IMPORTANT: A separate Engine Manual, prepared by
the engine manufacturer, is supplied with this tractor.
Read the engine manual carefully until you are familiar
with the operation and maintenance of the engine.
Proper attention to
directions will assure maximum service life of the
engine. To order replacement engine manuals contact
the engine manufacturer.
The proper break-in of a new engine can make a
considerable difference to the performance and life of the
engine.

efficiently at the preset governor setting. Do not change the
engine governor settings or overspeed the engine.

at least 140°F (60°C) prior to operation at full load.

2. Check the engine oil level twice daily during the first 50
hours of operation. Higher than normal oil consumption
is not uncommon during the initial break-in period.
3. Change engine oil and oil filter element after first 25
hours of operation.
4. Check and adjust fan and alternator belts.
5. Refer to Section 6.3 and Engine Manual for specific
maintenance intervals.
If the injection pump, injectors or the fuel system require
service, contact an authorized Textron Turf Care And
Specialty Products Dealer.
Important: The normal engine operating temperature is less
than 220° F (104° C). If the engine temperature rises by
more than 10° F (6° C) above normal, there is and indication
that the cooling system may not be functioning properly.
The warning horn will sound when the temperature reaches
230° F (110° C). To prevent damage to the engine, never
allow the engine to operate above 230° F. Stop the machine,
disengage all drives and operate the engine at low idle for 5
minutes.
