Service Paper Element
Every 150 hours of operation (more often under
extremely dusty or dirty conditions) replace the paper
element.
1. Loosen the cover retaining knobs and remove the
cover.
2. Rotate the element latch to release the element.
3. Remove the paper element with precleaner.
4. Remove the precleaner (if so equipped) from the
paper element. Service the precleaner as
described above.
5. 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.
6. When servicing the air cleaner, check the air
cleaner base. Make sure it is secured and not bent
or damaged. Replace all damaged air cleaner
components.
NOTE: 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.
7. Reinstall the paper element with precleaner.
Rotate the element latch to secure the element.
8. Reinstall the air cleaner cover. Secure cover with
the cover retaining knobs.
9. When element 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.
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
An electronic Capacitive Discharge (CD) ignition
system is used. 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. Replace with new
plugs every 600 hours, or as necessary. The standard
spark plug is a Champion
62 132 04-S). 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 to 0.76 mm (0.030 in.) by carefully
bending the ground electrode. See Figure 24.
