ENGINE _________________________________________________________________

IMPORTANT - The mower includes a separate Engine Manual prepared by the engine manufacturer. Read the Engine
Manual and know the operation and maintenance of the engine. When you follow the engine manufacturer instructions,
you will make sure of the maximum service life of the engine. The replacement engine manuals are available from the
engine manufacturer.
The operation and maintenance during the first 8 hours of a new engine can make a difference to the performance and
life of the engine.
During the first 8 hours of operation, Jacobsen recommends the following.
• Allow the engine to reach a temperature of at least 140° F (60° C) before operation at full load.
• Check the engine oil level two times each day. Higher than normal oil use can occur during the first 8 hours.
• Change the engine oil and oil filter after the first 8 hours of operation.
• Refer to the Engine manual for specified maintenance intervals.
The mower operates and cuts correctly at the preset governor setting. Do not change the engine governor setting
or over speed the engine.
