UNUSUAL OPERATING CONDITIONS.
The engine must not be operated at a load factor less than 25 % for an extended period as such operation will cause
the fuel injector to foul. If such a condition occurs, you should contact the nearest HATZ authorized Service Center
for necessary repairs.
The engine is designed and adjusted to operate most efficiently at the following 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 performance 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. However if you must operate your equipment under
very unusual climatic conditions, please contact your nearest Hatz distributor for advice.
