When you discard hazardous materials (batteries, lubricants, fuel, anti-freeze), follow your local, state or federal-
recommended procedures.
8.3 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 50 hours of a new engine can make a difference to the
performance and life of the engine.
During the first 50 hours of operation, Jacobsen recommends the following.
• Allow the engine to reach a temperature of at least 60° C (140° F) before operation at full load.
• Check the engine oil level two times each day. Higher than normal oil use can occur during the first 50
hours.
• Change the engine oil and oil filter after the first 50 hours of operation.
• Check the fan belt.
• Refer to the Engine manual for specified maintenance intervals.
If the injection pump, injectors or the fuel system need service, contact your Jacobsen Dealer.
