ENGINE
1. Check the engine oil level daily. Ensure that
the proper oil level is maintained. NEVER
overfill.
2. Change the oil after the first 5 to 8 hours of
operation. Thereafter, change oil and oil filter
every 50 to 100 hours of operation.
USE ONLY KOHLER OIL FILTERS. USE OF
ANY OTHER TYPE OF OIL FILTER WILL
VOID ENGINE WARRANTY.
Use high-quality oil of at least API (American
Petroleum Institute) service class SJ or higher.
Do not use additives. High quality 30W oil is
recommended. A 10-30 synthetic blend may be
used after 50 hours of operation for a new or
rebuilt engine to allow the piston rings to
properly seat. It is never recommended to extend
oil change intervals past 100 hours.
NOTE: Using a lower service class oil or
extending oil change intervals longer than
recommended can cause engine damage.
NOTE: Synthetic oils meeting the listed
classifications may be used with oil changes
performed at recommended intervals. However to
allow piston rings to properly seat, a new or
rebuilt engine should be operated for at least 50
hours using standard petroleum based oil before
switching to synthetic oil.
3. Check the spark plugs every 200 hours and
clean if necessary. Replace spark plugs every
1000 hours. NEVER sandblast spark plugs.
Spark plugs should be cleaned only by scraping
or wire brushing.
4. Clean the engine air filter element every 200
hours. Replace the element every 1000 hours.
