whenever it appears dirty, typically
every other time the main element is replaced or
every 600 hours. Clean the area around the base
of the inner element before removing it, so dirt
does not get into the engine.
4. Do not wash the paper element and inner
element or use compressed air, this will damage
the elements. Replace dirty, bent or damaged
elements with new genuine Kohler elements as
required. Handle the new elements carefully;
do not use if the sealing surfaces are bent or
damaged.
5. Check all parts for wear, cracks, or damage, and
make sure ejector area is clean. See Figure 11.
Replace any damaged components.

Clean Air Intake/Cooling Areas
To ensure proper cooling, make sure the fixed guard,
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. Reinstall the
blower housing and other cooling shrouds.
NOTE: Operating the engine with a blocked fixed
guard, dirty or plugged cooling fins, and/or
cooling shrouds removed, will cause engine
damage due to overheating.
Ignition System
EFI Engines incorporate a computer-controlled battery
ignition system with individual coils. Other than
periodically checking/replacing the spark plugs, no
maintenance, timing, or adjustments are necessary or
possible with this system.
Check Spark Plugs
Every 200 hours of operation, remove the spark plugs,
check condition, and reset the gap or replace with
new plugs as necessary. The standard spark plug is a
