ENGINE
Major repairs should NOT be attempted without a
thorough knowledge of all components of the engine.
Therefore, we strongly recommend having service or
repairs performed by an authorized engine dealer.
General maintenance, filter changes, oil changes,
etc., should be performed as recommended by the
Kohler Engine Operation and Maintenance Manual.
Use the engine manual as a detailed guide for all
matters concerning the engine. The following is a
condensed version of maintenance procedures:
1. Check the engine oil level daily, when in use.
Make certain that proper oil level is maintained.
NEVER overfill. Use high quality detergent oil of
at least API (American Petroleum Institute)
service class SF or SG. Select the viscosity
based on the air temperature at the time of
operation as shown in the following table.
NOTE: Using less than service class SF or
SG oil or extending oil change intervals
longer than recommended can cause engine
damage.

changed after the first five hours of operation.
