Operator’s Manual

The engine is designed and adjusted to operate most efficiently at the follow-
ing conditions:

▪ Air temperature of 25° C ( 77° F)

▪ Atmospheric pressure of 100 kPa (14.5 psi)

▪ Relative humidity of 30 %

Operation of the engine at conditions other than above will affect perfor-
mance and exhaust emissions. Normally the equipment manufacturer takes
this into account during the design of the machine and your equipment will
perform within specifications over a wide range of climatic conditions. How-
ever if you must operate your equipment under very unusual climatic condi-
tions, please contact your nearest Hatz distributor for advice.

MAINTENANCE SCHEDULE-EPA-RELATED PARTS

The following minimum intervals are being adopted for adjustment, cleaning,
repair, or replacement of following components:

At 1.500 hours, and 1.500-hours intervals thereafter:

▪ Fuel injector tips (cleaning only)

At 3.000 hours, and 3.000-hours intervals thereafter:

▪ Fuel injector(s)

The exhaust quality of the engines can be influenced by the execution (the
quality of execution) of above described maintenance work.

Therefore, the maintenance work has to be carried out by a qualified work-
shop.
