7. When replacement is necessary order genuine
Kohler parts.
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.
Check Spark Plug
Every 200 hours of operation, remove the spark plug,
check 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
®
Premium
Gold 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.
Service Paper Element
Every 100 hours of operation replace the paper
element, if equipped with a precleaner. Check every 25
hours of operation if not equipped with a precleaner.
(More often under extremely dusty or dirty conditions.)
1. Loosen the air cleaner cover knob and remove the
cover. Remove the wing nut and remove the air
cleaner element with precleaner (if so equipped).
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
damaged. Also, check the air cleaner cover for
damage or improper fit. Replace all damaged air
cleaner components.
4. If any loose dirt or debris fell on the air cleaner
base when the element was removed, carefully
remove it and wipe the base clean. Be careful that
none of it drops into the intake throat. Check the
condition of the rubber seal on the air cleaner
stud. If condition is questionable in any way,
replace it with the new seal packaged with the
replacement element.
5. Install the precleaner over the element. Install the
element with precleaner on the base and secure it
with the wing nut. Reinstall the cover and tighten
the knob securely.
6. When replacement is necessary order genuine
Kohler parts.
