4. Saturate the precleaner with new engine oil.
Squeeze out all excess oil.
5. Reinstall the precleaner over the paper element.
6. Reinstall the air cleaner cover and tighten the
knob securely.
7. When precleaner replacement is necessary order
Part No. 52 083 01-S.
Service Paper Element
Every 100 hours of operation (more often under
extremely dusty or dirty conditions), replace the paper
element.
1. Loosen the air cleaner cover knob and remove the
cover. Remove the wing nut and then remove the
air cleaner element with precleaner. Remove the
precleaner from the element and service as
necessary.
2. Do not wash the paper element or use
pressurized air, as this will damage the element.
Replace a dirty, bent, or damaged element with a
genuine Kohler element. Handle new elements
carefully; do not use if the sealing surfaces are
bent or damaged.
3. When servicing the air cleaner, check the air
cleaner base. Make sure it is secured and not
bent or damaged. Also check the element cover
for damage or improper fit. Replace all damaged
air cleaner components.
4. Reinstall all components as described above.
5. When air cleaner element replacement is
necessary order Part No. 47 083 01-S.
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 plugs, see your
Kohler Engine Service Dealer for trouble analysis.
Check Spark Plug
Every 200 hours of operation, remove the spark plug,
check its condition, and reset the gap or replace with a
new plug as necessary. The standard spark plug is a
Champion
®
RC12YC (Kohler Part No. 12 132 02-S). A
high-performance spark plug, Champion
2071 (used on Pro Series engines, Kohler Part No.
12 132 06-S), is also available. Equivalent alternate
brand plugs can also be used.
1. Before removing the spark plug, clean the area
around the base of the plug to keep dirt and debris
out of the engine.
2. Remove the plug and check its condition. Replace
the plug if worn or reuse is questionable.
NOTE: Do not clean the spark plug in a machine
using abrasive grit. Some grit could remain
in the spark plug and enter the engine
causing extensive wear and damage.
3. Check the gap using a wire feeler gauge. Adjust
the gap by carefully bending the ground electrode.
