7.2
ENGINE _________________________________________________________________
IMPORTANT:
A separate Engine Manual, prepared by
the engine manufacturer, is supplied with this
mower
.
Read the Engine Manual carefully until you
are familiar with the operation and maintenance of
the engine. Proper attention to the engine
manufacturer’s 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.
During the break-in period, Jacobsen recommends the
following:
1.
During the first 50 hours of operation, a new engine
should be allowed to reach an operating temperature
of 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 50
hours of operation.
4.
Check and adjust fan and alternator belts.
5.
Refer to
Section 6.2
and Engine Manual for specific
maintenance intervals.
If the injection pump, injectors or the fuel system require
service, contact an authorized Jacobsen Dealer.
7.3
ENGINE OIL ______________________________________________________________
Check the engine oil at the start of each day, before
starting the engine. If the oil level is low, remove oil filler
cap, and add oil as required.
Perform initial oil change after first 50 hours of operation
and every 400 hours thereafter. See Engine Manual.
Use only engine oils with API classification CJ-4.
